If people avoid testing because of cost, cases go undiagnosed
Across Virginia and the broader United States, emergency rooms are receiving more patients for tick-related illnesses than at any point in the past decade — a quiet but accelerating collision between shifting ecological conditions and a healthcare system not fully prepared to absorb the cost. Warmer winters have extended tick seasons and expanded the geographic reach of species that carry Lyme disease, Rocky Mountain spotted fever, and other serious infections. What makes this moment particularly telling is not just the medical burden, but the financial one: patients are being asked to choose between knowing what ails them and affording the answer. In this tension between nature's expansion and human infrastructure, the most vulnerable are left navigating both a biological threat and an economic one.
- Emergency rooms are logging tick-related visits at their highest levels in ten years, signaling that what was once a seasonal nuisance has become a sustained public health pressure.
- Warmer winters and longer tick seasons are pushing tick populations into new regions and keeping them active longer, dramatically increasing the odds of human exposure.
- Patients facing suspected tick-borne illness must weigh the cost of diagnostic testing — sometimes hundreds of dollars out of pocket — against the risk of leaving a potentially serious infection undetected.
- When cost deters testing, cases go undiagnosed and unreported, creating a surveillance gap that prevents public health agencies from understanding the true scale of the outbreak.
- Virginia's emergency departments are among the hardest hit, but the pattern is national, and the strain on hospital capacity is beginning to crowd out resources for other urgent care needs.
- Officials are doubling down on prevention — tick checks, yard maintenance, repellents, permethrin-treated clothing — but acknowledge that as long as tick populations grow, bites and their consequences will follow.
Emergency rooms across the United States are seeing more tick-related illness than at any point in the last decade. Virginia has been particularly affected, but the surge is national in scope, straining hospital capacity and forcing patients to reckon with both a medical threat and a financial one.
Ticks transmit a range of serious pathogens — Lyme disease being the most common, but also Rocky Mountain spotted fever, anaplasmosis, and babesiosis, all capable of causing fever, joint pain, and in severe cases, organ damage. The likely drivers of the current surge include warmer winters that extend tick seasons, a northward expansion of tick habitats as climate patterns shift, and more people spending time outdoors. As tick populations grow, so does the probability of encounter.
The medical crisis is shadowed by an economic one. Diagnostic testing for tick-borne illness can cost hundreds of dollars, and insurance coverage is inconsistent. For patients with high deductibles or no coverage at all, the decision to get tested becomes a financial calculation. When people forgo testing, infections go undiagnosed and untreated — and because unreported cases don't enter public health surveillance systems, agencies lose the ability to accurately map where the problem is worst.
Public health officials continue to emphasize prevention: checking for ticks after outdoor activity, removing them promptly, clearing leaf litter and tall grass from yards, and using repellents or permethrin-treated clothing. The guidance is sound, but prevention has limits. The decade-high emergency room numbers suggest that the healthcare system and its patients are not yet equipped to meet the scale of what tick season has become.
Emergency rooms across the country are seeing more patients with tick-related illnesses than they have in at least a decade. The surge is happening in Virginia and beyond, straining hospital resources and forcing people to confront not just the medical threat of tick bites but the financial burden of getting tested for the diseases they might carry.
Ticks are small parasites that feed on blood, and when they bite, they can transmit pathogens that cause serious illness. Lyme disease is the most common tick-borne infection in the United States, but ticks also spread Rocky Mountain spotted fever, anaplasmosis, babesiosis, and other conditions that can cause fever, joint pain, fatigue, and in severe cases, organ damage. For decades, public health officials have warned about the risk, but the current wave of ER visits suggests the problem is accelerating.
What's driving the surge is not entirely clear from available data, but warmer winters and longer tick seasons are likely factors. Ticks thrive in mild weather and can remain active longer into the fall and earlier into the spring. As climate patterns shift, the geographic range where certain tick species live is expanding northward. People spending more time outdoors—hiking, camping, working in yards—also increases exposure. And as tick populations grow, so does the likelihood of encounters.
But the medical crisis is compounded by a financial one. Patients arriving at emergency rooms with suspected tick-borne illness face a difficult choice: get tested to know what they're dealing with, or skip the test and hope symptoms resolve on their own. The cost of diagnostic testing for tick-borne diseases can be substantial, and many patients are questioning whether they can afford it. Insurance coverage varies, and out-of-pocket expenses can run into hundreds of dollars. For people without insurance or with high deductibles, the decision to seek testing becomes a calculation about money as much as health.
This creates a public health blind spot. If people avoid testing because of cost, cases go undiagnosed and untreated. Tick-borne illnesses can worsen without proper antibiotics. Some infections, if left untreated, can cause long-term complications. And from a surveillance perspective, if cases aren't being reported, public health agencies can't accurately track how widespread the problem is or where it's concentrated.
Virginia has been particularly affected, with emergency departments reporting significant increases in tick-related visits. But the pattern is showing up across multiple states, suggesting this is a national trend, not a regional anomaly. Healthcare systems are beginning to feel the strain. Emergency rooms have limited capacity, and a surge in tick-related cases means fewer resources for other urgent medical needs.
Public health officials are emphasizing prevention. The advice is familiar but worth repeating: check yourself and your family for ticks after spending time outdoors, remove ticks promptly using tweezers, treat your yard to reduce tick habitat by clearing leaf litter and tall grass, and consider using tick repellent on skin and clothing when venturing into wooded or grassy areas. Some people are also using permethrin-treated clothing, which kills ticks on contact.
But prevention only goes so far. As long as tick populations remain high and people spend time in outdoor environments, bites will happen. The question now is whether the healthcare system and public health infrastructure can keep pace with the demand, and whether patients can afford the testing and treatment they need. The decade-high ER visits suggest we're not there yet.

The Hearth Conversation Another angle on the story
Why are tick-related ER visits spiking now, specifically? Is it just that there are more ticks?
Warmer winters and longer seasons are part of it, but it's also that people are outside more, and ticks are moving into new areas as the climate shifts. It's a convergence.
And the testing cost issue—that seems like it could actually make the problem worse, not better.
Exactly. If someone gets bitten and can't afford to find out what disease they might have, they don't get treated. The infection can progress. And public health can't even count the cases.
So the ER visits are just the visible part of a larger problem.
Right. The people showing up at the hospital are the ones sick enough or worried enough to go. How many others are at home, untreated, hoping it goes away?
What does prevention actually look like for most people?
Checking yourself after being outside, removing ticks right away, keeping your yard clear. It's simple in theory. In practice, most people don't do it consistently until they've had a bad experience.
Is there a sense that this is going to keep getting worse?
Unless tick populations stabilize or we get a very cold winter, yes. The conditions that favor ticks are becoming more common, not less.
And hospitals are already stretched thin.
They are. A surge in tick-related cases means something else isn't getting the attention it needs. It's a capacity problem on top of a disease problem.
