Weekly Update

Moisture departure from normal, showing a fairly wet spring for South Dakota, with another map showing a relatively cool spring for much of the state.

We hope that everyone was able to stay warm and dry this winter. Summer is here, and many areas around the state are relatively wet and cooler than normal. Right now, we are experiencing some problems with this website due to a recent update to Drupal that scrambled some files. We hope to be up and running again soon.

Seasonal Report

Seasonal Report

The 2019 Season is just beginning, but initial predictions have been calculated. These early predictions are based on spring and summer weather conditions, as well as the first seasonal mosquito data collected on West Nile Virus. Prediction accuracy will improve as the season progresses and more mosquito data is added. Check back later for more reports on West Nile Virus activity.

South Dakota State University has partnered with the South Dakota Department of Health to implement a program of West Nile virus (WNV) research that will support public health decision makers at the state level and mosquito control programs at the local level. Major activities include mosquito surveillance and testing for WNV, monitoring environmental risk factors using data from earth observing satellites, and using this information to predict the risk of WNV to humans across the state. This work is supported in part by a grant from the NASA Applied Sciences Public Health and Air Quality Program (NNX15AF74G).
