New York City’s Health Department is looking into two more cases of people who may possibly have novel coronavirus.

They are the fourth and fifth people in New York City to meet the criteria to have samples sent to the Centers for Disease Control and Prevention.

They each had recently been in China and “presented with fever and cough or shortness of breath without another common cause, like influenza and other respiratory viruses, identified through testing,” according to the Health Department.

According to a Health Department release:

It says there are now 11 confirmed cases in the United States and over 20,000 worldwide.

According to the Health Department, the novel (new) coronavirus is a strain of coronavirus that has not been previously detected in humans. This novel coronavirus can lead to symptoms of fever, cough or shortness of breath. While some infections have resulted in severe illness, and even death, others have presented with milder symptoms and been discharged from care.
