Rabies in Wildlife Raises Public Health Concerns

Officials are warning about the rise of rabies among wildlife, which is posing a significant public health threat. According to estimates, around 75% of Americans come into contact with raccoons, skunks, and foxes—animals known to transmit deadly diseases, as highlighted by the Centers for Disease Control and Prevention (CDC).

The CDC’s latest report from the National Rabies Surveillance System indicates a 5% increase in wildlife rabies cases in 2023 compared to the previous year. “The CDC is currently tracking 15 rabies outbreak situations,” said Paul Prince, a spokesperson for the CDC. “There may be more outbreaks, but those are often managed locally.”

This summer, Nassau County in New York issued a public health warning after observing 22 rabies cases this year, a sharp increase from just six last year—over three times the previous count.

Alyssa Zorabian, director of Nassau County Communications, remarked, “These reports indicate a troubling resurgence of terrestrial rabies that was largely controlled with intervention strategies since 2016.”

Understanding Rabies

Rabies is a virus that spreads to humans through bites or wounds from infected animals. Symptoms can take weeks or even months to manifest, showing up only after the virus affects the brain and spinal cord. Initial signs can feel like flu symptoms—fever, headache, and fatigue—although pain and numbness at the bite site are also key indicators.

More severe symptoms may appear within two weeks, leading to confusion, agitation, and hallucinations. “Classic symptoms include intense thirst and a paradoxical fear of water, alongside excessive drooling and occasionally aggressive behaviors,” noted experts. Unfortunately, rabies is nearly always fatal once symptoms appear, but it is almost completely preventable when addressed early.

After a potential rabies exposure, it’s crucial for individuals to seek quick medical attention, known as post-exposure treatment, which may include neutralizing antibodies.

Why the Rise in Cases?

Experts suggest that increased human interaction with wild animals, particularly through relocation practices, is contributing to a rise in rabies cases. Dr. Edward R. Rensimer, an infectious disease expert, stated, “Some states are boosting funding for placing rabies vaccines in the environment.”

The Nassau County Health Department initiated a rabies vaccine bait program this fall, with additional distributions planned for the spring and fall of next year. “If animal control and prevention efforts are scaled back, we could see a tragic increase in rabies presence among wildlife,” warned Aaron Gratt, chief of infectious diseases at Sinai Southern Nassau Mountain Hospital.

Fortunately, human rabies cases remain rare, with a few reported deaths annually. Last year, the CDC noted six rabies-related deaths in the U.S., with two more reported in 2025. The CDC emphasized that while recent cases do not signify a widespread outbreak, they serve as a reminder of the persistent public health risk rabies poses.

Animals at Risk

Wild animals are responsible for over 90% of rabies cases in the U.S. People living in eastern regions are at higher risk from raccoons, while skunks and foxes are prevalent threats in other areas like the Midwest and Southwest.

The CDC’s spokesperson mentioned, “More than 30 unique rabies virus variants exist in the U.S., each associated with specific wildlife.” Rabies incidents have surged in areas like Kentucky and Arizona recently, and the virus is present in wildlife across all states except Hawaii.

Pets and Rabies

Though rabies cases in pets are relatively low, they can still occur. “Pets mostly indoors seem safer, but wildlife can easily access yards or homes,” cautioned a CDC representative. Stray animals, including a dog and two cats recently found rabid in Philadelphia, highlight the risk. Regular vaccination is essential for pets to safeguard them and their owners from rabies.

The Nassau County Department of Health is actively collaborating with local authorities to provide free rabies vaccinations for pets on September 13th. Gratt concluded firmly, “The best way to prevent rabies is simply to avoid wildlife.”
