The U.S. Centers for Disease Control and Prevention (CDC) has issued a nationwide alert due to an increase in rabies exposures and a surge in post-exposure treatment needs. Reports of potential rabies incidents have risen, affecting hundreds across various states.
Rabies Incidents and Advisory
In its September 10 Health Alert Network advisory, the CDC noted a 17% increase in rabies-related inquiries for July and August 2026 compared to the same period last year. At least eight state health departments reported higher usage of post-exposure prophylaxis (PEP) and administration errors.
Although there is currently no shortage of human rabies vaccine or human rabies immunoglobulin in the United States, it is important for clinicians to administer PEP appropriately because errors in rabies risk assessment and PEP administration could result in unnecessary treatment, potential adverse effects, and avoidable costs
Local health departments are managing large exposure events. Notably, in North Carolina, rabid baby goats in a mobile petting zoo exposed hundreds to the virus.
Recent Rabies Cases
The CDC reports a rise in human encounters with potentially rabid animals. Traditional rabies carriers like bats, raccoons, skunks, and foxes have been involved, but less typical sources, such as livestock, are also identified.
In North Carolina, multiple baby goats contracted rabies, likely after being bitten by a rabid skunk. Nearly 300 people potentially interacted with the goats, with over 200 advised to get preventive treatment.
The CDC has not pinpointed a single reason for the national increase. They suggest various factors, including local outbreaks and better reporting, could be contributing.
Symptoms and Treatment of Rabies
Rabies is a viral disease targeting the central nervous system, nearly always fatal after symptoms appear. Early signs resemble the flu, with fever, headache, weakness, or nausea. As the disease progresses, it leads to severe symptoms like confusion, hallucinations, and paralysis.
Treatment must begin before symptoms show. If exposed, individuals receive an immediate assessment. PEP treatment includes cleaning wounds, administering human rabies immune globulin (HRIG), and multiple vaccine doses.
The standard treatment regimen involves four vaccine doses over two weeks. Immunocompromised individuals may need an additional dose and confirmatory tests.
Errors with HRIG and vaccine administration are a concern, given recent increases in demand.
Cost and Side Effects of Rabies Treatment
Treatment costs vary, with full courses of PEP ranging from $11,000 to $14,000. Costs depend on patient weight, location, and insurance. The CDC cautions against unnecessary treatments to manage healthcare system expenses and resources.
Most treatment side effects are mild, such as soreness or swelling at injection sites. Severe reactions are rare, and treatment benefits significantly outweigh risks.
Risky Animals
Bats are significant rabies carriers in the U.S., linked to many human rabies deaths. Raccoons, skunks, and foxes are also common vectors. Domestic animals, such as unvaccinated cats and dogs, and livestock like cattle and goats, can contract rabies from wildlife.
The CDC advises avoidance of direct contact with wildlife and unusual animal behavior to reduce rabies exposure risks.
