Objective: The purpose of this study was to describe source, length, number of views and content of the most widely viewed Zika Virus (ZIKV)-related YouTube videos. We hypothesized that ZIKV-related videos uploaded by different sources contain different content.
The 100 most viewed English ZIKV-related videos were manually coded and analyzed statistically.
Among the 100 videos, there were 43 consumer-generated videos, 38 internet-based news videos, 15 TV-based news videos and 4 professional videos. Internet news sources captured over two-thirds of the total 8,894,505 views. Compared with consumer-generated videos, internet-based news videos were more likely to mention ZIKV?셲 impact on babies (Odds ratio, 6.25; 95% CI, 1.64, 23.76), the number of cases in Latin America (OR, 5.63; 95% CI, 1.47, 21.52); and ZIKV in Africa (OR, 2.56; 95% CI, 1.04, 6.31). Compared with consumer-generated videos, TV-based news videos were more likely to express anxiety or fear of catching ZIKV (OR, 6.67; 95% CI, 1.36, 32.70); to highlight that the public was afraid of ZIKV (OR, 7.45; 95% CI, 1.20, 46.16); and to discuss avoiding pregnancy (OR, 3.88; 95% CI, 1.13, 13.25).
Public health agencies should establish a larger presence on YouTube to reach more people with evidence-based information about ZIKV.
