This study corroborates the earlier study by Long et al. in the Chinese population (doi: 10.1038/s41591-020-0965-6), which demonstrated that 40% of asymptomatic patients were seronegative for IgG at 8 weeks. The decline in protective antibody titre is quicker than...

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...
