Data is representative. Data came from Program Data from Perinatal HIV intervention Monitoring System (PHIMS) which records information related pregnant women receiving health services including syphilis screening and treatment from both a majority of government health facilities and some of private health facilities. Through PHIMS, all pregnant women should receive VDRL screening at first or any ANC visit. But the coverage was not 100% probably due to 1) Incomplete data record, 2) No lab record as this data was reported by delivery sites among the first ANC from different delivery hospitals.
