The 2022 mpox outbreak in Asia is a part of the ongoing outbreak of human mpox caused by the West African clade of the monkeypox virus. The outbreak was reported in Asia on 20 May 2022 when Israel reported a suspected case of mpox, which was confirmed on 21 May. seven West Asian, three Southeast Asian, three East Asian and one South Asian country, along with Russia, have reported confirmed cases.
a total of 162 cases were confirmed. Most of them were concentrated in the region of West Asia, with 141 of the total 156 cases (≈90.38%) being reported in the region. Israel alone has reported 114 cases (≈73.07%). Israel reported the first community transmission of the disease on 21 June 2022.
A large portion of those infected were believed to have not recently traveled to areas of Africa where mpox is normally found, such as Nigeria, the Democratic Republic of the Congo as well as central and western Africa. It is believed to be transmitted by close contact with sick people, with extra caution for those individuals with lesions on their skin or genitals, along with their bedding and clothing. The CDC has also stated that individuals should avoid contact and consumption of dead animals such as rats, squirrels, monkeys and apes along with wild game or lotions derived from animals in Africa.[1]
In addition to more common symptoms, such as fever, headache, swollen lymph nodes, and rashes or lesions, some patients have also experienced proctitis, an inflammation of the rectum lining. CDC has also warned clinicians to not rule out mpox in patients with sexually transmitted infections since there have been reports of co-infections with syphilis, gonorrhea, chlamydia, and herpes.[2]
According to the World Health Organization, imported cases of mpox from Nigeria was detected in Israel and Singapore in September 2018 and May 2019, respectively.[3]
In 2018, an imported case was detected in Israel. A 38-year-old man came from Rivers State, Nigeria in late September. He showed the symptoms of the disease on that month. Later on October the patient sought medical attention at Shaare-Zedek Medical Center in Jerusalem. He was confirmed to be infected with the West African Clade of monkeypox virus that month. All of the patient's contacts were traced and followed up but no virus transmission were detected.[4]
As the outbreak was spreading in Europe in the middle of May 2022, the Israeli Health Ministry reported a suspected mpox case in the country on 20 May. The case was confirmed by testing on 21 May, becoming the first case in Israel during the outbreak, which also became the first in Asia. The 30-year-old man returned from Western Europe and contracted the disease from there. The ministry reported that he was in isolation in the Ichilov General Hospital in Tel Aviv.[5] [6]
In May and June 2022, two Australians tested positive for mpox in Australia, but before that they stayed in transit in airports for some hours in Southeast Asia.

A study from the Faculty of Medicine, Chulalongkorn University, Thailand led by Dr Dhammika Leshan Wannigama reported Multiple traces of monkeypox virus were detected in non-sewered wastewater with sparse sampling collected from both the Bangkok, Thailand with increasing concentrations from June to August 2022.[9] This is the first dataset related to monkeypox viral DNA in wastewater in Bangkok. Monkeypox viral DNA was first detected in wastewater in the second week of June 2022. From the first week of July, the number of viral DNA copies increased. Sanger sequencing confirmed the identification of the monkeypox virus and its relation to the 2022–2023 mpox outbreak. The same group later released findings from wastewater surveillance in six Southeast Asian countries (Thailand, Lao PDR, Myanmar, Cambodia, Vietnam, and Indonesia), which showed the presence of Monkeypox virus (MPXV) DNA, suggesting local transmission.[10] This information serves as a vital notification for healthcare professionals and aids in the distribution of resources such as testing, vaccines, and treatments in regions with limited resources.
