Is there any group of people that are responsible for this virus?

A single group of people are NOT responsible for the virus (called SARS-CoV-2) that causes COVID-19. SARS-CoV-2 is the seventh coronavirus known to infect humans and similar to many other infectious diseases in humans, the SARS-CoV-2 virus likely started in animals and then infected humans.

Epidemiologists and other medical experts believe SARS-CoV-2 originated in a “wet market”, which is a market that sells live and dead animals that people purchase to eat. Despite likely starting in a “wet market”, the virus’ main mode of transmission is now person-to-person.
