Shingles is a viral infection that can be quite painful. It’s caused by the same virus that causes chickenpox, the varicella-zoster virus. A common concern for pregnant women is whether they can catch shingles and what the effects might be on their pregnancy. This article will explain how shingles spreads, whether it can be contagious to pregnant women, and what precautions you should take.
What is Shingles?
Shingles, also known as herpes zoster, is a reactivation of the varicella-zoster virus that lies dormant in the body after a person has had chickenpox. The virus can reactivate years later, causing a painful rash, usually on one side of the body. The rash often forms a band of blisters that crust over after a few days. Shingles is most common in older adults, but it can affect people of all ages, especially those with weakened immune systems.
How is Shingles Spread?
Shingles is not as easily spread as chickenpox, but it is still contagious. The virus spreads through direct contact with the fluid from the blisters that appear on the skin. This means that if a person with shingles touches their rash and then touches another person, the virus can spread to that person. It’s important to note that someone who has never had chickenpox or hasn’t been vaccinated for chickenpox can develop chickenpox from exposure to the shingles rash. After the person gets chickenpox, they may later develop shingles.
The virus is not spread through coughing, sneezing, or casual contact. It requires direct contact with the fluid from the blisters. Once the rash has crusted over, the person is no longer contagious.
Is Shingles Contagious to Pregnant Women?
If you are pregnant and come into contact with someone who has shingles, there are some important factors to consider. The main concern is whether you have had chickenpox or been vaccinated against it in the past. If you’ve had chickenpox, you’re already immune to the varicella-zoster virus, which means you won’t catch it again in the form of chickenpox or shingles.
However, if you have never had chickenpox and have not received the chickenpox vaccine, you are at risk of developing chickenpox if exposed to shingles. The risk to a pregnant woman primarily comes from developing chickenpox, which can have serious consequences for both the mother and the baby.
The Risk of Shingles to a Pregnant Woman Who Has Never Had Chickenpox
If a pregnant woman has never had chickenpox, she is susceptible to catching the varicella-zoster virus if exposed to shingles. If this happens, she will develop chickenpox, not shingles. It is essential to understand that chickenpox can cause severe complications for pregnant women and their unborn babies.
Risks to the Mother
For a pregnant woman, chickenpox during pregnancy can lead to several health problems. The most common complications include:
Pneumonia: Chickenpox can lead to viral pneumonia, which can be severe and require hospitalization.
Secondary bacterial infections: The rash and blisters caused by chickenpox can become infected with bacteria, leading to additional complications.
Encephalitis: In rare cases, chickenpox can cause inflammation of the brain (encephalitis), which can be life-threatening.
Risks to the Baby
If a pregnant woman contracts chickenpox during the first 20 weeks of pregnancy, it can affect the unborn baby. The risks include:
Congenital varicella syndrome: This rare condition can cause birth defects such as limb abnormalities, eye problems, and brain damage.
Premature birth: Chickenpox during pregnancy can lead to premature delivery.
Low birth weight: Babies born to mothers with chickenpox may have a lower birth weight.
Neonatal varicella: If a mother develops chickenpox close to delivery, the baby may be born with chickenpox, which can be severe and even life-threatening.
The risk to the baby is highest when the mother contracts chickenpox during the first or second trimester of pregnancy.
The Risk of Shingles to a Pregnant Woman Who Has Had Chickenpox
If you’ve had chickenpox in the past, you are already immune to the varicella-zoster virus. In this case, the risk of catching shingles from someone who has shingles is extremely low. You will not develop chickenpox or shingles again.
However, it’s still important to take precautions. Even though you are immune to the varicella-zoster virus, there is still a very small chance you could develop shingles yourself later in life. In most cases, having had chickenpox provides lifelong immunity against the virus, but it can reactivate under certain conditions, such as stress or a weakened immune system.
What Are the Precautions a Pregnant Woman Should Take?
If you are pregnant and come into contact with someone who has shingles, there are a few precautions you should take to reduce the risk of developing chickenpox:
Avoid direct contact with the rash: The most important precaution is to avoid touching or coming into contact with the shingles rash. If you’re around someone with shingles, try to maintain a safe distance and avoid touching the rash or any objects that might have been contaminated by it.
Wash your hands frequently: Regular handwashing can help reduce the chance of transferring the virus to your body if you touch an infected surface. Make sure to wash your hands thoroughly with soap and water, especially after being in close contact with someone with shingles.
Consult your doctor: If you’re pregnant and have been exposed to shingles, contact your healthcare provider. Your doctor may want to test you to see if you have immunity to chickenpox. If you’re unsure whether you’ve had chickenpox or received the chickenpox vaccine, it’s better to be cautious and consult your doctor for advice.
Get vaccinated if you’re planning a pregnancy: If you have never had chickenpox and are planning to become pregnant, consider getting the chickenpox vaccine before conception. This can help protect you from getting chickenpox during pregnancy. However, if you are already pregnant, you should not get the chickenpox vaccine.
What Should You Do if You Think You Have Been Exposed to Shingles?
If you think you’ve been exposed to shingles and are pregnant, take the following steps:
Monitor for symptoms: Watch for symptoms of chickenpox, such as a fever, tiredness, and a rash that starts as red spots and turns into blisters. If you develop these symptoms, seek medical attention immediately.
Visit your doctor: If you’ve had exposure to shingles, your doctor may recommend a blood test to determine if you’ve had chickenpox in the past. If you haven’t had chickenpox, your doctor might consider antiviral treatment to help reduce the risk of complications.
Consider treatment: If you develop chickenpox during pregnancy, antiviral medications may be prescribed. These medications can help lessen the severity and duration of the illness, though they are most effective if started early. In some cases, intravenous immunoglobulin (IVIG) may be recommended to help protect the baby.
Conclusion
Shingles can be contagious, but the risk to a pregnant woman depends largely on whether she has had chickenpox before. If you’ve had chickenpox, you are immune to the varicella-zoster virus and should not catch shingles. However, if you have never had chickenpox, you are at risk of catching the virus and developing chickenpox if exposed to shingles. Chickenpox during pregnancy can be dangerous for both the mother and the baby, so it’s important to take steps to avoid exposure and seek medical advice if you think you’ve been exposed.
By being aware of the risks and following the necessary precautions, pregnant women can reduce the chances of complications from shingles and protect their health and the health of their babies. Always consult with your healthcare provider for the best course of action if you are concerned about exposure to shingles during pregnancy.
