End of Poverty”. His article tackles malaria in Africa‚ a serious disease that’s jeopardizing the lives of millions of African children. Sachs provides a practical and low cost solution to malaria. Similarly‚ I believe that if those distributers would volunteer to hang the nets in African homes themselves‚ malaria prevention would have higher rates. In his article “The $10 Solution”‚ Sachs argues for a cheap and practical solution for the problem of malaria in Africa. The author starts by highlighting

COMMUNICABLE DISEASES Communicable diseases are illnesses that can be transmitted from one person to another. Some of the examples include; Gonorrhea Tuberculosis Malaria Meningitis Transmission is the passing of communicable diseases from an infected host individual or a con- specific (belonging to the same species) individual or group‚ regardless of whether the other individual was previously infected.

D MGT/216 DT - To Spray or Ban? An Historical Ethical Dilemma August 14‚ 2010 Malaria Malaria is a blood disease caused by the bite of a mosquito. In South Africa‚ it caused over 2.7 million deaths a year (Lawrence Berkley National Laboratory‚ 2010). There is no known vaccine that can cure malaria. The only solution is to eradicate the cause- the mosquito. A scientist named Dr. Paul Herman Muller made an insecticide-DDT (dichlorodiphenyltrichloroethane) in 1939. Although

Antibiotics are medications used to kill or prevent the spread of disease causing bacteria in the body. There are two types of antibiotics which manage infectious diseases differently: 1. Bactericidal Antibiotics: this is when the antibiotic completely kills off the Bacteria. It does this by damaging or interfering with the bacteria’s cell contents or wall. An example of this type of antibiotic is Penicillin which is in fact the first type of antibiotic to be discovered. 2. Bacteriostatic Antibiotics:

Observations: When Malaria is present and infects red blood cells‚ parasites can infect cells carrying defective hemoglobin which may result in death. Allele frequency changes over time depending on the pressures or circumstances facing a particular population. African populations are especially impacted by both malaria and sickle cell anemia. Depending on the impacted population‚ allele frequency often shifts and well suited organisms are likely to survive and allele frequencies can increase
