2	2	residence_over_5yr	residence	whole_country	continuous residence > 5 years	3 years	A former resident (>5 continuous years) of a country that has ANY malaria-endemic area is screened treating the entire country as endemic, and is deferred 3 years (FDA 12/2022 §IV.B.2). Residence is assessed by country, not by sub-national area. The Director of CBER did NOT authorize pathogen reduction as an alternative to this deferral, citing the higher residual risk and the fact that every reported U.S. TTM case implicated former residents of endemic countries or donors with a prior malaria diagnosis.
