How does mpox spread?

Mpox spreads through close, sustained physical contact with someone who has mpox, including intimate or sexual contact, hugging, kissing, or touching mpox lesions. It can also spread through respiratory secretions during prolonged face-to-face contact, touching contaminated materials (bedding, towels, clothing), and rarely from pregnant person to fetus.

What does the mpox rash look like?

Mpox rash progresses through stages: flat spots → raised bumps → fluid-filled blisters → pus-filled blisters → scabs. Lesions can be painful and may look like pimples, blisters, or syphilis sores. The 2022 outbreak often showed lesions concentrated on genital/anal areas, mouth, throat, or hands/feet. Rash lasts 2-4 weeks.

Who is at highest risk for mpox?

Higher risk groups include: men who have sex with men (especially those with multiple partners), people with HIV (particularly if CD4 count is low), people who've had close contact with someone with mpox, sex workers, and healthcare workers treating mpox patients without proper PPE.

Is there a vaccine for mpox?

Yes, the JYNNEOS vaccine is FDA-approved for mpox prevention. It's given as 2 doses, 4 weeks apart. The vaccine is recommended for people at high risk of exposure and can be given after known exposure to prevent or reduce severity.

Most people recover without specific treatment with supportive care. For severe cases or immunocompromised people, the antiviral tecovirimat (TPOXX) may be used. Isolation is required until all lesions have healed and new skin has formed (typically 2-4 weeks).

Where are mpox cases occurring now?

After the 2022 global outbreak peak, cases have significantly declined but continue worldwide. The virus remains endemic in parts of Africa where it regularly infects humans through contact with infected animals. Check the live outbreak data above for current mpox activity.

Prevention
