| 0:00.0 | Malaria is an infectious disease caused by single-celled microorganisms called plasmodiums. |
| 0:22.6 | These microorganisms are parasites that live inside mosquitoes. |
| 0:27.6 | In particular, the Anopheles mosquito genus, of which there are about 460 species, |
| 0:35.6 | 100 of which are known to be transmitters of malaria, though fewer than half of that |
| 0:41.3 | number are common transmitters of this parasite. |
| 0:45.9 | Because female mosquitoes are the ones that bite, they are the ones that transmit their |
| 0:51.0 | plasmodium parasite to other species. |
| 0:59.8 | And the Enopheles, Gambi, is one of the most well-known of this mosquito genus, |
| 1:03.9 | because it sometimes carries the plasmodium-phalsyperum parasite, |
| 1:10.5 | which is the most dangerous and deadly when transmitted to humans through these mosquito's saliva, which is transmitted, |
| 1:12.3 | by the way, because mosquito saliva has special properties that keeps blood from clotting. |
| 1:18.7 | So they jab their human prey with their proboscis, inject a little saliva into the blood, |
| 1:25.8 | which keeps it from clotting so they can drink their fill |
| 1:28.4 | before the wound starts sealing itself up. And that is how the parasite is transmitted from |
| 1:34.3 | mosquito to human. These little transmitted parasites, once inside a human host, circulate through |
| 1:42.0 | the bloodstream, eventually reaching the liver and setting up |
| 1:45.5 | shop, reproducing wildly, and in turn, beginning an infection process that does not |
| 1:52.4 | manifest any symptoms for somewhere between 8 and 30 days, on average. |
| 1:59.1 | After that asymptomatic period, the now multitudinous microorganisms |
| 2:03.5 | rupture the liver cells they've been hiding and reproducing in and shoot out toward the |
| 2:10.5 | human host's red blood cells, which is the beginning of a new stage of this organism's |
| 2:16.4 | life cycle. It generally makes it to this next stage |
