High seroprevalence in Peruvian population recovering from SARS-CoV-2 infection

By the middle of 2020, Iquitos, Peru, had the highest number of SARS-CoV-2 antibodies in the world. Despite natural immunity, the city experienced a second coronavirus wave, with reinfections possibly owing to the P.1 variant.

Landmark study confirms that controlled blood pressure is key to prevent stroke, heart disease

Follow-up data from the landmark SPRINT study of the effect of high blood pressure on cardiovascular disease have confirmed that aggressive blood pressure management -- lowering systolic blood pressure to less than 120 mm Hg -- dramatically reduces the risk of heart disease, stroke, and death from these diseases, as well as death from all causes, compared to lowering systolic blood pressure to less than 140 mm Hg.

Pfizer-BioNTech vaccination not associated with platelet activation in new study

Among the devastating complications of severe or critical coronavirus disease 2019 (COVID-19), clot formation ranks high in the adverse impact it creates. An important question is whether SARS-CoV-2-spike-based vaccines also cause such coagulopathies. A new study, released as a preprint on the medRxiv* server, examines this risk for the first time.

Risk factors for rare COVID-19 complications in children (MIS-C)

While the earlier waves of COVID-19 relatively spared children, some of the affected children have developed a systemic inflammatory condition, with occasionally fatal outcomes. Called multisystem inflammatory syndrome in children (MIS-C), its pathogenesis and risk factors are the subject of a new study on the medRxiv* preprint server.

Facets of SARS-CoV-2 infection and animal models

A new study in the journal Frontiers in Cell and Developmental Biology discusses the ribonucleic acid (RNA) genome of the virus, and the mechanisms by which it establishes infection within the host cell. The researchers also summarize the development of animal models of COVID-19, which will both help understand the clinical features of the illness, and indicate new approaches for the treatment of the infection.
