Mpox and HIV: A Growing Concern for Men Who Have Sex with Men
Recent data from Hangzhou, China, reveals a concerning trend: mpox (formerly known as monkeypox) is significantly more severe in men who have sex with men (MSM) too living with HIV. A retrospective study of 104 confirmed mpox cases highlighted a clear link between coinfection and increased hospitalization rates, with all 27 hospitalizations occurring in individuals with both mpox and HIV.
The Severity of Coinfection
The study, published in AIDS Behavior, found that individuals with mpox-HIV coinfection experienced a greater symptom burden. Specifically, lesion pain was reported in 67.39% of coinfected patients, compared to just 39.66% of those with mpox alone. This suggests that the presence of HIV exacerbates the discomfort and clinical presentation of mpox.
Immune Suppression as a Key Factor
Even among coinfected individuals receiving antiretroviral therapy (ART) – 97.83% of the study cohort – a substantial proportion (28.26%) had low CD4+ T-cell counts (≤350 cells/µL). Lower CD4 counts were directly correlated with more severe mpox manifestations and a higher likelihood of hospitalization. This underscores the importance of immune function in managing mpox, particularly in those with underlying HIV infection.
Risky Behaviors and Prevention Strategies
The research also pointed to behavioral factors contributing to coinfection risk. High-risk sexual behaviors, including multiple partners and frequent sexual activity, were associated with both mpox and HIV. These findings emphasize the need for integrated prevention strategies targeting these behaviors within high-risk groups.
Implications for Healthcare Providers
These findings have important implications for clinicians in the United States and globally. Documenting HIV status and recent CD4 counts is crucial when evaluating patients with suspected mpox. Careful assessment of pain levels and lesion distribution can also aid in identifying those at higher risk of severe outcomes. The study reinforces that mpox, whereas often self-limiting, can be significantly more dangerous in individuals with compromised immune systems.
The study also highlights the need for coordinated public health strategies that address both HIV and mpox in overlapping populations. This includes targeted vaccination campaigns, increased access to HIV testing and treatment, and education on safer sexual practices.
Future Trends and Research
As mpox continues to evolve, ongoing surveillance is critical. Researchers are working to understand the long-term effects of mpox-HIV coinfection and to identify predictors of vaccine response in this population. Further investigation is needed to determine the optimal strategies for managing mpox in individuals with varying degrees of immune suppression.
The retrospective nature of the Hangzhou study means it can identify associations, but not definitively prove cause-and-effect. Larger, prospective studies are needed to confirm these findings and to explore the underlying mechanisms driving the increased severity of mpox in people with HIV.

FAQ
Q: Is mpox a sexually transmitted infection?
A: While mpox can be spread through sexual contact, it is not exclusively a sexually transmitted infection. It can also spread through close contact with lesions, respiratory droplets, and contaminated surfaces.
Q: What are the symptoms of mpox?
A: Common symptoms include fever, headache, muscle aches, swollen lymph nodes, and a rash that can look like pimples or blisters.
Q: Is there a vaccine for mpox?
A: Yes, the JYNNEOS vaccine is available for individuals at high risk of mpox exposure.
Q: How can I reduce my risk of mpox?
A: Practice safer sex, avoid close contact with individuals who have symptoms, and gain vaccinated if eligible.
Pro Tip: If you suspect you have mpox, contact your healthcare provider immediately for testing and guidance.
