The World Health Organization declared that mpox no longer constitutes a global health emergency on Thursday, almost exactly a year after the disease formerly known as monkeypox started spreading globally.
WHO chief Tedros Adhanom Ghebreyesus said the decision was prompted by sharply falling case numbers worldwide, but emphasised that the disease remains a threat, particularly in areas of Africa where it has long been endemic.
The announcement comes a week after the UN agency also declared that Covid-19 no longer constitutes a public health emergency of international concern (PHEIC), its highest level of alarm.
“However, as with Covid-19, that does not mean that the work is over,” Tedros told an online press conference.
“While the emergencies of mpox and Covid-19 are both over, the threat of resurgent waves remains for both. Both viruses continue to circulate and both continue to kill,” he added.
Though some countries in Central and West Africa have suffered local outbreaks for decades, in May last year mpox cases started emerging in Europe, North America then elsewhere, mostly among men who have sex with men.
The WHO declared mpox was a PHEIC in July. The number of people infected with the disease — which causes fever, muscular aches and large boil-like skin lesions — has consistently fallen since.
More than 87,000 cases and 140 deaths have been reported from 111 countries during the global outbreak, according to a WHO count.
The countries with the most cases during the global outbreak have been the United States, Brazil, Spain, France, Colombia, Mexico, Peru and the UK, according to the count.
Steady progress
Almost 90 percent fewer cases were recorded over the last three months compared to the previous three-month period, Tedros said.
“We now see steady progress in controlling the outbreak based on the lessons of HIV and working closely with the most affected communities,” Tedros said.
Because the global cases were overwhelmingly among men who have sex with men, there were fears that discrimination would mar the response to the outbreak.
“While stigma has been a driving concern in managing this epidemic and continues to hamper access to care for mpox, the feared backlash against the most affected communities has largely not materialized,” Tedros said.
“For that, we are thankful.” For non-endemic countries, infections spread by travelers represent an ongoing threat, Tedros said, calling on countries to maintain surveillance of the disease and access to tests and vaccines.
People who have untreated HIV are at particular risk of severe forms of mpox, he added.
“While we welcome the downward trend of mpox cases globally, the virus continues to affect communities in all regions, including in Africa, where transmission is still not well understood,” Tedros said.
Mpox continues in Africa
The monkeypox virus — which causes mpox disease — was first discovered in humans in the Democratic Republic of Congo in 1970.
Until a year ago, its spread among humans had been mainly limited to certain West and Central African nations, where local outbreaks are thought to be caused by the virus jumping over to humans from small animals.
Rosamund Lewis, the WHO’s technical lead on monkeypox, said these countries “were dealing with mpox long before this outbreak began and will continue dealing with it for some time to come”.
WHO emergencies director Mike Ryan said he was “shocked” that little international funding had been donated for the fight against mpox in the African countries where it is endemic.
“Maybe it’s an issue of the continued prejudices that exist in this world,” he said. The virus is transmitted through close contact with infected humans or animals, as well as via materials such as contaminated sheets.
After the emergency status was lifted for Covid and mpox, there is now just one WHO-declared PHEIC — for poliovirus, which was declared in May 2014.
