The publication of “Zika-Virus-Related Photo Sharing on Pinterest and Instagram” is very interesting. Fung et al concluded that “Pinterest and Instagram are similar platforms for Zika virus prevention communication.”Reference Fung, Blankenship and Goff 1 In their study, Fung et al tried to search the photo record on Pinterest (San Francisco, CA) and Instagram (Menlo Park, CA). There can be a bias in judgement of the relationship between the photo and Zika virus infection or prevention. It might be concluded that there are many posts in the network on Zika virus infection. Nevertheless, it might not be concluded that the network photo sharing is for Zika virus prevention communication. It can be useful if there is a control for the correctness of the shared information. If there is no control, however, the sharing might be a way of promoting problems in disease control. If there is no control, the photo might mislead the viewer and result in unwanted health behavior.Reference Tiggemann and Zaccardo 2 Thus, is it necessary to have a system that might help to identify correct photos and ignore incorrect data. There are some possible ways for managing this problem, such as
-
∙ creating a team to monitor the Internet for information during a disease outbreak,
-
∙ having a system to verify and guarantee the reliability of the website,
-
∙ and constructing and promoting a central health information website generated by the governmental public health sector.
