The area surrounding the city of Genericville is a perfect home and breeding ground for mosquitoes that possibly could be carrying the West Nile Virus (WNV). There is a high risk for citizens of Genericville to become a carrier of this deadly virus. With fatalities being reported action is need to reduce illnesses caused by mosquitoes. To reduce the population of mosquitoes spraying with Malathion, could be suggest as a hazardous insecticide.
In 2007, The Center of Disease Control and Prevention reported there were 4,269 WNV cases in the U.S. in 2006 (2007). That number includes the 177 fatalities that were reported as well. The testing results of infected birds and mosquito breeding areas suggest that in the city of Genericville approximant 50 people will be infected with the West Nile Virus and two people will lose their lives this year.
The application of Malathion could reduce problems cause by mosquitoes. Using Malathion is estimated to reduce the population of mosquitoes by 90%. Spraying will also provide the same results the risk of contracting the West Nile Virus. Using the reports from the Center of Disease Control and Prevention and the possibly reduction by using Malathion the number of people who could become affect would drop from 50 to five and lower the chance of fatalities to less than 20%.
Consensus is that some citizens are tolerant to high doses of Malathion although some are highly reactive to low doses. After aerial spray, a mist can be formed and all residents can be at risk of breathing the chemical. Even though Malathion breaks down rapidly children and elderly citizens are expected to react more than others to doses of Malathion. They become a high risk of acquiring the bad effects of the insecticide. Areas with high concentration of Malathion also have a high risk of receiving negative effects. Contact could be made through skin, inhaling, or ingestion. Prior to aerial spraying an intensive education class will provide safety precaution to help reduce risks.
Exposure to citizens of Malathion in large amounts is not likely. Citizens at risk of exposure are uneducated citizens and those who are unaware about the aerial spraying. Another risk would be the consumption of food that was contaminated with Malathion. Some prediction of the application of Malathion would kill not only mosquitoes but mosquito predators and the ecosystem. According to the Agency for Toxic Substance and Disease Registry the rapid degradation of Malathion applications has no long-term environmental risk because of the transformation into harmless materials (Agency for Toxic Substances and Disease Registry, 2005, Section 1).
