What caused Covid 19?


Answer: The novel virus was first identified in an outbreak in the Chinese city of Wuhan in December 2019. Attempts to contain it there failed, allowing the virus to spread to other areas of Asia and later worldwide. The World Health Organization (WHO) declared the outbreak a public health emergency of international concern on 30 January 2020, and a pandemic on 11 March 2020. As of 10 March 2023, the pandemic had caused more than 676 million cases and 6.88 million confirmed deaths, making it one of the deadliest in history.
