Who is most at risk?

You are at risk if you have close contact with someone who has mpox (for example, you live with the person or have sexual contact with them). You may be at a higher risk of getting very sick if:

• You have a weak immune system.
• You are under age 18 years.
• You are pregnant.

Symptoms

Most people with mpox infection will get a rash or sores which can be on their hands, feet, mouth, and genitals. The rash can last 14 to 28 days.

Early symptoms may include:

• fever
• chills
• swollen lymph nodes
• headache
• muscle pain
• joint pain
• back pain
• exhaustion (feeling very tired)

You can spread mpox to others from the time your symptoms start until the rash goes away and your skin heals.

Most people can treat their symptoms at home.
