Immunologists Prakash Nagarkatti and Mitzi Nagarkatti of the University of South Carolina explain what makes it different from previous variants, whether there will be another […]
Alarge study comparing brain scans from the same individuals before and after SARS-CoV-2 infection suggests that brain changes could be a lingering outcome of even mild COVID-19. Writing in Nature, researchers at Oxford University’s Wellcome Centre for Integrative Neuroimaging reported that several months after study participants had SARS-CoV-2 infections, they had more gray […]
The US Department of Health and Human Services (HHS) has purchased 600 000 treatment courses of bebtelovimab—a monoclonal antibody that research shows effectively treats the SARS-CoV-2 Omicron variant. Omicron is currently responsible for almost all COVID-19 cases in the US, according to an HHS statement. “We want to make sure if an […]
U.S. communities with limited internet access reported higher COVID-19 death rates during the first year of the pandemic, according to a recent study published in JAMA Network Open. Between 2.4 and six deaths per 100,000 people could have been prevented, the researchers estimated, depending on whether they were in rural, suburban or urban […]

A new systematic literature review suggests that there may be – at most – a weak link between COVID-19 and alopecia areata. If there is a connection, it’s likely not a strong one, said study author Rachel E. Christensen, a graduate student at Rutgers Robert Wood Johnson Medical School, in an […]
In this open-label, nonrandomized clinical study, we assessed the immunogenicity and safety of a fourth dose of either BNT162b2 (Pfizer–BioNTech) or mRNA-1273 (Moderna) administered 4 months after the third dose in a series of three BNT162b2 doses (ClinicalTrials.gov numbers, NCT05231005. opens in new tab and NCT05230953. opens in new tab; the protocol is available with […]
Los pacientes que se recuperan de COVID-19 muestran anomalías cognitivas, de electroencefalografía y de resonancia magnética interrelacionadas 2 meses después del alta hospitalaria, y algunas “alteraciones” persisten hasta 10 meses después, sugiere una nueva investigación.[1] En una cohorte de pacientes ingresados en el Servicio de Urgencias con diagnóstico de COVID-19, […]
Aerosolized hydrogen peroxide (aHP) can significantly reduce Clostridioides difficile infection (CDI) and is an effective disinfection system, suggests a new study published in the American Journal of Infection Control. C. difficile is the most common cause of healthcare-associated infection and increasingly occurs outside acute care hospitals. CDI symptoms can range from mild diarrhea to life-threatening colitis and sepsis, sometimes requiring urgent colon removal. […]
