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.
