vivax (uncountable)

  1. (medicine) Malaria caused by the parasite Plasmodium vivax.
    • 2009, Eli Schwartz, Tropical Diseases in Travelers, page 225:
      Thus, the usefulness of chloroquine or other blood stage prophylaxis in complete prevention of vivax is very limited (it might have some value only in areas where the relapse rate is very low), and it should not be regarded as a vivax prophylaxis.
