What is Monkeypox?
MOnkeypox is a viral disease that can infect both animals and humans. It is caused by the monkeypox virus, which belongs to the Orthopoxvirus genus. This genus includes other viruses like the variola virus (which causes smallpox), vaccinia virus (used in the smallpox vaccine), and cowpox virus. While the name suggests monkeys are the primary carriers, monkeypox is more commonly found in rodents.
Monkeypox was first discovered in 1958 when two outbreaks of a pox-like disease occurred in colonies of monkeys kept for research. The first human case was recorded in 1970 in the Democratic Republic of Congo.
Although less deadly than smallpox (which was eradicated in 1980), monkeypox can cause significant illness, with symptoms including fever, headache, muscle aches, swollen lymph nodes, and a characteristic rash that turns into blisters before scabbing over.
In recent years, cases of monkeypox have been reported in several countries, leading to increased public health concerns and research efforts to understand and control the spread of the virus. Staying informed about monkeypox, its symptoms, transmission, and prevention methods is crucial for protecting ourselves and our communities.
Monkeypox vs. Chickenpox vs. Smallpox
It’s easy to confuse monkeypox with other diseases that cause similar rashes, such as chickenpox and smallpox. Here’s a quick comparison:
- Monkeypox: Caused by the monkeypox virus. Symptoms include fever, headache, muscle aches, swollen lymph nodes, and a rash that develops into blisters. Less deadly than smallpox.
- Chickenpox: Caused by the varicella-zoster virus. Symptoms include an itchy rash with small, fluid-filled blisters, fever, and fatigue. Generally milder than monkeypox, and a vaccine is available.
- Smallpox: Caused by the variola virus. Symptoms include fever, fatigue, head and back aches, and a characteristic rash of raised, fluid-filled bumps. Smallpox was eradicated in 1980, and vaccination has stopped. It was more deadly than monkeypox.
Key differences include the appearance and progression of the rash, the presence of swollen lymph nodes (more common in monkeypox), and the overall severity of the illness. If you suspect you have any of these diseases, it’s essential to consult a healthcare professional for an accurate diagnosis.
Symptoms of Monkeypox
The incubation period for monkeypox (the time from infection to the start of symptoms) is typically 7-14 days but can range from 5-21 days. The illness usually lasts for 2-4 weeks. Symptoms of monkeypox typically occur in two stages:
1. Invasion Period (0-5 days):
Fever
Headache
Muscle aches (myalgia)
Back pain
Swollen lymph nodes (lymphadenopathy) – a key feature that distinguishes monkeypox from chickenpox or smallpox.
Chills
Exhaustion
2. Skin Eruption Period (within 1-3 days of fever):
Rash begins as flat, red bumps (macules)
Bumps become raised (papules)
Papules fill with clear fluid (vesicles)
Vesicles fill with pus (pustules)
Pustules crust over and form scabs
* The rash often starts on the face and then spreads to other parts of the body, including the palms of the hands and soles of the feet. Lesions can also occur inside the mouth, on the genitals, and around the eyes.
It’s important to note that not everyone experiences all the symptoms, and the severity of the illness can vary. Some individuals may only develop a mild rash, while others may experience more severe symptoms and complications.
How Monkeypox Spreads
Monkeypox spreads through various routes. Understanding these routes is crucial for implementing effective prevention strategies:
- Animal-to-Human Transmission (Zoonotic Transmission): This can occur through direct contact with an infected animal’s blood, bodily fluids, or skin lesions. Handling or eating inadequately cooked meat from infected animals can also transmit the virus.
- Human-to-Human Transmission:
- Direct Contact: Close physical contact with an infected person’s rash, scabs, or bodily fluids is a primary mode of transmission. This can happen during sexual contact, hugging, kissing, or caring for someone with monkeypox.
- Respiratory Droplets: Prolonged face-to-face contact can spread the virus through respiratory droplets. However, this is not the main route of transmission, as it typically requires extended interaction.
- Contaminated Materials: Touching items such as clothing, bedding, or towels that have been contaminated with the virus can lead to infection.
- Mother-to-Fetus Transmission: Monkeypox can spread from a pregnant person to their fetus through the placenta.
It’s important to note that scientists are still learning about the different ways monkeypox spreads. Current evidence suggests that direct contact with lesions is a significant factor in transmission.
Monkeypox Transmission: Who is at Risk?
While anyone can contract monkeypox, certain groups may be at higher risk:
- People who have close contact with someone infected with monkeypox: This includes household members, sexual partners, and healthcare workers.
