Lyme disease is a disease due to bacteria In the US, deer ticks, aka black-legged ticks, are transmitted to humans through the bites of certain species of ticks (Ixodes scapularis or Ixodes pacificus). And while it has been under-diagnosed or misunderstood by the medical community, experts are warning the insects are a growing problem across America.

Traditionally, Lyme disease was regarded as a problem in the wild Northeast region of the Americas. Last year, however, reports began to show that Lyme disease is a growing problem In most parts of the country, including California and even urban areas.

An emergency medicine physician at Stanford Health Care and a medical specialist in the wild, Dr. James Marvel has researched the factors contributing to the spread of Lyme disease in the US. In an interview with CNET, he said that data over the past few decades shows that Lyme disease has “bloomed” in several US states and counties, especially in the Northeast.

“There is some suspicion that climate variables are contributing to this, especially in the context of global warming,” so the environment may be more conducive to ticks, Marvel said. However, ticks have a life cycle of two years, he said, which makes it difficult to track.

“It’s not as simple as saying, ‘A hot day means there are going to be more ticks,'” he explained.

Other factors, such as wood, people expanding construction in tick-filled environments, may also contribute to the increase in the incidence of Lyme disease, Marvel said. Dr. Andres Brann, an infectious disease specialist at the University of Missouri Health Care, said in a 2021 CNET interview that the pandemic has moved more people outdoors and involved them in activities that would expose them to tick bites, such as that hiking.

“You’re seeing a shift toward going outside to be socially distant,” Bran said.

The problem with this, Marvel said, is that it can take some time for antibodies to show up in a blood test — which may also contribute to fewer cases of Lyme disease.
