Zika Zone USA

Be aware and prepare!

Update from the team

ZikaZoneUSA map production has hibernated for the Northern Hemisphere and will return in spring. The beta test has reached its successful conclusion. Due to the overwhelming response we will continue to develop the product and will publicly release future updates as they become available. We have left 3 maps in place to showcase some of last year’s updates. We wish to thank the thousands of people who contacted our team with concerns, questions, and suggestions.

According to Dr. Freiden, CDC director, the diseases (Zika and dengue) transmitted by the Aedes aegypti may become endemic because these are not controllable with current technologies. This trend may continue in the U.S. Our expectation is that Zika and the Aedes aegypti mosquito will continue to take hold in the US where conditions exist for its annual survival. Zika Zone USA was purposefully developed to identify these conditions. Estimates on a vaccine vary greatly, and are anywhere from 2 to possibly 10 years.

2017 will be an important year for you to consider your response to anticipated Zika conditions. It is for this reason we are taking this important time to incorporate the information we have received and update the product to better protect the public from this threat.

To all the physicians, scientists, public health officials, health workers and consumer product advocates, private companies, and governments large and small, we would like you to know that your input has been received, and we will incorporate that material and experience in the future release of the Zika Zone product suite.

Are you in a Zika Zone?

Recently published research shows that the Aedes aegypti mosquito, the primary vector for Zika Virus, is more effective at biting when the environmental conditions are favorable. The Zika Zone JV team has applied the best available research and the power of cloud-computing to create experimental weekly maps that show where conditions are prime for the Zika-spreading mosquito to breed, bite, and potentially infect humans with the Zika virus.

The map is just a click away

But first, a word from our lawyer: by showing the map, you confirm that you agree to our Terms of Use .

What the maps show

  • Each analysis is for the week ending on the date listed with each map. The areas highlighted are where our analysis has identified as being most suitable for the Aedes aegypti.
  • The maps show colors increasing from yellow to red, indicating increasingly favorable environmental conditions for the Aedes aegypti mosquito. The reddest areas show where the environmental conditions were highly favorable. Unshaded areas indicate where conditions were less suitable.
  • A measurement of how favorable the environmental conditions are according to the best available research, approximately within the CDC's estimated Aedes aegypti range. As additional research is performed on this emerging threat, we will update our maps.

What the maps do not show

  • These maps are based solely on where the conditions are likely suitable for the Aedes aegypti mosquito. This is not necessarily an indication that the Aedes aegypti mosquito is actually present in these locations.
  • Moreover, if the Aedes aegypti mosquito does exist in an area identified, this map is not necessarily an indication that the mosquitos in this area carry Zika.

Stay informed about the only scientifically-developed map that identifies current Zika Zones across the United States

We are currently testing neighborhood Zika Zone maps and alerts for your area. We intend to make the US-scale map freely available for the duration of our beta, and in the future, potentially offer a suite of neighborhood-scale products available for a small subscription fee. If you are interested in the Zika Zone products, please sign up below and you'll be the first to know when we make them available.

What is Zika?

Zika is a virus that can spread between humans from the bite of an infected mosquito, the Aedes aegypti. A pregnant mother can transmit the virus to her fetus.

Symptoms of Zika

The symptoms and signs of Zika are mild - fever, rash, joint pain, and red eyes. Because Zika tends to be a mild disease in adults, infected people may not realize that they carry the virus. However, this virus may cause a serious birth defect known as microcephaly and other fetal brain defects. In a small proportion of infections, Zika may trigger Guillain-Barré syndrome, an uncommon sickness of the nervous system.

Person applying insect repellent to arm


There is no vaccine to prevent Zika. Avoiding bites from the Aedes aegypti mosquito will help prevent getting the disease. Two ways to prevent mosquito bites are to use insect repellent and to control mosquito breeding sites inside or outside your home. If you are traveling, know if there is high risk of Aedes aegypti mosquito in the area. The best defense is insect repellent and knowledge!
