A lesser-known tick-borne disease is drawing increased attention in the United States as warmer weather helps ticks spread more widely. Health experts are warning that some of these infections can pose risks similar to Lyme disease, even though many people may not recognize the threat.
One major concern is that this illness may not produce the warning rash many people associate with tick bites and Lyme disease. Without that early sign, infections may be harder to identify quickly, which can delay diagnosis and treatment and make public awareness more difficult.
Doctors are also watching the broader rise of new and unfamiliar tick-borne diseases as tick populations expand. The concern is not limited to one illness, with researchers and clinicians increasingly focused on virus families that may already be finding ways to avoid the body’s immune defenses.
The spread of these diseases highlights how fast the tick-borne health landscape is changing in the U.S. As summer advances, experts are urging greater attention to tick exposure and to symptoms that may not match the most familiar signs of Lyme disease.
