Babesiosis is a disease caused by microscopic parasites known as Babesia, which infect red blood cells. It is primarily transmitted to humans through the bite of infected ticks, particularly the Ixodes scapularis tick, commonly found in wooded and grassy areas. Symptoms can range from mild to severe and may include fever, chills, sweats, headache, and muscle aches. Diagnosis is typically made through blood tests that identify the presence of the Babesia parasites. Treatment usually involves specific antibiotics and antimalarial medications. Preventive measures include using tick repellents, wearing protective clothing, and checking for ticks after outdoor activities.
