How long is someone with mpox contagious?

A person with mpox is contagious to others from the moment symptoms begin to appear until the rash has healed completely, all scabs have fallen off, and a fresh layer of skin has formed. This process typically takes two to four weeks [1].

It is very important to understand this period to ensure appropriate preventive measures are taken and to prevent the spread of the virus. Symptoms may begin to appear within 3 weeks of exposure to the virus [1]. In some rare cases, some individuals may be able to transmit the virus one to four days before symptoms appear, although the frequency of this is not precisely known [1].

Symptom Onset and Recovery Period

Mpox symptoms typically develop in stages. Symptoms often begin with fever, chills, swollen lymph nodes, exhaustion, headache, and muscle and back aches [1]. Subsequently, a rash appears in the form of blisters or pimples, which can appear on the face, inside the mouth, and on other parts of the body such as the hands, feet, chest, genitals, or anus [1]. This rash progresses through different stages, including scabbing, before healing completely [1].

The period for symptom onset and rash healing typically lasts from two to four weeks [1]. Throughout this entire period, the person is considered contagious. Therefore, individuals with mpox must stay home and isolate themselves from others until the rash has healed completely and a fresh layer of skin has formed [1].

How to Reduce the Risk of Transmission

To reduce the risk of mpox transmission, infected individuals must follow strict guidelines. It is advised to stay in a separate room from family members and pets if possible [1]. Close physical contact—including kissing, hugging, cuddling, or sexual activity—should be avoided with anyone who has a rash that resembles mpox [1].

Avoid touching items used by someone with mpox, such as bedding, towels, or clothing [1]. You should also not share eating utensils or cups [1]. If someone with mpox lives in the home, it is essential to clean and disinfect the house regularly [1]. Washing hands frequently with soap and water or using an alcohol-based hand sanitizer is essential, especially after contact with infected people [1].

When Can Normal Activities Resume?

A person with mpox can return to normal activities only after confirming that all skin lesions have healed completely and a fresh layer of skin has formed [1]. This means all scabs must have fallen off, and there are no active blisters or sores. You should consult a healthcare provider to confirm full recovery before ending isolation [3].
