What is Mpox?
Mpox is a rare disease caused by infection with the mpox virus. Mpox virus is part of the same family of viruses as smallpox. Mpox symptoms are similar to smallpox symptoms, but milder and mpox is rarely fatal. Mpox is not related to chickenpox.
Human monkeypox was given its name in 1958, before the publication of WHO’s best practices in naming diseases was published in 2015. According to the WHO’s best practices, new disease names should be given with the aim to minimize unnecessary negative impact of names on trade, travel, tourism, or animal welfare, and avoid causing offense to any cultural, social, national, regional, professional, or ethnic groups.
In support of the November 28, 2022 recommendation by the World Health Organization (WHO) and Health and Human Services (HHS), CDC will adopt “mpox” as the term used to refer to monkeypox disease.
Symptoms of Mpox
- Flu-like symptoms such as fever, headache, muscle aches, chills, swollen lymph nodes and fatigue. These symptoms may occur before or after the rash appears, or not at all.
- A rash that
- Can look like pimples or blisters that appears on the face, inside the mouth, and on other body parts like the hands, feet, chest, genitals, or anus.
- The rash goes through different stages before healing completely.
- View examples of mpox rashes here.
- The illness typically lasts 2-4 weeks.
How Mpox is Spread
Mpox is spread through close, physical contact between individuals. This includes:
- Direct contact with mpox sores or rashes on an individual who has mpox.
- Respiratory droplets or oral fluids from someone with mpox, particularly for those who have close contact with someone or are around them for a long period of time.
- It can also be spread through contact with objects or fabrics (e.g., clothing, bedding, towels) that have been used by someone with mpox.
- JYNNEOS (also known as Imvamune or Imvanex) is a vaccine licensed by the U.S. Food and Drug Administration (FDA) to prevent mpox and can be used before and after exposure to mpox.
- CDC recommends vaccination for people who have been exposed to mpox and people who are at higher risk of being exposed to mpox.
- JYNNEOS is given in a 2 dose series. Your 2nd dose of vaccine is due 28 days after your 1st dose. Individuals are considered to be fully vaccinated about 2 weeks after their 2nd dose of JYNNEOS.
- If the vaccine is given before exposure or within 4 days of exposure, this vaccine may reduce the likelihood of infection, and within 14 days, it may reduce severity of symptoms.
