The Origin Of Norovirus
Norovirus was first described by Zahorsky as ‘winter vomiting diseases’.
Norovirus was not confirmed until 1972, when the virus’s particles were first
seen through the electron microscope (EM). The first outbreak of norovirus was
in 1968 at a school in Norwalk, Ohio, with a great rate of illness to the
students and teachers. Since the 1970s, Norovirus was known as ‘Norwalk-like
virus’ and ‘small round structure virus’ named after the location where the
virus was found or by the physical appearance on the EM.
