(REUTERS) -- The number of Americans sickened each year by bites from infected mosquitoes, ticks or fleas tripled from 2004 through 2016, with infection rates spiking sharply in 2016 as a result of a Zika outbreak, U.S. health officials said on Tuesday.
The U.S. Centers for Disease Control and Prevention said that some 96,075 diseases caused by bites by mosquitoes, ticks and fleas were reported in 2016, up from 27,388 in 2004, in an analysis of data from the CDC’s National Notifiable Diseases Surveillance System.
Infections in 2016 went up 73 percent from 2015, reflecting the emergence of Zika, which is transmitted by mosquitoes and can cause severe birth defects. Zika was the most common disease borne by ticks, mosquitoes and fleas reported in 2016, with 41,680 cases reported, followed by Lyme disease, with 36,429 cases, almost double the number in 2004.
