While they might look like dust under a lens, are a family of serious pathogens that primarily live in rodents but can jump to humans with devastating effects. What exactly are they? Arenaviruses are "enveloped" RNA viruses, meaning they are
Arenaviruses: The "Sandy" Pathogens You Need to Know When scientists first looked at these viruses under an electron microscope, they saw what looked like tiny grains of sand scattered inside the viral particles. This unique appearance gave them their name—derived from the Latin arena , meaning "sandy". How do they spread
