Rabies Is Still Rare. The Exposure Spike Is Real.
A CDC advisory is drawing attention to a summer surge in rabies-related calls, treatment and treatment errors. The signal is serious—but it is not the same thing as a nationwide wave of human rabies.
The most important sentence in the federal government's new rabies advisory may be the least dramatic one: the United States is seeing more reports of people being exposed to rabid or possibly rabid animals, more demand for post-exposure treatment, and more mistakes in how that treatment is given. That does not mean the country is suddenly experiencing a large outbreak of human rabies. Human infection remains extremely rare.
But rare is not the same as trivial. Rabies is one of the clearest examples in medicine of a disease where timing changes everything. Once clinical symptoms begin, rabies is almost always fatal. Before symptoms begin, however, the infection can be prevented with careful wound care and correctly administered post-exposure prophylaxis, or PEP. That is why the Centers for Disease Control and Prevention issued a Health Alert Network advisory on September 10: the pressure point is not only the virus itself, but the chain of decisions that follows a possible exposure.
This summer supplied several reminders of how complicated that chain can become. A mobile petting zoo in North Carolina carried baby goats later confirmed to have rabies to events attended by children and older adults. Counties from New York to Nebraska reported unusually frequent bat encounters. Parks and communities dealt with rabid bats, foxes, beavers and other mammals. Each event set off the same urgent questions: Was there actually an exposure? Can the animal be tested or observed? Does a patient need PEP? If so, was the immune globulin put in the right place, was vaccine given in the right site, and is the schedule correct?
What the CDC alert actually says
From July through August 2026, the CDC says it received 17% more rabies-related inquiries than it did during the same two months in 2025. Those inquiries included reports of events in which more than one person may have been exposed. At least eight state health departments also reported increased PEP use, errors in PEP administration, or both.
The pharmacy data are even more striking. As of September 2, use of the two rabies vaccines licensed in the United States was estimated to be 33% higher than during the comparable period a year earlier, while use of the two licensed human rabies immune globulin products was up an estimated 76%. Those figures describe medical response, not confirmed infections. They can rise because more people are encountering suspect animals, because a single event exposes many people, because clinicians are treating more cautiously, or because local animal activity has changed.
CDC's advisory does not report a corresponding surge in human rabies cases. The agency's broader surveillance materials say fewer than 10 human cases are typically reported in the United States each year, while roughly 100,000 people receive PEP after a potential exposure. In other words, prevention is deliberately much more common than disease.
Calls, exposure assessments and preventive treatment
The advisory documents increased activity around suspected exposure and PEP. That is a public-health workload signal.
A nationwide surge in human rabies disease
CDC did not say the 17% increase in inquiries represents a 17% increase in human infections. The categories are not interchangeable.
Why this summer felt different
Rabies risk is often imagined as a single dramatic bite from a visibly sick wild animal. Public-health investigations are rarely that simple. Some of the highest-profile 2026 events involved settings where people had every reason to think contact was routine: a petting zoo, a park, a bedroom where a bat appeared overnight, a backyard where a pet tangled with wildlife.
North Carolina's mobile petting-zoo investigation shows how quickly one animal-health event can become a human-exposure problem. State health officials confirmed rabies in three baby goats and treated a fourth goat as infected. The goats were believed to have been exposed after a skunk entered their pen in late July. Between July 28 and August 27, the animals traveled to public and private events across multiple counties, including gatherings involving children and older adults.
The risk was not simply that someone might have been bitten. Baby goats are commonly bottle-fed, carried, hugged and handled around the face. Rabies virus is transmitted through saliva when it enters a bite or scratch, broken skin, or mucous membranes such as the eyes, nose or mouth. That meant health officials had to reconstruct who touched the goats, how close the contact was, and whether saliva exposure was plausible. North Carolina even created a public risk-assessment tool to help attendees think through those details while continuing to direct potentially exposed people to local health officials.
Multiple events across several counties created a large tracing and risk-assessment job for health departments.
Erie County said it approved 150 people for PEP in July, its highest total ever recorded for that month.
State tracking listed positive bats in multiple counties through the summer and into September.
Bat season adds another layer. Bats can enter homes through very small openings, and their bites may be difficult to see. CDC advises people to avoid handling bats and to contact public-health authorities after possible direct contact. If a bat is found in a home after possible exposure, officials may recommend safely capturing it for testing rather than simply releasing it. A negative test can spare people from unnecessary PEP; a positive result can clarify that treatment is warranted.
