WHO compiles this data through its system of monitoring and reporting on global progress in countries' health sector responses toward universal access to HIV prevention, treatment, care and support.\u00a0 WHO, UNICEF, and UNAIDS provide joint support as a component of the Global HIV/AIDS Response Progress Report.\n\nM&E Framework\n\n    \n\nMethod of estimation of global and regional aggregates\nWeighted averages using number of live births as the weight.\n\nDisaggregation\n\n    \n\nUnit of Measure\nCases per 100 000 live births\n\nUnit Multiplier\n\n    \n\nExpected frequency of data dissemination\nAnnual\n\nExpected frequency of data collection\nAnnual\n\nLimitations\nDiagnosis of congenital syphilis is most reliable when using specific diagnostic tests that are seldom available even in developed countries.\u00a0 Therefore, in most countries diagnosis of congenital syphilis relies on clinical history and examination, making surveillance challenging.\u00a0 Although WHO has a global case definition for surveillance purposes, actual case definition may vary between and within countries and regions.\u00a0\u00a0 Given the difficulties in diagnosing congenital syphilis, and depending on the case definition used, either underreporting or overreporting can be a problem.\u00a0 The likely magnitude of such reporting errors should always be considered when looking at rates of congenital syphilis.\u00a0 However, with use of a consistent case definition, trends over time may be useful.\n\nLinks\nProgress report 2011: Global HIV/AIDS response (WHO, UNICEF, UNAIDS, 2011)\n\nLinks\nA guide on indicators for monitoring and reporting on the health sector response to HIV/AIDS (WHO, UNICEF, UNAIDS, 2012)\n\nLinks\nMethods for surveillance and monitoring of congenital syphilis elimination within existing systems (WHO, 2011)\n\nLinks\nGlobal guidance on criteria and processes for validation of elimination of mother-to-child transmission of HIV and syphilis\n\nComments\nIt is important that countries when reporting syphilis communicate on the extent to which the data are felt to be representative of the national population.\u00a0 If a country is unable to report on the denominator, WHO will use the denominator as per the UN Ppopulation Division.\n\nContact Person\n\n      \n\n",
