Monkeypox: Symptoms, Treatment, Prevention, and Latest Updates

Table of Contents

What is Monkeypox?

Monkeypox is a viral disease that belongs to the orthopoxvirus family, which also includes smallpox. While less deadly than smallpox, monkeypox can still cause significant illness. It was first discovered in 1958 in laboratory monkeys, hence the name. The first human case was recorded in 1970 in the Democratic Republic of Congo. Since then, monkeypox has primarily occurred in Central and West Africa, but recent global outbreaks have raised international concern.

Understanding Monkeypox Origins

Historically, monkeypox has been endemic in certain parts of Africa. The virus is believed to circulate among various animal reservoirs, primarily rodents, which then transmit it to humans. Understanding these animal reservoirs is crucial for preventing future outbreaks.

Monkeypox Symptoms: What to Look For

The symptoms of monkeypox are similar to those of smallpox, but generally milder. The incubation period (the time from infection to the appearance of symptoms) is typically 7-14 days, but can range from 5-21 days. Common symptoms include:

• Fever
• Headache
• Muscle aches
• Backache
• Swollen lymph nodes (lymphadenopathy) – a key differentiator from chickenpox and other similar diseases.
• Exhaustion
• Rash: The rash usually appears 1-3 days after the onset of fever. It starts as flat, red bumps that turn into blisters filled with fluid. These blisters eventually scab over and fall off. The rash can appear on the face, hands, feet, mouth, or genitals.

The severity of monkeypox symptoms can vary from person to person. Some individuals may experience only mild symptoms, while others may develop a more severe illness.

How Does Monkeypox Spread?

Monkeypox can spread in several ways:

• Animal-to-human transmission: Through direct contact with an infected animal’s blood, bodily fluids, or lesions. Handling wild animals or consuming undercooked meat from infected animals can also lead to transmission.
• Human-to-human transmission: Through close contact with an infected person’s respiratory secretions, skin lesions, or contaminated materials (such as bedding or clothing). This includes:
• Direct contact with the rash or scabs
• Prolonged face-to-face contact (via respiratory droplets)
• Contact with contaminated items
• Mother-to-fetus transmission: Monkeypox can spread from a pregnant woman to her fetus through the placenta.

It’s important to note that monkeypox is not as easily spread as some other viruses, such as the common cold or influenza. Close, sustained contact is generally required for transmission. However, with the recent global outbreaks, public health officials are emphasizing the importance of taking precautions to prevent further spread.

Monkeypox vs. Chickenpox: Key Differences

Because both monkeypox and chickenpox cause a rash, they can sometimes be confused. However, there are several key differences:

• Lymphadenopathy: Swollen lymph nodes are a characteristic symptom of monkeypox, but are not typically present in chickenpox.
• Rash progression: The monkeypox rash progresses through distinct stages (macules, papules, vesicles, pustules, scabs) and the lesions tend to be similar in appearance across the body. Chickenpox lesions appear in crops, with lesions at different stages of development present simultaneously.
• Illness severity: Monkeypox is generally a more severe illness than chickenpox, with a higher risk of complications.
• Underlying virus: Monkeypox is caused by the monkeypox virus, while chickenpox is caused by the varicella-zoster virus.

If you are unsure whether you have monkeypox or chickenpox, it is essential to consult a healthcare professional for proper diagnosis.

Diagnosing Monkeypox: Tests and Procedures

Diagnosing monkeypox involves several steps:

• Clinical evaluation: A healthcare provider will assess your symptoms and medical history.
• Laboratory testing: A sample from a skin lesion (e.g., fluid from a vesicle or pustule, or a scab) is collected and sent to a laboratory for testing. The preferred test is a polymerase chain reaction (PCR) assay, which detects the monkeypox virus DNA.
• Other tests: Additional tests may be performed to rule out other conditions that can cause similar symptoms.

A confirmed diagnosis of monkeypox requires a positive laboratory test result.

Monkeypox Treatment Options: Current Strategies

Most people with monkeypox recover on their own without specific treatment. However, antiviral medications may be used in severe cases or in people who are at high risk of complications. Treatment strategies include:

• Supportive care: This includes rest, hydration, and pain relief. Over-the-counter medications like acetaminophen or ibuprofen can help manage fever and muscle aches.
• Antiviral medications: Tecovirimat (TPOXX) is an antiviral drug approved for the treatment of smallpox that has also been used to treat monkeypox in some cases. Brincidofovir (CMX001) is another antiviral medication that may be considered. These drugs work by inhibiting the virus’s ability to replicate.
• Vaccination: The smallpox vaccine can also provide protection against monkeypox, especially if given shortly after exposure.

