Malaria: so close but no cigar


| 1 Comment


        In current clinical practice, there is no vaccine given to patient with malaria. Malaria is a mosquito-borne disease that affects humans and other animals. it is caused by a type of microorganism that reacts in a mosquito's body. 

       Scientists and doctors typically exam the bloodline of the individual who is infected. by using tools as a blood film, the scientists can see the malaria. 

       Scientists are currently trying to study this infection. in a recent New York Times article, the author reports a story about a group of scientists who received unsatisfactory results for the leading candidate for the malaria vaccine. after they did in a clinical trial with families and babies, they received less numbers than they expected. '...In a trial in children up to 17 months old, the same vaccine gave 55 percent protection against detectable malaria and 47 percent against severe malaria"(McNeil Jr, 2012). Because of the disappointing results of the clinical trial, people and families will have to wait until definitive results are manipulated in the lab.

        what are the symptoms associated with Malaria? the symptoms usually occur after a week and are similar to the flu. 

        this disease is more diffused throughout the Western part of the world and places like southeast Asia and West Africa. there are many humanitarian projects developed for the fight of Malaria. 

       at this website, there is an organization devoted to fight Malaria and provide funding for research. 

      other scientists are still trying to develop an effective vaccine for it to save millions of lives. maybe, in the next decade or two mankind will see that happen. until then, this research is very modern and concrete.A question that concerns me is that if scientists know of the various species of mosquitoes that catch the virus. then, why not make a genetic mutation by engineering the evolutionary process and make these mosquitoes resistant to it so it will die off? this logic may seem un-flowing or a interesting idea. the contents and details to the solution of such question is unknown to this writer.

There are many of preventative measures scientist have given to the public who are affected by malaria, yet the disease still infects up to 200 million and kills 800,000. Although there is no cure for those have already contracted the disease, there are way to help from getting it. For those traveling to malaria infected regions, it's important that they know the risks and take a malaria vaccine. Also, simply not getting bitten by a mosquito by getting a mosquito net or fly repellant cream. A recent study has suggested that they have found a cure for malaria, but it is still in it's early stages and has yet to have human trials. I am quite surprised that we just haven't figured out a way to completely irradicate the specific kinds of mosquitoes that borne malaria, and if so why have we now.
