Comparison of COVID-19 and MERS Risk Communication in Korea: A Case Study of TV Public Service Advertisements

Purpose

In recent years, the world has been under threat of novel infectious diseases such as Middle East respiratory syndrome (MERS) and coronavirus disease 2019 (COVID-19). Governmental risk communication plays a key role in overcoming the public health crises caused by the emergence of these infectious diseases. The purpose of this study was to identify the focus of Korean public service advertisements (PSAs) in response to the MERS and COVID-19 outbreaks, along with the differences between them.

Methods

A total of five MERS and 17 COVID-19 TV PSAs were analyzed using Lasswell’s Sender, Message, Channel, Receiver, and Effect model and the responses of the Korean government were compared between the MERS and COVID-19 outbreaks.

Results

During the MERS outbreak, the Korean government failed to gain the public’s trust through its PSAs. Despite its best efforts, it provided opaque and selective information on the crisis. Conversely, in the case of COVID-19, the Korean government has successfully worked to strengthen community awareness by supporting and encouraging the public.

Conclusion

Despite the Korean government’s improved communication in the COVID-19 crisis, there has been an insufficient response to the needs of vulnerable groups that could be placed in at-risk situations as a result of domestic violence or mental health problems during outbreaks of novel infectious diseases that require aggressive management.

Middle East respiratory syndrome coronavirus (MERS-CoV) outbreak in South Korea, 2015: epidemiology, characteristics and public health implications

Background

Since the first case of Middle East respiratory syndrome coronavirus (MERS-CoV) in South Korea was reported on 20^th May 2015, there have been 186 confirmed cases, 38 deaths and 16,752 suspected cases. Previously published research on South Korea's MERS outbreak was limited to the early stages, when few data were available. Now that the outbreak has ended, albeit unofficially, a more comprehensive review is appropriate.

Methods

Data were obtained through the MERS portal by the Ministry for Health and Welfare (MOHW) and Korea Centres for Disease Control and Prevention, press releases by MOHW, and reports by the MERS Policy Committee of the Korean Medical Association. Cases were analysed for general characteristics, exposure source, timeline and infection generation. Sex, age and underlying diseases were analysed for the 38 deaths.

Findings

Beginning with the index case that infected 28 others, an in-depth analysis was conducted. The average age was 55 years, which was a little higher than the global average of 50 years. As in most other countries, more men than women were affected. The case fatality rate was 19.9%, which was lower than the global rate of 38.7% and the rate in Saudi Arabia (36.5%). In total, 184 patients were infected nosocomially and there were no community-acquired infections. The main underlying diseases were respiratory diseases, cancer and hypertension. The main contributors to the outbreak were late diagnosis, quarantine failure of ‘super spreaders’, familial care-giving and visiting, non-disclosure by patients, poor communication by the South Korean Government, inadequate hospital infection management, and ‘doctor shopping’. The outbreak was entirely nosocomial, and was largely attributable to infection management and policy failures, rather than biomedical factors.
