Amid the increasing cases of Monkeypox, AIDS Society of India President Dr Ishwar Gilada on May 21 said that this virus generally spreads in animals but later jumps to humans from animals. "Monkeypox is zoonotic like HIV that initially came as monkey virus called simian immunodeficiency virus. Such viruses spread in animals but jump to humans. In the last 40 years, all infections are virals. Don't have a very potent anti-viral. Virals keep mutating," he said.
