Mpox Explained: Symptoms, Causes, And Prevention
Mpox, formerly known as monkeypox, is a viral disease that can infect both animals and humans. Understanding what mpox is, how it spreads, and what measures can be taken to prevent it is crucial for public health. This article provides a comprehensive overview of mpox, covering its symptoms, causes, and prevention strategies.
What is Mpox?
Mpox is caused by the mpox virus, a member of the Orthopoxvirus genus, which includes the variola virus (the cause of smallpox). Although less deadly than smallpox, mpox can still cause significant illness. The name change from monkeypox to mpox was implemented by the World Health Organization (WHO) to avoid stigma and reflect the disease's broader impact beyond monkeys.
Symptoms of Mpox
The symptoms of mpox typically appear in stages:
- Incubation Period: Usually 6-13 days, but can range from 5-21 days, during which there are no symptoms.
- Initial Symptoms: These include fever, headache, muscle aches, back pain, swollen lymph nodes, and exhaustion.
- Rash Development: Within one to three days after the onset of fever, a rash appears. The rash evolves through several stages:
- Macules: Flat, discolored spots.
- Papules: Raised bumps.
- Vesicles: Small, fluid-filled blisters.
- Pustules: Pus-filled blisters.
- Scabs: The blisters eventually 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. The illness typically lasts for two to four weeks.
How Mpox Spreads
Mpox can spread through several routes:
- Animal-to-Human Transmission:
- Contact with infected animals (through bites, scratches, or handling wild game).
- Human-to-Human Transmission:
- Direct contact with mpox rash, scabs, or body fluids.
- Respiratory secretions during prolonged face-to-face contact.
- Contact with contaminated materials such as clothing or bedding.
- Mother-to-Fetus Transmission:
- Mpox can be transmitted from a pregnant woman to her fetus.
It is important to note that mpox is not as contagious as some other viral diseases like measles or chickenpox.
Prevention Strategies
Several measures can be taken to prevent the spread of mpox:
- Vaccination: Vaccines developed for smallpox, such as the JYNNEOS vaccine, have been shown to be effective in protecting against mpox. Vaccination is recommended for people at high risk of exposure.
- Avoid Contact with Infected Animals: In areas where mpox is endemic, avoid contact with rodents and primates, and always cook animal products thoroughly before eating.
- Practice Good Hygiene: Frequently wash your hands with soap and water or use an alcohol-based hand sanitizer, especially after contact with potentially infected people or animals.
- Avoid Contact with Infected People: If someone has mpox, avoid close physical contact with them, and do not share personal items such as clothing, bedding, or towels.
- Use Personal Protective Equipment (PPE): Healthcare workers and others who may be exposed to mpox should use appropriate PPE, including gloves, gowns, and masks.
Diagnosis and Treatment
Mpox is typically diagnosed based on the appearance of the rash and a history of potential exposure. Diagnostic testing, such as PCR, can confirm the presence of the mpox virus. Treatment for mpox is primarily supportive, focusing on relieving symptoms and preventing complications. Antiviral medications, such as tecovirimat (TPOXX), may be used in severe cases or for people at high risk of complications.
Mpox vs. Chickenpox
Mpox and chickenpox can present with similar symptoms, particularly the rash. However, there are some key differences:
- Lymphadenopathy: Swollen lymph nodes are a common symptom of mpox but not of chickenpox.
- Rash Distribution: The mpox rash tends to be more concentrated on the face, palms, and soles, whereas the chickenpox rash is more widespread.
- Rash Development: The mpox rash progresses through distinct stages (macules, papules, vesicles, pustules, scabs), while the chickenpox rash may have lesions in various stages at the same time.
Conclusion
Mpox is a viral disease that requires public awareness and preventive measures to control its spread. By understanding the symptoms, transmission routes, and prevention strategies, individuals and communities can take effective steps to protect themselves and others. Vaccination, good hygiene practices, and avoiding contact with infected animals and people are key to preventing mpox.
