This troubling rise is focused primarily in the Northeast of the country, where June statistics reveal 229 tick bites per 100,000 emergency department visits, a substantial increase from 167 per 100,000 recorded in June 2024.
Tick bites not only cause local discomfort but can lead to serious illnesses. One of the most common is Lyme disease, caused by the bacteria Borrelia, but it’s not the only one.
Blacklegged ticks, also known as deer ticks, are responsible for transmitting diseases such as babesiosis, anaplasmosis, and the Powassan virus, all potentially dangerous to human health.
What is behind this rise?
Experts attribute this uptick in cases to a combination of environmental and climate factors. Dr. Dennis Bente, professor of microbiology and immunology at the University of Texas School of Medicine, told CBS News that the tick population is at record levels in several states.
“We’re seeing a longer tick season nationwide, something that used to be a relatively predictable seasonal threat,” he said.
The extension of these parasites’ activity throughout the year is largely due to global warming. Warmer winters and wetter springs are creating favorable conditions for their reproduction and geographic spread.
“We’re seeing ticks move into areas where they weren’t present before,” warned Dr. Céline Gounder, CBS News medical contributor and chief health correspondent at KFF Health News.
This scenario poses a serious public health challenge. “Most people don’t know that ticks transmit more viruses and diseases than any other animal in the world,” said Bente, who describes these creatures as “sly opportunists” that lie in wait in brush and tall grass until a person or pet passes nearby.
How you can protect yourself
In light of this outlook, experts recommend fundamental protective measures: wear long-sleeved clothing and use insect repellent during outdoor activities, perform thorough body checks when returning home, and shower to remove any ticks before they attach.
They also suggest using mirrors to inspect hard-to-reach areas such as the groin, the scalp, the underarms, behind the ears, and behind the knees.
Personal vigilance and education about these risks become essential in an era when ticks are no longer a seasonal threat, but a persistent concern.
