On Friday, May 20, the World Health Organization has reported that there were 80 cases of monkeypox reported in 12 countries, but has not mentioned which countries those are. However, the National Institute for Communicable Diseases has not reported any cases in South Africa, though there has now been a case reported in Australia.

Update: as of 23 May, the NICD has reported that there are 145 cases in 15 countries, but confirms there are no local cases.

Normally endemic to certain countries where it resides in animal reservoirs, monkeypox is rarely encountered in countries outside those regions. The WHO notes that this is “atypical” for the zoonotic orthopoxvirus, which causes smallpox-like symptoms but with a lower mortality. European public health agencies have so far reported that the UK, Spain, Portugal, Germany, Belgium, France, the Netherlands, Italy and Sweden have seen cases. The first patient in the UK with the virus had returned from a trip to Nigeria, likely catching it there. Cases have been reported in the US and Canada.

The WHO advises that, “As monkeypox spreads through close contact, the response should focus on the people affected and their close contacts. People who closely interact with someone who is infectious are at greater risk for infection: this includes health workers, household members and sexual partners.”

At present, it is unclear why this unusual outbreak is happening now, especially amid the heightened vigilance of the COVID pandemic. One possibility is that some mutation is responsible, though there is little evidence at present to suggest a new variant is responsible.

Another explanation could be that this is simply a matter of the right place and time for the virus. It may also be easier for monkeypox to spread nowadays compared to when there was more widespread use of smallpox vaccine.
