Traveling Overseas? 

Mosquito bites are bothersome enough, but when you consider risks, like getting sick with Zika, dengue, chikungunya or other mosquito-borne illness, its important to protect yourself and your family when traveling overseas. 

Avoid Mosquito Bites

  • Research your travel destination: Learn about country-specific travel advice, health risks, and how to stay safe by visiting CDC Travelers' Health website.
  • Use insect repellent: Use an Environmental Protection Agency (EPA)-registered insect repellent. When used as directed, EPA-registered insect repellents are proven safe and effective, even for pregnant and breastfeeding women.
  • Cover up: Wear long-sleeved shirts and long pants.
  • Keep mosquitoes outside: Stay in places with air conditioning or that use window and door screens. If you are not able to protect yourself from mosquitoes inside your home or hotel, sleep under a mosquito bed net.

After Your Trip

Visit your healthcare provider right away if you develop a fever, headache, rash, muscle or joint pain.

  • Tell your doctor about recent international travel.
  • Visit the CDC's Getting Sick after Travel webpage for more information.

Surveillance for Vector-Borne Diseases, Active and Reserve Component Service Members, U.S. Armed Forces, 2010 – 2016

Within the U.S. Armed Forces considerable effort has been applied to the prevention and treatment of vector-borne diseases. A key component of that effort has been the surveillance of vector-borne diseases to inform the steps needed to identify where and when threats exist and to evaluate the impact of preventive measures. This report summarizes available health records information about the occurrence of vector-borne infectious diseases among members of the U.S. Armed Forces, during a recent 7-year surveillance period. For the 7-surveillance period, there were 1,436 confirmed cases of vector-borne diseases, 536 possible cases, and 8,667 suspected cases among service members of the active and reserve components. •	“Confirmed” case = confirmed reportable medical event. •	“Possible” case = hospitalization with a diagnosis for a vector-borne disease. •	“Suspected” case = either a non-confirmed reportable medical event or an outpatient medical encounter with a diagnosis of a vector-borne disease. Lyme disease (n=721) and malaria (n=346) were the most common diagnoses among confirmed and possible cases. •	In 2015, the annual numbers of confirmed case of Lyme disease were the fewest reported during the surveillance period. •	Diagnoses of Chikungunya (CHIK) and Zika (ZIKV) were elevated in the years following their respective entries into the Western Hemisphere: CHIK (2014 and 2015); ZIKV (2016). The available data reinforce the need for continued emphasis on the multidisciplinary preventive measures necessary to counter the ever-present threat of vector-borne disease. Access the full report in the February 2018 MSMR (Vol. 25, No. 2). Go to  Background graphic shows service member in the field and insects which spread vector borne diseases.

Chikungunya Infection Among MHS Beneficiaries in the Western Hemisphere

the Disease Reporting System Internet (DRSi). It also describes signs and symptoms of Chikungunya infection.  As of February 2015 there have been 121 Chikungunya (CHIK) cases among DoD healthcare beneficiaries reported through the DRSI. Chikungunya fever is caused by infection with the CHIKV an alphavirus of the Togavirdae family. All DoD Cases were contracted OCONUS.  Just the facts  •	Since 2013, 46 countries or territories in the Americas have reported 2,006,363 chikungunya cases. •	The CDC has not reported new imported CHIKV cases in the United States since January 12, 2016. •	The virus is commonly transmitted to people via the bite of an infected mosquito of the genus Aedes (A. Aegypti or A. albopictus). •	Long lasting immunity seems to result after recovery from the infection but there is no vaccine available to prevent illness due to CHIKV infection.
