[Serological survey of cytomegalovirus infection in Guizhou].

From August to October 1987, 577 serum samples were examined for the presence of CMV-IgG antibody by using indirect ELISA in Guizhou. The positive rate of CMV antibody varied from 87.5 to 92.4% in three areas and from 80.9-94.9% in various ages groups. It was suggested that the main transmission route of CMV infection in early life might be transmitted from mothers to their infants, but there might be some close contact transmission in population. The results showed that CMV infection was common in Guizhou. It was necessary to study further the correlation between CMV infection and birth defects.
