Abstract

Seven relapses of Plasmodium vivax or Plasmodium ovale despite standard treatment with primaquine (3.0 mg Kg-1) daily for fourteen days are presented. The majority of patients came from areas outside the countries where resistance to primaquine is well known. The various possibilities of reasons for relapses are discussed.
