Mosquitoes long have been taking a bite out of warm-weather fun. Now, that bite carries with it the danger of Zika virus, West Nile virus and other mosquito-borne illnesses.
Zika is transmitted primarily by Aedes mosquitoes, aggressive biters that can strike during the day and at night. It has appeared in parts of Africa, Southeast Asia and the Pacific Islands, as well as Central and South America, Mexico and the continental United States. In 2016, mosquito-borne transmission of Zika virus was reported in Miami-Dade County, FL, and Cameron County, TX, according to the Centers for Disease Control and Prevention.
Anyone who lives in or travels to an area with Zika and has not already been infected can get the disease.
Others will have mild symptoms, including fever, rash, conjunctivitis (Pink Eye) and muscle pain or headache lasting two to seven days, that can be treated with rest, fluids and acetaminophen, according to the World Health Organization.
Scientific consensus is that Zika causes microcephaly and Guillain-Barré syndrome. In infants, a small head due to abnormal brain development is the defining characteristic of microcephaly. Guillain-Barré, characterized by the body's immune system attacking the peripheral nervous system, typically affects adults and can result in paralysis.
In an infographic, the CDC highlights Things Everyone Needs to Know About Zika:
Employers need to identify those at greatest risk for Zika, including:
Employers should provide education about the risk of Zika and other mosquito-borne illness, supply mosquito repellant and furnish clothing treated with permethrin, an insecticide. In medical centers and labs, be sure employees strictly adhere to procedures regulating the use of needles and wear personal protective equipment – gloves, gowns, masks and eye protection.
OSHA and NIOSH offer guidelines for protecting workers from occupational exposure to Zika virus. Government agencies and municipalities also are urged to enact or renew mosquito abatement plans. EPA-approved treatment of ponds and standing water is one of the most common ways agencies have attacked mosquito larva.
Localized adult mosquito biological control also might include the introduction of birds, bats, dragonflies and frogs into the eco-system.
