It is worth noting that the "public health emergency of international concern" identified by World Health Organization (WHO) is the highest level of health alert. since 2005, there have been a total of six public health emergencies of international concern, namely: H1N1 influenza pandemic in 2009, polio epidemic in 2014, Ebola epidemic in West Africa in 2014, Zika virus epidemic from 2015 to 2016, and Congo Ebola epidemic from 2018 to 2019. And the global COVID-19 epidemic announced on January 31, 2020.

Confirmed cases have been found in the other 44 states and the capital Washington.

In addition, monkeypox virus is also fatal. Since the first death of monkeypox virus was reported on June 27, there have been five deaths.

British scientists estimate that the size of the monkeypox epidemic has doubled about every two weeks. They say that in nearly 80 per cent of cases, there is no information about whether the patient has been in contact with confirmed cases, meaning the virus is spreading undetected.

Monkeypox is a zoonotic disease found in laboratory animals monkeys in 1958. It was first found in humans in 1970, mainly in rainforest countries in central and western Africa.

Yu Dongzheng, head of the Institute of Infectious Diseases at the Chinese Center for Disease Control and Prevention, said in an interview with the Global Times that monkeypox got its name because it was first found in monkeys, but that doesn't mean monkeypox virus is found only in monkeys. In fact, there are many natural hosts of monkeypox, such as squirrels, marmots, rabbits and other rodents.
