Emerging Wildlife Diseases
Emerging Wildlife Diseases
The effects of emerging wildlife diseases are global and profound, often resulting in the loss of human lives, economic and agricultural impacts, declines in wildlife populations, and ecological disturbance. The USGS National Wildlife Health Center (NWHC) works to safeguard our Nation’s wildlife from diseases by studying the causes and drivers of these threats and by developing strategies to prevent and manage them.

Avian Influenza
Avian influenza is a viral disease caused by various strains of avian influenza viruses that can be classified as low pathogenic avian influenza (LPAI) or highly pathogenic avian influenza (HPAI). It remains a global disease with potential high consequence with the potential to threaten wildlife, agriculture, and human health.
Marine Invertebrate Diseases
Coral reefs worldwide are under tremendous stress primarily due to human activities along the coasts. While climate change, over fishing, and coastal development have been implicated as a major cause of coral reef decline, diseases seem to play an increasing role.
Sea Turtle Diseases
Sea turtles are one of the oldest groups of reptiles and are found worldwide. There are seven species of sea turtles in the world, and Hawaii has two of them, the hawksbill and the far more numerous green turtle. Threats to turtles include by-catch from fisheries activity, over harvesting of eggs on nesting beaches, and disease. Of the latter, the most significant disease of sea turtles is called...
Snake Fungal Disease
Snake fungal disease is an infectious disease confirmed in numerous species of snakes caused by the fungus Ophidiomyces ophidiicola.
Sylvatic Plague
Sylvatic plague, caused by Yersinia pestis, is a bacterial disease transmitted by fleas that afflicts many mammalian species, including humans.
White-Nose Syndrome
White-nose syndrome (WNS) is an emergent disease of hibernating bats that has spread from the northeastern across United States at an alarming rate.
Vector-Borne Diseases
Vector-borne diseases are transmitted from one animal to another by vectors, including insects, such as mosquitoes or fleas, and arachnids, such as ticks. The USGS National Wildlife Health Center investigates wildlife diseases, including vector-borne diseases, such as West Nile virus and sylvatic plague.
