  • The general elections for the 21st National Assembly in the Republic of Korea were scheduled for April 15th, 2020, which was during the novel coronavirus disease (COVID-19) outbreak. To ensure a safe election, the Korean Centers for Disease Control and Prevention (KCDC) recommended several public health measures. The KCDC developed key interventions after reviewing the general election strategy that targeted COVID-19 patients and individuals isolating at home. Four voters who participated in the election tested positive, but did not contract COVID-19 during voting. The results demonstrated that the KCDC minimized the spread of infection in the community during the election. The measures implemented by KCDC during the election held under a COVID-19 outbreak cannot be generalized to elections as a whole because cultural and national consciousness vary between countries. Nevertheless, it demonstrates that the systemic strategies and applications against the pandemic can minimize the possibility of viral spread.
Korea borders with China where there has been active passage of materials and personnel between countries. After reports of unexplained pneumonia cases in Wuhan [1], the KCDC assessed the risk and organized a task force. The cases of unexplained pneumonia were monitored, resources such as protective equipment and hospital facilities were managed, and a new quarantine and diagnosis system was introduced. On January 20th, the first COVID-19 case in Korea was reported during a customs inspection [2]. This patient was a Chinese national living in Wuhan. Initially, the cases in Korea emerged due to the influx of foreigners and a few families with the infection. However, on February 18th there was viral transmission at a church in Daegu leading to a large outbreak. Since infection in the community was serious, Korea raised the national crisis alert to the most severe level and strengthened the response to the pandemic. Due to the large number of patients, temporary isolation facilities called Living Treatment Centers were established, and mild cases of symptomatic and asymptomatic disease were managed. From 1st to 14th April, the average number of patients per day was 56. The average number of overseas immigrants was 5,218.
In Korea, the general elections for the 21st National Assembly were planned for April 15th, 2020. The participation in the election of COVID-19 patients and individuals who were isolating at home was a task to ensure the constitutional right of suffrage, and to achieve the public health goal of preventing the spread of infectious disease in the community. It was important to have an accurate understanding of the voting process, a precise guide for COVID-19 patients and individuals who were isolating at home who wanted to vote, and management guidelines for support personnel. To that end, the Election Commission, the Ministry of Interior and Safety, and the KCDC worked closely together.
Since patients and individuals who were isolating at home had indicated their desire to participate, preparations were made for the election. There was a lot of concern regarding spread of infection in the community because of mass gatherings during the election, which facilitated contact with each other. To ensure a safe election, the KCDC envisaged multiple scenarios and introduced steps to alleviate the risk of infection. In this review, the public health interventions adopted in Korea are presented and a public health plan and related measures for an election during the COVID-19 outbreak are discussed.
1. The Korean election and vote
The types of voting for the National Assembly elections in Korea include resident voting, overseas voting, early voting, and general voting. The prevention of infection is described in this article for resident voting, early voting, and general voting. Voting at the place of residence was previously registered. Early voting was held on April 10th and 11th, and was reported in 3,500 polling stations nationally. On April 15th, the general election was held. There were 29,126,396 Koreans (constituting 66.2% of all voters), who cast their ballot. Patients with COVID-19 were allowed to vote from their place of residence by mail. Patients and individuals who were isolating at home were required to vote early. There were 446 voters at the Living Treatment Centers who were registered to vote from their place of residence. Amongst individuals who were isolating at home, 13,789 (23.2%) voters were registered to vote in the election. In this election, 525,000 participated as election staff, assistants, and election observers.
2. The risk of COVID-19 during the election
The experiences during the past elections including the expected number of voters, polling stations, and individuals isolating at home on election day were reviewed. Based on this analysis, a review meeting was held, and discussions with the relevant government departments were conducted. It was concluded that the infection could be managed adequately by regulating the environment at the polling stations with good ventilation [3], and encouraging the management, staff, and voters to wear personal protective equipment (PPE).
Public measures during the election consisted of planning, practice, and assessment (Table 1). The KCDC personnel coordinated with the government departments related to the election such as the Ministry of the Interior and Safety, local governments, and the National Election Commission. The electoral guidelines for individuals isolating at home were established and distributed via continuous meetings (offline and online) to address the public health concerns during the election.
3. The election step
Since the general elections for the 21st National Assembly were held during the COVID-19 pandemic, separate polling booths were set up to regulate the flow of voters to ensure a safe election. The voters who had a fever and/or respiratory symptoms voted at isolated polling booths and asymptomatic voters cast their vote at the regular polling booth. Before the vote was cast, the voters’ temperature was measured and checks for respiratory symptoms were performed. The asymptomatic voters used a hand sanitizer before putting on disposable gloves and maintained 1-meter distance from each other. They carried an ID card for verification checks by the election staff and submitted their digital signature to receive a ballot paper. They went behind the voting screen and posted the ballot paper in the box. Before leaving, they removed their disposable gloves and sanitized their hands again.
