The U.S. Centers for Disease Control and Prevention (CDC) has released a health advisory, warning of a rise in rabies exposures and increased use of post-exposure treatment. Recent incidents involving potentially rabid animals affected individuals across several states.
According to the CDC’s September 10 Health Alert Network advisory, rabies-related inquiries increased by 17% in July and August 2026 compared to the previous year. Eight state health departments reported a spike in rabies post-exposure prophylaxis (PEP) use and some administration errors.
The CDC highlights that there is no shortage of rabies vaccines or immunoglobulin in the U.S., but proper PEP administration is crucial to avoid unnecessary treatment, negative effects, and extra costs.
Local health departments are addressing a series of major exposure events, including a North Carolina outbreak linked to rabid baby goats from a mobile petting zoo. Hundreds of people might have been exposed.
Rabies Cases Surge in U.S.: Current Situation
Reports from across the nation indicate an increase in human exposure to rabid animals. Traditional rabies carriers like bats, raccoons, skunks, and foxes, along with less common carriers, have been involved.
A significant exposure event in North Carolina involved baby goats testing positive for rabies after contact at various events. Around 300 people were evaluated, with over 200 advised to undergo treatment.
The goats were infected after being bitten by a rabid skunk and had not been vaccinated. Despite increased exposures and treatment demand, the CDC found no single cause for the nationwide trend but pointed to multiple local outbreaks. Factors like public awareness, testing, and infected wildlife spikes may contribute.
Understanding Rabies Symptoms
Rabies attacks the central nervous system and is almost always fatal after symptoms begin. Yet, it is preventable with early treatment.
Initial symptoms resemble other illnesses, including fever, headache, weakness, fatigue, nausea, and sore throat. These nonspecific symptoms might delay recognizing a life-threatening infection.
As rabies progresses, symptoms worsen, with confusion, hallucinations, difficulty swallowing, excessive salivation, paralysis, and coma. Once neurological symptoms appear, the disease is generally fatal despite intensive care.
Rabies Treatment for Humans
Timely treatment is vital. After exposure, health officials assess risk based on the animal type and contact nature.
If warranted, patients receive rabies post-exposure prophylaxis (PEP). Treatment starts with immediate wound cleaning followed by human rabies immune globulin (HRIG) and a vaccine series.
Typically, four vaccine doses are given over two weeks. Immunocompromised individuals might need a fifth dose and more testing for immune response.
Proper HRIG and vaccine administration is essential, especially with increased treatment demand raising concerns about dosing errors. Side effects are mostly mild, such as soreness, redness, or swelling at the injection site, headache, fatigue, nausea, and muscle aches.
Serious reactions are rare, and the benefits of treatment outweigh risks since rabies is nearly always fatal post-symptoms.
Rabies Treatment Costs
Rabies treatment is costly, involving immune globulin and several vaccine doses. Costs vary by location, insurance, and immune globulin volume required, which depends on patient weight. A full PEP course can range from $11,000 to $14,000 per person, according to the CDC.
The CDC advisory points to concerns over inappropriate treatment delaying costs and straining rabies biologic supplies. Officials stress that cost concerns should not deter medical evaluation after exposure.
Animals with the Highest Rabies Risk
Bats are a major rabies source in the U.S., linked to recent human rabies deaths, often when bites were unnoticed.
Other wildlife associated with rabies include raccoons, skunks, and foxes, serving as rabies reservoirs regionally. Domestic animals like cats contract rabies more than dogs, although pet vaccination programs reduce risks. Livestock like cattle, horses, and goats can be infected after exposure to rabid wildlife.
The CDC advises avoiding direct contact with wildlife or any mammal acting unusually. Prompt evaluation is crucial after any potential exposure, as rabid animals don’t always show visible sickness.
