Investigating the links between the rate of new cases, mutations, and selection in SARS-CoV2 virus

How many times in the last 18 months have you seen a map that looks like the one above? It looks like a population density map, but in fact, it is a case total for the COVID19 rates from Johns Hopkins Coronavirus Research Center (collected on 24 May 2022).

Researchers explored neutralizing antibodies against SARS-CoV-2 Omicron BA.1, BA.2, and BA.5 lineage infected patients.

25 Aug 2022

The role of SARS-CoV-2-specific T cells induced by infection, vaccination, or their combination in disease protection

Researchers evaluated how SARS-CoV-2-specific-T lymphocytes induced by infection, vaccination, or both conferred protection against severe COVID-19.

SARS-CoV-2 variants of concern emerging from chronic COVID infections, study shows

The coronavirus variants of concern are emerging from chronic, long-term COVID infections in people who may be immune comprised and unable to clear the virus, a new study strongly suggests.

23 Aug 2022

Analysis finds link between regular physical activity and lower risk of COVID-19 severity

Regular physical activity is linked to a lower risk of COVID-19 infection and severity, including hospital admission and death, finds a pooled data analysis of the available evidence, published online in the British Journal of Sports Medicine.
