What is mpox?

Mpox is a viral infection. Anyone can acquire it through relevant contact; a person's identity does not cause infection.

How does it spread?

Through close contact, including skin contact, kissing and sex; contaminated towels or bedding can also transmit it. It is not exclusively sexually transmitted.

What symptoms should I notice?

Painful or itchy lesions, sometimes just one, including around the genitals, anus or mouth. Fever and swollen lymph nodes can occur.

When do symptoms appear?

Usually after 6–13 days, sometimes up to 21 days after infection. This incubation period is not a window for a reliable negative test.

How is it tested?

A clinician assesses the rash and arranges PCR using lesion material. Do not diagnose from a photograph or collect a sample yourself.

When is urgent assessment needed?

Seek immediate medical help for eye involvement, difficulty breathing or swallowing, severe pain, or inability to drink fluids.

Who needs early medical care?

Pregnant people, children and people with weakened immunity, including advanced untreated HIV, face a higher risk of complications.

How long can it spread?

Until every scab has fallen off and healthy new skin has formed underneath. A resolved fever alone does not mean infectiousness has ended.

How can I reduce transmission?

Avoid close and sexual contact while awaiting assessment. Do not share towels; follow clinical advice on isolation and notifying close contacts.

Vaccination and the next step

After exposure, ask a clinician promptly about vaccination. Eligibility and access depend on local guidance. Ask a clinician where to obtain assessment and testing before visiting.

Does the rash always cover the body?

No. There may be only a few lesions, without a widespread rash or preceding fever.

Should I wait for symptoms after known exposure?

Do not delay contacting a clinician: prevention after exposure is time-sensitive.
