What is Monkeypox? {#what-is-monkeypox}

Monkeypox is a viral disease that can infect both animals and humans. It belongs to the orthopoxvirus family, which also includes smallpox and cowpox. While often milder than smallpox, monkeypox can still cause significant illness. Understanding the disease, its symptoms, transmission, and prevention methods is crucial for mitigating its spread and protecting public health.

Understanding the Monkeypox Virus {#understanding-the-monkeypox-virus}

The monkeypox virus (MPXV) is a double-stranded DNA virus. There are two main clades: clade I (formerly known as the Congo Basin clade) and clade II (formerly known as the West African clade). Clade I has historically been associated with more severe disease and higher mortality rates than clade II. The virus’s natural reservoir is still not completely known, but it is believed to be among certain rodents and other small mammals in Africa.

Monkeypox Symptoms: What to Look For {#monkeypox-symptoms-what-to-look-for}

Monkeypox symptoms are similar to smallpox symptoms, but generally milder. The incubation period (time from infection to symptoms) is typically 7-14 days, but can range from 5-21 days. Initial symptoms often include:

• Fever
• Headache
• Muscle aches
• Backache
• Swollen lymph nodes (a key distinguishing feature from chickenpox or measles)
• Exhaustion

Within 1-3 days after the onset of fever, a rash develops. This rash typically starts on the face and then spreads to other parts of the body, including the hands, feet, and genitals. The rash progresses through several stages:

• Macules: Flat, discolored spots
• Papules: Raised bumps
• Vesicles: Small, fluid-filled blisters
• Pustules: Pus-filled blisters
• Scabs: The pustules eventually crust over and form scabs, which eventually fall off.

It’s important to note that the rash can be extremely painful. The entire process, from the appearance of the rash to the falling off of scabs, can take 2-4 weeks.

How Monkeypox Spreads: Transmission Routes {#how-monkeypox-spreads-transmission-routes}

Monkeypox can spread in several ways:

• Animal-to-human transmission: Through direct contact with an infected animal’s blood, bodily fluids, or lesions. This can occur through bites or scratches, or by handling infected animals.
• Human-to-human transmission: This occurs through close contact with respiratory secretions, lesions, or contaminated materials (e.g., bedding, clothing) of an infected person. Prolonged face-to-face contact is typically required for respiratory droplet transmission.
• Mother-to-fetus transmission: Monkeypox can be transmitted from a pregnant person to their fetus through the placenta.

The virus enters the body through broken skin (even if not visible), the respiratory tract, or the mucous membranes (eyes, nose, or mouth).

Monkeypox Diagnosis: How is it Detected? {#monkeypox-diagnosis-how-is-it-detected}

A diagnosis of monkeypox is typically made based on a combination of clinical presentation (symptoms) and laboratory testing. A healthcare provider will examine the rash and ask about any potential exposures. If monkeypox is suspected, a sample from a lesion (e.g., fluid or skin) is collected and sent to a laboratory for testing. The most common laboratory test is a polymerase chain reaction (PCR) assay, which detects the virus’s DNA.

Monkeypox Treatment: Available Options {#monkeypox-treatment-available-options}

In many cases, monkeypox is a self-limiting disease, meaning that it resolves on its own without specific treatment. Supportive care, such as managing pain and fever, keeping the lesions clean and dry, and preventing secondary infections, is often sufficient. However, antiviral medications may be used in more severe cases or in individuals at high risk of complications.

• Tecovirimat (Tpoxx): This antiviral drug is approved for the treatment of smallpox and has also been used to treat monkeypox. It works by inhibiting the spread of the virus within the body.
• Brincidofovir (Tembexa): Another antiviral drug approved for smallpox, brincidofovir has shown activity against orthopoxviruses in laboratory studies.

These medications are not always readily available and are typically reserved for severe cases or those at high risk.

Monkeypox Vaccine: Prevention Strategies {#monkeypox-vaccine-prevention-strategies}

Vaccination is a key strategy for preventing monkeypox. The JYNNEOS vaccine (also known as Imvamune or Imvanex) is a live, attenuated (weakened) virus vaccine approved for the prevention of smallpox and monkeypox. It is considered safer than older smallpox vaccines, as it does not replicate efficiently in human cells. The ACAM2000 vaccine is another vaccine that can be used to prevent monkeypox. However, it has a higher risk of side effects and is not recommended for everyone.

