Round 1

Reviewer 1 Report

Begum et al., have presented an interesting outcome of social media involvement in chikungunya disease outcome. It would be interesting to have data from any other outbreak to show the significance. In my opinion, this is not enough data to publish in this journal.

Reviewer 2 Report

The paper highlights the importance of "media" towards the reduction of chikungunya cases in Bangladesh. Although the paper is very interesting, there are certain concerns about the reporting and conclusions. As seen in Figure 2, the temporal pattern of cases is nearly the same as the number of engagement/articles in media. This means as the number of cases increases then there is a high presence of this topic in the media. This goes to show that the media only reacts when the government reports a high number of chikungunya cases. If the intention was to show media having an impact on cases, then the correlation should be inverse. This means if there is a high presence of media regarding chikungunya, then cases should be low, however when the media presence of chikungunya is low, then cases would continue to rise. Therefore, the highly correlated pattern seen between the two variables could be due to the reaction of the media due to the high cases reported by the government. 

The statistical analysis applied in this does not appropriately answer the main hypothesis of the study if whether media has an effect on the prevention and control of chikungunya. I suggest re-evaluating the entire analytical part to really capture whether the media has an impactful role in the reduction of chikungunya cases over time. 

It would be interesting also in the future that the authors include the content of each media type. For example, does the post/article present how to do prevention and control and to what extent? What are the comments? Does it present any information such as questions about the prevention and control? These pieces of information could reflect the engagement of users on their attitude towards prevention and control of chikungunya. Although the likes and shares can potentially reflect community awareness, it would be best to do a qualitative analysis of the comments or even the statuses made by people towards Chikungunya. 

 

Minor Comments:

  1. There is no caption in Figure 1 and 2. Also, the images provided have very low resolution. I advise the authors to reupload a better image.
  2. For Figure 2, I suggest separating each category (e.g. cases vs news, cases comments, cases likes/reaction) to see the temporal trend line. The point of this figure is to really show how media could influence the trend of cases too.

Round 2

Reviewer 1 Report

The authors have significantly improved the manuscript.

Reviewer 2 Report

The authors did clarify both in their response and the revised manuscript about my concerns. 

The images of the Figures are still in low resolution. I suggest for them to upload a better one.
