[Asia Economy reporters Seunggon Han and intern Juhyung Lim] Controversy has erupted over the epidemiological investigation system established to curb the spread of the novel coronavirus disease (COVID-19) in South Korea. Concerns are growing that epidemiological investigations, which track infection routes through location information and credit card usage records, could lead to privacy violations such as outing (the forced revelation of someone’s homosexuality).

Some countries have introduced app-based systems using Bluetooth signals to prevent such issues, but these systems carry the risk of being less effective due to their voluntary nature.

Experts suggest a flexible approach balancing information disclosure and privacy protection is necessary to avoid stigmatization of certain confirmed cases, which could create gaps in the quarantine network.

In South Korea, epidemiological investigations have identified confirmed patients’ movement paths by securing personal information such as mobile phone location data (GPS) and credit card usage history. When the Minister of Health and Welfare requests a confirmed patient’s mobile phone location information from the police, the police obtain the location data from telecommunications providers and deliver it. This process allows movement paths to be identified within 10 to 15 minutes.

According to the Infectious Disease Control and Prevention Act, the Minister of Health and Welfare and the Director of the Korea Disease Control and Prevention Agency may request personal information of patients or suspects from the police when necessary to prevent or block infectious diseases.

The problem lies in the fact that overly detailed disclosure of movement paths can actually hinder epidemiological investigations.

On the morning of the 11th, the screening clinic at Soonchunhyang University Hospital in Yongsan-gu, Seoul, was crowded with citizens waiting for tests. Due to the COVID-19 cluster infection that occurred at an Itaewon club, the number of confirmed cases in the country increased by 35 on that day. / Photo by Yonhap News

Earlier on the 6th, controversy over outing arose when it was revealed through movement path disclosure that the 66th confirmed patient in Yongin, Gyeonggi Province, had visited several clubs located in Itaewon, Seoul. The clubs visited by this patient are known to be entertainment venues frequently used by sexual minorities.

Some have expressed concerns that sexual minority confirmed patients, fearing negative social stigma and criticism, might avoid self-reporting and evade the quarantine network.

According to Seoul city on the 11th, among 5,517 contacts related to the Itaewon clubs, only about 44%, or 2,405 people, have been reached by health authorities. The rest either provided false information on entry lists or have not responded to authorities’ contact attempts.

In some European countries and the United States, Bluetooth signal tracking apps are being tested as movement tracking systems to prevent such privacy invasion issues.

The Bluetooth app is based on Singapore’s 'Trace Together' app, which was released in March on the open-source sharing platform GitHub by Singapore’s health authorities, and was jointly developed by the American companies Apple and Google.

When a user records their confirmed status in the app and activates it, smartphones with the app installed recognize each other’s Bluetooth signals and share information. If a confirmed patient’s smartphone is nearby, other smartphones in the vicinity alert their owners with a warning sound to encourage voluntary social distancing.

This method reduces privacy concerns by not directly exposing the confirmed patient’s personal information, but it relies heavily on voluntary participation from the public. Effective social distancing requires as many people as possible to use the app.

In Singapore, where the app was first implemented, only about 20% of the population downloaded the Trace Together app. As a result, gaps in the quarantine network led to a large-scale secondary infection centered on migrant workers, forcing the Singaporean government to implement a national lockdown.

Experts advise that an epidemiological investigation system balancing transparent information disclosure and individual privacy protection is necessary.

Lee Dong-hoon, former chairman of the Korean Medical Association’s Influenza Countermeasures Committee, appeared on 'YTN News Night' on the 8th and explained, “When confirmed cases occur in entertainment facilities, it is difficult to identify infected individuals. Especially, some people find it hard or are reluctant to voluntarily disclose that they visited such venues, and they may hide due to fear of disadvantages.”

He added, “If information such as sexual orientation is mentioned in the media, it can lead to specific sexual prejudices and stigmatization. This may cause people to avoid actively participating in epidemiological investigations and go into hiding, which can disrupt quarantine efforts.”

He further stated, “In cases where many confirmed patients occur or the issue is socially sensitive, it might be helpful to handle some confirmed cases confidentially while obtaining cooperation for comprehensive investigations.”
