CDC Mobile

Traffic to the Website from Mobile Devices

Traffic trends since 2013 show a dramatic growth from visitors using smaller mobile devices, surging past CDC’s “mobile moment” in 2016-2017 when mobile traffic began surpassing desktop traffic. By the end of 2020, visits from mobile devices accounted for nearly 70% of traffic to CDC.gov compared to desktop traffic.
