Monkeypox Outbreak 2022


August 19, 2022

The 2022 monkeypox outbreak is a near-worldwide outbreak of monkeypox.


The initial cluster of cases was seen in the UK, initially on 6 May 2022 in a person with travel connections to Nigeria, where the disease is endemic. The outbreak marks the first event in a spread of monkeypox far beyond central and western Africa. From May 18, cases were reported from more and more countries and regions, mainly in Europe, but also in North and South America, Asia, Africa and Oceania. On July 23, the World Health Organization (WHO) declared the outbreak a public health emergency of international concern (PHEIC) and upgraded the outbreak to a global health emergency status. As of July 30, there were a total of 22,763 confirmed cases. At the end of July 2022, the first European deaths linked to monkeypox were recorded in Spain. Two young men were affected. At that time, there were 4,200 confirmed cases in Spain alone. On July 30, 2022, the governor of the US state of New York declared a state of emergency because of the spread of monkeypox Half of July 2022 was also detected in two male adolescents in Germany for the first time. At that time, according to the Robert Koch Institute, 2,724 infections had been reported from all federal states, almost exclusively men. On August 2, 2022, California became the third US state to declare a state of emergency because of the spreading monkeypox after 827 cases had become known there. A short time later, the US government declared a national health emergency. According to the Ministry of Health, more than 6,600 cases have already been confirmed.

Transmission and Outbreak Affected

Monkeypox is spread from person to person primarily through close physical contact, including close contact during sexual activity, regardless of the sex of those involved. However, they are not classified as a sexually transmitted disease because they do not require contact with genital fluids to spread. Transmission can also occur through contaminated objects that have been used or touched by infected people. According to a study published on July 21, 2022 by US medical experts, 95% of the cases reported from April to June 2022 outside of the endemic regions in Africa were related to sexual contacts; 98% of reported cases outside of endemic regions in Africa have occurred in men who have had same-sex intercourse. In particular, people with several sexual partners were affected. With a view to the transmission routes, experts see no reason to worry about a pandemic spread, especially since the virus would not be spread by droplet infection. The Professional Association of Pediatricians (BVKJ) emphasizes that the virus is “far less contagious than Corona”.
