Rabies Exposure on the Rise: CDC Issues Health Advisory

CDC’s Alert on Rabies Exposure

The Centers for Disease Control and Prevention (CDC) has issued a nationwide health advisory regarding the increase in rabies exposures across various states. The advisory highlights a significant rise in rabies-related inquiries and post-exposure treatments, following several high-profile incidents involving potentially rabid animals.

In the CDC’s Health Alert Network advisory from September 10, the agency reported a 17% increase in rabies-related inquiries during July and August 2026 compared to the previous year. Additionally, eight state health departments have reported a rise in rabies post-exposure prophylaxis (PEP) usage and administration errors.

“There is no current shortage of human rabies vaccine or immunoglobulin in the United States, yet it is crucial for clinicians to administer PEP correctly. Errors can lead to unnecessary treatments, adverse effects, and avoidable costs.” – CDC

Large Exposure Events

Local health departments are addressing a series of unusual exposure events, including a North Carolina outbreak caused by rabid baby goats traveling with a mobile petting zoo. This outbreak potentially exposed hundreds of individuals. The goats were believed to be bitten by a rabid skunk before testing positive for rabies.

State health officials assessed nearly 300 individuals who may have interacted with the infected goats, recommending post-exposure treatment for over 200 people. The incident attracted national attention due to the large number of potential exposures.

Understanding the Increase

The CDC confirmed the uptick in exposures and treatment demand but pointed to multiple local outbreaks rather than a single cause. Factors such as increased public awareness, testing, reporting, and localized wildlife infection spikes may contribute to the rise.

Rabies Symptoms

Rabies affects the central nervous system and is typically fatal once symptoms develop. Early signs can mimic other illnesses, including fever, headache, weakness, and nausea. As rabies progresses, symptoms become severe, leading to confusion, anxiety, hallucinations, and paralysis. Once neurological symptoms appear, rabies is nearly always fatal.

Treatment for Rabies Exposures

Timely treatment is essential for preventing rabies. After potential exposure, an assessment determines the need for rabies post-exposure prophylaxis (PEP). PEP involves immediate wound cleaning, administration of human rabies immune globulin (HRIG) for immediate antibodies, and a series of rabies vaccine doses.

Typically, treatment includes four vaccine doses over two weeks. Immunocompromised individuals may need a fifth dose and further testing to ensure adequate immune response. Proper administration is critical, with recent treatment demand raising concerns about potential dosing errors.

Side Effects and Costs

While rabies treatment can be lifesaving, side effects are possible. Mild reactions may involve soreness, redness, or swelling at the injection site, along with headache, fatigue, or muscle aches. Serious adverse effects are rare, and the benefits usually outweigh the risks.

Rabies treatment can be costly, with expenses ranging from $11,000 to $14,000 per person. Costs vary based on location, insurance, and immune globulin amount needed. The CDC advises prioritizing treatment despite concerns about expense or inappropriate use.

Animals With Rabies Risk

In the U.S., bats are a significant source of human rabies infections, often linked to unrecognized bites. Other common rabies carriers include raccoons, skunks, and foxes. Domestic animals like cats, dogs, and livestock can be infected if bitten.

Health officials recommend avoiding contact with wildlife and any unusual mammal behavior. Prompt medical evaluation is crucial after potential exposure, given that rabid animals may not always appear sick.
