First and foremost "DO NOT PANIC". The governing bodies are all trying their best not to spread the disease. The lethality rate of the virus is still lesser than Ebola from Africa so panicking never helps. This also helps in preventing the spread of fear and hysteria which causes collective stress which makes the Coronavirus situation worse.
Wait for you governments announcement about the disease, again never panic. Watch news to get daily updates about your country's status and the status of the disease. There will be instructions given to the people by the government to keep the people safe and sound.
Go to your doctor if you are feeling the symptoms of the virus (flu, cough and shortness of breath) or you have been in contact with someone who came recently from Wuhan or other infected places, immediately go to your doctor or any healthcare personnel as soon as possible, this will help in isolating the infection(if you are tested positive) and will help in making sure that you are not infected.
Spread what you know about the disease. Information dissemination plays a big role in this situation.
Wash your hands, include your arms up to your elbow. Wear mask if there were instruction given by your government.
Watch Dr. Mikes video about the Coronavirus, it helps when you know more.
