What is a coronavirus?

Coronaviruses are a large family of viruses that cause diseases ranging from the common cold to more serious diseases, such as severe acute respiratory syndrome (SARS) and the Middle East respiratory syndrome (MERS), according to the World Health Organization ( WHO).

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

The new coronavirus has been named new coronavirus (2019-nCoV). It is the seventh coronavirus that is known to affect humans.

What are the symptoms?

Common signs of infection include fever, cough and shortness of breath.

In more severe cases, the infection can cause pneumonia, SARS, kidney failure and death.

It is believed that the incubation period of the new coronavirus is between one and 14 days. The virus is contagious before symptoms appear.

What we know so far about the coronavirus

What is happening in China now?
Efforts to contain the outbreak have caused a major disruption in China, with almost 20 cities facing travel restrictions, affecting at least 56 million people. Detection stations have been established in bus terminals, trains and airplanes throughout the country.

China has banned wildlife trade and extended Lunar New Year vacations until February 2 to prevent transmission from accelerating when people return from vacation.

The United States, Japan and several European countries are working to evacuate their citizens from Wuhan and the wider province of Hubei in some cases.

Should I be worry? And how can I protect myself?
WHO has recognized that the virus is an emergency in China, but said on January 23 that it was too early to declare it a public health emergency of international interest.

Tedros Adhanom Ghebreyesus, the head of the agency, traveled to Beijing to meet with government and health officials.

People are urged to follow local security measures.

WHO recommends basic hand hygiene, such as washing your hands with soap and water, and making sure to cover your mouth with your elbow when you sneeze or cough.

Avoid unnecessary and unprotected contact with animals and be sure to wash your hands well after contact.

Make sure the meat consumed is well cooked.
