Coronavirus explained: What is a global public health emergency? What happens now?

The World Health Organisation (WHO) has on Thursday night declared an international public health emergency over the coronavirus outbreak. Health experts made the announcement on Thursday evening following a meeting of the WHO emergency committee in Geneva.

Speaking to reporters, WHO Director-General Dr Tedros Adhanom Ghebreyesus said: “The main reason for this declaration is not because of what is happening in China, but because of what is happening in other countries.

“Our greatest concern is the potential for the virus to spread to countries with weaker health systems, and which are ill-prepared to deal with it.”

Last week, WHO said it was “too early” to declare an international public health emergency but on Thursday said action was needed to help countries to prepare for the possibility of it spreading further.

The new virus has now infected more people in China than fell ill during the 2002-2003 severe acute respiratory syndrome (Sars) outbreak. The number of cases has jumped to 7,711, surpassing the 5,327 people diagnosed with Sars.

What is a global public health emergency?

A Public Health Emergency of International Concern (PHEIC) is a formal declaration by the World Health Organization (WHO) of “an extraordinary event which is determined to constitute a public health risk to other States through the international spread of disease and to potentially require a coordinated international response”.

A PHEIC is declared when a situation arises which is “serious, sudden, unusual or unexpected”, which also “carries implications for public health beyond the affected State’s national border” and “may require immediate international action”.

The WHO director-general said of the organisation’s declaration: “The main reason for this decision is not because of what is happening in China but because of what is happening in other countries.
