  1. Anopheles mosquitos can live up to 6 weeks after ingesting gametocytes.
  2. Semi-immune individuals (visitors or recent immigrants) may have prolonged infection without overt symptoms and may not recover from malaria or die of malaria.
  3. P. falciparum gametocytes usually appear ~7-10 days after symptom onset, can last up to 10-22 days. Blood stage treatment does not kill P. falciparum mature gametocytes.
  4. P. vivax gametocytes can appear before symptom onset, during the prepatent period, and are killed with blood stage treatment.
