Zika virus is also related to dengue, Japanese encephalitis, yellow fever, and viruses at West Nile. During 1950s, it was widely prevalent in the equatorial belt from Africa to Asia and then it started spreading eastward across the Pacific Ocean and then to French Polynesia. It has reached pandemic levels in other countries.
