Report on the WFH Annual Global Survey 2019

The Report on the Annual Global Survey 2019 is now published and available online.

Despite the COVID-19 pandemic proposing many data collection challenges for our national member organizations (NMOs), a total of 115 countries responded to the questionnaire this year. The report includes data on over 324,000 people with bleeding disorders, provides information on patients with bleeding disorders, and shows the progress of hemophilia care using demographic and treatment information. Furthermore, the report uses the new hemophilia prevalence estimates to illustrate the inequities in patient diagnosis globally. The WFH is appreciative of all the efforts of our national member organizations (NMOs) in gathering the important data used for the WFH Annual Global Survey 2019.
