Coronavirus explained: Why is it called coronavirus? What does corona mean?

Coronavirus is triggering concern around the globe with countries restricting travel to China – where the disease first broke out. Now the World Health Organisation has warned “the whole world needs to be on alert” as their emergency committee prepares for a meeting on Thursday.

The death toll in China passed 130 and cases of human-to-human transmission were confirmed in at least three other countries.

Dr Michael Ryan, executive director at the WHO Health Emergencies Programme, said the decision to reconvene was due to the increasing number of cases and evidence of person-to-person transmission of the virus.

He told a press conference in Geneva that the Chinese government deserves “huge credit” for its response and transparency regarding the “extraordinary challenge”.

He said: “The whole world needs to be on alert now, the whole world needs to take action and be ready for any cases that come, either from the original epicentre or from other epicentres that become established.”

The WHO said person-to-person transmission had been confirmed in three countries outside China – Japan, Vietnam and Germany.

Director-general Tedros Adhanom Ghebreyesus told the conference: “The continued increase in cases and the evidence of human-to-human transmission outside China are, of course, most deeply concerning.

“Although the numbers outside China are relatively small, they hold the potential for a much larger outbreak.”

He added that China “deserves our gratitude and respect” for its “extraordinary” efforts to prevent the spread of cases outside the country.

Coronavirus has a series of crown-like spikes on its surface, which is the reason for the name.

Other well-known coronaviruses include severe acute respiratory syndrome (SARS) and Middle East respiratory syndrome (MERS).

The first SARS outbreak came in China between November 2002 and July 2003 which triggered 8,098 cases, resulting in 774 deaths reported in 17 countries.

MERS was first reported in Saudi Arabia in 2012 and has since spread to several other countries, including the United States.

Most people infected with MERS-CoV developed severe respiratory illness, including fever, cough, and shortness of breath. Many of them have died.

Dr Mike Ryan, head of WHO health emergencies programmes, said China had “a laser focus” on stopping the coronavirus outbreak.

He said: “We are at an important juncture in this event. We believe these chains of transmission can still be interrupted.

Referring to China he continued: “They are taking extraordinary measures in the face of what is an extraordinary challenge.”

The coronavirus has remained “remarkably stable”, according to Dr Ryan, a veteran of outbreaks including the SARS epidemic as well as Ebola outbreaks in West Africa.
