[Cytomegalovirus detoxification and associated factors among preschool children in Yi'nan County].

Objective

To investigate cytomegalovirus detoxification and associated factors among preschool children in Yinan County, Shandong Province.

Methods

Two kindergartens were selected from the county and township of Yinan respectively. A total of 250 children were investigated in October 2018. Case information was obtained through the child's guardian. Saliva samples of children and their mothers were collected for cytomegalovirus realtime-PCR detection.The status of CMV detoxification of children was explored and the associated factors were analyzed.

Results

A total of 242 preschool children were investigated, and the detoxification rate of cytomegalovirus among them was 22.31% (54/242, 95%CI: 17.0%-27.6%). Logistic regression analysis showed that the rate of detoxification was higher in children whose mothers were cytomegalovirus detoxified (OR=12.39, 95%CI:1.73-88.65)and whose school was located in the county (OR=3.58, 95%CI:1.34-9.55).

Conclusions

The detoxification rate of cytomegalovirus in preschool children is high, and there is mutual transmission between children and mothers. Women of childbearing age should pay attention to prevent congenital cytomegalovirus infection when they come into contact with children.
