All of the following statements are true about congenital rubella except:
Ans. is 'd' i.e., Infection after 16 weeks of gestation results in major congenital defects(Ref: Harrison, 18th/e, p. 1606; 19th/e, p. 1300)* The most important factor in the pathogenicity of Rubella virus for the fetus is gestational age at the time of infection.* "In general, the earlier in pregnancy infection occurs, the greater the damage to the fetus. Maximum damage to the fetus occurs when infection acquired in the first trimester of pregnancy."* Risk of damage to fetus by maternal rubella during pregnancy.* Birth defects are uncommon if maternal infection occurs after the 20th week of gestation.
It is diagnosed when the infant has IgM antibodies at birth
It is diagnosed when IgG antibodies persist for more than 6 months
Most common congenital defects are deafness, cardiac malformation and cataract
Infection after 16 weeks of gestation results in major congenital defects
