The World Health Organisation currently state that the incubation period is up to 14 days but sometimes it could be longer, even up to 24 days, but typically symptoms show in about 5 days. The current World Health Organisation figures said based on 44,000 patients with the virus, 81% developed mild symptoms, 14% developed severe symptoms and 5% became critically ill. The death rate stated by the World Health Organisation appears to be between 1 and 2% but the current initial figures are obviously unreliable, given that is a currently changing situation. That said WHO say that about 80% of people recover without medical treatment and some people become infected but they do not develop any symptoms or feel unwell. It starts with a fever followed by a dry cough. It then can lead to shortness of breath and some patients require hospital treatment. Other symptoms are a headache, tiredness, nasal congestion, sore throat, diarrhoea and muscle aches. Symptoms often show as mild and begin gradually.If you are in a high risk group with existing medical conditions or the elderly, or if the person develops a fever, cough and breathing difficulties you should seek medical attention by phoning the medical services rather than going to hospitals or medical centres, where there is a risk that you will spread the virus to others.