At the same time, public-health agencies have repeatedly stressed that bats are ecologically important and that the correct response is not to kill bats indiscriminately. Rabies prevention is about reducing risky contact, not treating wildlife itself as an enemy.
The decision begins with exposure, not fear
A person who sees a raccoon on the other side of a yard has not had the same event as a person bitten by a raccoon that cannot be captured. Someone who pets a healthy dog that remains available for observation has not had the same event as someone who wakes up with a bat in a room and cannot be certain whether contact occurred. Rabies decisions are specific to the facts.
CDC tells clinicians to consider the animal species, the circumstances of the encounter, whether the animal showed behavior or illness compatible with rabies, the type and severity of any wound, and local epidemiology. Public-health officials are particularly useful because rabies patterns vary by geography. CDC says rabid bats are found in every U.S. state except Hawaii, while raccoon, skunk and fox rabies patterns vary by region.
Separate contact from exposure
Seeing or being near an animal is not enough by itself. Officials look for a bite, scratch, saliva contact with broken skin or mucous membranes, or another credible route of transmission.
Identify the animal and location
Species and geography change the baseline risk. A local health department knows which rabies variants and animal cases are circulating nearby.
Ask whether the animal can be tested or observed
When testing is negative or a health official determines the situation does not pose a rabies risk, PEP may not be recommended. Certain domestic animals can sometimes be observed under established protocols.
Act quickly when risk is credible
Because prevention must occur before symptoms start, suspected exposures deserve prompt medical and public-health attention rather than watchful waiting at home.
When PEP is needed, the details matter
For people who have not previously received rabies vaccination, the standard U.S. PEP regimen has three parts: immediate wound care, a one-time dose of human rabies immune globulin, and a series of rabies vaccinations. CDC's September guidance says the vaccine is given on days 0, 3, 7 and 14. People with certain immune-compromising conditions generally receive an additional dose on day 28 and may need laboratory testing to confirm an adequate immune response.
For previously vaccinated people, the regimen is different: they generally receive vaccine on days 0 and 3 and should not receive human rabies immune globulin. That distinction is one reason clinicians need an accurate vaccination history before ordering treatment.
The immune globulin is not merely an extra shot. For a previously unvaccinated patient, CDC says it should be infiltrated into and around every identifiable wound as anatomically feasible, with any remaining amount given in a different muscle site from the vaccine. The first vaccine and immune globulin should never be mixed in the same syringe or placed in the same anatomical site. Rabies vaccine should not be given in the buttock; a dose placed there is not considered valid and must be repeated at an appropriate site.
PEP, simplified for a previously unvaccinated patient
Wash wounds immediately and thoroughly with soap and water. CDC advises about 15 minutes of washing for the public after a possible exposure.
Given once at the start of PEP, with as much as anatomically feasible infiltrated into and around the wound.
Four doses on days 0, 3, 7 and 14 in the recommended muscle site; an additional dose may be needed for immunocompromised patients.
CDC listed a series of errors it has seen: giving vaccine in the gluteal area, failing to put immune globulin into and around wounds, placing immune globulin and vaccine in the same anatomical site, omitting immune globulin when it is indicated, giving immune globulin to someone who was already vaccinated, misclassifying a patient's vaccination or immune status, using the wrong schedule, and unnecessarily restarting a vaccine series after a timing deviation.
That last point is easy to miss. A delayed dose does not automatically mean the entire sequence must start over. CDC says deviations of a few days are generally not a concern, while longer gaps should trigger consultation with public health. The agency also launched a PEP calculator that lets clinicians enter actual vaccination dates and check the remaining schedule against federal recommendations.
The public-health challenge is not simply to give more shots. It is to give the right treatment to the right person, at the right sites, on the right schedule.
The hidden problem: cost, access and overtreatment
Rabies prevention succeeds because the system treats credible exposure before symptoms appear. That preventive bias is appropriate, but it creates a difficult economic problem when the exposure itself is uncertain. CDC says a typical course of PEP can cost between $11,000 and $14,000 per person. The exact amount a patient owes depends on insurance, where the treatment is delivered, billing practices and whether assistance programs apply.
