how does this have to do with diseases and conditions?

How severe sickle cell is depends on genetics. Someone with severe sickle cell is likely to be unhealthy and die.\n\nHowever, light sickle cell anemia is actually very effective in inhibiting the malaria parasite. Because malaria is widespread in africa, this becomes a selection pressure. People with sickle cell  are more likely to survive malaria than people who don't, so there are many africans that have sickle cell - it's an evolutionary advantage.

Malaria is a mosquito borne disease caused by the protozoan Plasmodium.The life cycle of malarial parasite comprises 2 phases namely the asexual phase in human & sexual phase in the female anopheles mosquito(Definitive host).\n\nIn the asexual phase,the parasite undergoes asexual multiplication in the liver & blood. Man acts as the intermediate host. Initially when an infected mosquito bites,the plasmodium is introduced into the humanbody in the form of Sporozoites.The sporozoites pass into blood stream & after, abt 30 minutes they disappear from the blood & reach the liver parenchymal cells(hepatocytes).\n\nInside the liver cells,the sporozoites become rounded. Their nuclei undergo repeated divisions & daughter nuclei are surrounded by the cytoplasm.This stage,the parasite is called Schizont.\n\nThe schizonts burst & release the merozoites.The liberated merozoites then invade the RBCs to start the erythrocytic schizogony(multiple asexual reproduction).In the erythrocytes the merozoites passes thro' 1.Signet ring stage 2.Amoeboid stage 3.Rosette stage 4.Schizoint stage. This results in malarial fever.

No.  As for being partially resistant to malaria...there are shots for that to make you 100% resistent.

It is an island in the West Indies, Lesser islands (former British colony).\nCheck out the official site of the island.

yeah, sickle celled people are resistant to malaraia, so its thought to be a mutation that has helped people adapt to areas high in malaria like africa. so black people have it at a much higher rate than white people

The 2 alleles responsible for whether normal or sickle red blood cells are HbA and HbS. The HbS allele (sickle cell gene) is recessive but more exactly, that allele is incompletely recessive (i.e. in the heterozygote HbAHbS, a few sickle red blood cells are still present besides the normal one, shows that HbS gene are still expressed at small rate). The HbS induces the polymerization of hemoglobin in red blood cells, leading to abnormal sickle shape of the cells, making it very difficult for these red blood cells to pass through the blood vessels and stuck there.\n\nOne person is called suffering from sickle cell anemia if they have the HbSHbS form, i.e. the homozygous recessive. In the HbAHbS the few sickle red blood cells are not enough to cause symptoms. \n\nOne interesting thing about this disease is that, while the HbSHbS form would be dangerous because the red blood cells cannot carry oxygen to cells and stuck in the blood vessels, the carriers (HbAHbS) would have advantage in malaria region. Since the malaria parasite spends parts of its life in red blood cells, these parasite cause the abnormal sickle cells to rupture, moreover, the polymerization of Hb disables the parasites to digest Hb. The white blood cells also kill the parasite better when they come to kill the stuck sickle cells. That why people with HbAHbS form have a higher fitness to the malaria environment than people with normal red blood cells.

Is your mosquitoe ill?? I dont understand.

It's a new species of Plasmodium that was isolated from Malagasy birds of family Vangidae (vangas). The description was originally published in the Journal of Parasitology in 2005.
