1. Malaria :-
• Half of the world’s population
at risk of malaria
• Mosquito-borne infectious
disease affecting humans

11. 2. Dengue fever :-
• Mosquito-borne tropical
disease caused by the dengue
virus
• Currently no vaccines
• Symptoms:-
high fever, headache,
vomiting, muscle and joint
pains, and a characteristic skin
rash
Dengue virus

12. Prevention :-
• Stagnant water bodies.
• Mosquito traps and nets
• Repellents
• Avoid scent
• Door & window screen
• Clothing
• Clean surrounding
Mosquito Net
Spreading Mosquito killing solvents
Cleaning the surroundings of the locality 12

13. 3.Chikungunya :-
• It is also caused by mosquito
named ( Aedes
albopictus and Aedes
aegypti.)
• Similar to dengue fever
• Symptoms :-

14. Prevention :-
• Using insect repellent
containing DEET
• Wearing clothing that covers
the whole body
• Staying indoors as much as
possible
Applying insect repellents
Thermal Fogging

15. 4. Schistosomiasis
• Known as snail fever and
bilharzia
• Cause- parasitic flatworms.
• parasites are released from
infected freshwater snails
• Symptoms:-
abdominal pain, diarrhea, blood
in the urine, etc.
• Damage to urinary tract or
the intestines

spread by mosquitoes

fever.
• Three phase:-

toxic phase.
• Symptoms :-
headache, muscle ache, joint
ache, chills, fever, abdominal
pain, vomiting,
Flavivirus of yellow fever virus

18. Prevention
• Vaccination is the only way
to prevent yellow fever
• using insect repellant
• wearing clothing to reduce
mosquito bites

19. 6.Cholera
• It a type of diarrheal illness
• Causes death of about
hundred-thousand death
• Cholera affect mainly the
small intestine
• Transmitted through the
legs of house fly

20. Conclusion
• Vector borne diseases –the greatest mortality
for humans
• Environmental changes increases spread of
diseases
• Vector control programs need to adapt to
match the changes epidemiological pattern of
the new emergence
