Human enteroviruses and wildlife: isolation from gray squirrels

Area of Science:

• Virology
• Zoonotic Diseases
• Wildlife Health

Background:

• Human echoviruses are a group of enteroviruses known to cause various illnesses.
• Gray squirrels are common urban and suburban wildlife, potentially interacting with humans and domestic animals.

Purpose of the Study:

• To report the detection of human echovirus 1/8 complex in a wildlife population.
• To investigate potential reservoirs for human enteroviruses in non-human hosts.

Main Methods:

• Fecal samples were collected from free-ranging gray squirrels.
• Viral isolation and identification were performed on collected samples.

Main Results:

• Five isolates of the human echovirus 1/8 complex were successfully recovered from squirrel feces.
• The specific origin and transmission routes of these isolates were not identified.

Conclusions:

• Gray squirrels may serve as a potential, yet unconfirmed, reservoir for human echovirus 1/8 complex.
• The public health implications and ecological role of echovirus in this wildlife population require further investigation.
