VECTOR CONTROL

            VECTOR CONTROL 

   Vector is simply a disease carrier. A typical example is
anopheles mosquito which transmit malaria. It may be an insect
especially anthropod or animal. They carry and transmit
infections pathogens directly or indirectly from an infected
animal to a human or from an infected human to another human.

Vector                 Associated disease
                             
Flies                         Diarrhoel disease

Mosquitoes             Malaria and Yellow fever

Rats                          Leprospirosis and salmonellosis

Flees                        Typhus and Plague

Mite                         Scabies

Lice                           Epidermic typhus and Relapsing              
Fever

Tick                           Relapsing fever

      The key to vector control is to adopt the following principles :

1. know as much about the vector as possible

2. Prevent the vector from breeding

3. Control/Eliminate the vector at the earliest point in his life
cycle

4. Control/Eliminate the transmission vector to prevent disease

5. Personal protection .

IMPORTANCE OF VECTOR CONTROL

Some of these diseases have know effective cure,
such diseases are zika virus and Dengue fever e.t.c. However vector control remains the only way to protect human populations.
Even for vector-borne diseases with effective treatments the high cost of treatment remains a huge barrier to large amounts of developing world populations. Despite being treatable. malariahas by far the greatest impact on human health  such as africa.

The impacts of disease and virus are devastating, the need to control the vectors in which they carried is prioritized. Vector control in many developing countries can have tremendous impacts as it increases mortality rates, especially among infants. Because of the high movement of the population, disease spread is also a greater issue in these areas.
The world health organization recommends the vector management.

        Common preventive measures are:
               
                ENVIRONMENTAL CONTROL

- open pit burning
- Dropping in uncovered bin
- Burrying  without treatment
- Use of cart pushers to transport waste
- Use of unaccredited waste collectors
- Burning in furnace
- Use of cellophane bags for collection of waste.


                     CHEMICAL CONTROL

    Insecticides can be applied to house walls or bed nets, and use of personal repellents can reduce incidence of insect bites and thus infection.For example, larvicides can be used in mosquito breeding zones.

                     REDUCING CONTACT


     Also limiting exposure to insects or animals that are also known as disease vectors can reduce infection risks significantly. For example, bed nets, window screens on various homes, or protective clean clothing can help reduce the likelihood contact with vectors. To be effective this requires education and promotion of methods among the population to raise the awareness of vector threats. READ MORE
