Coronaviruses are a large group of viruses that are known to infect both humans and animals, and in humans causes respiratory illness that range from common colds to much more serious infections. The most well-known case of a coronavirus epidemic was Severe Acute Respiratory Syndrome (Sars), which, after first being detected in southern China in 2002, went on to affect 26 countries and resulted in more than 8,000 cases.
Outbreak of respiratory illness caused by a novel coronavirus that was first detected in Wuhan City, Hubei Province, China and which continues to expand. Chinese health officials have reported thousands of infections, with the virus reportedly spreading from person-to-person in many parts of that country. Infections with 2019-nCoV, most of them associated with travel from Wuhan.
The virus appears to have originated from a Wuhan seafood market where wild animals, including marmots, birds, rabbits, bats and snakes, are traded illegally. Coronaviruses are known to jump from animals to humans, so it’s thought that the first people infected with the disease – a group primarily made up of stallholders from the seafood market – contracted it from contact with animals.
Although an initial analysis of the virus suggested it was similar to coronavirus seen in snakes, it now seems more likely that it came from bats.
170 people have died. More than 7,711 cases have been confirmed. Thirty-eight more deaths in China from the coronavirus were announced on Thursday, bringing the toll to 170. Most of those recent deaths, 37, occurred in Hubei Province, the center of the outbreak.
