Rabies remains one of the world’s most dangerous infectious diseases because, once clinical symptoms begin, it is almost always fatal. The good news is that rabies is preventable when exposure is treated quickly.
Recent CDC surveillance continues to emphasize the importance of rapid evaluation after animal bites, scratches, or other potentially risky contact. CDC data are provisional and can change as reports are reconciled, so any reported short-term increase should be interpreted carefully rather than as proof of a nationwide surge.
What Is Rabies?
Rabies is a viral infection that attacks the central nervous system, including the brain and spinal cord. It is mainly transmitted when saliva from an infected mammal enters the body through a bite, scratch, or an open wound.
In the United States, rabies is most commonly associated with wildlife such as bats, raccoons, skunks, and foxes. Domestic animals can also become infected if they encounter rabid wildlife.
Globally, rabies remains a major public-health concern, particularly in regions where canine rabies is still widespread and access to post-exposure treatment is limited.
Is Rabies Really Increasing?
CDC's National Notifiable Diseases Surveillance System publishes weekly rabies data, but the agency notes that these counts are provisional and subject to change as health departments update their reports.
More importantly, rabies remains relatively uncommon in humans in the United States. CDC reports fewer than 10 human deaths annually in recent years, while approximately 100,000 people receive rabies post-exposure prophylaxis after possible exposure each year.
So, whether the reported 17% figure refers to a particular surveillance dataset, period, location, or category is important before interpreting it as a nationwide rise in human rabies.
The bigger message is clear: even a single potential exposure can be an emergency because treatment is highly effective when given before symptoms develop.
Why Summer and Late Summer Can Increase Concern
Warm-weather months can mean more outdoor activity and greater contact between people, pets and wildlife.
Potential situations include:
- Children playing outdoors
- Hiking and camping
- Encounters with bats
- Dogs or cats roaming outside
- Wildlife entering homes
- Unfamiliar dogs or cats approaching people
- Animal bites occurring while traveling
- People attempting to handle sick or injured wildlife
However, seasonality does not mean that every animal encounter carries rabies risk. A healthcare professional or public-health authority should assess the specific exposure.
Early Symptoms of Rabies
Rabies symptoms usually do not appear immediately after exposure. The incubation period can last weeks to months and varies according to factors such as the exposure site and severity.
Early symptoms may include:
- Fever
- Headache
- Weakness
- General discomfort
- Tingling, itching or unusual sensations around the bite site
Because these symptoms can resemble many ordinary illnesses, the history of an animal bite or exposure is extremely important.
Advanced Rabies Symptoms
As the infection progresses to the nervous system, symptoms can become severe.
Possible neurological symptoms include:
- Anxiety and agitation
- Confusion
- Insomnia
- Delirium
- Hallucinations
- Difficulty swallowing
- Excessive salivation
- Hydrophobia, or fear of water
- Seizures
- Progressive neurological dysfunction
CDC notes that severe disease generally develops rapidly after the initial symptoms begin. Once clinical signs appear, rabies is nearly always fatal.
That is why waiting for symptoms after a potentially dangerous animal exposure is not safe.
What Should You Do After an Animal Bite or Scratch?
If you are bitten or scratched by an animal that could have rabies, take action immediately.
1. Wash the wound
Immediately wash the wound thoroughly with soap and running water for about 15 minutes.
Wound cleaning can help remove virus from the exposed area and is an important first step.
2. Seek medical advice urgently
Contact a healthcare professional or local public-health authority as soon as possible.
Do not wait for symptoms to appear.
3. Report important details
Be prepared to explain:
- What animal was involved
- Whether it was wild or domestic
- Whether the animal was acting strangely
- Where the incident occurred
- Whether the animal bit or scratched you
- Whether saliva contacted broken skin, eyes or mouth
- Whether the animal is available for observation or testing
- Whether your own pet is vaccinated
These details help professionals determine whether rabies treatment is necessary.
What Is Rabies Post-Exposure Prophylaxis?
Post-exposure prophylaxis (PEP) is medical treatment given after a potential rabies exposure to prevent the virus from causing disease.
For people who have not previously received rabies vaccination, CDC's current PEP guidance includes:
- Immediate wound care
- Human rabies immune globulin (HRIG)
- A four-dose rabies vaccine series
The exact treatment can differ depending on previous vaccination and certain medical circumstances.
PEP should be started as soon as medically indicated after a potential exposure.
Can Rabies Be Prevented?
Yes. Several simple precautions can dramatically reduce the risk.
Keep pets vaccinated
Regular rabies vaccination of dogs, cats and other eligible pets is one of the most important prevention measures.
Vaccinated pets are also less likely to become infected after encountering wildlife.
Avoid wild animals
Never approach or attempt to touch wildlife that appears sick, injured, unusually aggressive, unusually tame or active at an unusual time.
This is particularly important with bats, raccoons, skunks and foxes.
Teach children animal safety
Children should learn never to:
- Approach unfamiliar animals
- Touch wild animals
- Pick up bats
- Disturb animals that appear sick
- Play with stray dogs or cats
- Put their hands near an unfamiliar animal's mouth
Protect your home
Keep pets supervised outdoors and prevent wildlife from entering buildings whenever possible.
Consider vaccination before exposure when appropriate
People who regularly work with potentially rabid animals, including certain veterinarians, wildlife professionals and animal-control workers, may be candidates for pre-exposure rabies vaccination. Certain travelers visiting areas where canine rabies is common may also benefit from pre-exposure vaccination.
Why Bat Encounters Deserve Special Attention
A bat bite may be tiny and difficult to notice.
CDC has highlighted cases in which people died after bat encounters because they did not recognize the potential exposure or seek medical evaluation and PEP.
If a bat has been in a room with a sleeping person, young child, or someone who may not be able to reliably report contact, professional advice is particularly important.
Never handle a potentially rabid bat with bare hands.
Rabies Prevention: The Most Important Takeaway
Rabies is frightening because of its severity, but it is also an unusual disease in that timely prevention after exposure can stop the infection before it becomes deadly.
Remember these five steps:
- Avoid unfamiliar and wild animals.
- Keep pets' rabies vaccinations up to date.
- Wash bites and scratches immediately with soap and water.
- Contact a healthcare professional or public-health authority promptly.
- Never wait for rabies symptoms before seeking advice after a risky exposure.
CDC currently reports that rabies remains rare as a human disease in the United States, but thousands of animal rabies infections occur annually and roughly 100,000 people receive PEP following potential exposure.
Final Thoughts
Whether a particular surveillance period shows a 17% increase or another short-term change, rabies prevention should remain a priority. The danger is not simply the number of reported cases—it is the fact that once symptoms develop, treatment options are extremely limited.
The safest response to a suspicious animal bite, scratch or exposure is simple: wash the area immediately and seek professional medical assessment without delay.
