THE FIRST CONFIRMED CASES OF COVID-19 IN INDONESIAN CITIZENS

Coronavirus Disease 2019 or Covid-19 was first identified in Wuhan, Central Hubei province, China. More than 200 cases of coronavirus infection and 3 deaths were reported (Parry, 2020). Majority of patients with pneumonia were caused by variables associated with seafood wholesale market in Wuhan, China (Zhu et al., 2020). There is no effective way to fight the virus, and personal hygiene is one step to avoid the spread of Covid-19 (Lai, Tang, Chau, Fung, & Li, 2020). Common symptoms of Covid-19 include fever, respiratory problems, and lung infiltration (Strzelecki, 2020). World Health Organization (2020) stated that Covid-19 is an outbreak case, which is continually reported in various countries (Huang et al., 2020).

Figure 1 shows that the Indonesian citizens who were infected by Covid-19 came from various countries, including 1 Indonesian in Singapore, 9 in Japan, and 2 in Indonesia. The case detail of each country is described in the following.

Singapore
The Ministry of Health said that an Indonesian citizen with positive Covid-19 in Singapore was infected from his employer. He had no history of traveling outside Singapore (Ministry of Health of the Republic of Indonesia). On 18 February 2020, the Singapore Ministry of Health said that the Indonesian citizen who was declared as the 21 st positive case of Covid-19 in Singapore was from the Yong Thai Hang medical shop cluster on 4 February 2020. Fortunately, he was then declared cured with negative lab result and discharged from the hospital (Ministry of Foreign Affairs of the Republic of Indonesia, 2020).

Japan
There were nine Indonesian citizens with positive Covid-19 in Japan. They were all crews of the Diamond Princess cruises from a total of 78 Indonesian citizens. They were treated in hospitals in the cities of Chiba and Tokyo (Ministry of Foreign Affairs of the Republic of Indonesia, 2020). Those who were closely contacted with them were then being isolated and closely observed. Location of the incident

Indonesia
On 6 March 2020, the Indonesian government announced the first case of Covid-19 in Indonesia. The transmission of the virus was originated from a visit of Japanese citizens who were living in Malaysia to Indonesia. Before being tested positive for Covid-19, the 31-year-old woman was detected dancing with that Japanese citizen at a place in the Paloma club on 14 February 2020. Two days later, this woman experienced a cough and she went to an outpatient treatment at a hospital. But ten days later, the cough had not disappeared and she asked to be treated at the hospital. On 28 February 2020, the Japanese citizen called from Malaysia to tell the women that he was tested positive for Covid-19 and being treated in Malaysia.
This case presentation is to describe how the Indonesian citizens were infected at the first place. However, the outbreak control to reduce transmission needs to be done thoroughly. At-risk populations should receive serious attention so that they remain protected from the spread of Covid-19 (Li et al., 2020). Any efforts related to lockdown policies to stop the transmission should be implemented (Wang, Horby, Hayden, & Gao, 2020), especially in Indonesia as a tropical country with large population and mobility that are potentially to be infected with Covid-19. It is therefore suggested for the government to improve health controls at Indonesian entrances to prevent the spread of the virus, early detection system (Indonesia Public Health Association, 2020), reduce mobility, and ask the community to work together to combat Covid-19.
