On March 1 1 day, 2020, the Director-General of WHO, Tedros Adhanom Ghebreyesus, said that the COVID-19 epidemic had become an epidemic.
Tedros Adhanom Ghebreyesus said at a regular news conference that the spread and severity of the epidemic are deeply worrying. "Therefore, we think that the epidemic situation in COVID-19 has epidemic characteristics."
He said: "We have never seen an epidemic caused by coronavirus before. We have never seen a controlled epidemic before. "
He stressed that describing the novel coronavirus epidemic as an "epidemic" will not change WHO's assessment of its threat, "what WHO is doing, and what countries should do".
Novel coronavirus is in the early stage of rapid change. China has published the complete genome sequence of novel coronavirus that caused novel coronavirus, which will help scientists and public health organizations all over the world to participate in the research and development of diagnostic reagents and the study of virus pathogenicity.
