corona-virus is a kind of common virus that causes an infection in nose, sinuses or upper throat. Most coronaviruses are not dangerous. Some types of coronaviruses are serious, though. About 858 people have died from Middle East respiratory syndrome (MERS), which first appeared in 2012 in Saudi Arabia and then in other countries in the Middle East, Africa, Asia, and Europe. In April 2014, the first American was hospitalized for MERS in Indiana and another case was reported in Florida. Both had just returned from Saudi Arabia. In May 2015, there was an outbreak of MERS in Korea, which was the largest outbreak outside of the Arabian Peninsula. In 2003, 774 people died from a severe acute respiratory syndrome (SARS) outbreak. As of 2015, there were no further reports of cases of SARS. But In early 2020, following a December 2019 outbreak in China, the World Health Organization identified a new type, 2019 novel coronavirus (2019-nCoV).Often a coronavirus causes upper respiratory infection symptoms like a stuffy nose, cough, and sore throat. The coronavirus can also cause middle ear infections in children. There is no specific treatment for the virus. Patients are generally given supportive care for their symptoms, such a fluids and pain relievers. Hospitalized patients may need support with breathing.
