New genetic epidemiology tool provides detailed information about viruses, coinfections

With mask wearing and social distancing on the decline and the cold and flu season upon us, researchers have developed a viral panel that enables the simultaneous testing for SARS-CoV-2 along with numerous common respiratory viruses, that tells us whether other viruses also are at play in patients hard hit by COVID.

COVID-19 antibody levels stay more durable in vaccinated people with prior SARS-CoV-2 infection

In what is believed to be one of the largest studies of its kind, Johns Hopkins Medicine researchers have shown that antibody levels against SARS-CoV-2 (the COVID-19 virus) stay more durable — that is, remain higher over an extended period of time — in people who were infected by the virus and then received protection from two doses of messenger RNA (mRNA) vaccine compared with those who only got immunized.

Routine surveillance helps detect asymptomatic SARS-CoV-2 vaccine breakthrough infections

In a study published in Annals of Internal Medicine, researchers from Italy systematically monitored 2,397 HCWs who were fully vaccinated with BNT162 at the ASST Settelaghi hospitals in Lombardy, Italy during February 2021. HCWs who worked in 8 wards deemed at “high risk” for infection from attending patients had to undergo mandatory nasopharyngeal swab testing with SARS-CoV-2 polymerase chain reaction every two weeks. HCWs working in 8 “moderate-risk” wards were tested every four weeks.
