7. Mosquito & Malaria: Introducing the Disease in brief
Malaria is a life threatening parasitic disease caused by parasites known as
Plasmodium viviax (P.vivax), Plasmodium falciparum (P.falciparum), Plasmodium
malariae (P.malariae) and Plasmodium ovale (P.ovale).
It is transmitted by the infective bite of Anopheles mosquito.
Man develops disease after 10 to 14 days of being bitten by an infective mosquito.
There are two types of parasites of human malaria, Plasmodium vivax, P.
falciparum,which are commonly reported from India.
Inside the human host, the parasite undergoes a series of changes as part of its complex
life cycle. (Plasmodium is a protozoan parasite).
The parasite completes life cycle in liver cells and red blood cells.
Infection with P.falciparum is the most deadly form of malaria.
Historical Prospective: Malaria from beginning
Malaria has been a major public health problem in India. Intermittent fever, with high
incidence during the rainy season, coinciding with agriculture, sowing and harvesting,
was first recognized by Romans and Greeks who associated it with swampy areas. They
postulated that intermittent fevers were due to the 'bad odour' coming from the
marshy areas and thus gave the name 'malaria' ('mal'=bad + 'air') to intermittent
fevers. In spite of the fact that today the causative organism is known, the name has
stuck to this disease.

8. Symptoms of Malaria : Identification of the Disease
Typically, malaria produces fever, headache, vomiting and other flu-like symptoms.
The parasite infects and destroys red blood cells resulting in easy fatigue-ability due to
anemia, fits/convulsions and loss of consciousness.
Parasites are carried by blood to the brain (cerebral malaria) and to other vital
organs.
Malaria in pregnancy poses a substantial risk to the mother, the fetus and the newborn
infant. Pregnant women are less capable of coping with and clearing malaria infections,
adversely affecting the unborn fetus.
Vector of Malaria : Protozoa Carrier
There are many vectors of malaria.
Anopheles culicifacies is the main vector of malaria.It is one types of mosquito.
It is a small to medium sized mosquito with Culex like sitting posture
1. Feeding habits
It is a zoophilic species
When high densities build up relatively large numbers feed on men
2. Resting habits
Rests during daytime in human dwellings and cattlesheds
3. Breeding places
Breeds in rainwater pools and puddles, borrowpits, river bed pools, irrigation channels,
seepages, rice fields, wells, pond margins, sluggish streams with sandy margins.
Extensive breeding is generally encountered following monsoon rains.
4. Biting time
Biting time of each vector species is determined by its generic
character, but can be readily influenced by environmental conditions.
2

9. Most of the vectors, including Anopheles culicifacies, start biting soon after dusk.
Therefore, biting starts much earlier in winter than in summer but the peak time varies
from species to species.
Malaria Control Strategy: Elimination of the Disease Malaria
1. Early case Detection and Prompt Treatment (EDPT)
 EDPT is the main strategy of malaria control - radical treatment is necessary for
all the cases of malaria to prevent transmission of malaria.
 Chloroquine is the main anti-malaria drug for uncomplicated malaria.
 Drug Distribution Centres (DDCs) and Fever Treatment Depots (FTDs) have been
established in the rural areas for providing easy access to anti-malarial drugs to
the community.
 Alternative drugs for chloroquine resistant malaria are recommended as per the
drug policy of malaria.
2. Vector Control
(i) Chemical Control
 Use of Indoor Residual Spray (IRS) with insecticides recommended under the
programnme
 Use of chemical larvicides like Abate in potable water
 Aerosol space spray during day time
 Malathion fogging during outbreaks
(ii) Biological Control
 Use of larvivorous fish in ornamental tanks, fountains etc.
 Use of biocides.
(iii) Personal Prophylatic Measures that individuals/communities can take up
 Use of mosquito repellent creams, liquids, coils, mats etc.
 Screening of the houses with wire mesh
3

10.  Use of bednets treated with insecticide
 Wearing clothes that cover maximum surface area of the body
Life Cycle of the Malaria Parasite
1. A female Anopheles mosquito carrying malaria-causing parasites feeds on a human and
injects the parasites in the form of sporozoites into the bloodstream. The sporozoites
travel to the liver and invade liver cells.
2. Over 5-16 days*, the sporozoites grow, divide, and produce tens of thousands of haploid
forms, called merozoites, per liver cell. Some malaria parasite species remain dormant
for extended periods in the liver, causing relapses weeks or months later.
3. The merozoites exit the liver cells and re-enter the bloodstream, beginning a cycle of
invasion of red blood cells, asexual replication, and release of newly formed merozoites
from the red blood cells repeatedly over 1-3 days*. This multiplication can result in
thousands of parasite-infected cells in the host bloodstream, leading to illness and
complications of malaria that can last for months if not treated.
4. Some of the merozoite-infected blood cells leave the cycle of asexual multiplication.
Instead of replicating, the merozoites in these cells develop into sexual forms of the
parasite, called male and female gametocytes, that circulate in the bloodstream.
5. When a mosquito bites an infected human, it ingests the gametocytes. In the mosquito
gut, the infected human blood cells burst, releasing the gametocytes, which develop
further into mature sex cells called gametes. Male and female gametes fuse to form
diploid zygotes, which develop into actively moving ookinetes that burrow into the
mosquito midgut wall and form oocysts.
6. Growth and division of each oocyst produces thousands of active haploid forms called
sporozoites. After 8-15 days, the oocyst bursts, releasing sporozoites into the body cavity
of the mosquito, from which they travel to and invade the mosquito salivary glands. The
cycle of human infection re-starts when the mosquito takes a blood meal, injecting the
sporozoites from its salivary glands into the human bloodstream.

13. Aims &Objective

14. Aims & Objective: The Goal
To prevent malaria in the malaria prone area of district Bankura and to make a brief
monitoring on malaria prevention strategy taken by the stakeholder. This project may
help the stakeholder of the malaria control programme for further planning.

16. Methods
&
Methodology

17. Method & Methodology: The technique utilized
To observe the way of work of stakeholder (Govt. Agencies/NGO etc.) for prevention of
malaria, I prepared a format. In that format, I note down the prevention techniques
implemented by the stakeholder. This filled up, format can analyse the preventive work
done by the stakeholder.
Question & Answer method is used here. Random selection of persons & household has
been done in malaria prone blocks of Bankura District.
I also collect the data of malaria cases found in the 8 malaria blocks of the district
bankura which may help me in my interpretation.
A score line sheet has been sets up for analyzing the data as follows:

35. Discussion

36. Discussion:
From my study it has been proved that the Blocks had done the preventive steps properly good
minimized the disease condition.
Malaria prevention can be done by taking the preventive steps before the rainy seasons came.
Ranibandh had the more worst stage regarding the malaria condition from other blocks.
Raipur block as taken the better preventive steps in this year 2014 so less malaria cases found
there.
So, Prevention is better than the cure.
