Monkeypox and chickenpox are two different diseases caused by distinct viruses, yet they share some similarities. If you’ve had chickenpox in the past, you might wonder if it offers any protection against monkeypox. In this article, we will explore the differences between these two diseases, the potential for cross-immunity, and whether having chickenpox makes you less likely to catch monkeypox.
What Is Monkeypox?
Monkeypox is a viral disease that was first discovered in monkeys in 1958. It is caused by the monkeypox virus, which is related to the smallpox virus. Monkeypox is primarily found in certain parts of Africa, but it has spread to other regions in recent years, including the United States and Europe.
Monkeypox symptoms can be similar to smallpox, including fever, headache, muscle aches, and swollen lymph nodes. However, a defining characteristic of monkeypox is the appearance of a rash. This rash usually starts on the face and spreads to other parts of the body. The rash begins as flat spots, which then become raised and filled with fluid. The spots eventually turn into scabs and fall off as the infection heals.
What Is Chickenpox?
Chickenpox, also known as varicella, is a contagious disease caused by the varicella-zoster virus (VZV). It is most common in children, though adults can also get it if they have not been previously infected. Chickenpox is highly contagious and spreads through respiratory droplets or by direct contact with the fluid from the blisters of an infected person.
Symptoms of chickenpox include fever, fatigue, and an itchy rash that usually starts on the face, scalp, or torso. The rash consists of red spots that turn into fluid-filled blisters. These blisters eventually crust over and heal, typically within two weeks. Once someone recovers from chickenpox, the virus remains in the body in a dormant state and can reactivate later in life as shingles.
How Are Monkeypox and Chickenpox Different?
Although monkeypox and chickenpox have some similar symptoms, they are caused by different viruses. Here are some key differences:
Virus: Monkeypox is caused by the monkeypox virus, a member of the orthopoxvirus family, while chickenpox is caused by the varicella-zoster virus (VZV), a member of the herpesvirus family.
Transmission: Chickenpox spreads mainly through respiratory droplets and contact with the fluid from chickenpox blisters. Monkeypox, on the other hand, can spread through respiratory droplets, direct contact with bodily fluids, or contact with contaminated materials.
Rash: Both diseases cause rashes, but they look different. In chickenpox, the rash appears as red spots that develop into blisters and then scab over. In monkeypox, the rash starts as flat lesions that turn into raised bumps, which later form blisters, and eventually scab over.
Severity: Chickenpox is generally a mild disease in children, but it can be more serious in adults or people with weakened immune systems. Monkeypox can also be serious, with complications that can be fatal, particularly in people with compromised immune systems.
Can Having Chickenpox Provide Immunity Against Monkeypox?
Now, you may be wondering if having chickenpox in the past offers any protection against monkeypox. After all, both diseases involve a viral infection that causes a rash, and both viruses are part of the broader family of viruses that cause pox-like diseases.
However, despite these similarities, having chickenpox does not provide immunity against monkeypox. The two viruses are distinct and do not offer cross-protection. This means that even if you have had chickenpox, you are not immune to monkeypox. Each virus targets different parts of the immune system and requires a different type of immunity.
The Role of Immunity
When you recover from chickenpox, your body develops immunity to the varicella-zoster virus, meaning you are unlikely to get chickenpox again. However, this immunity does not extend to monkeypox, as the viruses involved are too different.
For protection against monkeypox, you would need immunity to the monkeypox virus itself. This immunity can be acquired in several ways:
Natural Infection: If you were to contract monkeypox, your immune system would develop a response to the virus, potentially offering protection against future infections.
Vaccination: There is a smallpox vaccine that has been shown to offer some protection against monkeypox. Since the monkeypox virus is closely related to the smallpox virus, the smallpox vaccine can help prevent infection with monkeypox. However, the smallpox vaccine is not routinely given today because smallpox has been eradicated.
Exposure to the Virus: If you come into contact with someone who has monkeypox, your immune system may respond by producing antibodies, helping to prevent the virus from spreading in your body.
Can You Catch Monkeypox If You’ve Had Chickenpox?
The simple answer is yes, you can still catch monkeypox even if you have had chickenpox in the past. As mentioned earlier, chickenpox and monkeypox are caused by different viruses, and immunity to one does not protect you from the other.
Although having chickenpox means you have immunity to the varicella-zoster virus, it does not mean your immune system is equipped to fight off the monkeypox virus. Therefore, if you’re exposed to the monkeypox virus, you could become infected.
How to Protect Yourself from Monkeypox
Since immunity from chickenpox does not offer protection against monkeypox, it is important to take steps to reduce your risk of catching the disease. Here are some ways to protect yourself:
Vaccination: While there is no specific vaccine for monkeypox in most countries, smallpox vaccination has been shown to offer some protection. If you’re at risk for monkeypox, you may want to discuss vaccination options with your healthcare provider.
Avoiding Contact with Infected Individuals: Monkeypox spreads through close contact with an infected person’s bodily fluids, lesions, or contaminated materials. Avoiding close contact with anyone who has monkeypox can significantly reduce your risk of catching the virus.
Good Hygiene Practices: Regular hand washing, using hand sanitizers, and avoiding touching your face can help prevent the spread of the monkeypox virus. It’s also essential to avoid touching any lesions or scabs if you or someone around you is infected.
Staying Informed: Keeping up with the latest information on monkeypox outbreaks and following public health guidelines can help you stay informed about the risks in your area.
Conclusion
In conclusion, having had chickenpox does not make you immune to monkeypox. Chickenpox and monkeypox are caused by different viruses, and immunity to one does not protect against the other. If you’ve had chickenpox, it is still possible to contract monkeypox if you’re exposed to the virus.
The best way to protect yourself from monkeypox is through vaccination, avoiding close contact with infected individuals, practicing good hygiene, and staying informed about any outbreaks. If you are concerned about your risk or have been exposed to monkeypox, it is always a good idea to consult with your healthcare provider for the best course of action.
