Malaria and Sickle Cell Anemia
Transcript
Problem
- Malaria is a highly infectious and deadly disease and is prevalent in areas where medical treatment is not always available.
Background
- Malaria is a disease caused by a parasite, spread by mosquitoes in tropical environments. Symptoms include chills, fatigue, fever, vomiting, diarrhea, and fast heart rate. It can be treated with antiparasitics and antibiotics and can be cured with extensive treatment. However, it is most prevalent in places where medical attention is not readily available. Over 1 million people die in Africa alone each year from Malaria, mostly children under 5.
- People of African descent are more likely to be affected by Sickle Cell Anemia. Symptoms include anemia, joint pain, chest pain, dizziness, fatigue, and low O2 levels. Some treatments can help but can not be cured. People with this disease can live a decent life.
Sickle Cell Anemia
Sickle Cell Anemia provides protection against Malaria
Malaria
Background
- Sickle Cell Anemia is a genetic disease that causes malformation of the red blood cells making it difficult for them to carry oxygen through the blood stream. It is caused by a mutation of the gene that created hemoglobin.
Solution
- Reducing the amount of mosquitoes and medicating the population would be helpful, natural selection is providing its own solution to the Malaria epidemic. Since Sickle Cell Anemia provides resistance to Malaria those with Sickle Cell are more likely to survive in a high Malaria environment. This leads to Sickle Cell Anemia becoming more prevalent in high Malaria environments due to the difference in surviorship. In the U.S. the threat of Malaria has greatly decreased which has lead to the African American population in the U.S. having less of a chance of having sickle cell since the pressure of Malaria is no longer on them.
