‘Flurona’ is real, but don’t panic — it’s common to get two viruses at once

No, flurona is not some scary new variant of the coronavirus. And — do we really need to say this? — it is not an actual scientific term. But the phenomenon of “coinfection” with influenza and the coronavirus is real and, to those in the medical community, not the least bit surprising. A person can be infected with multiple viruses at the same time — or with a virus and some other type of pathogen, such as bacteria or parasites.

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.
