Let’s be real. Pregnancy is hard enough without worrying about every little germ. But your immune system changes when you’re pregnant. That makes you more vulnerable to infections. The good news? Most are preventable or treatable. Here’s what you need to know.
Urinary Tract Infections (UTIs)
You’re more likely to get a UTI when you’re pregnant. Your growing baby presses on your bladder. Urine doesn’t flow as well. Bacteria love that.
Watch for: Burning when you pee. Running to the bathroom constantly. Cloudy or smelly urine.
What helps: Your doctor can give you safe antibiotics. Drink lots of water. Don’t hold your pee in. Left untreated, a UTI can trigger early labor. So don’t ignore it.
GBS
This one sounds scary. But here’s the truth. About 1 in 4 women carry GBS naturally. It doesn’t hurt you at all. But during vaginal delivery, your baby can pick it up. That can make your baby very sick.
The fix: You’ll get a quick swab at 36–37 weeks. That’s it. If you’re positive, you get IV antibiotics during labor. Problem solved.
Cytomegalovirus (CMV)
You’ve probably never heard of it. Most adults haven’t. It’s a common virus. No big deal for you. But if you catch it for the first time while pregnant? That can cause hearing loss or delays for your baby.
How to avoid it: Tiny kids spread it like crazy. Don’t share food or utensils with them. Don’t kiss them on the lips. Wash your hands after changing diapers. Simple stuff.
Toxoplasmosis
Cat lovers, don’t panic. You don’t need to give away your pet. But there’s a parasite in cat poop. Also in undercooked meat and unwashed veggies.
The risk: It can cross to your baby and cause eye or brain problems.
What to do: Have someone else clean the litter box. Cook meat until it’s well done. Wash your produce. Wear gloves for gardening. That’s really it.
Listeriosis
This one is sneaky. You might just feel a little flu-ish. But for your baby? It can cause miscarriage or stillbirth.
Where it hides: Soft cheeses like brie or feta (unless pasteurized). Deli turkey and ham. Hot dogs. Leftovers you don’t reheat well.
The rule: Heat deli meats until they steam. Skip the fancy unpasteurized cheese. When in doubt, don’t eat it.
STIs (Chlamydia, Gonorrhea, Syphilis, HIV, etc.)
Awkward topic. But necessary. These infections can cause early labor or pass to your baby during delivery.
The good news: Your doctor will test you early in pregnancy. Most bacterial STIs are curable with safe antibiotics. HIV and hepatitis B can be managed so your baby stays healthy.
Don’t skip the test just because it’s uncomfortable. It protects your baby.
Flu and COVID-19
You get sicker from these when you’re pregnant. It’s just a fact. A high fever in early pregnancy can also affect your baby’s development.
The bottom line: Get the flu shot. Get the COVID vaccine. Both are safe any trimester. If you get sick, call your doctor right away. Antiviral meds can help.
A Few Simple Rules to Stay Safe
· Wash your hands. Especially after touching kids, raw meat, or animals.
· Don’t eat raw or undercooked meat.
· Skip unpasteurized dairy.
· Get your vaccines.
· Go to your prenatal appointments.
Call Your Doctor Right Away If:
· You have a fever over 100.4°F (38°C).
· It hurts to pee.
· You have a bad headache with a stiff neck.
· You notice a rash.
· Your baby isn’t moving as much (after 28 weeks).
Final Thoughts
You don’t need to live in a bubble. Most pregnant women never have a serious infection. But knowing the risks gives you power. A few small habits — washing your hands, heating your deli meat, skipping the litter box — can make all the difference.
Trust your gut. If something feels off, call your provider. You’ve got this.
