In a prospective, longitudinal study, N-antibodies peaked 90–100 days after infection and persisted for at least 500 days in most patients. The duration of antibody response after SARS-CoV-2 infection is not clearly established, although prior studies have estimated that antibodies produced after natural infection last from 3 to 6 months. […]
A chain of events possibly triggered by unrecognized infection with the SARS-CoV-2 coronavirus could be causing the mysterious cases of severe hepatitis reported in hundreds of young children around the world, researchers suggest. Children with COVID-19 are at significantly increased risk for liver dysfunction afterward, according to a report posted […]

Multisystem inflammatory syndrome in children (MIS-C) is a serious complication of SARS-CoV-2 infection.1 A previous study that described MIS-C cases in the first 3 waves of the COVID-19 pandemic found that the proportion of individuals with severe illness declined after the first wave.2 In Israel, the Omicron (B.1.1.529) variant started to spread […]
SARS-CoV-2, or at least pieces of it, sticks around longer in some infected individuals than respiratory sample testing would suggest, a recent study found. After respiratory samples tested negative, a small proportion of the 113 study participants continued to shed SARS-CoV-2 RNA in their feces—about 4% of them for at least […]
The FDA expanded an emergency use authorization (EUA) today allowing the Pfizer-BioNTech COVID-19 booster shot for children between the ages of 5 to 11 who are at least 5 months out from their first vaccine series. According to the most recent data from the Centers for Disease Control and Prevention, […]
The widespread availability of at-home COVID-19 tests have made it easier for people to know if they have the virus, and to take measures to protect themselves and others. But there is a downside. Because the majority of tests are now done at home and often not reported, the official counts on […]
Un equipo de médicos encontró que la calculadora de riesgo quirúrgico ACS NSQIP, del American College of Surgeons (ACS), predice la mayoría de complicaciones posoperatorias y estima los días de estancia hospitalaria de pacientes mexicanos operados en un escenario de urgencias.[1] Y aunque no fue eficaz para predecir neumonía, infección de vías urinarias o readmisión hospitalaria, […]
Older patients in Israel who received a fourth dose of the BNT162b2 (Pfizer-BioNTech) SARS-CoV-2 vaccine were more than 3 times less likely to develop severe COVID-19 than those who received only 3 doses. But while protection against severe disease did not wane during the testing period, protection against confirmed infection […]
Rising COVID-19 case numbers and hospitalizations likely mean we’re in a new phase of the pandemic. And the number of Americans dying from COVID-19 is also anticipated to grow, although the surge in the short term is not expected to look like previous waves. That’s the takeaway from a team […]
