Context: A cluster and increase in pneumonia cases with unknown cause were detected in Wuhan, Hubei province, China, in December 2019. These cases were reported to be associated with a new coronavirus type by the Chinese health authorities on January 7, 2020. The first case in Turkey was diagnosed on March 11, 2020. COVID-19 (SARS-CoV-2 infection) guide was prepared for the pandemic by the Ministry of Health scientific committee. However, despite strong clinical, laboratory and radiological suspicions, there are also patients who do not meet the exact case definition. Case report: In this case report, we aimed to discuss two cases that did not meet the definitive case definition and followed up in our clinic. Conclusions: Although gold standard method for the definitive diagnosis of SARS-CoV-2 infection is PCR, rapid antibody tests and CT findings are used in combination with PCR for a more effective struggle in the pandemic process would enhance rapid diagnosis of cases, necessary treatment and isolation measures to prevent transmission. It is thought that it would be useful to make case definitions.

The novel corona or COVID-19 disease spread from Wuhan city of China. The virus spread rapidly around the different countries, and now there are 6,040,609 confirmed cases across the globe. People inflected with virus are suffering from respiratory problems, blood clotting, etc. It is evident to be more dangerous for older persons and those who are already facing other serious illnesses. The virus spreads mainly through droplets of saliva or discharge from the nose of infected person when he coughs or sneezes. The purpose of this review is to focus on social and economic impact of COVID-19 in India and how the world will change because of this pandemic and what will be the ‘new normal' with and after this pandemic. This deadly virus has put the globe on alert because of its the high mortality rate and expansion of new number of cases rapidly. Until now, four lockdown phases had helped India to prevent the spike in the curve of new cases, but currently the authors are witnessing steeper rise in new corona cases every day.

Objective: To determine association of anosmia as an early symptom of COVID-19 infection. Study Design: Comparative cross sectional study. Place and Duration of Study: ENT department, Combined Military Hospital, Quetta, from Apr to Oct 2020. Methodology: A total of 6411 consenting patients with symptoms of viral upper respiratory tract infection presenting at ENT department, Combined Military Hospital Quetta, from Apr to Oct 2020 were tested for COVID 19 via PCR studies. Results: Out of 6411 individuals 1109 (17.3%) were found to be COVID positive and 5302 (82.7%) were COVID negative. Of the COVID positive cases 611 (55.1%) of COVID positive individuals had anosmia, whereas only 68 (1.2%) of COVID negative individuals had anosmia, this observation was statistically significant (p<0.001 on chi square test). Whereas only 33 (2.9%) patients had nasal obstruction in COVID positive group, and 68 (1.2%) cases in COVID negative group had nasal obstruction, this observation was not statistically significant (p>0.05 on chi square test). Conclusion: Anosmia has a definite association with COVID 19 infection.

Successful vaccination has been the decisive factor in the overall decline of SARS-CoV2 infection related morbidity and mortality. However, global effects of the COVID-19 pandemic are ongoing, with reports of glomerular disease occurring in relation to both infection and vaccination. A particular rise in anti-GBM disease has been identified. Information is still emerging regarding the optimal management of such cases. We reviewed anti-GBM antibody detection rates at our test center over the past 5 years. We followed three patients with biopsy confirmed glomerular disease temporally related to COVID-19 vaccination. Each patient proceeded to receive subsequent COVID-19 vaccination as per immunologist recommendations. Further assessment included COVID-19 antibody testing in each case. A three-fold increase in significant anti-GBM antibody results noted at our center was associated with COVID infection in 10% of cases, and COVID vaccination in 25% of cases. We demonstrated that subsequent vaccination did not appear to lead to adverse effects including relapse in our three cases of COVID-19 vaccine-associated GN. We also identified positive COVID-19 antibody levels in two out of three cases, despite immunosuppression. We report a rise in anti-GBM antibody disease incidence. Our small study suggests that COVID-19 antibody testing can help determine COVID prophylaxis requirements, and subsequent vaccination with an alternative vaccine type appears safe.

