VECTOR BORNE DISEASES Flashcards
What is a vector?
an insect or any living carrier that transports an
infectious agent from an infected individual or its wastes to an susceptible individual.
Examples of vector
- Mosquito
- Ticks
- Fleas
- Snails
Vectors can carry infective pathogens such as
viruses, bacteria, protozoa
(Mosquito) Aides
Dengue, Chikungunya
(Mosquito) Anopheles
Malaria
Tick
Lyme Disease, Encephalitis
Fleas
Plague
Snails
Schistosomiasis
What is vector borne disease
human illnesses caused by parasites, viruses
and bacteria that are transmitted by vectors.
are spread to people through the bite of an
infected Aedes species
DENGUE
Symptoms of Dengue
severe headaches, muscle and joint
pains, vomiting, swollen glands and rash
caused by Plasmodium parasites. The parasites
are spread to people through the bites of
infected female Anopheles mosquitoes
mALARIA

genus Schistosoma
Schistosomiasis

VECTOR-BORNE DISEASE PREVENTION AND
CONTROL
Using nets at door
using mosquito nets when sleeping outdoor
Paying attention to the cleanliness of animals
Maintaining personal hygiene
Avoiding travelling to the countries/places
stricken by vector-borne diseases
Making sure to the the necessary preventive
drugs and vaccines when travelling
Environmental factors related to vector borne disease
Deforestation
Urbanization
Loss of Biodiversity
Climate Change
A crucial element in reducing the burden of vector-borne diseases is
Behavioral Change
