Approximately 100,000 people die each year from complications of sickle cell disease, with most deaths occurring in sub-Saharan Africa. Early detection, proper management, and access to healthcare can help improve outcomes for individuals with sickle cell disease.

Is it good to have sickle cell?
Yes, and no. No, because when you do have sickle cell anemia, your irregular blood shape interferes with the blood's ability to carry oxygen and pass through narrow openings such as the capillary. People who have sickle cell die relatively early because of the organ damage and lack of oxygen caused by the blood's irregularity. Yes, because it has been found that people with sickle cell anemia are protected against malaria.
Will your infant die from sickle cell?
Although Sickle Cell Anemia sufferer's often have a shorter life expectancy, infants do not usually die from it. However it is important to get blood tranfusions.
How does balancing selection affect the sickle cell allele in central Africa?
The sickle cell allele can be maintained in the central African population, above the frequency of gene mutation (balancing selection), because the heterozygous sickle cell individuals have an advantage in lifespan, in this malaria stricken region, over the homozygous alternatives. Homozygous sickle-sickle individuals die early from the sickle cell disease. Homozygous nonsickle-nonsickle die early from malaria. The heterozygous sickle-nonsickle have a higher survival against malaria and therefore the sickle cell allele is balanced selected.
Can you die from sickle cell anemia?
Yes, and no. No, because when you do have sickle cell anemia, your irregular blood shape interferes with the blood's ability to carry oxygen and pass through narrow openings such as the capillary. People who have sickle cell die relatively early because of the organ damage and lack of oxygen caused by the blood's irregularity. Yes, because it has been found that people with sickle cell anemia are protected against malaria.
What is the common name for sickle cell anemia?
It is a genetic disorder. However... It is also a protection against malaria. For example, if a person were born in an area where malaria is present, he or she would likely die from the disease, unless he or she inherited 1 sickle cell gene. Malaria viruses reproduce in the red blood cells. The parent virus invades a cell, and uses the cell as a host to grow more viruses. With 1 sickle cell gene, malaria viruses that invade a red cell are quickly destroyed, since the red cell collapses, preventing the virus from reproducing. But with 2 sickle cell genes, red cells collapse too easily; just a bruise can cause someone to become anemic when too many red cells collapse. In the real world, people with no sickle cell genes died from malaria. People with 1 sickle cell gene survived. People with 2 sickle cell genes died from sickle cell anemia. It was natures way of assuring that at least half of the population survive, but it is certainly a difficult thing to live with today, now that we can more easily treat malaria.
What are the chances of a person having a sickle cell disease passing the disease to their offspring?
If one represents a sickle cell gene thus "C" and a normal gene thus "O" then both parents are: Mum CO Dad CO The possibilities for their children are therefore CC OO CO CO in those proportion so 1in 4 will have sickle cell anaemia, 2 in 4 will be carriers (like their parents) and 1/4 will be normal.
Is sickle cell deadly?
Yes. It is a genetic disease passed by both parents with the sickle cell trait and it is very painful for the person who has it. They eventually, die of it.
Why heterozygous for sickled cell anemia are resistant to malaria?
Because individuals who inherit the gene from only one parent produce red blood cells which are distorted. This distortion makes the cells unpalatable to malaria parasites, without seriously harming the individual. This tends to protect against malaria and that protection causes selection for this allele. Individuals who get the sickle cell gene from both parents suffer serious distortion of the red blood cells. This protects against malaria, but also reduces the oxygen-carrying capacity of the red cells to a dangerous degree. This causes a disease called sickle-cell anaemia, which causes selection against the gene. In malarial regions a balance is established. When a population with sickle cell alleles moves to an area with effectively no malaria present, the sickle cell alleles are steadily selected against. This shifts the balance steadily towards low levels.
How does a person with sickle-cell allele differ from a person with two sickle-cell alleles?
If a person has a single sickle cell allele they will have some sickles red blood cells, and some normal red blood cells. This is the origami purpose that this evolved for. If a person had a single sickle cell allele, they will be mostly resistant to malaria. This is why sickle cell anemia is most prevalent in areas of the world where malaria is common. However, if a person has two sickle cell anemia alleles, they will have ONLY sickled red blood cells. The "sickling" of the red blood cells is caused by a mutation in the protien that the gene codes for. That protein is hemoglobin, which carries oxygen through the blood. If a person has sickle cell anemia, parts of their body wil not get enough oxygen. They can pass out, loose sensation in the limb, or even die from it. In short, a person with two alleles is sick, and a person with one allele is not.
How is it possible for only some races to have certain diseases or deformities like Sickle-Cell Anemia for African-Americans and Head Lice for Caucasians?
Some diseases are the result of adaptations to an environment. As it turns out, Sickle Cell Anemia is an adaptation to Malaria. If a person has a single copy of the Sicke Cell gene, he or she is protected against Malaria. If he or she has NO copies of the gene, he or she will die if exposed to Malaria. If he or she has two copies of the gene he or she will die from Sickle Cell Anemia. Malaria was fatal to pretty much everyone. The genetic mutation allowed about half of the population of the region to live. Today, we no longer have the threat from Malaria so now Sickle Cell Anemia becomes the problem.
