Vector-Borne Diseases

Hazard Overview

Hazard Overview

What is a vector?

Vectors are living organisms that can transmit infectious diseases between humans or from animals to humans. Many of these are bloodsucking insects that ingest disease-producing microorganisms after biting and sucking blood from an infected host (human or animal) and later inject it into a new host during their next blood meal.

The best-known of the disease vectors are mosquitoes. Other familiar disease vectors include ticks, flies, sandflies, fleas, triatomine bugs and some freshwater aquatic snails.

What are vector-borne diseases?

Vector-borne diseases are human illnesses caused by parasites, viruses and bacteria that are transmitted by mosquitoes, ticks and other disease vectors.

Some of the more commonly known vectors and associated vector-borne diseases are:

  • Mosquitos: malaria, West Nile fever, Yellow fever, Zika virus;

  • Ticks: Lyme disease, Rickettsial diseases (Rocky Mountain spotted fever and Q fever), tularemia

  • Fleas: plague, rickettsiosis

Who is at risk of exposure to vector-borne diseases?

Employees working in outdoor settings such as, but not limited to, agricultural operations, arboriculture and logging operations, and construction work are most at risk of becoming infected with a vector-borne disease.

What can I do to protect myself and others?

Employees who work outside can protect themselves against mosquito and tick bites, in particular, by following a few simple precautions. Use EPA-registered insect repellents containing one of the following ingredients: DEET; picaridin (known as KBR 3023 and icaridin outside the US); IR3535; oil of lemon eucalyptus (OLE); para-menthane-diol (PMD); and 2-undecanone.

Wear long-sleeved shirts and long pants when working outside. Treat items, such as boots, pants, socks, and tents, with insect repellant or buy insect repellant-treated clothing and gear.

What resources are available to assist employers?

Training and Outreach Services

The personal protective equipment and hazard communication presentations are available to assist employers in training their staff. Each of these presentations should be modified to address site-specific conditions and hazards. 

Further, the education, training and technical assistance bureau provides free online safety and health training and outreach services (i.e., speaker's bureau requests, safety booths) upon request. Further, a pre-recorded webinar on hazard communication can be used for employee training.

Lastly, the NCDOL Library offers free safety and health videos (including streaming video services) and related research assistance on consensus standards (i.e., ANSI, NFPA, NEC).

Safety and Health Programs

An example hazard communication program and personal protective equipment hazard assessment are available for employers to download and adapt to their specific conditions.
