Influenza (the flu) is an infection of the respiratory tract. The tract is made up of your mouth, nose, and lungs, and the passages between them. The flu can make a pregnant woman very ill. This is because changes that occur during pregnancy to the immune system, heart, and lungs make a pregnant women more likely to develop flu complications. These complications include sinus infections and serious lung infections such as bronchitis and pneumonia. The flu can cause high fevers which, during pregnancy, can cause birth defects and other complications in the developing fetus. In rare cases, the flu can lead to miscarriage of the baby or even death of the mother. This sheet tells you more about the flu, what to do if you get the flu, and what you can do to avoid infection.
Anyone can get the flu. But you are more likely to catch the flu if you:
Are often around young children
Work in a healthcare setting where you may be exposed to flu germs
Live or work with someone who has the flu
Haven’t had an annual flu shot
The flu is caused by a virus. The virus spreads through the air in droplets when someone who has the flu coughs, sneezes, laughs, or talks. You can become infected when you inhale the germ directly. You can also become infected when you touch a surface on which the droplets have landed and then touch your eyes, nose, or mouth. Touching used tissues, or sharing utensils, drinking glasses, or a toothbrush with an infected person can expose you to the flu germ, too.
Flu symptoms tend to come on quickly and may last a few days to a few weeks. They include:
Fever that's usually higher than 100.4°F (38°C) and chills
Sore throat and headache
Tiredness and weakness
Body and muscle aches
Here are some suggestions:
Call your healthcare provider right away. Follow any instructions your healthcare provider gives you.
You may be asked to get tested to confirm that you have the flu.
Your healthcare provider may prescribe medicines called antivirals. These medicines must be taken within 2 days of when your symptoms started. In some cases, your healthcare provider may not wait for test results to come back before starting you on antivirals. These medicines work by stopping the flu virus from reproducing in your body. This gives your body’s immune system a chance to fight the virus. After taking the medicine, your symptoms may be milder and you may recover quicker than without the medicine. The medicine may also prevent serious complications, like pneumonia.
If you feel you need medicines to relieve symptoms, ask your healthcare provider which ones are safe for you to take.
Drink lots of fluids such as water, juice, and warm soup to prevent dehydration. A good rule is to drink enough so that you urinate your normal amount. Feeling dizzy or lightheaded most likely means you need to drink more fluid.
Get plenty of rest.
If you aren't hungry, eat smaller meals more often during the day to make sure you get enough calories.
If you don't have a fever, put warm compresses on your forehead or sinuses to relieve congestion.
Call your healthcare provider if you become short of breath.
Get vaccinated. One of the best ways to avoid the flu is to get a flu shot. Pregnant women can safely get a flu shot. But pregnant women should not get the nasal spray vaccine for the flu. This is a live-virus vaccine and may be harmful to the baby. The nasal spray is not recommended for anyone for the 2017-2018 flu season. The CDC says the nasal spray did not seem to protect against the flu over the last several flu seasons.
Wash your hands often. Frequent handwashing is a proven way to prevent infection. Carry an alcohol-based hand gel containing at least 60% alcohol. Use it when you don’t have access to soap and water.
Clean items you use often with disinfectant wipes. This includes phones, computer keyboards, and toys.
Avoid crowds and children as much as possible while you are pregnant. Stay away from anyone who has the flu.
Handwashing is one of the best ways to prevent many common infections. Follow these steps for more effective handwashing:
Use warm water and plenty of soap. Work up a good lather.
Clean the whole hand, under your nails, between your fingers, and up the wrists.
Wash for at least 20 seconds. Don’t just wipe—scrub well.
Rinse, letting the water run down your fingers, not up your wrists.
Dry your hands well. Use a paper towel to turn off the faucet and open the door.
Alcohol-based hand gels are also a good choice for cleaning your hands. Use them when you don’t have access to soap and water, or your hands don't look dirty. Follow these steps:
Squeeze about a tablespoon of gel into the palm of one hand.
Rub your hands together briskly, cleaning the backs of your hands, the palms, between your fingers, and up the wrists.
Rub until the gel is gone and your hands are completely dry.
