RENO, Nev. (KOLO) – In Nevada the rate of babies being born with syphilis is among the nation’s highest. According to health officials, congenital syphilis has increased by 1,567% since 2014. Mavel Gutierrez, a Pediatric Infectious Disease Specialist at Renown, says syphilis can be sneaky as 50% of infections go unnoticed, so women may not think to get tested. If they do, many only get tested once.
