According to the WHO, signs of infection include fever, cough, shortness of breath and breathing difficulties. In more severe cases, it can lead to pneumonia, multiple organ failure, and even death. Current estimates of the incubation period – the amount of time between infection and the onset of symptoms – ranging from one to 14 days. Most infected people show symptoms within five to six days. However, infected patients can also be asymptomatic, meaning they do not display any symptoms despite having the virus in their systems. The elderly, especially those with pre-existing conditions like diabetes, heart disease, and lung disease, may be severely affected by the new virus.
