Immunization Analysis and Insights
The Immunization Analysis & Insights Unit is a data hub and analytics engine for immunization data and performs analytics. The unit supports the work of other technical units within the department of Immunization, Vaccines and Biologicals (IVB) and drives innovation in data quality and use in countries. It also has responsibility for IVB’s global work on VPD surveillance and generating data and evidence on the public health and economic impact of vaccines.
Provisional monthly measles and rubella data
Description
Timely measles and rubella surveillance is critical to disease control. Identifying and confirming suspected measles and rubella cases through surveillance allows:
1) early detection of outbreaks,
2) analysis of on-going transmission in order
to mount more effective vaccination measures, and
3) estimation of the underlying true incidence based on the patterns in reported data.
Please note that the data are available on the WHO Immunization Data Portal - Provisional measles and rubella data
Most Member States submit monthly reports on suspected and confirmed measles and rubella cases identified through their national disease surveillance systems to WHO. In general, the number of reported cases reflects a small proportion of the true number of cases occurring in the community. Many cases do not seek health care or, if diagnosed, are not reported. In addition, there is a one to two month lag time in reporting. For these reasons, the data provided on this page under-represents the true number of cases, particularly those occurring in the last one to two months.
