MALARI
common life threatening disease in many tropical countrie
- in Africa alone, more than a million children die each yea
- control measures introduced have reduced malaria transmission signi cance
- transmitted to humans by a bite of an infected female anopheles mosquit
- malaria only occurs where these mosquitos are found as only they can spread i
- can occur in non-malaria areas if a veto mosquito is somehow transported via a truck for
exampl
- humans and mosquitos are the hosts of the parasit
Parasitic protozoa: are one-celled, eukaryotic organisms that belong to kingdom
Protozoa. They cause diseases in humans and animal
eg. amoebic dysentery
malari
Features of the female anopheles mosquito
- smal
- prefer clean water for development of larval stage
- adult found close to larval sit
- female requires protein from blood meals for eggs to matures therefore only they can
spread malari
- found between sunset and daw
- prefer to feed near ground leve
Prevention methods:
Taken both against mosquito vectors and against malaria parasit
- vector control programmes: taken by government health authorities
- personal protection to avoid mosquito bite
- the use of chemoprophylaxis
The control of vector mosquitos and avoidance of bites is very important due to the
development of drug resistant parasites, drug side effects and contraindications.
The 4 species of the malaria parasite
- plasmodium falciparum : most common and can result in deat
- plasmodium malaria
