The WHO on Saturday, 23 July, declared Monkeypox a global threat to public health. Here are some of the reasons why the WHO chief Dr Tedros Adhanom Ghebreyesus declared it a public health emergency: It spread rapidly to at least 75 nations and territories More than 16,000 cases of the virus have been found only this year in countries that were endemic to the disease Criteria for declaring it a public health emergency of international concern have been met The number of cases has grown five-fold in the last three weeks, and more about the virus is yet to be known There are many unknowns about the virus. It needs global coordination to understand more about its transmissibility, spread, vaccines, and severity The disease can be counted as a risk to human health, with the potential to interfere with the international movement of people.
