Hantavirus came about in March 2020.

The Centres for Disease Control and Prevention refutes the claim by stating that the Hantavirus was first detected in 1993.

In May 1993, an outbreak of an unexplained pulmonary illness occurred in the southwestern United States; in an area shared by Arizona, New Mexico, Colorado and Utah known as 'The Four Corners'. The physicians and other scientific experts worked intensively to narrow down the list of possible causes and were able to link the pulmonary syndrome with a virus, know as Hantavirus caused by rodents.

Other early cases of Hantavirus have been discovered by examining samples of tissue belonging to people who had died of unexplained adult respiratory distress syndrome. The earliest known case of Hantavirus that has been confirmed has been the case of a 38-year-old Utah man in 1959.

The COVID-19 pandemic has given rise to a lot of potentially dangerous misinformation. For reliable advice on COVID-19 including symptoms, prevention and available treatment, please refer to the World Health Organisation or your national healthcare authority.
