Monkeypox, also known as mpox, is a viral illness caused by the mpox virus. This virus belongs to the Orthopoxvirus genus. The disease can cause a painful rash, swollen lymph nodes, and fever. Most people get better, but some may become very sick.
Mpox spreads through close contact with people who are infected, touching things they have touched, or touching animals that carry the virus. It’s important to know how to spot and handle mpox to stop it from spreading. This helps in giving the right care to those who get it.
Key Takeaways
- Monkeypox, or mpox, is a rare viral disease that can cause a painful rash, fever, and other symptoms.
- The virus can spread through close physical contact, contaminated materials, or contact with infected animals.
- While most people recover, some cases can be severe, especially in immunocompromised individuals.
- Antiviral treatments, such as tecovirimat, and vaccines like ACAM2000 and JYNNEOS may be used to manage monkeypox cases.
- Preventive measures, including avoiding close contact with infected individuals and practicing good hygiene, are essential to limit the spread of the virus.
What is Mpox, Previously Known as Monkeypox?
Mpox, once called monkeypox, is a rare disease caused by the mpox virus. This virus usually affects rodents and non-human primates but can also infect humans. It’s mostly found in Central and West Africa. Cases outside Africa are often linked to travel, animals, or close contact with someone or animal infected.
The mpox virus is part of the Orthopoxvirus genus, which includes the smallpox virus. In November 2022, the World Health Organization (WHO) renamed it from monkeypox to mpox to reduce stigma.
Mpox vs. Smallpox and Chickenpox
Mpox is less severe than smallpox. Its symptoms are different from chickenpox, caused by a different virus. The Mayo Clinic says mpox causes fever, skin rash, swollen lymph nodes, and flu-like symptoms. Chickenpox, on the other hand, has an itchy, blister-like rash.
| Characteristic | Mpox | Smallpox | Chickenpox |
|---|---|---|---|
| Causative Virus | Mpox virus | Smallpox virus | Varicella-zoster virus |
| Typical Symptoms | Fever, skin rash, swollen lymph nodes | Fever, severe rash with fluid-filled blisters | Itchy, blister-like rash |
| Severity | Generally less severe than smallpox | More severe than mpox | Milder than mpox or smallpox |
Common Symptoms of Mpox
Monkeypox, now known as mpox, often shows certain symptoms. These include fever, skin rash, swollen lymph nodes, headache, muscle aches, chills, and more. These signs can be mild or severe and usually go away in 2-4 weeks.
The Mpox Rash
The mpox rash is a key sign of the disease. It starts on the face, hands, or feet and can spread. The rash changes, starting as flat spots, then becoming blisters, and finally scabbing over before falling off.
Some people may also experience monkeypox fever, monkeypox lymph nodes, and rashes on sensitive areas like the genitals, anus, or mouth. In severe cases, mpox can cause skin or blood infections, brain inflammation, heart problems, and lung infections.
| Symptom | Description |
|---|---|
| Fever | Elevated body temperature, often accompanied by chills and fatigue. |
| Monkeypox Rash | A distinctive rash that goes through various stages, including flat spots, blisters, and scabs. |
| Monkeypox Lymph Nodes | Swelling and tenderness in the lymph nodes, often in the neck, armpits, or groin. |
| Headache | Persistent or severe headaches can be a common symptom. |
| Muscle Aches | Widespread muscle and body aches, including backaches, are frequently reported. |
| Chills | Episodes of shivering or feeling cold, often accompanied by a fever. |
| Tiredness | General feelings of fatigue and lack of energy. |
While these are the main symptoms of monkeypox, the disease can affect people differently. It’s crucial to see a doctor quickly for the right diagnosis and treatment.
The Mpox Rash
The monkeypox skin rash is a key sign of the mpox virus. It can show up anywhere, like the palms, soles, face, and groin. The rash starts as flat monkeypox lesions that turn into blisters. Then, the monkeypox sores dry up, crust over, and fall off.
Some people get just a few skin lesions, while others get hundreds. The mpox rash stages can differ, sometimes staying in one area like the groin.
« During previous outbreaks, people with mpox had between 10 and 150 pox-like bumps on their skin, while in 2022, individuals may only develop a few bumps instead of hundreds. »
If you get a new, unexplained skin rash or lesions, see a doctor right away. They can test you for the mpox virus with a PCR test. Even though there’s no special treatment, doctors can help manage the rash and prevent problems.
| Mpox Rash Statistics | Details |
|---|---|
| FDA-approved vaccine | The JYNNEOS® vaccine is the only mpox vaccine approved for use in the U.S. |
| Rashes not caused by mpox | Most rashes seen by dermatologists are currently not caused by mpox. |
| Pox-like bumps during outbreaks | Previously, individuals with mpox had 10-150 pox-like bumps, but in 2022, they may only develop a few bumps. |
| Smallpox vaccine effectiveness | The smallpox vaccine is approximately 85% effective in preventing mpox. |
| Mpox contagious period | Mpox lasts for 2 to 4 weeks, during which time the infected individual is contagious. |
How Does the Mpox Virus Spread?
