Monkeypox

Conteúdo atualizado em: 26/06/2022

"Monkeypox is a viral zoonosis (a virus transmitted to humans from animals) with symptoms similar to those seen in the past in smallpox patients, although it is clinically less severe. With the eradication of smallpox in 1980 and subsequent cessation of smallpox vaccination, monkeypox has emerged as the most important orthopoxvirus for public health. Monkeypox primarily occurs in central and west Africa, often in proximity to tropical rainforests, and has been increasingly appearing in urban areas. Animal hosts include a range of rodents and non-human primates." (WHO)

Outbreak and control

"In May 2022, multiple cases of monkeypox were identified in several non-endemic countries. Studies are currently underway to further understand the epidemiology, sources of infection, and transmission patterns." (WHO)

Transmission

"Animal-to-human (zoonotic) transmission can occur from direct contact with the blood, bodily fluids, or cutaneous or mucosal lesions of infected animals (…) Human-to-human transmission can result from close contact with respiratory secretions, skin lesions of an infected person or recently contaminated objects." (WHO)

Diagnosis

"Monkeypox presents with fever, an extensive characteristic rash and usually swollen lymph nodes. It is important to distinguish monkeypox from other illnesses such as chickenpox, measles, bacterial skin infections, scabies, syphilis and medication-associated allergies. The incubation period of monkeypox can range from 5 to 21 days."    (WHO)

Therapeutics
