1. MALARIA BY,, HARVINDER JASSEL, PARMEET KALER, RINA BHINDER AND SATVIR JAGDEV. [VILLIERS HIGH SCHOOL]

2. INTRODUCTION In this presentation we are going to answer the questions: In this presentation we are going to answer the questions: 1 : Without human intervention, is the transmission index always the same for any disease? 2 : How could the transmission index be altered for malaria?

3. RESEARCH For the last couple of weeks we have been finding information using different types of media. Such as the book foundations in parasitology, CD Roms Encarta and Britannica, and the websites www.who.int. www.bio.cam.ac.uk www.malaria.org.

Finally, we have come up with a few answers and suggestions.

4. QUESTION NUMBER 1 Without human intervention, the transmission index for any disease isnt always the same. The transmission index depends on how easily a disease can be passed on. For example if an infection is transmitted through air particles, such as the common cold and influenza virus, the index will be higher than if it is transmitted via sexual contact.

5. Examples of diseases transmitted this way include HIV, herpes and syphilis. The transmission index could also be affected by the weather. For example mosquitoes live in hot conditions and this may also be one of the reasons why malaria is no longer present in this country.

6. QUESTION NUMBER 2 The transmission index for malaria can be altered by preventing the mosquitoes infecting you. You can do this by: The transmission index for malaria can be altered by preventing the mosquitoes infecting you. You can do this by: Taking your anti-malarial drug exactly on schedule without missing doses. Taking your anti-malarial drug exactly on schedule without missing doses. Prevent mosquito and other insect bites. Use DEET insect repellent on exposed skin and flying insect spray in the room where you sleep. Prevent mosquito and other insect bites. Use DEET insect repellent on exposed skin and flying insect spray in the room where you sleep.

7. SOME MORE INFO Wear long pants and long-sleeved shirts, especially from dusk to dawn. This is the time when mosquitoes that spread malaria bite. Wear long pants and long-sleeved shirts, especially from dusk to dawn. This is the time when mosquitoes that spread malaria bite. Sleep under a mosquito bed net that has been dipped in permethrin insecticide if you are not living in screened or air-conditioned housing Sleep under a mosquito bed net that has been dipped in permethrin insecticide if you are not living in screened or air-conditioned housing

8. Mosquito repellent Emits variable frequency waves repelling several species of mosquito. No maintenance, no refills, no insecticides. 1 unit covers a room 25 sq m. Not harmful to pets. Liquid mosquito killer. Safely destroys mosquitoes and other flying insects. Dual voltage for world wide use. Uses liquid or any approved tablet. Power indicator light.

9. MALARIA CHART Despite what we know about the transmission index the occurrence of malaria has still increased over the last 30 years. This may be as a result of lack of education, general poor health, not having suitable drugs and mosquitoes no longer being effected by the drugs.

10. SUMMARY In order to reduce the transmission index of malaria we suggest you do the following: Take anti-malarial drugs Prevent yourself from being bitten

11. CONCLUSION In conclusion we believe that the transmission index isnt always the same and the transmission index for malaria can be altered.
