What Is the Risk of Babesia in Suffolk County, New York?
Babesia is increasingly found in Suffolk County ticks
Residents may be exposed through a single tick bite
Coinfections can complicate diagnosis and treatment
Researchers studying ticks in Suffolk County, New York, found a high prevalence of Babesia microti, the parasite responsible for most cases of human babesiosis in the United States.
These findings raise an important question for residents and visitors alike: what is the risk of Babesia infection in Suffolk County?
Babesia is transmitted primarily through the bite of infected blacklegged ticks. Because the same tick may also carry Lyme disease and other pathogens, exposure can sometimes lead to multiple tick-borne infections.
Understanding the prevalence of Babesia in local tick populations can help clinicians and patients better appreciate the potential risk of babesiosis following a tick bite.
Why Babesia Matters in Suffolk County
Suffolk County has long been recognized as an area with substantial tick exposure. As the prevalence of Babesia microti increases in local tick populations, the likelihood of human exposure may also rise.
Suffolk County remains one of New York’s most important regions for studying tick-borne diseases, including babesiosis and Lyme disease. Findings from this region may help clinicians better understand Babesia risk in other parts of New York where blacklegged ticks are common.
Unlike Lyme disease, Babesia infects red blood cells and may lead to symptoms such as fever, chills, fatigue, sweats, headaches, and anemia. Some individuals remain asymptomatic, while others develop more significant illness.

What the Study Found
The investigators identified a high prevalence of Babesia microti in ticks collected from Suffolk County. The findings suggest that residents and visitors may be exposed to Babesia whenever they are exposed to infected ticks.
Because blacklegged ticks can harbor multiple pathogens, a single tick bite may expose an individual to more than one infection.
This overlap is particularly important because Babesia may occur alongside Lyme disease, Anaplasma, or other tick-borne coinfections.
Why Coinfections Matter
Patients infected with both Lyme disease and Babesia may experience a broader range of symptoms than those infected with Lyme disease alone.
Common symptoms associated with babesiosis include:
- Fever
- Chills
- Fatigue
- Sweats
- Headaches
- Anemia
Night sweats may be particularly important. Learn more about night sweats and Babesia symptoms.
Recognizing possible coinfections can help guide diagnostic evaluation and treatment decisions.
What These Findings Mean for Patients
The presence of Babesia microti in Suffolk County ticks does not mean every tick bite will lead to infection. However, the findings highlight the importance of considering babesiosis when evaluating patients with compatible symptoms following tick exposure.
Clinicians should remain aware that some patients may present with both Lyme disease and Babesia, particularly in highly endemic regions such as Suffolk County.
Frequently Asked Questions
How common is Babesia in Suffolk County?
Studies have identified Babesia microti in ticks collected from Suffolk County, suggesting an ongoing risk of exposure for residents and visitors.
Can the same tick carry Lyme disease and Babesia?
Yes. Blacklegged ticks may carry multiple pathogens, making coinfections possible after a single tick bite.
What symptoms can Babesia cause?
Symptoms may include fever, chills, fatigue, sweats, headaches, and anemia, although presentations vary among patients.
Who is at greatest risk for severe babesiosis?
Older adults, immunocompromised individuals, and patients without a functioning spleen may be at higher risk for severe illness.
Clinical Takeaway
Studies identifying Babesia microti in Suffolk County ticks highlight the potential risk of babesiosis following a tick bite. Because Babesia and Lyme disease may be transmitted together, clinicians should consider coinfections when evaluating patients with persistent symptoms after tick exposure.
Understanding local Babesia risk may help improve recognition, diagnosis, and treatment of tick-borne infections.

Yale U had developed a potential treatment for babesia, but it needs to advance to human trials. Would you know the status of that effort? I called over there, but did not receive a call back.
I have not heard anything
High prevalence of babesia microti in Suffolk County, New York have been primarily reported during spring, summer and fall, when ticks are active.
The prevalence of Babesia Microti was highest in Myodes gapperi at 39%. Babesiosis is an emerging tick-borne zoonotic infectious disease.
