a. <4 weeks
b. 13 to 16 weeks
c. > 16 weeks
d. Rubella infection during pregnancy is extremely rare

Answer 1

The risk of rubella infection during pregnancy depends on the timing of maternal infection. Infections before 11 weeks carry a high risk of complications, while infections between weeks 13-16 have a 35% risk. After 16 weeks, the risk is low.

Step-by-step explanation:

The risk of rubella infection during pregnancy varies based on the timing of maternal infection. If a pregnant woman is infected with rubella before 11 weeks of pregnancy, there is a high incidence of stillbirth, spontaneous abortion, or congenital birth defects. Between weeks 13-16, the risk is 35%. After 16 weeks, the risk is low. Therefore, it is important for pregnant women to avoid rubella infection, and prenatal screening for rubella is commonly practiced.
