Chickenpox, also known as varicella, is a viral infection characterized by an itchy rash that appears as small red spots or blisters. Before the rash develops, individuals often experience symptoms such as fever and body aches. While chickenpox is typically contracted during childhood, some adults may remain susceptible if they have never had the virus. Fortunately, around 95% of women of childbearing age are immune to chickenpox.
Who Is at Risk During Pregnancy?
If you’ve previously had chickenpox, you are likely immune. However, if you are pregnant and have never contracted the virus, you could be at risk. It’s advisable to avoid anyone who has chickenpox. If you’re uncertain about your immunity, a simple blood test can determine if you have the necessary antibodies. If the test is positive, congratulations—you’re immune!
How Might Chickenpox Affect Your Baby?
The impact of chickenpox on your baby largely depends on the timing of the infection during your pregnancy. According to the Organization for Teratology Information Service (OTIS):
- First Trimester: If you contract chickenpox during this period, there is a 0.5-1% chance of birth defects.
- Weeks 13 to 20: The risk increases to about 2%.
- Delivery Window: If chickenpox occurs within five days before or one to two days after delivery, there is a 20-25% chance your baby may develop congenital varicella.
In cases where chickenpox occurs just before delivery, your baby might receive some of your antibodies, potentially resulting in a milder form of the disease. Possible birth defects associated with chickenpox include scarring, vision problems, growth issues, and developmental delays.
Protecting Your Baby
If you’ve had chickenpox before, you don’t need to take additional precautions, as your antibodies will protect both you and your baby. However, if you have never had chickenpox and are pregnant, you may be given a shot of zoster immune globulin (ZIG) after exposure to someone with chickenpox. This treatment must be administered within four days of exposure.
For those who haven’t had chickenpox, getting vaccinated is an option—but it’s essential to wait at least three months after vaccination before trying to conceive.
Can You Get Chickenpox More Than Once?
While it’s rare to contract chickenpox twice, individuals with compromised immune systems are at greater risk. Additionally, some people may believe they’ve had chickenpox due to a different rash or infection.
