Further, the report found that disease cases from infected mosquitoes, ticks and fleas have tripled in 13 years and since 2004, nine vector-borne diseases were discovered or introduced for the first time from the United States and its territories.
According to the CDC report, 48,000 tick-borne diseases were reported in 2016 and Lyme disease accounted for 82 percent of all tick-borne diseases between 2004 and 2016. In 2004, 22,000 tick-borne diseases were reported. In its report, the CDC said the nation needs to be better prepared to face this public health threat.
“Zika, West Nile, Lyme, and chikungunya—a growing list of diseases caused by the bite of an infected mosquito, tick, or flea—have confronted the U.S. in recent years, making a lot of people sick. And we don’t know what will threaten Americans next,” CDC Director Robert R. Redfield said in a news release. “Our Nation’s first lines of defense are state and local health departments and vector control organizations, and we must continue to enhance our investment in their ability to fight against these diseases.”
