CDC Alerts Public to Rising Rabies Exposures Amid Summer Spike

The Centers for Disease Control and Prevention (CDC) has issued a public health advisory concerning a notable increase in rabies exposures across the United States this summer. The alert, disseminated through the CDC's Health Alert Network, emphasizes the importance of timely vaccination and treatment following exposure to potentially rabid animals.

Increased Rabies Cases and Human Exposures

The CDC's warning follows a recent incident in North Carolina, where three baby goats at a mobile petting zoo tested positive for rabies. This exposure potentially affected hundreds of individuals, leading the state health department to recommend rabies vaccinations for over 260 people. The goats, which were too young to be vaccinated, were bitten by a rabid skunk, prompting their euthanasia to prevent further spread.

Rabies, a rare but deadly viral disease, is primarily transmitted through bites or scratches from infected animals. In the U.S., raccoons, skunks, bats, and foxes are common carriers. The CDC highlighted that not receiving post-exposure prophylaxis (PEP) before symptom onset can result in severe brain disease and death.

Preventive Measures and Public Guidance

The CDC's advisory urges the public to avoid contact with wildlife and seek immediate medical care if bitten or scratched by an animal. People are also advised to keep pets up-to-date on rabies vaccinations and to maintain a safe distance from sick or injured animals. In case of an animal bite, washing the wound with soap and water is recommended as a first response.

From July to August, the CDC recorded a 17% increase in rabies-related inquiries compared to the previous year. At least eight state health departments reported a higher use of rabies vaccines and noted errors in PEP administration. Despite the increased exposures, fewer than 10 people die from rabies annually in the U.S., thanks to effective pet vaccinations and animal control programs.

Case Example: Concerned Parents in North Carolina

Rebecca Lanning, whose family visited a petting zoo in Mocksville, North Carolina, expressed shock upon learning that her 4-year-old son had been exposed to rabies. The petting zoo featured the goats that later tested positive for the virus. Lanning promptly sought medical treatment for her son, initiating the rabies vaccine series. "My fear is that if he was feeding the goats, and he's 4. Who's to say that he didn't touch his mouth or eyes?" she remarked, highlighting the anxiety faced by parents in such situations.

The CDC's advisory underscores the critical nature of rabies risk assessments and adherence to evidence-based recommendations for administering PEP. The treatment typically involves a dose of human rabies immune globulin and at least four doses of a rabies vaccine, which is nearly 100% effective if given promptly.