The voters who had fever and/or respiratory symptoms were guided to an isolated polling booth and the election staff handed them a ballot. After casting their vote, they placed the ballot in the envelope, sealed it, and handed it to the election staff at the isolated voting booths, who then delivered it to the election staff to post it into the box. The election observers accompanied the election staff at the isolated booth throughout the election and witnessed the whole electoral process. After the voters left, the election staff disinfected the surface environment, and equipment used in the election.
The KCDC established guidelines for COVID-19 patients and individuals isolating at home during the general elections for the 21st National Assembly (Table 2). The patients were registered to vote in their place of residence for 5 days from March 24th. The ballot paper and return envelope for the voters were received via the mail. The patients who were diagnosed after the registration period cast their ballot during an early voting period between April 10th and 11th. The National Election Commission installed and managed the early voting stations specifically set up at the Living Treatment Centers. The election step was the same as usual and the election managers in the Living Treatment Centers used PPE.
Each of the local government officials generated a list of names via a mobile application and texting for the individuals isolating at home who wanted to vote. The public authorities checked the temperature and the respiratory symptoms of the cases isolating at home on April 15th. They were only allowed to leave the home when they had no symptoms. The public officials checked their route from time to time and managed their use of the app. Individuals isolating at home, who were allowed to go out to vote, were required to wear a mask, and either use their own vehicle or walk alone. They could only vote after 6 pm following the general vote. Cases of COVID-19, if confirmed after the vote between April 10th and 29th, were contacted and monitored.
4. Confirmed COVID-19 case
As of April 15th, 2020, the total number of cases isolating at home was 59,387. Among those individuals, 13,789 were registered to vote in the election as of April 14th, and 11,511 (83.5%) individuals participated in the election on April 15th. Among the COVID-19 patients who were confirmed after the Election Day, 4 participated in the vote, and they were all males (1 in his 40s, 2 in their 50s, and 1 in his 60s). Two cases were from the Gyeonggi and Gyeongbuk provinces, respectively. Three of the 4 patients were infected due to close contact with a confirmed case, and 1 was an imported case from the Arab Emirates. At the time of the vote, these patients declared that they exhibited no symptoms, and they had either walked or drove their car to the polling station. It was determined that these patients had spent less than 10 minutes at the polling station. All of these patients adhered to the rules of wearing a mask and maintained physical distance. Hence, no potential risk of spreading the virus was determined during the voting process (Table 3).
Korea is not the first country to hold an election during a pandemic. In the United States in 1918, elections were held during the influenza pandemic [4]. During the elections, preventive measures such as wearing a mask and maintaining adequate distance were taken at polling stations in San Francisco. When influenza was prevalent in San Francisco during October 1918, official orders were issued for mandatory wearing of masks when in public or in groups of 2 or more people. In addition, all employees and voters at polling stations were required to wear masks on Election Day. In Idaho, all voters were mandated to stand in a single line at the polling station to prevent disorderly crowds that may spread the disease [4]. In this election, in Korea, all voters were required to wear masks, and keep a distance of more than 1 meter. The voters used disposable gloves after engaging in hand hygiene at the entrance to the polling station.
The turnout rate in the 1918 elections in the United States was lower than in previous elections. There were many reasons for such low turnout in the elections, such as the ongoing war, but the main factor for the low turnout was the influenza pandemic. Many voters chose to stay at home because they were already ill due to the disease or feared becoming infected during the voting process [4].
One remarkable distinction between the elections of the 2 countries was that the voter turnout rate in Korean election was 66.2%, which was higher than in previous elections. Further investigation underlying the findings is needed, but it appears that the isolated polling booths reduced voters’ anxiety about disease transmission. Furthermore, special measures adopted to facilitate voting by patients and individuals isolating at home also reduced anxiety levels.
Furthermore, resident voting measures guaranteed suffrage to qualifying citizens to vote from their place of residence. Temporary polling stations were set up at the Living Treatment Centers to allow patients to participate in early voting. Voters isolating at home were granted a separate voting time to encourage their participation in the election. After the election, it was determined that 4 individuals who had participated in the voting were confirmed as COVID-19 patients. However, these individuals had not contracted COVID-19 during the voting process of the election. There were no other confirmed cases of infection among voters and the election management team. Hence, such results suggest that the overall process and preventive measures taken during the election process minimized the spread of infection.
In 2015, the Korean government was criticized for its weak measures for the prevention, cooperation, and control of the MERS epidemic. The lesson of Korea’s preventive measures during the COVID-19 epidemic is attributed to a systematic operational plan and implementing various strategies through cooperation between related ministries and agencies.
Due to differences in other nations' election processes, confirmed cases, culture, public awareness, and response capabilities, the public health measures adopted by Korea in this election cannot be generalized and applied to other countries. However, it can be concluded that well-established strategies and applications may reduce the risk of contagion.