The monkeypox virus, also known as the mpox virus, spreads in several ways. It’s important to know these ways to stop the virus from spreading.
Direct Contact
The mpox virus spreads mainly through direct contact with infected skin, scabs, or fluids. This often happens during close, intimate activities like sex.
Respiratory Droplets
Being near someone who has the virus and breathing in their droplets can also spread the virus. This is more likely in close, face-to-face situations or places with bad air flow.
Contaminated Materials
Touching things that an infected person or animal has touched can also spread the virus. This includes clothes, bedding, or other items they’ve been near.
Animal-to-Human Transmission
Animals like rodents and non-human primates can give the virus to humans. This can happen through bites, scratches, or touching them. Eating infected wild game is another way humans can get it from animals.
People with the mpox virus can spread it from the start of symptoms until their scabs fall off and their skin heals. Pregnant women can also pass it to their babies.
| Transmission Mode | Description |
|---|---|
| Direct Contact | Skin lesions, scabs, or body fluids of an infected person, including during sexual activity |
| Respiratory Droplets | Extended close contact with respiratory droplets from an infected individual |
| Contaminated Materials | Clothing, bedding, or other items that have been in close proximity to an infected person or animal |
| Animal-to-Human | Bites, scratches, or handling of infected rodents or non-human primates, and consuming infected wild game |
« Individuals infected with the mpox virus can be contagious from the onset of symptoms until the scabs have naturally fallen off and the skin has fully healed. »
Preventing Mpox Infection
The spread of mpox, also known as monkeypox, is a growing concern. To prevent infection, it’s important to avoid close contact with someone who has the virus. Also, don’t touch items that have been near an infected person or animal.
Practicing proper hygiene is also key in preventing mpox. Wash your hands often with soap and water or use an alcohol-based hand sanitizer. This is crucial after any possible exposure to someone who might be infected.
Vaccination: A Protective Measure
Vaccines for smallpox can help prevent mpox in some cases. They are mainly for those at high risk, like healthcare workers or people with many sexual partners. The FDA has approved two vaccines, JYNNEOS and ACAM2000, for people 18 and older at high risk of getting infected.
- The CDC suggests vaccination for those at high risk to prevent mpox.
- Tecovirimat, a smallpox treatment, is now used to treat mpox first.
- Mpox is similar to smallpox, so we can use smallpox vaccines and treatments for it too.
By taking these steps and staying updated on mpox vaccines and treatments, we can protect our health. This helps slow down the spread of this new disease.
symptoms and treatment options for monkeypox
Monkeypox, also known as mpox, is a rare but serious viral illness. It can cause fever, skin rash, swollen lymph nodes, headache, muscle aches, and fatigue. These symptoms usually start 3 to 17 days after getting the virus and can last 2 to 4 weeks.
There are no specific treatments for monkeypox. But, doctors might use certain antiviral drugs or vaccinia immune globulin (VIGIV) in some cases. These treatments aim to manage the infection and help patients recover.
- Tecovirimat is often the first treatment for patients needing more than just supportive care.
- Brincidofovir and Vaccinia Immune Globulin (VIGIV) are used under certain conditions.
- Trifluridine ophthalmic solution is for monkeypox eye infections.
Cidofovir, an antiviral drug for CMV retinitis, might be used for monkeypox too. But, it’s mainly for severely weakened people, often with tecovirimat.
Stopping monkeypox from spreading is key. Avoid close contact with those who are infected, wash hands well, and consider getting vaccinated with smallpox vaccines like ACAM2000 and Jynneos. These steps can lower the chance of getting the virus.
Potential Complications of Mpox
Monkeypox is usually a self-limiting illness but can cause serious issues, especially for those with weak immune systems. This includes people with HIV or those getting cancer treatment. These complications can result in scarring or even blindness, and in rare cases, death.
Children and pregnant women are at a higher risk for severe monkeypox complications. Their immune systems may struggle to fight the virus, leading to worse symptoms and complications.
One big worry is getting secondary infections. The monkeypox virus can weaken the immune system. This makes people more likely to get infections that could be deadly if not treated.
Quick treatment and care are key to avoiding these monkeypox complications. Early action, like using antiviral drugs and managing infections, can greatly improve recovery chances and lower the risk of long-term problems.
People with compromised immune systems or close contact with someone with monkeypox should watch for symptoms and seek medical help right away. This helps them get the care they need to avoid severe monkeypox complications and recover fully.
Mpox Vaccines and Treatments
There is no specific treatment for mpox yet. But, doctors might use certain antiviral drugs or vaccinia immune globulin in some cases. Also, vaccines like ACAM2000 and Jynneos can prevent mpox because it’s related to smallpox.
