Match the control method for the correct drinking water hazard.Group of answer choicesOral vaccine is available but should be used with improvements in water and sanitation systems.Improved living conditions and the introduction of antibiotics have resulted in a significant reduction of the disease in industrialized countries. Access to safe water and adequate sanitation and hygiene, particularly among food handlers. Vaccinations are also available.Substitute sources with high levels (groundwater), with sources that have low levels (rainwater and treated surface water). Blend sources that have high and low levels. Technologies are also available to reduce the amount in water.Have water tested if you live near an agricultural field. Keep children away from areas where fertilizers are applied.

Match the controls with the correct disease.Group of answer choicesUse of insecticide-treated nets, indoor residual spraying, outdoor spraying and other methods such as adding chemicals to water bodies and use of insect repellents. Broad use of vaccine among children living in regions with moderate to high transmission.Vaccination is the single most important measure for prevention.  The prevention of outbreaks can only be achieved if the majority of the population is immunized. The vaccine is safe and affordable, and a single dose provides life-long immunity against the disease. Use insect repellent, wear long-sleeved shirts and pants, treat clothing and gear, or use screens and nets.There is no vaccine to prevent infection. The best way to prevent this is to protect yourself from mosquito bites. Use insect repellent, wear long-sleeved shirts and pants, treat clothing and gear, and take steps to control mosquitoes indoors and outdoors.Prevention and control depends on effective vector control measures. Community involvement can greatly improve vector control efforts substantially. A new vaccine is approved for use in children aged 9 to 16 years with laboratory-confirmed previous infection and living in areas where the disease is endemic.There is no commercial vaccine available to protect against infection. Prevention and control rely heavily on reducing the number of natural and artificial water-filled container habitats that support breeding of the mosquitoes. For protection during outbreaks, clothing which minimizes skin exposure to the day-biting vectors is advised. Repellents can be applied to exposed skin or to clothing in strict agreement accordance with product label instructions. Repellents should contain DEET, IR3535 or icaridin.Protection against mosquito bites during the day and early evening is a key measure to prevent infection. Special attention should be given to the prevention of mosquito bites among pregnant women, women of reproductive age, and young children. Personal protection measures include wearing clothing (preferably light-colored) that covers as much of the body as possible; using physical barriers such as window screens and closed doors and windows; and applying insect repellent to skin or clothing that contains DEET, IR3535 or icaridin. Eliminate mosquito breeding sites, including covering water storage containers, removing standing water in flower pots, and cleaning up garbage trash and used tires. No vaccine is yet available for the prevention or treatment of infection.