Background: Homoeopathy is a medical science that should be practiced with evidence. As a practitioner, I was keen to show how Homoeopathy can give relief in this pandemic where conventional therapy was also struggling to offer treatment. Homoeopathic remedies given in Covid-19 cases in my OPD were prescribed to patients 1. who took only Homoeopathy, 2. who took Allopathy but got no relief and 3. hospitalized yet got relief with Homoeopathy. Few cases which did not get symptomatic relief were advised to stop treatment. Aims: To see the efficacy of Homoeopathy in treating covid 19 patients – with mild, moderate, and severe symptoms. Methodology: Data collected after permission from the patients to share case studies for Homoeopathy treatment of Covid-19 were obtained from GraceHealing Homeopathy clinic in Nagpur were categorized as mild to moderate and moderate to severe as per AYUSH guidelines; similimum with matching potency prescribed after detailed case inquiry, and regular Follow-ups were done until patients felt relief. Hypothesis: To see the action of Homoeopathy similimum - as a palliative, curative, and no action in treating covid-19 cases. Results: Homoeopathy has shown definite results in mild to moderate and moderate to severe cases up to 80% relief in mild to moderate 60% in moderate to severe. Mild to moderate cases where only Homoeopathy was given: China-ars, Ferrum-p, and Gelsemium were satisfactory. Baptisia and Carb-v adjuvant to Allopathy was also satisfactory. In hospitalized severe case gave relief, where Allopathy did not help. If Homoeopathy was given in such cases, it acts in increasing the immunity to make healing faster: Kali carb and Nux vomica satisfactory. Conclusion: With detailed case inquiry, symptomatic treatment with simillimum in correct potency can give Covid 19 patients relief.

Questions persist as to the origin of the COVID-19 pandemic. Evidence is building that its origin as a zoonotic spillover occurred prior to the officially accepted timing of early December, 2019. Here we provide novel methods to date the origin of COVID-19 cases. We show that six countries had exceptionally early cases, unlikely to represent part of their main case series. The model suggests a likely timing of the first case of COVID-19 in China as November 17 (95% CI October 4). Origination dates are discussed for the first five countries outside China and each continent. Results infer that SARS-CoV-2 emerged in China in early October to mid-November, and by January, had spread globally. This suggests an earlier and more rapid timeline of spread. Our study provides new approaches for estimating dates of the arrival of infectious diseases based on small samples that can be applied to many epidemiological situations.

Spontaneous pneumomediastinum is a rare complication of viral pneumonia. The prevalence of pneumomediastinum among coronavirus infection patients is unknown.Subjects and methods. Three cases of spontaneous pneumomediastinum among the COVID-19 pneumonia patients were analyzed. The researchers investigated and compared clinical, radiological and laboratory data.Results. According to the research results, no correlation was found between the development of pneumomediastinum and changes in values of blood laboratory tests. As well as there were no signs of correlation between drug treatment and pneumomediastinum frequency.Conclusion: The researchers suggest that the leading cause of spontaneous pneumomediastinum is viral pneumonia-associated severe alveolar damage.

The severe acute respiratory syndrome (SARS)-coronavirus-2 (CoV-2) outbreak in Wuhan, China has now spread to many countries across the world including the UK with an increasing death toll. This will inevitably lead to an increase in the number of suspected coronavirus disease 2019 (COVID-19)-related deaths at autopsy. The Royal College of Pathologists has responded to this concern with the release of a briefing on autopsy practice relating to COVID-19. The following article is a summary and interpretation of these guidelines. It includes a description of hazard group 3 organisms, the category to which SARS-CoV-2 has been assigned, a brief description of what is currently known about the pathological and autopsy findings in COVID-19, a summary of the recommendations for conducting autopsies in suspected COVID-19 cases and the techniques for making the diagnosis at autopsy. It concludes by considering the clinicopathological correlation and notification of such cases.

The steadily growing COVID-19 pandemic is challenging health systems worldwide including Sudan. In Sudan, the first COVID-19 case was reported on 13th March 2020, and up to 11 November 2020 there were 14,401 confirmed cases of which 9,535 cases recovered and the rest 3,750 cases were under treatment. Additionally, 1,116 deaths were reported, indicating a relatively high case fatality rate of 7.7%. Several preventive and control measures were implemented by the government of Sudan and health partners, including the partial lockdown of the country, promoting social distancing, and suspending mass gathering such as festivals and performing religious practices in groups. However, new cases still emerging every day and this could be attributed to the noncompliance of the individuals to the advocated preventive measurements.

