SAN FRANCISCO (CBS/AP) — San Francisco Bay Area’s trails and open space hold a higher risk of tick-borne disease than previously thought.
Scientists collected 622 ticks from 20 sites in recreational areas from Sonoma County in the north to Santa Cruz County in the south and found a higher percentage of young ticks were infected with bacteria that produces Lyme disease-like symptoms, according to a new study by Stanford University researchers.READ MORE: Volunteers Spread Out Across Bay Area for Annual Coastal Cleanup

Lyme disease can be difficult to diagnose. Early symptoms include fever, headache, fatigue and sometimes a rash that looks like a bull’s-eye centered on the tick bite. If left untreated, the infection can cause arthritis, joint pain, immune deficiencies and a persistent cognitive fog, the study says.MORE NEWS: San Francisco Schools, Public Health Dept.
