The public and healthcare providers should be aware of the risk of eastern equine encephalitis (EEE), even in areas that have not previously had much activity. People should prevent infection by use of personal protective measures against mosquito bites, and doctors should test patients with aseptic meningitis or encephalitis for EEE in areas at risk for EEE transmission.
During August-September 2005, the New Hampshire Department of Health and Human Services reported seven cases of eastern equine encephalitis (EEE), the first laboratory-confirmed cases of EEEV disease to be reported from New Hampshire in 41 years of national surveillance. The Massachusetts Department of Public Health also reported four cases during August-September 2005. Four of the 11 patients from New Hampshire and Massachusetts died. Patients with aseptic meningitis or encephalitis in areas capable of supporting EEE virus transmission should be tested for EEE, and health-care providers should alert their state health departments when human or animal infection with EEE is suspected. Public health practitioners should advise the public to avoid EEE and other mosquito-borne infections by using personal protective measures (e.g., regular use of insect repellents containing DEET, picaridin, or oil of lemon eucalyptus; wearing long-sleeved shirts and pants when outdoors; and avoiding the outdoors during mosquito biting times). Communities where risk for transmission of EEE virus has been demonstrated should consider establishing mosquito surveillance and control programs.

Travelers to tropical areas should be aware of dengue and reduce their risk for dengue by using mosquito repellent, wearing long sleeve shirts and long pants and taking other actions to avoid mosquitoes.
For the majority
of residents of the United States, the greatest risk for dengue infection
is travel to a tropical or subtropical region of the world where dengue
is endemic. Dengue viral infections are transmitted by
mosquitoes. A mild flu-like illness may result, but severe illness,
even death, can occur. Travelers to tropical areas can reduce their risk
for dengue by using mosquito repellent, wearing long sleeve shirts and
long pants, and taking other actions to avoid mosquitoes.
Health-care providers should consider dengue in the differential diagnosis
of febrile illness in patients who have returned recently from dengue-endemic
areas.
