Purpose…. • To prevent Dengue Fever through community participation
Expect To Have These Questions Answered…… • What is Dengue Fever? • How common is it? • What causes it ? • How is it transmitted? • What are the symptoms? • Can we treat it? • What can be done to prevent it?
What is Dengue Fever? • Dengue Fever is a virus. There are 4 strains of dengue virus. People can get dengue fever more than once because they can be infected by a different strain each time. • Second infection can lead to DHF • WHO. (2009). Dengue.

Situation in Thailand • Until 2003 Thailand had the highest number of cases in Southeast Asia • Currently in 2nd place after Indonesia and has 23% of all cases in region-about 50,000 • Less than 1% mortality rate • WHO.

Basic Facts • Spread by the bite of a mosquito • Symptoms begin 4-7 days after bite • Mosquito rests indoors or outdoors • Lays eggs in water containers outside near houses, schools, buildings • Barrels, buckets, vases, plant saucers, anywhere that rain water collects
Prevent Mosquito Bites • Wear clothing to cover the skin • Mosquito repellent, local brand Jaico works well • Use mosquito coils to keep mosquitoes away • Use nets to protect babies • Use nets around a patient infected with dengue WHO.

What Else Can We Do As a Community? • Inform neighbors • Be vigilant of common areas • When going on vacation, arrange for someone to remove any standing water that may accumulate.