: Corona virus disease-2019 (COVID-19) is associated with various opportunistic, bacterial, and fungal infections. High risk groups include people with diabetes especially diabetic ketoacidosis, solid organ transplantation, long-term systemic corticosteroid use, and iron overload. Many cases of mucormycosis were reported worldwide. Mucormycosis is an invasive fungal infection with high morbidity and mortality. Early diagnosis and treatment with appropriate anti-fungals lead to improved outcomes. The aim of this study is to establish the factors associated with mucormycosis in a COVID-19 setting, like comorbidities and treatment protocols for treatment of COVID-19. The histological patterns and tissue reactions to mucormycosis also were studied. In patients with ongoing COVID-19 infection and in a post COVID-19 scenario, we studied the biopsy findings of mucormycosis in various sites like rhino-orbital, lung, gastric and trachea. Material for this study is from a tertiary care hospital in South India. Patient age ranged from 30 years to 74 years. Mean age of the patients was 51 years. Male to female ratio was 1:1.1. Tissue from sino- nasal mucosa, peri orbital tissue, exenterated eyeball, lung tissue and tissue from rare sites like gastric and tracheal mucosal lesions were also included in this study. Tissue was fixed in 10% buffered formalin. Routine Haematoxylin and Eosin(H&E) stains were done. Gomori’s Methenamine silver (GMS) stains were done on all cases. Tissue was submitted for fungal cultures in all the cases.Total of twenty-three cases were diagnosed as mucormycosis based on the morphology and special stains in this analysis. Histology revealed areas of infarction in all cases with neutrophilic infiltration. Granulomatous reaction was seen in seven cases and melanin pigment was seen in two cases. 100% of patients were diabetics. There was neutrophilia in 100% of cases. Lymphopenia was seen in 85.7%, C-Reactive Protein (CRP) was elevated in 100% of cases.Ferritin was done in 14 patients and D-dimer was done in 17 patients and in all patients, these were elevated. All patients were treated with steroids according to the treatment protocol for COVID-19, Remdesivir was given in 72.7% of cases and second immunomodulator drugs like Tocilizumab in four cases and Baricitinib in one case.Mucormycosis is an emerging problem with COVID-19. It is important to carefully monitor blood glucose levels and take into account underlying medical conditions of patients before initiation of steroid therapy. Early recognition of symptoms and early diagnosis has a better outcome in patients with mucormycosis associated with COVID-19 infection.

COVID-19 transmission can be controlled through RT-PCR and RDT-Ag diagnostic tests, yet neither test performs well. This has encouraged people to search information for the COVID-19 pandemic response and exposure fears on Google. Therefore, this study analyzes the correlation between COVID-19 diagnosis tracing on Google and new COVID-19 cases in Indonesia. An explanatory mixed method study design was used. A quantitative study was done using time-lag correlation between the keywords, namely “Antigen”, “Swab” dan “PCR” based on Google Trends™ (https: // trend.Google.com/trends) from 13 July 2020 to November 2021. The search peaks for diagnosis and their geographical distribution were described qualitatively. There is a correlation between COVID-19 diagnosis searches on the keywords Swab (r = 0.787, P-Value = 0.000) and Antigen (r = 0.378, P-Value = 0.003) with COVID-19 new positive cases. The cumulative number of daily tests is also correlated with COVID-19 diagnosis searches (r = 0.617, P-Value = 0.000 (PCR keywords) and r = -0.337, P-Value = 0.003 (Keywords Swab)). There was also a correlation between searches for COVID-19-related keywords PCR, Swab, and Antigen and the frequency of daily PCR and Antigen tests (P-Value <0.005). Google Trend has the potential as a monitoring tool for people's diagnosis behavior. Further study of Google Trends is required to strengthen the potential of Google Trends for monitoring COVID-19 cases in Indonesia.

Background: Triaging of COVID-19 patients. Coronavirus disease 2019 (COVID-19) pandemic has posed a threat both to lives of common people as well as to the existing overburdened healthcare system. There has been dearth of hospital beds which has lead to chaos. In such a situation triaging of patients is of utmost importance to avoid unnecessary hospital admission which results in both anxiety in patients and increases load on hospitals. We hereby propose a scoring system which incorporates all the points that must be seen in suspected and tested positive COVID-19 patients and gives a score following which patients can be divided into different stages as per severity namely mild, moderate and severe. Mild cases can be advised for home quarantine/isolation with warning signs explained and this reduces unnecessary admissions. Moderate and severe cases which requires admission can be triaged with respect to ward and intensive care unit (ICU) admissions. This prevents unnecessary ICU admissions as well as prevents delay in ICU shifting of moderate cases on deterioration.Methods: We have conducted a cross-sectional study on 500 suspected and real time-polymerase chain reaction (RT-PCR) tested positive COVID-19 patients using this scoring system in order to triage them.Result: Out of 500 patients including both suspected and positive COVID-19 patients only 373 required admissions whereas 127 admissions were successfully avoided as they could be sent for home quarantine/isolation.Conclusion: Triaging of patients, especially during a pandemic where the case load is immense, is very important. Presence of a concise score which incorporate all important points serves the purpose.