The choice of treatment will depend on the severity of the illness and the individual’s overall health status. It’s crucial to consult a healthcare professional for guidance on the most appropriate treatment plan.

Monkeypox Prevention: Protecting Yourself and Others

Preventing monkeypox involves taking steps to reduce the risk of exposure:

• Avoid contact with infected animals: Especially rodents and primates, and avoid handling wild animals or consuming undercooked meat from infected animals.
• Practice good hygiene: Wash your hands frequently with soap and water, especially after contact with animals or infected people.
• Avoid contact with infected people: If you know someone who has monkeypox, avoid close contact with them, including touching their skin lesions or sharing personal items.
• Wear a mask: When in close contact with someone who has monkeypox, wear a mask that covers your mouth and nose.
• Clean and disinfect: Regularly clean and disinfect surfaces that may be contaminated with the monkeypox virus.
• Vaccination: Consider getting vaccinated against smallpox, which can also provide protection against monkeypox.

Monkeypox Vaccine: Availability and Efficacy

The smallpox vaccine can provide cross-protection against monkeypox. There are two main types of smallpox vaccines:

• ACAM2000: A live virus vaccine that is administered by pricking the skin. It can have more side effects than the newer vaccine.
• JYNNEOS (MVA-BN): A newer, non-replicating vaccine that is considered safer than ACAM2000. It is given as two doses, four weeks apart.

Vaccination is recommended for people who are at high risk of exposure to monkeypox, such as:

• Laboratory workers who handle orthopoxviruses
• Healthcare workers who care for patients with monkeypox
• People who have had close contact with someone who has monkeypox
• Individuals at high risk through sexual contact.

The vaccines are highly effective at preventing monkeypox, especially when administered before exposure. However, vaccination after exposure can also help reduce the severity of the illness.

Global Monkeypox Outbreak: Current Status and Trends

Since May 2022, a global outbreak of monkeypox has been ongoing, with cases reported in numerous countries that are not typically affected by the virus. This outbreak has raised concerns among public health officials worldwide. The World Health Organization (WHO) has declared the outbreak a public health emergency of international concern.

The majority of cases in the current outbreak have been reported among men who have sex with men. However, monkeypox can affect anyone, regardless of sexual orientation or gender identity.

Public health agencies are working to track the spread of the virus, identify cases, and implement control measures, such as vaccination and contact tracing.

Monkeypox and Pets: Risks and Precautions

There is a risk of monkeypox transmission between humans and animals, particularly pets. If you have monkeypox, it’s important to take precautions to protect your pets:

• Isolate yourself from your pets: Avoid close contact with your pets, including cuddling, kissing, or sharing bedding.
• Have someone else care for your pets: If possible, have a healthy person care for your pets while you are sick.
• Wash your hands: Wash your hands frequently with soap and water before and after interacting with your pets.
• Clean and disinfect: Clean and disinfect surfaces that your pets may come into contact with.

If your pet develops symptoms of monkeypox (e.g., rash, lethargy), consult a veterinarian immediately.

Long-Term Effects of Monkeypox

While most people recover fully from monkeypox, some may experience long-term effects:

• Scarring: The rash can leave permanent scars, especially if the lesions are deep or become infected.
• Vision problems: If the rash affects the eyes, it can lead to vision problems.
• Pain: Some people may experience chronic pain after recovering from monkeypox.
• Mental health issues: The stress and isolation associated with having monkeypox can lead to anxiety, depression, or other mental health issues.

More research is needed to fully understand the long-term effects of monkeypox. People who have had monkeypox should continue to monitor their health and seek medical attention if they experience any persistent symptoms.

Staying Informed: Reliable Monkeypox Resources

It’s important to stay informed about monkeypox from reliable sources:

• World Health Organization (WHO): The WHO provides up-to-date information on the global monkeypox outbreak.
• Centers for Disease Control and Prevention (CDC): The CDC offers information on monkeypox symptoms, prevention, and treatment.
• Your local health department: Your local health department can provide information on monkeypox cases in your area and local resources.

Avoid relying on unverified sources or social media for information about monkeypox.
