Cities throughout America are spraying chemicals through their streets in unprecedented action in response to an increase in numerous deadly mosquito-borne illnesses.Massachusetts, New York, Texas, and California are among the states using pesticides to combat the increasingly disease-ridden insects.The decision follows a wave of mosquito-borne illnesses in the United States, including West Nile Virus, which hospitalized White House Covid doctor Anthony Fauci earlier this month, 'Triple E', a brain-swelling disease that has killed two Americans this year, and'sloth fever', a disease transmitted from sloths to mosquitos.
