The 2022–2023 mpox outbreak in Portugal is part of the larger outbreak of human mpox caused by the West African clade of the monkeypox virus. Portugal was the third country, outside of the African countries with endemic mpox, to experience an outbreak in 2022.

Background
These paragraphs are an excerpt from Mpox and 2022–2023 mpox outbreak.

Mpox (formerly known as monkeypox)[3] is an infectious viral disease that can occur in humans and some 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 those infected will recover within a few weeks without treatment.[5] The time from exposure to onset of symptoms ranges from five to twenty-one days and symptoms typically last from two to four weeks.[6] Cases may be severe, especially in children, pregnant women or people with suppressed immune systems.[7]

The disease is caused by the monkeypox virus,[lower-alpha 1] a zoonotic virus in the genus Orthopoxvirus. The variola virus, the causative agent of the disease smallpox, is also in this genus.[4] Human-to-human transmission can occur through direct contact with infected skin or body fluids, including sexual contact.[4] People remain infectious from the onset of symptoms until all the lesions have scabbed and healed.[7] It may spread from infected animals by handling infected meat or via bites or scratches.[7] Diagnosis can be confirmed by PCR testing a lesion for the virus' DNA.[4]

An ongoing outbreak of mpox was confirmed on 6 May 2022, beginning with a British resident who, after travelling to Nigeria (where the disease is endemic), presented symptoms consistent with mpox on 29 April 2022. The resident returned to the United Kingdom on 4 May, 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
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

On 18 May 2022, Portugal reported five cases in men[13] and 15 suspected cases.[14] At the end of May, 96 people were confirmed to have mpox,[15] before the amount reached 153 after the first week of June.[16] As of 7 July, there were 433 confirmed cases in the country.[2]

Notes
  1. The World Health Organization (the authority on disease names) announced the new name "mpox" in November 2022. But virus naming is the responsibility of the International Committee on the Taxonomy of Viruses (ICTV), which is currently reviewing all orthopoxvirus species. As of March 2023, the official name of the virus remains "monkeypox virus".[3]