Antiviral Drugs and Immune Globulin
Doctors might give antiviral drugs like tecovirimat (TPOXX) and brincidofovir (Tembexa) to people with severe symptoms or weak immune systems. Vaccinia immune globulin, which has antibodies against the vaccinia virus, can also be used in some cases.
Smallpox Vaccines for Mpox Prevention
Smallpox vaccines, including ACAM2000 and Jynneos, can protect against mpox since the viruses are related. These vaccines might be suggested for people at high risk, like healthcare workers or those close to someone infected.
The STOMP Trial, a study on tecovirimat for mpox treatment, is happening now. Patients can join this trial, which covers costs for time and travel. But, joining is not needed to get TPOXX treatment.
There are resources for mpox treatment in many languages. This ensures everyone gets the care they need, no matter their language.
Mpox and Other Poxviruses
The recent outbreak of monkeypox, or mpox, has made it crucial to know how it relates to other poxviruses. Mpox comes from a virus in the Orthopoxvirus group, which also includes the smallpox virus. While both cause skin rashes, mpox is usually less severe and spreads less easily than smallpox.
It’s important to tell mpox apart from chickenpox for correct diagnosis and treatment. Chickenpox, caused by the varicella-zoster virus, has a unique rash that’s different from mpox. Knowing these differences helps doctors give the best care and stop the spread of these diseases.
Studies have shown how mpox is changing. In 2022, a big outbreak happened worldwide, as seen on the Centers for Disease Control and Prevention’s 2022 Monkeypox Outbreak Global Map. A study in Nature in August 2023 found more mpox cases and a new way it spreads, through sex.
There have been steps forward in preventing these diseases. In September 2019, the U.S. Food and Drug Administration approved a vaccine for smallpox and mpox prevention. This is a big help in fighting these viruses.
As doctors learn more about mpox and other poxviruses, it’s vital to keep up with the latest information. By understanding these diseases, doctors and everyone else can help reduce the effects of mpox and other outbreaks.
Mpox Transmission from Animals
Mpox, also known as monkeypox, spreads from animals to humans. It’s a zoonotic disease. The main animals carrying the virus are small mammals like rodents and primates. They live mainly in Central and West Africa.
People can get mpox through animal bites, scratches, or touching infected animals. Eating infected wild game can also spread the virus. This way of spreading the disease is key to understanding how it moves from animals to humans.
The 2022–2023 global mpox outbreak showed us how important it is to study this disease. We need to know how animals spread mpox. This knowledge helps doctors, policymakers, and everyone else to prevent more outbreaks.
| Characteristic | Details |
|---|---|
| Natural Reservoir | Rodents and primates in Central and West Africa |
| Transmission Routes |
|
| Outbreak Context | Global outbreak of mpox in 2022–2023, caused by clade IIb strain |
Learning about the monkeypox animal reservoir and how it spreads helps us fight the disease. Together, healthcare workers, health officials, and the public can stop the spread of this monkeypox zoonotic disease.
Mpox and Pregnancy
The recent mpox (previously known as monkeypox) outbreak has raised concerns for pregnant people. Monkeypox in pregnancy, monkeypox transmission during pregnancy, and monkeypox complications in pregnancy are now key topics.
Pregnant people are more at risk of mpox complications. The virus can cross the placenta to the baby. This can cause severe illness, hospital stays, and risks like premature birth or losing the pregnancy.
Healthcare providers keep a close watch on pregnant people with mpox. They offer support to both the mom and the growing baby. Vaccines and prevention are key to protecting pregnant people.
| Potential Mpox Complications in Pregnancy | Recommendations for Pregnant Individuals |
|---|---|

Our understanding of monkeypox in pregnancy is still growing. But, healthcare workers are working hard to help pregnant people. By staying informed and careful, pregnant people can protect themselves and their babies during this tough time.
Mpox and Immunocompromised Individuals
People with weak immune systems, like those with HIV or cancer, are at higher risk of severe monkeypox (mpox) complications. These can include longer illness, bigger skin lesions, and a higher chance of needing hospital care or even dying.
A 2022 study by Sigler and Haidar found that monkeypox in HIV or monkeypox in cancer patients needs special care. These patients might need extra help to fight the infection and avoid serious problems. Doctors should watch these patients closely and give them the right treatment.
The effects of monkeypox in immunocompromised patients can be very serious. A 1997 study by Mukinda et al. talked about monkeypox coming back in Zaire. A 2019 review by Beer and Rao highlighted the challenges faced by those with weak immune systems.
| Statistic | Source |
|---|---|
| In 2022, a study by Sigler and Haidar focused on Mpox in immunocompromised patients. | Sigler and Haidar, 2022 |
| A research article by Mukinda et al. in 1997 reported the re-emergence of human monkeypox in Zaire. | Mukinda et al., 1997 |
| A review by Beer and Rao in 2019 discussed the epidemiology of human monkeypox outbreaks. | Beer and Rao, 2019 |
As scientists learn more about monkeypox in immunocompromised people, doctors must keep a close watch. They need to give full care and support to those at risk.
