What is Monkeypox? {#what-is-monkeypox}
Monkeypox is a viral disease that can occur in both humans and animals. It’s caused by the monkeypox virus, a member of the Orthopoxvirus genus, which also includes the variola virus (the cause of smallpox). While the name suggests monkeys are the primary carriers, the natural reservoir of the virus is still unknown, but it’s suspected to be rodents in Africa.
Key facts about Monkeypox:
- It was first discovered in 1958 in laboratory monkeys.
- The first human case was recorded in 1970 in the Democratic Republic of Congo.
- It’s less contagious than smallpox and generally causes milder illness.
- There are two distinct genetic clades of the monkeypox virus: the Central African (Congo Basin) clade and the West African clade. The Congo Basin clade is historically associated with more severe disease.
Understanding what monkeypox is, its origins, and its relationship to other viruses like smallpox is the first step in addressing concerns and mitigating its spread.
Monkeypox vs. Chickenpox: Understanding the Differences {#monkeypox-vs-chickenpox-understanding-the-differences}
It’s easy to confuse monkeypox with chickenpox, as both diseases present with rashes that can appear similar at first glance. However, there are crucial differences:
- Cause: Monkeypox is caused by the monkeypox virus, while chickenpox is caused by the varicella-zoster virus.
- Rash Development: In monkeypox, the rash progresses through distinct stages: macules (flat spots), papules (raised bumps), vesicles (small fluid-filled blisters), and pustules (pus-filled blisters) before scabbing over. All lesions tend to be at the same stage of development on any given part of the body. Chickenpox lesions, on the other hand, appear in crops, meaning that lesions in various stages of development (new, raised, fluid-filled, scabbed over) are present simultaneously.
- Lymph Node Swelling: A key distinguishing feature of monkeypox is lymph node swelling (lymphadenopathy), which is not typically seen in chickenpox.
- Severity: Monkeypox is generally more severe than chickenpox, although the severity can vary depending on the viral clade and the individual’s health status.
Knowing these differences is critical for accurate diagnosis and appropriate medical care.
Symptoms of Monkeypox {#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. Symptoms usually begin with:
- Fever
- Headache
- Muscle aches
- Backache
- Swollen lymph nodes (lymphadenopathy)
- Exhaustion
The characteristic rash typically appears 1-3 days after the onset of fever. 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 lesions progress through the stages mentioned earlier: macules, papules, vesicles, and pustules, before finally scabbing over. The illness typically lasts for 2-4 weeks.
It’s important to note that some individuals may experience milder symptoms, especially with the West African clade. Early recognition of these symptoms is essential for preventing further transmission.
How Monkeypox Spreads {#how-monkeypox-spreads}
Monkeypox can spread through several ways:
- Animal-to-human transmission: This can occur through direct contact with an infected animal’s blood, bodily fluids, or cutaneous or mucosal lesions. Handling wild animals or consuming inadequately cooked meat from infected animals are potential routes of transmission.
- Human-to-human transmission: This occurs through close contact with respiratory secretions, skin lesions (including scabs), or contaminated materials (such as bedding) of an infected person. Prolonged face-to-face contact is generally required for respiratory droplet transmission. Direct contact with lesion material or fluids is a more efficient means of transmission.
- Mother-to-fetus transmission: Monkeypox can be transmitted from a pregnant person to their fetus via the placenta.
It’s crucial to understand these transmission routes to implement effective prevention strategies.
Risk Factors for Monkeypox Infection {#risk-factors-for-monkeypox-infection}
Certain factors can increase the risk of monkeypox infection:
- Close contact with infected individuals: This includes household members, healthcare workers, and sexual partners of infected individuals.
- Contact with infected animals: This is particularly relevant in regions where monkeypox is endemic.
- Lack of vaccination: Prior vaccination against smallpox offers some cross-protection against monkeypox. Therefore, individuals who have not been vaccinated against smallpox (particularly those born after the eradication of smallpox) may be at higher risk.
- Weakened immune system: People with compromised immune systems may be more likely to develop severe illness.
