Interview Transcript (slightly modified for readability)

“The CDC and WHO have very good websites where they list advice [on how to protect oneself against Zika virus infection]. Clearly, the advice remains that pregnant women should avoid traveling to currently Zika-infected countries. For non-pregnant women and men traveling to Zika-infected areas, the usual precautions still count, which is daytime protection [from] mosquitoes that are responsible for Dengue, Zika, and Chikungunya, mainly during the day.

Of course you can reduce landing and biting rates with personal protection, like spraying [mosquito repellant] and [wearing] long-sleeves, etc. But we have not seen any data that good personal protection, indeed, also translates to less disease.”