Streszczenie:

Since the primary mode of Covid transmission is person-to-person contact both through respiratory droplets produced by sneezing, breathing, coughing and direct contact with an infecting subject or indirect through hand-mediated transfer of the virus, governments had to limit the contact between individuals to reduce the risk of coronavirus infection. The effect has been a drastic reduction of human interactions, as these were “cut to the bone”. The strict rules the world population has been following, have brought about an urgent debate on the behaviour and regulations that governments have embraced. Fundamental questions about democracy and social theory have been raised by scholars and theorists seeking for a possible answer about why, how and whether the Covid-19 emergency has caused a transformation in a society and, if it is so which are the effects and where are we heading. The paper will be divided in two sections: the former is focused on different perspectives on the impact of Covid-19 and aims to understand whether a western democracy can handle a borderline case like this, or does it have to develop into some other social system. The latter section will focus on what the Covid emergency has been causing in a society and how governments have decided to control and face this situation.

Introduction: The SARS-COV 2 virus, in particular in its severe form, appears to be associated with a large number of thromboembolic events, an incidence all the higher as the patients are admitted to intensive care units or intensive care units. The objective of our work is to identify the prognostic factors for the occurrence of thromboembolic complications of covid 19 in intensive care. Material and method: It is a single-center retrospective study, carried out in the intensive care unit of the IBN TOFAIL hospital in Marrakech. We included all covid 19 patients hospitalized from November 15, 2020 to January 10, 2021 confirmed by RT-PCR or by compatible CT lesions. The qualitative variables were expressed in% and compared by Chi-square test or Fisher's test. The quantitative variables were expressed as a mean (± standard deviation) or as a median (Percentile), and compared by Student's or Mann-Whitney t-test. For multivariate analysis, we used multiple logistic regressions using SPSS version 19 for Windows. A p <0.05 is considered significant. Results: We collected 102 patients hospitalized with SARS-COV 2 pneumonia during the study period. The mean age was 61.81 ± 11 with a predominance of men (65.7%), 45.4% of the patients had a BMI between 30-34.9 Kg / m². Diabetes predominates in 59.8% followed by hypertension in 40.2%, heart disease, dysthyroidism and renal failure were observed in 8.8%, 3.9% and 3.2% of cases, respectively. Forty-two percent of patients presented with coagulopathy on admission, defined by D-Dimer levels> 0.5µg / ml, fibrinogen> 4g / l and thrombocytopenia. The occurrence of an arterial or venous thromboembolic event was found in 24.5% of cases with mainly venous manifestations, i.e. thirteen pulmonary embolisms, three catheter thromboses and two deep vein thromboses and five arterial accidents represented by three ischemic strokes, two limb ischemia and one myocardial infarction. The presence of this coagulopathy associated with ............

<p><strong>Background and objective:</strong> as COVID-19 has triggered enormous human casualties and disastrous economic loss, the strategies to contain its spread are urgently needed. We aim to assess the value of our suspect case strategy on COVID-19 cases detection and ensure it to be a complement to the RT-PCR test. <strong>Materials and methods:</strong> from January 23 to April 30, 2020, patients admitted to our emergence isolation ward (EIW) were analyzed in this study. With RT-PCR as a reference standard, all participants were assigned to COVID-19 positive and negative groups. We compared the performance of the suspect case strategy, WBC, LYM, and chest radiography on COVID-19 detection. <strong>Results:</strong> one hundred twenty-five cases were analyzed in the study period. The receiver operating characteristic (ROC) curve revealed the sensitivity of WBC and LYM on COVID-19 detection was 92.11% and 76.31%, respectively. The sensitivity of the suspect case was 94.73%, and the sensitivity of chest CT was 53.33%. Statistically significant differences were observed for the suspect case, WBCs, LYM, and chest CT on COVID-19 detection. <strong>Discussion:</strong> suspect case strategy can help identify false negative RT-PCR tests and be a useful complement to RT-PCR in some countries with a tremendous shortage of RT-PCR agents and specialized laboratory during the COVID-19 outbreak.</p>

