All are true about communicability of Mlaria, except -
Malaria is communicable as long as mature,ble gametocytes exist in the circulating blood in sufficient densoty.In vivax infections,gametocytes appear in bloos 4-5 days after the appearance of asexual parasites,in falciparum infections they do not appear until 10-20 days after the first appearance of asexual parasites.During the early stages of infection the density may exceed 1000 per cubic mm of blood.Ref.PARK'S TEXTBOOK OF PREVENTIVE AND SOCIAL MEDICINE 21st edition page no 235.
The number of gametocytes in blood increases
Gametocytes appear in blood 4-5 days after the appearance of the asexual parasite, in vivax infection
Gametocytes appear in blood 10-12 days after the appearance of the asexual parasite, in falciparum infection
In the early stage of infection, their density may exceed 1000 per cmm of blood
