One in five people with the virus get very ill. The illness starts with a temperature. Then a dry cough develops. This causes difficulty breathing and patients may need to go to hospital.

The Chinese government first said humans couldn't pass on the virus. Now, some cities are completely closed in China and they have built new hospitals. People want to stop the disease from spreading. Governments worldwide are stopping people from travelling.

Infected people must stay away from other people. Medical staff have to wear protective clothing. Disease scientists are trying to identify and test people who have come into contact with the virus.
