In general, there is no need. Most people who become infected have few to mild symptoms and are only exposed to those arboviruses that are present in the areas where they live or travel. Testing is not usually done on asymptomatic people, but when a blood or organ recipient or an infant becomes infected with an arbovirus such as WNV, antibody testing may be ordered on the asymptomatic donor or mother to help determine whether she was the source of the infection.
2. Are arboviruses something I should worry about when I travel?
Every region in the world has its own health concerns and it is prudent to read about the areas where you will be traveling and to talk to your doctor about the risks for infection. There is an increased risk of an arbovirus infection when traveling to a tropical location or to an area that has seasonal outbreaks. A person's likelihood of exposure will be influenced by their planned activities and by the preventive measures that they take. (For more on the specific diseases related to your travels, visit the Destinations page on the CDC web site.)
Protection begins with preventing mosquito bites. Measures may include wearing long-sleeved shirts and pants when outdoors, using insect repellent, and staying indoors at dawn and dusk when mosquitoes are most active. Around your home, you can eliminate standing water sources that attract mosquitoes. Communities can take preventive measures by monitoring the seasonal risks and spraying for mosquitoes as warranted.
