MARYN MCKENNA: thanks so much for taking my question. Dr. Frieden, you said the CDC expects local transmission of Zika in the United States. Is there anything you can say at this point about the robustness of state and local mosquito control programs?
TOM FRIEDEN: Mosquito control in the U.S. Is often done by what are called mosquito abatement or abatement districts and quite variable. Some of them do a superb job, some of them less so. That’s why it’s so important that we invest in the systems to track and find mosquitos. This is not easy work. And I can — although the mosquitos did spread West Nile having worked on that for many years, the different aspects of mosquito control can be quite complex, labor intensive, and really when it comes to both Zika in general and mosquito control specifically, it is not easy, and it is not quick. For mosquito control, you need to have monitoring of both mosquito larvae and adult mosquito. That’s a labor intensive complex undertaking, and then you need to control mosquito larvae and adult mosquitos, and that’s a labor intensive and challenging area. We know from the experience with dengue, you have to get to very high levels of mosquito control to drive down the risk of dengue in the community.
MARYN MCKENNA: My follow-up question this sounds like something you’re concerned about.
TOM FRIEDEN: Yes, I think it is concerning because of the pregnant women and the developing fetus and because there is such an important need for us to learn more and do more in the U.S., in Puerto Rico and the other territories of the U.S., which have had lots of dengue cases in the past, and that’s a marker for the risk of Zika and around the world. So that we can learn more and partner to address Zika as effectively as possible.
