How can vector borne diseases be controlled?

  • There are different methods of controlling vector borne diseases. But these methods are not effective when used alone. Thus, Integrated Vector Management is the most effective way of controlling vector borne diseases.


What is Integrated Vector Management or IVM?

  • Integrated Vector Management (IVM) is defined by WHO as a rational decision-making process to optimize the use of resources for vector control. It is based on evidence and integrated management, promoting the use of a range of interventions – alone or in combination – selected on the basis of local knowledge about the vectors, diseases and disease determinants. 


What are different methods that can be used in IVM?

  • IVM involves integration of various non-chemical and chemical methods in a rational way. This includes physical, mechanical, biological, genetic and chemical interventions.
