As spring settles across the Northern Hemisphere, public health officials are raising renewed awareness about the growing risk of tick bites and the diseases they can transmit. According to the latest data from the U.S. Centers for Disease Control and Prevention (CDC), emergency room visits for tick bites are currently higher than usual in many parts of the country, marking the highest rates for this time of year since 2017 in all regions except the South Central United States.
The CDC’s Tick Bite Tracker, released in a statement on April 23, 2026, shows that increased outdoor activity during warmer months is leading to more frequent encounters with ticks, which can carry pathogens responsible for Lyme disease, Rocky Mountain spotted fever, and alpha-gal syndrome. While the data reflects U.S. Trends, the underlying risks are relevant globally, particularly in temperate regions where tick populations thrive during spring and early summer.
Alison Hinckley, PhD, an epidemiologist and Lyme disease expert with the CDC’s Division of Vector-Borne Diseases, emphasized that prevention remains the most effective strategy. “Tick season is here and these tiny biters can make you seriously sick,” she stated. “The good news is you have options to help prevent tick bites when you spend time outdoors: You can wear EPA-registered insect repellent and permethrin-treated clothing, do tick checks, and remove attached ticks as quickly as possible.”
She added that removing an attached tick within 24 hours can significantly reduce the risk of Lyme disease transmission, underscoring the importance of prompt action rather than waiting to seek emergency care unless symptoms develop.
Each year, an estimated 31 million people in the United States experience a tick bite, with Lyme disease being the most commonly reported tickborne illness. The CDC estimates approximately 476,000 Americans are diagnosed and treated for Lyme disease annually, though not all cases are reported through official surveillance systems.
Public health agencies continue to recommend layered protection strategies for individuals spending time in wooded, brushy, or grassy environments. These include using Environmental Protection Agency (EPA)-registered repellents containing DEET, picaridin, IR3535, or oil of lemon eucalyptus on exposed skin, and treating clothing and gear with products containing 0.5% permethrin.
Performing full-body tick checks after returning indoors—particularly under the arms, in and around the ears, inside the belly button, behind the knees, between the legs, around the waist, and in the hair—can help detect ticks before they attach or shortly afterward. Showering within two hours of coming indoors has also been shown to reduce the risk of tickborne disease by washing off unattached ticks and providing an opportunity for inspection.
If a tick is found attached to the skin, health authorities advise using fine-tipped tweezers to grasp it as close to the skin’s surface as possible and pulling upward with steady, even pressure. Twisting or jerking should be avoided, as this can cause mouthparts to break off and remain in the skin. After removal, the bite area and hands should be cleaned thoroughly with rubbing alcohol, an iodine scrub, or soap and water.
The CDC does not recommend sending ticks to commercial laboratories for testing, as results may not reliably indicate whether a person has been infected. Instead, individuals are encouraged to monitor for symptoms such as fever, chills, fatigue, headache, muscle and joint aches, and swollen lymph nodes in the days and weeks following a bite. The appearance of an erythema migrans (EM) rash—often described as a “bull’s-eye” lesion—though not present in all cases, warrants prompt medical evaluation.
In addition to Lyme disease, ticks in various regions can transmit other pathogens causing illnesses such as anaplasmosis, babesiosis, Ehrlichiosis, Powassan virus disease, and, in rare cases, alpha-gal syndrome—a condition linked to red meat allergy following a bite from the lone star tick (Amblyomma americanum).
Internationally, similar concerns exist in Europe and parts of Asia, where Ixodes ricinus and Ixodes persulcatus ticks are primary vectors for Lyme borreliosis and tick-borne encephalitis (TBE). While the U.S. Data highlighted in the CDC release does not reflect global incidence, the preventive measures—repellent use, protective clothing, tick checks, and prompt removal—are widely endorsed by health organizations including the World Health Organization (WHO) and the European Centre for Disease Prevention and Control (ECDC).
As Lyme Disease Awareness Month approaches in May, health departments nationwide are distributing educational materials and encouraging communities to adopt preventive habits. The CDC’s Tick Bite Tracker remains updated weekly and is accessible online, offering near real-time insights into regional trends that can help individuals gauge local risk levels.
For those seeking authoritative guidance, the CDC provides comprehensive resources on tick prevention, symptom recognition, and when to seek medical care through its official website. State and local health departments also offer region-specific information, including details on prevalent tick species and associated diseases.
With outdoor recreation on the rise and climate patterns influencing tick habitats and activity periods, staying informed and vigilant remains key to reducing the burden of tickborne illness. Simple, consistent precautions can go a long way in protecting individuals and families during peak tick season.
