Human Infection with the Monkeypox Virus in 16 Different Countries from April to June 2022

Monkeypox

 Since May, the virus has spread quickly throughout the world, mostly among men who have sex with males, raising concerns that homosexual men would once again endure the stigma experienced during the AIDS pandemic.

 BACKGROUND

Prior to April 2022, cases of the monkeypox virus infecting people outside of Africa's endemic regions were infrequent. Cases are currently happening everywhere. Infection outcomes, risk factors, clinical presentation, and transmission are all poorly understood.

METHODS

 To characterise the presentation, clinical course, and consequences of monkeypox virus infections that were verified by polymerase-chain reaction, we assembled a global collaborative group of clinicians. They contributed to an international case series.

RESULTS 

We report 528 illnesses identified at 43 sites across 16 countries between April 27 and June 24, 2022. Overall, 41% of the infected people had a human immunodeficiency virus infection, 75% of them were White, and 98% of the infected people were gay or bisexual men. The median age was 38 years. In 95% of the infected individuals, sexual activity was thought to be the mode of transmission. In this case series, 95% of the participants had a rash, 73% had anogenital lesions, and 41% had mucosal lesions. 64% of the participants had more than 10 lesions (with 54 having a single genital lesion). Fever (62%), fatigue (41%), headache (27%), and myalgia (31%), together with lymphadenopathy (56%), were typical systemic symptoms that preceded the rash. Of the 377 people who were tested, 109 (or 29%) reported concurrent sexually transmitted infections. The median incubation period among the 23 individuals with a clear exposure history was 7 days (range, 3 to 20). Of the 32 individuals whose seminal fluid was examined, DNA from the monkeypox virus was found in 29 of them. In total, 5% of the individuals received antiviral treatment, and 70 (13%) of those individuals were hospitalised for reasons including pain management, mostly for severe anorectal pain (21 people), soft tissue superinfection (18), pharyngitis limiting oral intake (5), eye lesions (2), acute kidney injury (2), myocarditis (2), and infection-control purposes (13). No fatalities were noted.

CONCLUSIONS

Monkeypox appeared in this case series as a variety of dermatologic and systemic clinical symptoms. The concurrent discovery of cases outside of regions where monkeypox has historically been endemic emphasises the necessity of early detection and diagnosis of cases in order to stop further community spread.
