Pregnancy, Flu, and Vaccination.
Did you know that the flu is more severe during pregnancy, increasing risks of hospitalization, premature labor, and fetal complications due to immune system changes?
Key symptoms include fever, cough, fatigue, and body aches. Vaccination (flu shot) is highly recommended for protection, and antiviral treatments are safe and encouraged if contracted.
Key Information on Flu and Pregnancy
• Risks to Mother & Baby: Pregnant women are more prone to severe illness, pneumonia, and hospitalization, especially in the second and third trimesters. Fever, a common symptom, can cause neural tube defects, particularly in early pregnancy. The virus increases risks of miscarriage, premature labor, and low birth weight.
• Symptoms: Symptoms are similar to those in non-pregnant individuals but may hit harder: fever (often higher than 100.4F), chills, cough, sore throat, runny nose, fatigue, headache, and muscle aches.
• Treatment: If symptoms occur, contact your healthcare provider immediately. Antiviral medications (e.g., Tamiflu) are safe during pregnancy and most effective when started within 48 hours. Acetaminophen is often recommended to manage fever.
• Prevention: The inactivated flu shot is recommended for pregnant women at any stage. The nasal spray vaccine is not recommended. Prevention also includes frequent handwashing and avoiding close contact with sick people.
• Postpartum: The risk of complications remains elevated for up to two weeks after giving birth.
When to Seek Emergency Care
Seek immediate medical attention if you experience difficulty breathing, chest pain, dizziness, severe vomiting, decreased fetal movement, or a high fever that does not respond to medication.
