How do people get afflicted with malaria?

Four species of parasites cause malaria in man. The most dangerous of these is the plasmodium falciparum that can cause cerebral malaria. This species afflicts about one-tenth of total malaria victims and might even prove fatal. The parasite enters the body by the bite of the female anopheles mosquito, which is the only mosquito type that transmits human malaria. You cannot catch malaria directly from another human being - the infecting parasite has to pass through a mosquito first. Even if a mosquito that has bitten a malarial patient bites you, the transmitted as malaria parasite has an incubation period in mosquitoes, just as it has in human beings.

Four species cause human malaria.

P. Falciparum

P. Vivax

P. Malariae

P. Ovale

Life cycle of the malarial parasite

  1. Sporozoites in salivary gland
  2. Oocysts in stomach wall
  3. Male and female Gametocytes
  4. Liver phase
  5. Release of merozoites from liver

These enter red cells where both sexual and asexual cycle continue.

can we have a anti virus for dengu

Mosquitoes are the number one enemy of public health because they are vectors of a lot of diseases such as malaria and dengue. That's why it is really important that we eradicate them. Numerous studies have been done against mosquitoes. There are insecticides and organic insecticides to kill them.

If mosquitoes can carry and transmit a virus the size of the Malaria virus, why do they not also carry and transmit a much smaller virus called HIV? Medicos poo poo this idea. If the insects don't transmit and carry Aids then should the filtering mechanism be closely studied?

ParasiteRex

First off malaria is a parasite, not a virus. The parasite goes developmental stages within the mosquitos gut. The parasite migrates to the mouthparts of the mosquito to be spread to another person. Viruses don't do this.