The main objective of this study was to evaluate the retinas of severely or critically ill COVID-19 patients during their hospital stay, at varying time points after symptoms onset. This was a case series observed during May 2020 in two referral centers for COVID-19 treatment in Rio de Janeiro, Brazil. 47 eyes from 25 hospitalized patients with severe or critical confirmed illness were evaluated. A handheld retinal camera was used to acquire bilateral fundus images at several time points after symptoms onset. Electronic health records were retrospectively analyzed and clinical data collected. Severe and critical diseases were noticed in 52% (13/25) and 48% (12/25) of enrolled patients, respectively. Retinal changes were present in 12% (3/25) of patients: a 35 year-old male demonstrated bilateral nerve fiber layer infarcts and microhemorrhages in the papillomacular bundle, but required mechanical ventilation and developed severe anemia and systemic hypotension, acute kidney injury and neurologic symptoms during the course of the disease (critical illness); a 56 year-old male, who required full enoxaparin anticoagulation due to particularly elevated D-dimer (>5.0 mcg/mL), demonstrated unilateral and isolated flame-shaped hemorrhages; and a 49 year-old hypertensive male showed bilateral and discrete retinal dot and blot microhemorrhages. The other 22 patients evaluated did not demonstrate convincing retinal changes upon examination. There was no correlation between disease severity and admission serum levels of CRP, D-dimer and ferritin. This was the first study to show that vascular retinal changes may be present in not insignificant numbers of severe or critical COVID-19 inpatients. These retinal changes, only seen after morbid developments, were likely secondary to clinical intercurrences or comorbidities instead of a direct damage by SARS-CoV-2, and may be important and easily accessible outcome measures of therapeutic interventions and sentinels of neurologic and systemic diseases during COVID-19 pandemic.

It has been happened a significant increase of critically severe pneumonia cases in northern Italy by the end of February 2020 with consequent overcrowding of intensive care units (ICU). Due to the COVID-19 fast outbreak, a strict quarantine was imposed in the areas with the higher number of affected cases. The WHO declared COVID-19 a pandemic, with over 50 countries on the 10th of March. By the 10th of March Italy was the second most affected country after China, with more than nine thousand confirmed cases and more than 460 deaths, becoming the most affected in April.

Coronavirus disease (Covid-19) caused a pandemic severely affecting various sectors and paralyzed health services in Indonesia. As of June 2020, the percentage of Covid-19 confirmed cases in Kalimantan, the second largest island in Indonesia, contributed about 7% of the total national cases. In the same period, the percentage of Covid-19 deaths reached 12% of the national figure. This study used regression models to respond to bi-response count data consisting of Covid-19 confirmed cases and Covid-19 deaths in regencies/cities in Central Kalimantan and South Kalimantan provinces. This study compared the results of bivariate Poisson regression and bivariate negative binomial regression. There were thirteen predictors representing the determinants of health, social, economic, and demography indicators. The results showed that the prevalence of pneumonia had positive effect on Covid-19 confirmed cases and Covid-19 deaths. The percentage of elderly had negative effect on confirmed cases, while it had no significant effect on Covid-19 deaths. Bivariate negative binomial regression showed more satisfying performance on modeling Covid-19 cases and Covid-19 deaths jointly because it produced lower AIC and deviance than that of Poisson one. The negative bivariate model was also better than the Poisson one because it was able to overcome over-dispersion.

During the COVID-19 pandemic, divorce cases in the city of Tangerang experienced an increase. In particular, this paper aims to identify how high divorce cases occurred during the pandemic, but also to analyze the factors/conditions that led to an increase in divorce cases based on the results of religious court decisions regarding divorce. This study uses a qualitative approach with a descriptive analytical approach that utilizes data sourced from scientific articles in Google Scholar, Garuda, Sinta and journals managed by various institutions. The understanding of divorce in marriage according to the Islamic point of view is the last door when there is no way out to solve problems that occur in the household. And in article 39 of the marriage law it is explained that divorce can only be carried out in front of a court session and not with a court decision. The divorce rate in Tangerang City throughout 2021 is 3,545 cases. This figure has increased by about 14 percent compared to 2020 with 3,041 cases. In 2020 the highest cause of divorce is economic with 6,001 cases, and in 2021 the highest cause of divorce is disputes and quarrels with 2,026 cases. This increase in divorce certainly results in several impacts, such as psychological weakness in children, traumatic events, changes in roles and status, to difficulty adjusting. The government needs to pay special attention to increasing divorce cases by optimizing mediation by religious courts.

