Are people with HIV at greater risk from mpox?

Céline Gounder, MD, Infectious Disease Specialist answers questions about the mpox virus.

If you have HIV and AIDS and your immune system is weak with a CD four count, especially below 200, you are at risk for more severe complications of monkeypox.

We strongly recommend that you see an HIV care provider and start antiretroviral therapy. That will be the best way to protect you against the consequences of HIV and AIDS, including developing severe forms of monkeypox.

There are experimental treatments for monkeypox that we may use if somebody develops a severe case of monkeypox disease or if they're at very high risk for severe disease.
