Sperm donated in Florida is at risk of infection from the Zika virus.
According to the CDC, sperm donated in three counties since June 15, 2016 may have been affected by a strain.
Miami-Dade, Palm Beach and Broward are home to 12 different sperm banks.
Officials warned the public that just because the sperm is stored or frozen does not mean that it kills off the virus. People are still at serious risk.
An estimated 80 percent of people who contract Zika do not know that they have it due to a lack of symptoms, so it can spread extremely easily.
There is no available test to screen semen for Zika, and it cause brain abnormalities, eye defects and hearing loss in babies.
