Which genetic disease is common in areas like Africa where malaria is a danger?
Sickle Cell Anemia
What is the origin of malaria?
Malaria is a disease that is more active in areas of Africa and Asia. The origin of malaria is through the bite of a mosquito.
Why is malaria more common in marshy areas?
Marshy areas are good places for mosquitoes to breed. Mosquito being the vector for malaria.
How many African Americans are carriers of the sickle cell disease?
Sickle-cell disease, usually presenting in childhood, occurs more commonly in people (or their descendants) from parts of tropical and sub-tropical regions where malaria is or was common. One-third of all indigenous inhabitants of Sub-Saharan Africa carry the gene, because in areas where malaria is common, there is a survival value in carrying only a single sickle-cell gene . Those with only one of the two alleles of the sickle-cell disease are more resistant to malaria, since the infestation of the malaria plasmodium is halted by the sickling of the cells which it infests. The prevalence of the disease in the United States is approximately 1 in 5,000, mostly affecting African Americans, according to the National Institutes of Health.
What population is affected by sickle cell disease?
Sickle cell generally affects those of African origin, more specifically those whose parents are from areas where malaria is common
Is there a vaccination for malaria?
No, there isn't. But there is a preventative medication one can take while in malaria-infested areas to keep the disease from taking hold even if one would get exposed to it.
How many worldwide cases of malaria occur each year?
Malaria is one of the most common diseases on earth, and affects 10% of the worlds population, with over 300,000 new cases each year. In addition, the complex life cycle of the apicomplexan Plasmodium (the causative agent of malaria) makes it difficult to develop a vaccine against the disease because it involves transmission between several hosts.
Why are red blood cells sickle shaped in a person with sickle cell disease?
Sickle cell is common in people from tropical areas where malaria is prevalent. Malaria can not survive on blood cells that are sickle shaped, so when populations were being killed off by malaria, those with sickle cell were surviving and passing on the sickle cell gene.
People say malaria is common disease with mosquitoes and you have been bitten a lot Are you just lucky you haven't gotten malaria?
Mosquitoes must bite an infected human and eat the infected human's blood, before that mosquito can then bite an uninfected human and transfer the disease. Malaria is common in some areas of the world but much less common in the USA, Canada, and eastern overseas countries like the UK, Ireland, Spain, etc. In the developed countries, we also have more access to medications to treat illness, as well as more access to chemicals to kill mosquitoes.
What sporozite protist causes malaria in tropical areas What sporozite protist causes malaria in tropical areas?
Plasmodium, which is transmitted by mosquitoes, causes malaria in tropical areas.
Why mosquito not affected by malaria?
Mosquitoes are not infected with malaria until they bite someone with the disease. The mosquito is then infected with a parasite and goes on to infect others. Malaria is prevalent in tropical and sub tropical areas and is a major cause of death in third world countries.
At what altitude would you get malaria?
You get malaria in areas where mosquitoes thrive. There are four varieties of malaria, and one species of mosquito that carries them all. The disease is caused by a germ, and the germ is carried by an insect which exists in warm & wet areas. As water flows to the lowest place, the lower altitudes are where you contract malaria. In terms of the specific question asked, it seems that the risk falls of with increasing altitude and is considered very low above 1500m ( approx 4900 feet).