Background: This study aimed to determine the secondary attack rate (SAR) and its determinants to describe the clinical features and epidemiological aspects of patients and determine the risk factors of COVID-19 among household contacts in Hamadan Province, west of Iran. Study design: A cohort study. Methods: In this cohort study, a total of 323 index cases and 989 related close contacts ages more than 15 years old (family members, relatives, and co-workers) were enrolled using a manual contact tracing approach, and all participants were tested by reverse transcription polymerase chain reaction test. In this research, the frequency of symptoms was assessed, the SAR among contacts of index cases was calculated, and the risk factors of COVID-19 were evaluated by the logistic regression model. Results: The secondary attack rate for total household members of index cases was estimated at 31.7% (95% CI: 28.8-34.7). It was found that among household contacts, the highest SARs were related to spouses 47.1% (95% CI: 38.7-55.7) and grandparents/parents 39.3% (95% CI: 29.4, 49.9) of index cases, who had also higher risks to become secondary cases (adjusted odds ratio [OR]=2.98, 95% CI: 1.31-6.75 and adjusted OR=2.76, 95% CI: 1.18-6.44, respectively). Considering the occupation of contacts, unemployed and retired people and housewives were most susceptible for transmission of COVID-19. It was revealed that cough was the most prevalent symptom among index and secondary cases. Conclusions: Our findings indicated that spouses and grandparents/parents of index cases were the most susceptible individuals for COVID-19 transmission. Prolonged exposure with index case before COVID-19 diagnosis raised the chance of infection among secondary cases.

COVID-19 is a rapidly spreading global threat that has been declared a pandemic by WHO. COVID-19 is transmitted through droplets or direct contact and infects the respiratory tract causing pneumonia in most cases and acute respiratory distress syndrome (ARDS) in about 15% of cases. Deaths in COVID-19 patients have been linked to so-called "cytokine storms" caused by the virus. Overproduction of proinflammatory cytokines leads to worsening of ARDS and extensive tissue damage resulting in multi-organ failure and death. Suppressing cytokines during the management of COVID-19 patients can increase survival rates and reduce mortality.

Coronavirus disease 2019 (COVID-19) was initially recognized in late December 2019 and has quickly spread globally with over 114 million reported cases worldwide at the time of this publication. For the majority of patients infected with COVID-19, the clinical manifestations are absent or mild. In more advanced cases, severe respiratory dysfunction is the leading cause of morbidity and mortality. However, increasingly, there have been reports of increased thrombotic complications including pulmonary embolism and deep vein thrombosis seen in these patients. We present herein a series of cases of concomitant COVID-19 pneumonia and venous thromboembolism. These cases highlight the importance of clinical and radiologic vigilance to ensure this often clinically silent complication is not missed.

Much has been said in the popular press about the world-wide COrnaVIrus Disease 2019 (COVID-19) pandemic. Some of this information is accurate, some is exaggerated. In some cases vital information has not been presented, while other information is simply wrong. As business activity resumes in the U.S. and other countries, occupational health and safety personnel will have to make some extremely difficult decisions. Those decisions will have to be based on a thorough understanding of the scientific facts and not fear, partial information or distortions. So, what are the facts? What is a coronavirus? How does it work? How did it get that name? Where did it come from? How does it spread? Is there any way to stop it? Do masks work? What about social distancing, hand sanitizers and hand washing? What do the coronavirus statistics mean? Can a vaccine be made? Does post-infection therapy work, and is it safe? Does vitamin C and zinc do anything, or is it just a hoax? These are some of the questions that will be addressed in this article.

The global context towards sustainable development has essentially changed with the COVID- 19 pandemic. The world faces the greatest social, economic and environmental challenges. This pandemic is characterized by its rapid spread, differential recovery rate and susceptibility to elderlies and people with weak immune systems. The impact of COVID-19 lockdown can distract the management plan and exacerbate the prognosis of non-COVID-19 patients. There are many lessons the world can learn from this disastrous pandemic outbreak for us to revise and strategize an efficient disaster management system which includes non-COVID-19 cases. The survival of non-COVID-19 cases is still a mystery as the pandemic waves are always uncertain. The key to unlocking the secret is the balancing-resilience strategy in the new normal disaster management framework. This pandemic offers an opportunity to make the world resilient to multiple hazards while sustaining the best care for non-COVID-19 patients.International Journal of Human and Health Sciences Supplementary Issue: 2022 Page: S5
