The 2022–2023 mpox outbreak in Chile is a part of the outbreak of human mpox caused by the West African clade of the monkeypox virus. The outbreak reached Chile on 17 June 2022.[2]

Background

[edit]
These paragraphs are an excerpt from Mpox and 2022–2023 mpox outbreak.
Mpox (/ˈɛmpɒks/, EM-poks; formerly known as monkeypox)[3] is an infectious viral disease that can occur in humans and other animals.[4] Symptoms include a rash that forms blisters and then crusts over, fever, and swollen lymph nodes.[4] The illness is usually mild, and most of infected individuals recover within a few weeks without treatment.[5] The time from exposure to the onset of symptoms ranges from five to twenty-one days, and symptoms typically last from two to four weeks.[6] However, cases may be severe, especially in children, pregnant women, or people with suppressed immune systems.[7]

An ongoing outbreak of mpox was confirmed on May 6, 2022, beginning with a British resident who, after travelling to Nigeria (where the disease is endemic), presented symptoms consistent with mpox on April 29, 2022. The resident returned to the United Kingdom on May 4, creating the country's index case of the outbreak.[8] The origin of several of the cases of mpox in the United Kingdom is unknown. Some monitors saw community transmission taking place in the London area as of mid-May,[9] but it has been suggested that cases were already spreading in Europe in the previous months.[10]

Transmission

[edit]
Stages of lesion development.

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.[11]

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.[12]

History

[edit]

The first case of infection was recorded on June 17 in Santiago de Chile after an adult with a history of travel to Europe presented symptoms
