PREVENTING AND CONTROLLING
VECTOR BORNE DISEASES
• Simple, cost-effective interventions like
insecticide-treated bed nets and indoor
spraying have already saved millions of lives,”-
Dr Margaret Chan, WHO Director-General.
• “No one in the 21st century should die from
the bite of a mosquito, a sandfly, a blackfly or
• According to the World Health Organisation
(WHO), more than 2.5 billion people in the
world are now at risk of suffering from
• The Aedes aegypti mosquito is the primary
vector of dengue.
SIGNS AND SYMPTOMS OF
• Sudden-onset fever
• Headache (typically located behind
• Muscle and joint pains
PREVENTION AND CONTROL

management and modification.
• Disposing of solid waste properly.
• Covering, emptying and cleaning of domestic
water storage containers on a weekly basis.
• Using of personal household protection.
• Supports countries in the confirmation of
• Provides technical support and guidance to
• Supports countries to improve their reporting
• Provides training on clinical management,
diagnosis and vector control.
• Applying appropriate insecticides to water
storage outdoor containers
• Improving community participation.
• Applying insecticides as space spraying during
• Active monitoring and surveillance of vectors
• Formulates evidence-based strategies and
• Develops new tools, including insecticide
products and application technologies.
• Gathers official records of dengue and severe
dengue from over 100 member states.
• Publishes guidelines and handbooks for case
management, dengue prevention and control.
• Malaria is a life-threatening disease caused by
parasites that are transmitted to people
through the bites of infected anopheles
• In 2012, malaria caused an estimated 627 000
deaths (with an uncertainty range of 473 000
to 789 000), mostly among African children.
PREVENTION AND CONTROL
• Insecticide-treated mosquito nets
• Indoor spraying with residual
• setting, communicating and promoting the
adoption of evidence-based norms, standards,
policies, technical strategies, and guidelines;
• keeping independent score of global progress;
• developing approaches for capacity building,
systems strengthening, and surveillance;
• identifying threats to malaria control and
elimination as well as new areas for action.
• Leishmaniasis is caused by the
protozoan Leishmania parasites which are
transmitted by the bite of infected sandflies
• An estimated 1.3 million new cases and 20000
to 30 000 deaths occur annually.
• The cutaneous form: presents with skin ulcers
• Mucocutaneous form: presents with ulcers of
the skin, mouth and nose
• Viceral form: starts with skin ulcers and than
latter presents with fever, low red blood cells,
and a large spleen and liver.
PREVENTION AND CONTROL
• Early diagnosis and effective case
• Vector control
• Effective disease surveillance
• Control of reservoir hosts
• Social mobilization and strengthening
• Providing technical support to build
sustainable, effective surveillance system and
epidemic preparedness and response.
• Strengthening collaboration and coordination
• Monitoring the global leishmaniasis situation,
trends and measure progress in the disease
control, and financing
• Promoting research on effective leishmaniasis
• Supporting national leishmaniasis control
• Raising awareness and advocacy on the global
burden of leishmaniasis.
• Promoting equitable access to health services
for disease prevention and case management.
• Developing evidence-based policy guidelines,
strategies and standards.
• Schistosomiasis is an acute and chronic
disease caused by parasitic worms.
• The number of people reported to have been
treated for schistosomiasis in 2012 was 42.1
million and 249 million taken preventive
• People become infected when larval forms of
the parasite released by freshwater snails
penetrate the skin during contact with
Prevention and control
• Large-scale treatment of at-risk population
groups, access to safe water, improved
sanitation, hygiene education and snail
• The WHO strategy for schistosomiasis control
focuses on reducing disease through periodic,
targeted treatment with praziquantel
• Preventive chemotherapy in consultation with
• WHO develops technical guidelines and tools
for use by national control programmes.
• Increased access to praziquantel and
resources for implementation
• Chagas disease or American trypanosomiasis,
is a potentially life-threatening illness caused
by the protozoan parasite, Trypanosoma cruzi.
• About 7 million to 8 million people are
estimated to be infected worldwide, mostly in
Latin America where Chagas disease is
PREVENTION AND CONTROL
• Spraying of houses and surrounding areas
with residual insecticides.
• House improvements to prevent vector
• Personal preventive measures such as
• To kill the parasite, Chagas disease can be
treated with benznidazole and also nifurtimox
• There is no vaccine for Chagas disease.
• Vector control is the most effective method of
• Good hygiene practices in food preparation,
transportation, storage and consumption.
• Screening of blood donors.
• Testing of organ, tissue or cell of donors and
• Screening of newborns and other children of
infected mothers to provide early diagnosis
• Strengthening world epidemiological
surveillance and information systems.
• Preventing transmission by blood transfusion
and organ transplantation.
• Promoting the identification of diagnostic
tests for screening and diagnosis of infections.
• Expanding secondary prevention of congenital
transmission and case management of
congenital and non-congenital infections.
• Nearly 1.4 billion people in 73 countries
worldwide are threatened by lymphatic
filariasis or elephantiasis.
• Over 120 million people are currently
infected, with about 40 million disfigured and
incapacitated by the disease.
WHO’s strategy is based on 2 key components:
• stopping transmission through large-scale
annual treatment of all eligible people in an
area or region where infection is present.
• alleviating the suffering caused by lymphatic
filariasis through increased morbidity
management and disability prevention
• Large-scale treatment (mass drug
Albendazole (400 mg) together with
ivermectin (150-200 mcg/kg) or with
diethylcarbamazine citrate (DEC) (6 mg/kg).
• Morbidity management and disability
• Vector control
