The coronavirus family causes illnesses ranging from the common cold to more severe diseases such as severe acute respiratory syndrome (SARS) and Middle East respiratory syndrome (MERS), according to the WHO.

They circulate in animals and some can be transmitted between animals and humans. Several coronaviruses are circulating in animals that have not yet infected humans.

The new coronavirus, the seventh known to affect humans, has been named COVID-19.

 

The World Health Organization (WHO) has declared the new coronavirus outbreak, which originated in Wuhan, China, a pandemic. 

As of September 20, the global death toll surpassed 957,000 amid more than 30.8 million cases. Over 21 million people have recovered from the disease worldwide, according to the data collected by the Johns Hopkins University in the United States.

Common signs of infection include fever, coughing and breathing difficulties. In severe cases, it can cause pneumonia, multiple organ failure and death.

The incubation period of COVID-19 is thought to be between one and 14 days. It is contagious before symptoms appear, which is why so many people get infected.

Infected patients can be also asymptomatic, meaning they do not display any symptoms despite having the virus in their systems.
