Vector Control

NACCHO supports local health departments in protecting their communities from the bacterial and viral diseases transmitted by mosquitoes, ticks, rodents, and other emerging vectors. Through development of new tools and resources, policy statements, Stories from the Field, and more, NACCHO helps local health departments increase their capacity to address existing and emerging issues related to vector control and integrated pest management.

Mosquito-borne diseases are diseases of humans and/or animals caused by bacteria, viruses, or parasites transmitted by mosquitoes. The list of mosquito-borne diseases is long (e.g., malaria, dengue, West Nile virus, Zika virus, chikungunya, yellow fever, filariasis, La Crosse encephalitis, Eastern equine encephalitis, Saint Louis encephalitis, etc.).

According to the World Health Organization, mosquitoes cause millions of deaths every year (WHO, Mosquito-borne diseases). Vector control has been an effective tool to control mosquito populations historically and continues today with conventional and updated tools. Integrated mosquito management and integrated vector management programs and guides have been developed to address the complexities of effective vector control strategies. The IVM approach is to "improve the efficacy, cost-effectiveness, ecological soundness and sustainability of disease-vector control" (WHO, IVM).

Mosquito Surveillance and Control Assessment in Zika Virus Priority Jurisdictions

NACCHO, in collaboration with the Centers for Disease Control and Prevention (CDC), has released a summary of findings evaluating vector control capacity across ten Zika virus (ZIKV) priority jurisdictions. Mosquito control activities were assessed across jurisdictions in Alabama, Arizona, California, Florida, Georgia, Hawaii, Louisiana, Mississippi, Texas, and Los Angeles County, each identified as vulnerable for potential impact resulting from ZIKV.

NACCHO's assessment of mosquito control and surveillance activities in Zika virus priority jurisdictions provided important findings. These findings supported the formation of a Vector Control and Surveillance working group, run by NACCHO, funded by CDC, and comprised of representatives from local vector control organizations as well as subject matter experts. This working group will participate in the following activities:

  • Discuss and share current vector control and surveillance plans;
  • Identify challenges, resources used, and resources needed related to Zika response at the local level;
  • Share public information communications tools and resources related to Zika with NACCHO and other state and local health officials; and
  • Inform, review, and comment on a NACCHO-developed technical assistance program focused on improving vector control and surveillance capabilities at the local level.