Those costs help explain why health departments spend so much time on exposure assessment. A negative animal test or a reliable observation period can sometimes eliminate the need for treatment. Conversely, a true high-risk exposure should not be delayed because a patient is worried about price. Some states and local jurisdictions provide pathways to assistance for uninsured or underinsured patients; North Carolina, for example, maintains a patient-assistance program that can provide replacement vaccine and immune globulin through participating health departments and providers when eligibility criteria are met.
The summer's increase in biologic use also matters at the supply-chain level. CDC said there was no national shortage of rabies vaccine or human rabies immune globulin when it issued the advisory. Still, the agency asked health departments to monitor supplies and make sure procurement processes are ready in case allocation limits are needed. The larger message is that unnecessary PEP is not harmless from a system perspective: it carries cost, potential adverse effects and pressure on finite medical inventory.

Why careful assessment saves both lives and resources
Too little treatment after a true exposure can be catastrophic. Too much treatment after a low-risk encounter can burden families and public programs. Testing, observation and local epidemiology help narrow that gap.
Pets remain part of the human safety net
Many human rabies investigations begin with an animal encounter that happens one step removed from a person: a dog kills a skunk, a cat carries a bat into a house, or livestock encounter infected wildlife. Keeping pets current on rabies vaccination reduces the chance that a wildlife event becomes a much larger household emergency.
That point came into focus in San Antonio in August, when local officials reported that an owned dog tested positive for rabies after the dog had killed a baby skunk in late July. The owner had not reported the wildlife encounter. Weeks later, the dog developed concerning behavioral and neurological symptoms, and exposed people and animals had to be evaluated. The event illustrates why veterinary guidance after wildlife contact matters even when the pet appears fine at first.
Rabies incubation can be prolonged, and infectiousness cannot be reliably judged by appearance alone. Vaccination records, species, exposure history, animal-control rules and veterinary assessment all shape what happens next. For owners, the safest practical rule is simple: keep rabies vaccines current, supervise pets outdoors when possible, and report direct contact with potentially rabid wildlife rather than waiting for symptoms.
What people should take from the alert
The CDC alert lands in an awkward space between reassurance and urgency. The United States is not reporting human rabies on the scale of common respiratory or foodborne illnesses. Most people will never need rabies PEP. Most bats do not have rabies. Most encounters with wildlife do not lead to transmission.
Yet a small number of cases are enough to justify an unusually disciplined response because rabies is so unforgiving after symptoms begin. That is why public-health advice can sound strict: do not wait for symptoms, do not assume a tiny bat bite would be obvious, do not decide on your own that a wild animal seemed healthy, and do not improvise the treatment schedule if PEP has been started.
At the same time, health departments do not want every wildlife sighting to become an emergency-room visit. Their job is to sort true exposure from proximity, to use testing and observation when appropriate, and to preserve treatment for the people who actually need it. This summer's events exposed how much expertise sits behind that seemingly simple decision.
For the public, the safest workflow is straightforward. After a bite, scratch or possible contact with saliva from a suspect animal, wash the area immediately with soap and water and contact a health professional or health department promptly. Give them specifics: the animal species, where the encounter happened, what kind of contact occurred, whether the animal is available, whether a pet was involved, and whether you have ever received rabies vaccine before. Those details are not bureaucracy. They are the evidence used to decide what protection is necessary.
Rabies exposure: quick answers
Does a rise in PEP use mean more Americans have rabies?
No. PEP is preventive treatment given after a possible exposure and before disease develops. CDC's advisory documents increased inquiries, treatment use and administration errors; it does not say those increases equal a comparable rise in confirmed human rabies cases.
What should I do immediately after a possible bite or scratch?
Wash the area thoroughly with soap and water and contact a clinician or public-health authority promptly. CDC's public guidance recommends about 15 minutes of washing after a possible rabies exposure.
Should I start rabies shots every time I see a bat indoors?
Not automatically. A health official should assess whether contact may have occurred and whether the bat can be safely captured and tested. The correct recommendation depends on the details of the encounter.
Can a delayed vaccine dose mean starting the whole series again?
Usually not for a short delay. CDC says deviations of a few days generally are not a concern, while longer deviations require consultation. Clinicians can use the CDC PEP calculator to evaluate the schedule.
Is there currently a national shortage of rabies vaccine?
CDC said there was no shortage of human rabies vaccine or human rabies immune globulin when it issued the September 10 advisory, though health departments were advised to monitor supplies.
