Arenaviridae is a family of viruses that primarily infect rodents and arenaviruses are zoonotic viruses, meaning they can be transmitted from animals to humans. 🐭 They're known for causing diseases like Lassa fever and lymphocytic choriomeningitis (LCMV). These viruses have a unique appearance under a microscope, with granules resembling grains of sand, which gave them their name. Arenaviruses have a two-part RNA genome, setting them apart from many other RNA viruses. Think of them as the 'grainy' viruses with a rodent connection. Public health surveillance and rodent control are crucial in preventing human infections.
