Mpox is caused by monkeypox virus and spreads mainly through close contact with lesions, scabs, body fluids, or contaminated materials. Anyone can acquire it, and the disease should not be tied to a gender identity or sexual orientation.
Symptoms and testing
Symptoms usually begin within 21 days of exposure and may include fever, chills, swollen lymph nodes, tiredness, muscle aches, headache, respiratory symptoms, and a rash. Some people have only a few localised lesions and no recognised fever. Herpes, syphilis, chickenpox, folliculitis, and other conditions can look similar, so testing uses specimens from accessible lesions rather than a photograph alone.
What to do if mpox is possible
Avoid kissing, hugging, massage, sex, and direct lesion contact; cover lesions when possible; do not share towels, bedding, clothing, dishes, or sex toys; wash hands; and contact the service before arrival. People can transmit mpox until every lesion has scabbed, the scabs have fallen off, and fresh skin has formed.
People with substantial immunosuppression, pregnancy, young age, or widespread skin disease may face more severe illness and should be assessed promptly. Vaccination may be used before exposure or after contact; local eligibility and availability must be confirmed with public-health services.
Close contact, contaminated items, and the infectious period
The clearest risk comes from direct contact with lesions, scabs, or body fluids and from prolonged close contact. Bedding, towels, clothing, sex toys, and other items can transmit infection when freshly contaminated. Condoms may reduce contact at covered sites but cannot protect skin elsewhere, so they should not be treated as complete mpox protection.
A person can pass mpox from the beginning of symptoms until every lesion has crusted, all scabs have separated, and healthy skin has formed underneath. The duration varies and may last several weeks. Follow local public-health advice rather than ending precautions after an arbitrary number of days.
Vaccination after exposure and supportive care
Post-exposure vaccination works best when arranged quickly. CDC guidance says vaccination within four days of exposure offers the best chance of preventing disease; vaccination from day 4 through day 14 may reduce severity if symptoms have not started. Vaccine access, eligibility, and schedules in Thailand can change, so confirm current arrangements with a health service.
Most people recover with supportive care, but pain control—especially for oral, genital, or rectal lesions—may require clinical help. Seek urgent care for eye symptoms, breathing difficulty, confusion, dehydration, uncontrolled pain, rapidly spreading lesions, or signs of bacterial infection. People with advanced or uncontrolled HIV need early assessment because severe mpox can progress quickly.
Frequently asked questions
Are mpox and monkeypox the same disease?
Yes. Mpox is the preferred current disease name for infection with monkeypox virus.
Do condoms fully prevent mpox?
No. They may reduce exposure at covered sites, but lesions and skin contact can occur elsewhere.
Can mpox occur without fever?
Yes. Some people have only a rash or a few lesions, although many other conditions can look similar and require assessment.
