👉 Metorhabdovirus, also known as Herpes Simplex Virus 2, is a small RNA virus that causes genital herpes and other sexually transmitted infections (STIs). It was discovered in 1957 by scientists at the University of Michigan. The term "metorhabdovirus" refers to its morphology resembling the shape of a mosquito, which is why it's often referred to as a mosquito-related virus.
