ABSTRACT
Introduction
Monkeypox virus is a zoonotic double-stranded DNA poxvirus in the genus Orthopoxvirus, family Poxviridae. Until recently, monkeypox was found primarily in Central and West Africa, where the virus had split into Congo Basin and West African clades.
Areas Covered
On 6 May 2022, monkeypox was detected in the United Kingdom and the virus has now been detected in every continent except Antarctica. The current outbreak represents the first documentation of widespread community transmission outside of Africa.
Expert Opinion
On 23 July 2022, the World Health Organization declared monkeypox a public health emergency of international concern and issued a series of guidance and recommendations for governments, health professionals and the public. This manuscript reviews what is known about monkeypox virus, with a focus on recent diagnostics and epidemiologic advances, and explores how recent advances in our understanding of the virus will be used to combat the expanding outbreak.
Article highlights
The first case of monkeypox in humans was detected in 1970 in the Democratic Republic of the Congo.
Monkeypox is often mistaken for other viral infections, including varicella, variola, and measles
Monkeypox symptoms range from systemic illness (fever, headache, myalgias, lethargy) to a maculopapular rash that may initially appear as pimples or blisters on the face, oral or genital mucosa, or the hands, feet, and chest, and may evolve into vesicles that eventually scab.
Testing capacity for monkeypox is rapidly expanding; the preferred method of diagnosis involves nucleic acid amplification from a direct specimen.
Processing and testing of monkeypox specimens should be performed in facilities that have recently vaccinated personnel, preferably within the past three years.
