On August 5, 2022, this report was posted as an MMWR Early Release on the MMWR website (https://www.cdc.gov/mmwr).Monkeypox virus, an orthopoxvirus sharing clinical features with smallpox virus, is endemic in several countries in Central and West Africa. The last reported outbreak in the United States, in 2003, was linked to contact with infected prairie dogs that had been housed or transported with African rodents imported from Ghana (1). Since May 2022, the World Health Organization (WHO) has reported a multinational outbreak of monkeypox centered in Europe and North America, with approximately 25,000 cases reported worldwide; the current outbreak is disproportionately affecting gay, bisexual, and other men who have sex with men (MSM) (2). Monkeypox was declared a public health emergency in the United States on August 4, 2022. † Available summary surveillance data from the European Union, England, and the United States indicate that among MSM patients with monkeypox for whom HIV status is known, 28%-51% have HIV infection (3-10). Treatment of monkeypox with tecovirimat as a first-line agent is available through CDC for compassionate use through an investigational drug protocol. No identified drug interactions would preclude coadministration of tecovirimat with antiretroviral therapy (ART) for HIV infection. Pre-and postexposure prophylaxis can be considered with JYNNEOS vaccine, if indicated. Although data are limited for monkeypox in patients with HIV, prompt diagnosis, treatment, and prevention might reduce the risk for adverse outcomes and limit monkeypox spread. Prevention and treatment considerations will be updated as more information becomes available.
BackgroundSigns and Symptoms: Classically, monkeypox occurs in three stages. After an incubation period of approximately 1-2 weeks, a prodrome, characterized by fever and lymphadenopathy occurs, which is followed by the onset of a deep-seated vesicular or pustular rash that often begins centrally and spreads to the limbs (11). Transmission of monkeypox can occur through direct contact with the infectious rash, scabs, or body fluids, through respiratory secretions during prolonged face-to-face contact or intimate physical contact, or through touching items, such as clothing or linens, that previously touched a patient's infectious rash or body fluids. § * These authors contributed equally to this report. † h t t p s : / / w w w. w a s h i n g t o n p o s t . c o m / h e a l t h / 2 0 2 2 / 0 8 / 0 4 / monkeypox-public-health-emergency-united-states-becerra/ § https://www.cdc.gov/poxvirus/monkeypox/transmission.html
