Study finds short window for donating convalescent plasma to COVID-19 patients

The optimal timeframe for donating convalescent plasma for use in COVID-19 immunotherapy, which was given emergency-use authorization by the Food and Drug Administration in August 2020, is within 60 days of the onset of symptoms, according to a new Penn State-led study.

Study finds short window for donating convalescent plasma to COVID-19 patients

The optimal timeframe for donating convalescent plasma for use in COVID-19 immunotherapy, which was given emergency use authorization by the Food and Drug Administration in August 2020, is within 60 days of the onset of symptoms, according to a new study. The research also reveals that the ideal convalescent plasma donor is a recovered COVID-19 patient who is older than 30 and whose illness had been severe.

Reducing transmission risk of livestock disease

The risk of transmitting the livestock virus PPRV, which threatens 80% of the world’s sheep and goats, increases with certain husbandry practices but not herd size. A new study, led by researchers at Penn State, investigated how transmission of PPRV might change at different scales and identified specific husbandry practices associated with increased odds of infection — including the introduction of sheep and goats to the herd, sheep or goat attendance at seasonal grazing camps, and the sales or gifting of goats from the herd.

Efforts to control livestock disease should focus on management style, not age

The risk of transmitting the virus PPRV, which produces a highly infectious and often fatal disease in sheep and goats, does not appear to vary significantly by an animal’s age, unlike its sibling virus measles, which is most prominent in children.

Livestock disease risk tied to herd management style in Tanzania

A new study provides an updated picture of the prevalence of the sheep and goat plague virus (PPRV), a widespread and often fatal disease that threatens 80 percent of the world’s sheep and goats, in Northern Tanzania.
