The United States is experiencing an increase in tick-related illnesses, prompting health alerts, particularly in eastern parks. New Jersey officials have identified five specific zones with elevated tick populations and associated risk. Cases of a rare disease transmitted by ticks have been reported in California, adding to national concerns. The increase in consultations suggests a wider spread of tick-borne infections across the country. Parks in New Jersey provide ideal habitats for several tick species, increasing the likelihood of human exposure. Authorities are advising the public on preventative measures to avoid tick bites and reduce the risk of contracting these illnesses.
