This study has important public health implications and shows the risk of using COVID-19 ‘immunity passport’. Since immunological responses may vary among different ethnic groups, such temporal seroprevalence surveys in the community are required in different...

The correct method of testing for COVID-19 antibodies is important in the current phase of the pandemic when gradual re-opening of the workplace is being contemplated.In India, rapid antibody tests were introduced early in the epidemic and then withdrawn due to...

The study delves into COVID-19 household transmission dynamics which can guide home isolation policy in non-severe COVID-19 cases. It suggests minimal risk of COVID-19 transmission among household contacts if early and strict isolation (masking, eating and residence)...

Although earlier publications have mentioned the presence of viral particles in the urine, this is the first report of autopsy findings in COVID-19 substantiating that the virus directly invades the kidney. As kidney or other organ biopsies are unlikely to be done as...

The study provides evidence, under laboratory conditions, of the number of droplets produced by loud speech and their airborne duration suggesting a plausible role of speech droplets in the transmission of SARS-CoV-2 in confined spaces. Article: Stadnytskyi V, Bax CE,...

Autopsies are gold standard to identify the cause of death and study pathophysiology of novel diseases. Though the studies are less as compared to number of deaths worldwide, findings of pulmonary artery thrombosis and thromboembolism in these studies underpin and...

This study suggests that among patients undergoing major surgery who are positive for SARS-CoV-2 there is a high risk of mortality and morbidity. There is a significant influence of age on postoperative mortality with younger patients (<50 years) having a better...

This study, authored by surgeons from Israel, is a review of 4 articles where elective or semi-elective surgery was performed for COVID-19 cases without testing for SARS-CoV-2. More than 50% severe disease and 27.4% mortality in such patients is of concern. All...

The study has major implications for judicious resource use as epidemic nears the peak and health system capacity is stretched. While in Wuhan, every patient with mild illness was isolated in the hospital or other isolation facilities for a prolonged period, this is...

This validation cohort preliminary study had a very good inter observer agreement between the reading radiologists, and the overall CXR score was a good parameter to evaluate severity and outcomes, however there is need for larger study for validation. In the current...

Only a small percentage of affected COVID patients develop severe illness. Hence a predictive score is useful for the clinician. This study puts forward a simple risk calculator for predicting development of severe illness in COVID-19 patients at the time of...

The study explores for the first time the landscape of bronchoalveolar immune cells revealing aberrant macrophage and T cell responses underlying immunopathogenesis in COVID-19 and thus could be a landmark both in the pathogenesis and management of COVID-19. Article:...

The existing literature suggests that infrared thermometer may miss a significant fraction of patients with pyrexia, giving a false sense of safety. The handheld infrared thermometer does not measure the temperature accurately. The personal experience of the...
