Chinese authorities identified the new coronavirus, which has resulted in hundreds of confirmed cases in China, including cases outside Wuhan, with additional cases being identified in a growing number of countries internationally. The first case in the United States was announced on January 21, 2020. This is an ongoing investigation and information is changing rapidly. visit https://www.cdc.gov/coronavirus/2019-ncov/index.html
People in the United States commonly get infected with human coronaviruses and there are four types that are the most common. These types of coronaviruses can be detected on respiratory virus panels that are commonly performed at many hospitals and clinical laboratories. Sometimes coronaviruses that infect animals can evolve and make people sick and become a new human coronavirus. An example of this is the newly identified COVID-19 first detected in Wujan, China.
