Monkeypox virus has been found in anal samples from asymptomatic males who have intercourse with men, presenting another another concern about the current viral outbreak: the likelihood of silent infection. The most recent epidemic of the monkeypox virus, which started in May, mostly impacted guys who had intercourse with other men. A recent publication in Annals of Internal Medicine showed three asymptomatic individuals with no cutaneous manifestations but positive findings, despite the fact that most infections are characterised by cutaneous lesions.
The report suggests that vaccination limited to those with known exposure to the monkeypox virus may not be an effective strategy for preventing infection.
“If so, the practice of ring postexposure vaccination around symptomatic persons with probable or confirmed monkeypox virus infection may not be sufficient to contain spread,” the team added.
