Filariasis,rthropod vectors. These arthropod vectors are obligate, intermediate hosts for the parasite, necessary for development from the microfilaria to the . or . (commonly abbreviated ”.”). This is the stage infectious to vertebrates. None of the nematode larvae propagates in the vector.

Surveillance for Arthropodborne Diseases,finitely, whereas surveys are of limited duration. Surveillance may involve detecting cases within human and animal populations, monitoring infectious agents in natural vectors or reservoir animals, seroconversions in sentinel animals, estimating vectors or reservoir host population abimdance, and assessing weather patterns.
