GENEVA, Aug 25 (AFP) - Monkeypox cases fell by a fifth last week as infections in Europe dropped but the outbreak is going through "intense transmission" in the Americas, the World Health Organization said on Thursday (Aug 25).

The WHO sounded the alarm for Latin America in particular, pointing to a lack of awareness and public health measures to control the spread of the virus.

A surge in monkeypox infections has been reported since early May outside the African countries where it has long been endemic.

The WHO triggered its highest level of alarm on Jul 24, classifying it as a public health emergency of international concern, alongside COVID-19.

There have been 45,355 cases and 15 deaths this year, across at least 96 countries, according to the WHO's dashboard.

After four consecutive weeks of increase, the number of monkeypox cases newly reported dropped by 21 per cent last week compared to the previous seven days, from 5,907 to 5,213.

"In the early stages of the outbreak, most reported cases were in Europe, with a smaller proportion in the Americas," WHO chief Tedros Adhanom Ghebreyesus told a press conference.

"That has now reversed, with less than 40 per cent of reported cases in Europe and 60 per cent in the Americas," which is going through a steep rise, he said.

"There are signs that the outbreak is slowing in Europe, where a combination of effective public health measures, behaviour change and vaccination are helping to prevent transmission.

"However, in Latin America in particular, insufficient awareness or public health measures are combining with a lack of access to vaccines to fan the flames of the outbreak."
