If a pregnant woman is infected with influenza B virus at 7 months of gestation, the virus may cross the placenta and enter the fetal body, affecting fetal growth and development. The infection may cause symptoms such as fever, headache, and fatigue in the pregnant woman. If serious complications such as pneumonia or myocarditis develop following influenza B infection, they may have a greater impact on fetal development and could even lead to fetal death. Pregnant women who become infected with influenza B virus at 7 months of pregnancy should seek prompt medical attention and receive appropriate treatment to minimize adverse effects on the fetus.
