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 received VDRL screening at first ANC visit but the coverage may be not 100% probably due to uncompleted data record.
