The Geneva-based agency, which declared the H1N1 swine flu outbreak a pandemic in 2009, declared the novel coronavirus that emerged in Wuhan, China in December a public health emergency of International concern, known as a PHEIC, on Jan. 30."There is no official category (for a pandemic)," WHO spokesman Tarik Jasarevic said. "WHO does not use the old phasing system that some people may be familiar with from 2009. Under the IHR (International Health Regulations), WHO has declared a public health emergency of international concern."
