Abstract
Objectives To determine the seroprevalence of cytomegalovirus in pregnant women and to identify those with acute or reactivated infections. Materials and methods The seroprevalence of IgG and IgM antibodies in 323 pregnant women in the Maternity Hospital of Goiânia was studied using ELISA. Seventy-seven samples were randomly selected to undergo the IgG avidity test for the serological stage without IgM. Results The mean ± SD age was 24.55 ± 6.80 years and the mean ± SD gestational age was 23.09 ± 8.78 weeks. IgG antibodies were identified in 98.76% and IgM antibodies in 0.62%. Low avidity was found in 31.17% and high avidity was found in 68.83%. Conclusions Among the pregnant women studied, 98.76% had chronic infection and 0.62% had acute infection. The results of the IgG avidity test revealed that 31.17% were in the acute stage of cytomegalovirus infection. This finding highlights the need for more sensitive detection methods in the acute phase, due to the greater possibility of congenital infection.
