The US’ confirmed cases of coronavirus include two patients in California, one in Arizona, one in Washington, and one in Illinois.

The US now has five confirmed cases of a deadly coronavirus that originated in Wuhan, China less than a month ago. The outbreak has killed 81 people and infected more than 2,800 in mainland China.
It has spread to 13 countries: Australia, Cambodia, Canada, France, Japan, Malaysia, Nepal, Singapore, South Korea, Taiwan, Thailand, the US, and Vietnam.
The coronavirus family is a large group of viruses that typically affect the respiratory tract. Coronaviruses can lead to illnesses such as the common cold, pneumonia, and severe acute respiratory syndrome (SARS), which resulted in 8,000 cases and 774 deaths in China from November 2002 to July 2003.
Patients with the new coronavirus — known as 2019-nCoV — have reported symptoms like fever, coughing, and difficulty breathing. Those who have died were elderly or otherwise unwell, according to Chinese officials. No deaths have been reported outside China.
