SANTA CRUZ, Calif., Dec. 20 (UPI) -- Scientists say a tree disease killing large swaths of California's coastal forests may be linked to an increase of human cases of tick-borne Lyme disease.
Changes in the forest cover affect many species of animals, a number of which serve as hosts for the ticks that can bite humans and transmit the disease, which causes painful joint swelling, fatigue and even neurological damage, the Santa Cruz (Calif.) Sentinel reported Monday.
