Ellington SR, Simeone RM, Serrano-Rodriguez RA, et al. - Researchers conducted the study for describing Zika virus prevention behaviors among women aged 18 to 49 years and evaluating whether pregnancy status and healthcare provider counseling increases Zika virus prevention behaviors. A population-based cell phone survey of women aged 18 to 49 years residing in Puerto Rico was performed in July–November 2016. The majority of women reported using screens on open doors/windows (87.7%) and eliminating standing water in/around their homes (92.3%). Other Zika virus prevention behaviors were less prevalent (< 33%). Pregnancy status was not as consistently associated with Zika virus prevention behaviors as receiving healthcare provider counseling. Counseling from healthcare providers is an important strategy for increasing the uptake of Zika virus prevention behaviors among women aged 18–49.
