Preventing Disease Spread by Mosquito and Tick Bites- Protect Yourself!

Ticks are bugs that feed on the blood of people and animals. When they bite you, they can make you sick. Two kinds of ticks found in Massachusetts can carry diseases — deer ticks and dog ticks.

Mosquitoes can spread diseases that make you sick. In Massachusetts, mosquitoes can give you eastern equine encephalitis (EEE) virus and West Nile virus (WNV).

DPH Zika Virus

​Zika virus is a mosquito-borne flavivirus (in the same family as yellow fever, dengue and West Nile viruses) previously found largely in Africa and Southeast Asia. In 2007, it was found for the first time on the Pacific island of Yap and subsequently in French Polynesia. In May 2015, the World Health Organization reported the first local transmission of Zika virus in the Western Hemisphere, with locally acquired cases identified in Brazil. As of January 15, 2016, local transmission had been identified in at least 14 countries or territories in the Americas, including Puerto Rico. Further spread to other countries in the region is likely.

An estimated 80% of persons infected with Zika virus are asymptomatic. In symptomatic infection, the incubation period is 3-12 days. Symptomatic disease is generally mild and characterized by at least two of the following:

  • acute onset of fever,
  • maculopapular rash,
  • arthralgia, and/or
  • nonpurulent conjunctivitis
  • Symptoms usually last from several days to 1 week.
  • Severe disease requiring hospitalization is uncommon, and fatalities are rare.
  • The most significant concern associated with Zika virus infection is for pregnant women.
