Fourteen percent of practices (n = 132) posted advice on the use of insect repellent during the August data collection period, a decrease of 1% from the January data collection period (Table 4) . A decrease in the proportion of practices posting travel advisories was also seen; 21% (n = 189) posted information about travel advisories in January compared with only 14% (n = 130) in August. While the other content themes were not assessed during the January period, 14%, 11%, and 9% had information posted in August on sexual transmission of Zika virus, prenatal testing for Zika virus, and draining of standing water to reduce mosquito populations, respectively. In addition, only 5% of practices offered Zika virus information in Spanish during the August data collection period. Compared with OB/GYN-only practices, practices affiliated with hospital systems were significantly more likely to post Zika virus information in any location during both the January and August data collection periods: university-affiliated hospital system-January: odds ratio (OR) (95% confidence interval [95% CI]) = 5.7 (3.50-9.20), August: OR (95% CI) = 8.4 (5.31-13.17); non-university-affiliated hospital system-January: OR (95% CI) = 2.7 (1.88-3.92), August: OR (95% CI) = 6.8 (4.75-9.60) ( Table 5 ). There was no significant association between posting and multispecialty practices during either data collection period.