Identifying and addressing these risk factors can help to protect vulnerable populations.
Diagnosis of Monkeypox {#diagnosis-of-monkeypox}
Diagnosis of monkeypox typically involves:
- Clinical assessment: A healthcare provider will evaluate the patient’s symptoms and medical history.
- Laboratory testing: A sample from a skin lesion (fluid or crust) is collected and sent to a laboratory for PCR (polymerase chain reaction) testing to detect the monkeypox virus DNA. This is the preferred laboratory test.
- Other tests: In some cases, other tests, such as serology (antibody testing), may be used, but these are less reliable for acute diagnosis.
Accurate and timely diagnosis is crucial for implementing appropriate infection control measures and providing proper treatment.
Monkeypox Treatment Options {#monkeypox-treatment-options}
Most people with monkeypox recover on their own without specific treatment. However, supportive care can help relieve symptoms and prevent complications. This may include:
- Pain relievers
- Fever reducers
- Wound care to prevent secondary bacterial infections
Antiviral Medications:
- Tecovirimat (Tpoxx): This antiviral medication is approved for the treatment of smallpox and is also available for monkeypox under certain circumstances. It works by inhibiting the spread of the virus within the body.
- Brincidofovir (Tembexa): Another antiviral medication that may be considered in severe cases.
Vaccinia Immune Globulin Intravenous (VIGIV):
- This is an antibody treatment derived from people vaccinated against smallpox. It may be considered for severe cases or for people with weakened immune systems.
Treatment decisions are made on a case-by-case basis, taking into account the severity of the illness, the individual’s health status, and other factors.
Preventing the Spread of Monkeypox {#preventing-the-spread-of-monkeypox}
Preventing the spread of monkeypox involves a combination of strategies:
- Avoid contact with infected animals: In areas where monkeypox is endemic, avoid contact with rodents and primates. Cook meat thoroughly.
- Practice good hygiene: Wash hands frequently with soap and water, especially after contact with potentially contaminated surfaces or individuals.
- Avoid contact with infected individuals: If someone has monkeypox, avoid close contact with them. Wear a mask if you need to be near them.
- Use personal protective equipment (PPE): Healthcare workers and others who may be exposed to monkeypox should wear appropriate PPE, including gloves, gowns, and masks.
- Isolate infected individuals: People with monkeypox should isolate themselves until their lesions have completely healed and the scabs have fallen off.
- Vaccination: Vaccination against smallpox (or monkeypox vaccine) can help to prevent infection or reduce the severity of the illness.
Monkeypox Vaccine: What You Need to Know {#monkeypox-vaccine-what-you-need-to-know}
There are two main vaccines available for monkeypox:
- JYNNEOS (MVA-BN): This is a newer vaccine that is approved for the prevention of both smallpox and monkeypox. It is a live, attenuated (weakened) virus vaccine and is considered safer than older smallpox vaccines.
- ACAM2000: This is an older smallpox vaccine that can also provide protection against monkeypox. However, it is a live virus vaccine and carries a higher risk of side effects.
Who should get vaccinated?
Vaccination is recommended for:
- People who have been exposed to monkeypox.
- Healthcare workers and laboratory personnel who are at high risk of exposure.
- Men who have sex with men and have multiple sexual partners.
- Other individuals who are at increased risk of infection.
Consult with your healthcare provider to determine if vaccination is right for you.
The Global Impact of Monkeypox {#the-global-impact-of-monkeypox}
Monkeypox has historically been confined to certain regions of Africa. However, recent outbreaks have demonstrated its potential to spread globally. The global impact of monkeypox includes:
- Public health concerns: The emergence of monkeypox in non-endemic countries has raised concerns about its potential to become a widespread global health threat.
- Economic impact: Outbreaks can disrupt travel, trade, and healthcare systems.
- Social impact: Stigma and discrimination can affect individuals and communities affected by monkeypox.
International collaboration and coordinated efforts are essential for controlling the spread of monkeypox and mitigating its global impact.
