The USGS National Wildlife Health Center developed WHISPers, a partner driven tool that provides a dynamic, timely, searchable web-based system, to increase public awareness of wildlife disease events and promote collaboration and data sharing among wildlife professionals. This is a screen shot of the web-based tool. 

Reported distribution of chronic wasting disease (CWD) in North America in 2017: 24 States and 2 Canadian Provinces have reported the disease in free-ranging and captive cervids.

This microscopic image shows a sun-shaped area within turtle skin cells where chelonid herpesvirus 5 replicates. The virus capsids, or protein shells, are arrayed like a corona around the circle. ChHV5 is associated with fibropapillomatosisa tumor disease affecting endangered green turtles.

This image shows the blue version of sylvatic plague vaccine bait for prairie dogs. 

Prairie dogs in the wild are less likely to succumb to a deadly disease called sylvatic plague after they ingest peanut-butter-flavored bait that contains a vaccine against the disease.

The arrows in this image point to mouths of individual corallimorphs, which are a type of invasive anemone that typically thrives in coral reefs that have been degraded by environmental or man-made disturbances. Each corallimorph mouth is surrounded by a corona of tentacles.

Healthy elkhorn coral (Acropora palmata) on the seafloor along the southeastern coast of Buck Island, U.S. Virgin Islands. Elkhorn coral is one of many important reef-building species that create 3D structure on the seafloor. Coral reef structure provides habitat for marine life and helps break up waves as they approach the coastline.

Coral reefs are prone to phase shifts where they quickly transition from coral-dominated to a uniformity of other organisms, typically algae. The Palmyra Atoll National Wildlife Refuge in the Central Pacific is a unique case where a transition from corals to corallimorphs occurred.

Tables are placed below bat boxes to collect guano from roosting bats during spring/summer. NWHC is investigating use of community guano samples from summer roosts for Pseudogymnoascus destructans (Pd) surveillance.

Here a scientist is measuring the length of the forearm of a bat captured in Dane County, Wisconsin. General morphometric data are collected from each bat captured.

Vampire bats (Desmodus rotundus) are the primary spreader of rabies, a lethal disease that harms livestock and people across Latin America, where this bat lives.
