Report on the WFH Annual Global Survey 2020

In the report on the Annual Global Survey 2020, there were a total of 120 data respondents who provided demographic and treatment information on people with bleeding disorders (PWBD). This report illustrates that globally over time, there have been over 393,000 PWBD identified and reported. Furthermore, new tables have been added to show the number of patients being treated with FVIIIa and FEIBA, as well as products used to treat VWD. The WFH is appreciative of all the efforts our national member organizations (NMOs) made in gathering this important data..
