Monkeypox has been spreading in nonendemic countries since May 2022 [1]. The media significantly influences how people react to the spread of emerging and reemerging infectious diseases [2]. Protective motivation theory (PMT) posits that people protect themselves using perceptions from 4 cognitive appraisals: perceived severity, perceived vulnerability, outcome efficaciousness, and self-efficacy [3]. We investigated whether news reports contributed to these 4 PMT components to understand the gaps in people’s health information needs.

To categorize the volume trends in media coverage, we divided the timeframe into three periods: (1) May 19-28, 2022, which corresponds to the initial phase of outbreak reporting in Europe and the United States; (2) June 15-16, 2022, marked as the judgment period; and (3) June 22-29, 2022, which represents the reporting period for the outbreak in Asia.

Table 1 shows the number and percentage of fear and coping appraisals and neutral information occurrences in the articles during each period. During the second period, reports noted that an emergency committee acting as an advisory body for the World Health Organization (WHO) Director-General would convene to discuss whether monkeypox should be declared a Public Health Emergency of International Concern (PHEIC) [6]. During the third period, reports noted outbreaks in countries geographically close to Japan, specifically, South Korea, Singapore, and Taiwan, and that the WHO had decided not to declare a PHEIC. A high percentage of fear appraisals was reported across all periods, while the number of coping appraisals was substantially lower.

Figure 1 shows the number of articles and tweets by media category chronologically. The graph presents a waveform that corresponds roughly to the first period of media coverage but not to the amount of coverage in the second or third period. For example, the topics that appeared initially from May 19 to June 6, 2022 (N=69,621 tweets) were as follows: “about monkeypox as an infectious disease” (n=38,988, 56%), “vaccine” (n=23,671, 34%), “misinformation” (n=3481, 5%), “measures” (n=2785, 4%), and “concern about economic shutdown” (n=696, 1%).

We found significantly fewer coping appraisals than fear appraisals in the articles included in this content analysis. However, according to our content analysis of tweets, 56% of citizens (38903/69621) wanted neutral information regarding basic facts about infectious diseases, treatment, vaccines, and other prevention methods.

One limitation of this study is that only major news media were included in the analysis; we acknowledge that scientific and medical media may have published different content. However, the impact is significant because the public consumes information via the major media targeted in this study and disseminates it on social networking platforms. Therefore, confirming the content of such media is essential.

We recommend that crisis management teams should provide easy-to-understand information enabling the media to disseminate basic information on infectious diseases and messages that lead to coping appraisals.