Vaccination is recommended for people who have been exposed to monkeypox or who are at high risk of exposure. This includes:

• Laboratory workers who handle orthopoxviruses.
• Healthcare workers who provide care to monkeypox patients.
• Individuals who have had close contact with someone infected with monkeypox.
• Men who have sex with men and who have multiple sexual partners or anonymous partners.

Monkeypox vs. Chickenpox: Key Differences {#monkeypox-vs-chickenpox-key-key-differences}

Monkeypox and chickenpox can both cause a rash, but there are some key differences that can help distinguish between the two:

• Swollen lymph nodes: Monkeypox typically causes swollen lymph nodes (lymphadenopathy), while chickenpox usually does not.
• Rash distribution: The monkeypox rash often starts on the face and spreads to other parts of the body, while the chickenpox rash typically starts on the trunk and then spreads outward.
• Rash appearance: The monkeypox rash progresses through distinct stages (macules, papules, vesicles, pustules, scabs), while the chickenpox rash tends to be more varied in appearance.
• Overall illness: Monkeypox is generally a more severe illness than chickenpox, with symptoms such as fever, headache, and muscle aches being more pronounced.

If you are unsure whether you have monkeypox or chickenpox, it is important to consult a healthcare provider for proper diagnosis and treatment.

Monkeypox and Animals: A Zoonotic Disease {#monkeypox-and-animals-a-zoonotic-disease}

Monkeypox is a zoonotic disease, meaning that it can be transmitted from animals to humans. The natural reservoir of the monkeypox virus is believed to be among certain rodents and other small mammals in Africa. Human infections can occur through direct contact with infected animals, such as through bites or scratches, or by handling infected animals. Preventing contact with wild animals, especially rodents, and practicing good hygiene when handling animals are important steps in reducing the risk of zoonotic transmission.

Global Monkeypox Outbreaks: A Historical Perspective {#global-monkeypox-outbreaks-a-historical-perspective}

The first documented case of monkeypox in humans was in 1970 in the Democratic Republic of Congo. Since then, monkeypox has been reported in several other African countries. In 2003, the first monkeypox outbreak outside of Africa occurred in the United States, linked to imported prairie dogs that had been infected with the virus. More recently, in 2022, a multi-country outbreak of monkeypox was reported, affecting countries in Europe, North America, and other regions. These outbreaks highlight the importance of global surveillance and preparedness for emerging infectious diseases.

Monkeypox Prevention Tips: Protecting Yourself and Others {#monkeypox-prevention-tips-protecting-yourself-and-others}

Here are some key steps you can take to prevent monkeypox:

• Avoid contact with animals that could harbor the virus (e.g., rodents, primates) especially if they are sick or dead.
• Avoid contact with any materials, such as bedding, that has been in contact with a sick animal.
• Isolate infected individuals: If you are infected with monkeypox, isolate yourself from others to prevent further spread.
• Practice good hand hygiene: Wash your hands frequently with soap and water, or use an alcohol-based hand sanitizer.
• Use personal protective equipment (PPE): When caring for someone with monkeypox, wear a mask, gloves, and gown to protect yourself.
• Get vaccinated: If you are at high risk of exposure, consider getting vaccinated against monkeypox.

Current Monkeypox Situation: Staying Informed {#current-monkeypox-situation-staying-informed}

The global monkeypox situation is constantly evolving. Stay informed about the latest updates and recommendations from reputable sources, such as the World Health Organization (WHO) and your local health authorities. This will help you make informed decisions about how to protect yourself and others.

Monkeypox: Debunking Common Myths {#monkeypox-debunking-common-myths}

There are many misconceptions about monkeypox. It is essential to rely on accurate information from reliable sources to avoid unnecessary fear and panic. Here are some common myths about monkeypox:

• Myth: Monkeypox is only a sexually transmitted infection (STI). While monkeypox can spread through close contact during sexual activity, it is not exclusively an STI. It can also spread through other forms of close contact, such as respiratory droplets or contact with contaminated materials.
• Myth: Monkeypox is a new disease. Monkeypox was first identified in 1958 and has been known to infect humans since 1970.
• Myth: Monkeypox is as deadly as smallpox. Monkeypox is generally milder than smallpox, with a lower mortality rate.
• Myth: Anyone can get monkeypox. While anyone can get monkeypox, certain groups are at higher risk, such as healthcare workers, laboratory workers, and people who have had close contact with infected individuals.

The Future of Monkeypox Research and Control {#the-future-of-monkeypox-research-and-control}