- People who have contact with infected animals: Hunters, veterinarians, and others who handle animals in areas where monkeypox is present may be at higher risk.
- Healthcare workers: Healthcare professionals who care for patients with monkeypox are at risk of exposure if they do not use proper personal protective equipment (PPE).
- Immunocompromised individuals: People with weakened immune systems may be at higher risk of severe illness if they contract monkeypox.
- Children: Children, especially those under 8 years old, may be at increased risk for severe outcomes.
It’s important to remember that being in a high-risk group doesn’t guarantee infection, but it does mean that extra precautions should be taken to minimize exposure.
Monkeypox Diagnosis
Diagnosing monkeypox involves a combination of clinical evaluation and laboratory testing:
- Clinical Evaluation: A healthcare provider will assess your symptoms, medical history, and potential exposure to the virus. The characteristic rash and swollen lymph nodes are key indicators.
- Laboratory Testing: To confirm a diagnosis, a sample from a lesion (such as fluid or a scab) is collected and sent to a laboratory for testing. The most common tests include:
- Polymerase Chain Reaction (PCR) Testing: This test detects the presence of the monkeypox virus’s genetic material.
- Viral Culture: This involves growing the virus in a laboratory to identify it.
- Serological Testing: These tests detect antibodies against the monkeypox virus in the blood. However, they can be difficult to interpret due to cross-reactivity with other orthopoxviruses.
It’s important to note that monkeypox can be confused with other diseases that cause similar rashes, such as chickenpox, measles, and herpes. Therefore, laboratory testing is crucial for accurate diagnosis.
Monkeypox Treatment
Most people with monkeypox have a mild, self-limiting illness that resolves on its own within 2-4 weeks. Treatment focuses on relieving symptoms and preventing complications:
- Supportive Care:
- Pain relievers (such as acetaminophen or ibuprofen) to manage fever and muscle aches
- Antihistamines to relieve itching
- Adequate hydration
- Rest
- Skin Care:
- Keeping the rash clean and dry
- Applying topical antibiotics to prevent secondary bacterial infections
- Covering lesions to prevent spread
- Antiviral Medications: In severe cases or for people at high risk of complications, antiviral medications may be used. Examples include:
- Tecovirimat (Tpoxx): This drug inhibits the spread of the virus within the body.
- Brincidofovir (Tembexa): Another antiviral medication that can be used to treat monkeypox.
- Vaccinia Immune Globulin Intravenous (VIGIV): This contains antibodies against orthopoxviruses and may be used in severe cases or for people with weakened immune systems.
It’s important to consult with a healthcare professional to determine the best course of treatment for your specific situation.
Monkeypox Prevention: Vaccination and Other Measures
Several measures can be taken to prevent the spread of monkeypox:
- Vaccination:
- JYNNEOS (Imvamune or Imvanex): This is a newer vaccine approved for the prevention of monkeypox and smallpox. It is a two-dose vaccine administered 28 days apart.
- ACAM2000: This is an older smallpox vaccine that can also provide protection against monkeypox. However, it has more side effects and is not recommended for everyone.
- Avoid Contact:
- Avoid close contact with people who have monkeypox.
- Avoid contact with wild animals that could be infected with the virus.
- Do not handle items that may have been contaminated with the virus, such as bedding or clothing.
- Practice Good Hygiene:
- Wash your hands frequently with soap and water or use an alcohol-based hand sanitizer.
- Avoid touching your eyes, nose, and mouth.
- Use Personal Protective Equipment (PPE):
- Healthcare workers and others who may be exposed to monkeypox should use appropriate PPE, such as gloves, gowns, and masks.
- Safe Sexual Practices:
- Be aware of the symptoms of monkeypox and avoid close contact with anyone who has a rash that looks like monkeypox.
Vaccination is a highly effective way to prevent monkeypox, especially for people at high risk of exposure.
The Future of Monkeypox: What to Expect
The future of monkeypox is uncertain, but several factors will likely influence its trajectory:
- Continued Surveillance: Ongoing surveillance is crucial for detecting and responding to outbreaks quickly.
- Vaccination Efforts: Expanding vaccination efforts, particularly among high-risk groups, can help control the spread of the virus.
- Research: Continued research is needed to better understand the virus, its transmission dynamics, and the effectiveness of different prevention and treatment strategies.
- Public Health Education: Raising awareness about monkeypox and its prevention is essential for empowering individuals to protect themselves and their communities.
- Global Collaboration: International collaboration is needed to coordinate surveillance, research, and response efforts.
While monkeypox is unlikely to become a global pandemic like COVID-19, it is important to remain vigilant and take appropriate measures to prevent its spread.
