You can find information and guidance from WHO regarding the current outbreak of novel coronavirus (2019-nCoV) that was first reported from Wuhan, China, on 31 December 2019:

1. Washing your hands frequently with an alcohol-based hand rub or soap and water kills the virus if it is on your hands.
2. Maintain social distancing – maintain at least 1 metre (3 feet) distance between yourself and other people, particularly those who are coughing, sneezing and have a fever. When someone who is infected with a respiratory disease, like 2019-nCoV, coughs or sneezes they project small droplets containing the virus. If you are too close, you can breathe in the virus
3. Avoid touching eyes, nose and mouth. Hands touch many surfaces which can be contaminated with the virus. If you touch your eyes, nose or mouth with your contaminated hands, you can transfer the virus from the surface to yourself.
4. If you have fever, cough and difficulty breathing, seek medical care early. Tell your health care provider if you have travelled in an area in China where 2019-nCoV has been reported, or if you have been in close contact with someone with who has travelled from China and has respiratory symptoms.
5. If you have mild respiratory symptoms and no travel history to or within China, carefully practice basic respiratory and hand hygiene and stay home until you are recovered, if possible.
6. As a general precaution, practice general hygiene measures when visiting live animal markets, wet markets or animal product markets. Ensure regular hand washing with soap and potable water after touching animals and animal products; avoid touching eyes, nose or mouth with hands; and avoid contact with sick animals or spoiled animal products. Strictly avoid any contact with other animals in the market (e.g., stray cats and dogs, rodents, birds, bats). Avoid contact with potentially contaminated animal waste or fluids on the soil or structures of shops and market facilities
7. Avoid consumption of raw or undercooked animal products. Handle raw meat, milk or animal organs with care, to avoid cross-contamination with uncooked foods, as per good food safety practices.
