There is currently no evidence that Zika causes more serious illnesses in the elderly or people with chronic illnesses. It is recommended that all travelers consult with their healthcare providers to be sure they are well enough to travel. In most cases, the Zika virus causes a mild illness. Providers should consider the patient's ability to withstand all vector‐borne diseases, including but not limited to dengue, Chikungunya, and malaria, which can cause severe illness. Other travel-related illnesses, such as diarrhea should also be considered. If a person chooses to travel, they should take steps to avoid mosquito bites. Please review the question, "Can I travel to countries affected by the outbreak?" for more information.
