WASHINGTON \u2014 The prime time for ticks is here in the United States, and after an especially active start to the season, experts are urging the public to stay alert and take preventive measures. <\/p>\n
Monthly emergency department visits for tick bites in April spiked to their highest level since 2017 and continued to remain high throughout May and June, according to the Centers for Disease Control and Prevention\u2019s tick bite tracker.<\/p>\n
Though it\u2019s hard to predict what the rest of the season will look like, given that tick activity depends on a number of different factors, there has definitely been a recent geographic expansion of the area ticks inhabit, said Pilar Fernandez, a disease ecologist and assistant professor at Washington State University. <\/p>\n
The tiny blood-suckers, which tend to thrive in warmer climates, are spreading to places that used to be too cold for their existence, she said during a July 1 SciLine media briefing, as temperatures rise in the United States and around the world.<\/p>\n
With more ticks comes a greater risk of individuals developing tick-borne diseases such as Lyme disease, Alpha-gal syndrome and anaplasmosis. That\u2019s why researchers are encouraging people to know their facts and learn how to protect themselves from bites as they venture outdoors. <\/p>\n
What\u2019s going on this year?<\/p>\n
According to the CDC, an estimated 31 million people are bitten by ticks each year, with most encounters taking place between April and October. But in 2026, ER visits began rising as early as March. <\/p>\n
Weekly ER trips for tick bites are also up in every U.S. region except for South Central as of June 28, the online tick tracker shows. <\/p>\n
Global warming is certainly one reason behind this recent surge in tick activity, though Fernandez said the whole picture is much more complicated.<\/p>\n
Because ticks can live for up to two to three years, it\u2019s difficult to understand the delayed seasonal effects of increased temperatures or precipitation on their population, she said.<\/p>\n
Other factors including local environmental conditions and how much time people spend outside can have an impact on annual tick encounters, she added. <\/p>\n
Every spring and summer, she said, people ask her if it\u2019s going to be a \u201cbig year\u201d for ticks, which is \u201ca really hard question to answer, because it\u2019s not equal across all locations.\u201d <\/p>\n
Most tick cases are recorded in the Northeast and Midwest, but different species of ticks are found in every region of the country. And as the population expands into areas where people are unaware of how to protect themselves and unaccustomed to checking for bites, the threat of contracting a tick-borne infection grows, Fernandez said. <\/p>\n
Tick-borne diseases<\/p>\n
Ticks carry pathogens that they then pass on to humans by biting into their skin and feeding on their blood. An untreated tick bite can lead to the development of one of nearly 20 different human diseases in the U.S., the most common of which is Lyme disease \u2014 about 476,000 patients are treated annually, according to the CDC. <\/p>\n
Another tick-borne infection that has been on the rise is Alpha-gal syndrome, which causes people to experience a serious allergic reaction after they eat red meat or other animal products that contain the sugar molecule alpha-gal. It is most commonly associated with the lone star species of tick distributed throughout the Northeastern, Southern and Midwestern United States. <\/p>\n
Initial symptoms of tick-borne illnesses are unspecific and often the same as those that come with regular sickness, such as a fever, headache, muscle aches and joint pain, according to Alvaro Toledo, an associate professor in the Department of Entomology at Rutgers who also spoke at the July 1 media briefing. <\/p>\n
\u201cPhysicians need to be vigilant and aware if they receive a patient with symptoms that are compatible with a tick-borne disease,\u201d he said.<\/p>\n
What if you find a tick?<\/p>\n
If one discovers a tick on the skin, Toledo said the proper response is to first quickly remove the tick with tweezers by pinching and pulling it up in a vertical motion, then disinfecting the area and monitoring for signs of sickness. <\/p>\n
People should not, on the other hand, deal with a tick by burning it off or applying petroleum jelly to the bite, said University of Wisconsin-Madison Assistant Professor Adela Oliva Chavez, a tick researcher, at the briefing. <\/p>\n
\u201cThose are myths,\u201d she warned. <\/p>\n
Ticks typically do not transmit infection until after they have been attached to the skin for 24 hours, which is why the CDC recommends people aim to remove the pests as soon as possible within the first day. <\/p>\n
However, experts say the most effective way to prevent tickborne disease in humans is by limiting exposure to ticks in the first place. <\/p>\n
Toledo said people should use chemical sprays such as permethrin on their clothing and classic bug repellents on their skin to keep ticks away. It\u2019s also a good idea to wear long, light-colored clothing when spending time in forests and other highly vegetated areas where ticks are abundant. <\/p>\n
But, he added as a reminder to the public, there is \u201cno zero-risk zone anywhere when you go out \u2026 even in your backyard, risk is not zero.\u201d <\/p>\n
Individuals can further reduce their chance of acquiring a tick bite by checking their pets just as often themselves, according to Oliva Chavez. Dogs and cats can easily bring ticks into the house from outside, and if they aren\u2019t yet attached to the animal\u2019s flesh, they can make their way onto humans, she said.<\/p>\n
