1. Introduction
Pandemics have far-reaching impacts on various socioeconomic factors and quality of life. Global poverty, for instance, has increased for the first time in a generation. Survey data show that income losses were particularly pronounced among youth, women, the self-employed, and casual workers with lower levels of formal education. Similarly, businesses, especially smaller and informal ones with limited access to formal credit, experienced severe income losses due to the pandemic [
1]. This situation necessitates ongoing attention not only from the government but also from scientists and healthcare professionals who address each case as it emerges.
Moreover, pandemics have had a detrimental effect on the health-related quality of life of the general population. Several factors, including age, sex, marital status, education, chronic diseases, confinement, and financial constraints, have been identified as influencing the quality of life [
2]. During the first wave of the pandemic, prevalent symptoms such as insomnia, anxiety, and depression were majorly reported in multiple countries, with the addition of studies expressing some incidence of PTSD [
3]. Therefore, it is crucial for the general population to play a role in mitigating the transmission of the virus while protecting themselves. This includes ensuring that the public has a consistent and thorough understanding of the disease, from awareness to preventive practices, to effectively implement preventive measures.
Shifting focus to COVID-19, this respiratory infectious disease manifests pneumonia-like symptoms, including fever, dry cough, and shortness of breath [
4]. Transmission transpires through droplets during coughing or sneezing and via contact transmission from the surfaces of inanimate objects [
5]. Identified in Wuhan, Hubei Province, China in December 2019, Indonesia confirmed two cases on 2 March 2020 [
6]. Escalating to over 40,000 cases within four months, Indonesia has become the third country in Southeast Asia with the highest number of COVID-19 cases. Globally, the total number of cases has surpassed 6 million [
6,
7]. The mortality rate of COVID-19 in Indonesia displayed significant diversity, influenced by factors like varying incidence rates, different levels of pre-existing health conditions, the capacity of the healthcare system to respond to the pandemic, and the socioeconomic makeup of the population. The majority of COVID-19 cases and deaths were concentrated on Java Island, which is more developed and home to 152 million people, making up 56% of Indonesia’s total population [
8]. Recent studies conducted in Jakarta, the capital city of Indonesia, indicated that the virus had a disproportionate impact on older individuals with existing chronic health issues. Additionally, areas within Jakarta that had lower rates of vaccination, higher levels of poverty, and higher population densities experienced more severe effects from the virus [
9]. In response to this surge, the Indonesian government implemented large-scale social restrictions and empowered local authorities to enforce measures to curb further transmission in their regions [
10].
To implement proper prevention practices, one’s knowledge and attitude should be solidified to enact these practices. Several factors influence these practices, including knowledge, attitude, occupation, education level, and place of residence. A study conducted in 30 provinces in China demonstrated exemplary results, with an average accurate response rate of 91.2% for knowledge, 98% for attitude, and 96.8% for practices [
11]. Similarly, studies in both the USA and the UK showed that participants generally had good knowledge of the main modes of disease transmission and common symptoms [
12]. In Indonesia, specifically in the capital city of Jakarta, the results were adequate, with average scores of 83% for knowledge, 70.7% for attitude, and 70.3% for practices [
13].
In Indonesia, efforts to heighten disease awareness among the community involved the use of social media to disseminate information on preventive measures [
14]. These preventive actions aim to disrupt the transmission chain, safeguarding individuals and the community. Measures include mask usage, regular handwashing, social distancing, self-isolation, and temperature screening at public places [
14]. Although large-scale preventive measures, such as the nationwide lockdown, contributed to a shorter duration of lockdown and a lower increase in the case growth rate in the post-lockdown era, it also resulted in harsh restrictions on the economy and people’s lives. The people adopted other preventive measures instead, such as mass mask-wearing, patient/suspected case isolation strategies, physical distancing, and contact tracing [
15,
16].
Despite these efforts, the number of cases persists, and the public’s attitude towards the pandemic does not align with the recommended practices. This study seeks to assess the knowledge, attitude, and practices of the community in Medan City concerning the prevention of COVID-19 transmission.
4. Discussion
During the survey, conducted six weeks after the first reported case in Medan city, COVID-19 was a relatively recent and emerging concern in Indonesia, primarily concentrated in Java, even though the first case in North Sumatra was reported on 18 March 2020, only 16 days apart from the first reported case in Jakarta (2 March 2020) [
4,
14]. By 9 May 2020, only 132 cases had been identified, with 12 deaths among 2.9 million citizens, and the sub-district in Medan City that has the most positive patients is Medan Selayang sub-district, with a total of >20 patients being treated [
14]. This research will compare the relationship between the levels of perception and behavior of the people of North Sumatra Province in preventing the transmission of COVID-19. It aims to provide an overview of the community’s response to the pandemic and ways to address it at the grassroots level.
Our study focused on evaluating the community’s knowledge, attitudes, and practices in one of the first sub-districts to report COVID-19 cases in Medan. The participants, predominantly aged between 30 and 39 years, with a high school education or higher, and mostly in occupations such as housewives and drivers, indicated social media as the primary source for preventive measures and COVID information. A quantitative analysis study based on the Protection Motivation Theory (PMT) showed that perceived risk, e-health literacy, public awareness, and health experts’ participation influence public protective behavior when using social media to share COVID-19-relevant content. This result can offer guidance for advocating health practices and information to the public [
20]. Despite social media’s role in providing information and serving as a means to connect during the pandemic, it has also been linked to increased anxiety and potentially negative effects on protective behaviors and self-efficacy [
21,
22,
23].
The widespread use of social media poses a challenge to ensuring the accuracy of information. Participants also exhibited a common misconception regarding the susceptibility of individuals with other health conditions to COVID-19, indicating a lack of awareness about the factors that increase the risk of contracting the virus. In another study conducted in Indonesia, COVID-19 questionnaires were distributed using the social media app WhatsApp. The results revealed a stark contrast to our study, with the majority of participants demonstrating a high level of knowledge (98%) and positive attitudes (96%). One notable difference between the two studies is the educational background of the participants. In our study, the majority have a high school education (59%), whereas in the other study, the majority have a bachelor’s degree/S1 (57.7%) [
24]. Similarly, a study conducted in Jakarta in mid-June 2020 also showed positive attitude results, with over 70% of participants exhibiting good attitudes and 66% having a higher educational background [
13]. These studies, conducted through online platforms, consistently show positive outcomes among participants with higher educational levels, including diplomas and undergraduate degrees.
In contrast, our current study distributes physical questionnaires, resulting in a participant pool that is more diverse in terms of educational and socioeconomic backgrounds. This diversity reflects a broader representation of grassroots communities, rather than those who are more educationally privileged. These differing characteristics between studies may explain the varying abilities of participants to discern information circulating about the pandemic. These findings highlight a misunderstanding among participants regarding their vulnerability to COVID-19. Participants’ perceptions of their likelihood of infection differ from other studies that show a high perceived risk, even though it is in line with the result of study instrument reference number 5 [
19]. This discrepancy could be due to participants’ unfamiliarity with pandemic settings, leading them to perceive COVID-19 as a mild illness similar to common respiratory infections.
Another study in a different sub-district of Medan showed a higher percentage of positive attitudes (95%), despite having a similar majority of participants with senior high school education. However, the occupation demographics differed, with 30% of the participants in the other study being business owners, whereas this study was predominantly composed of participants in other categories, including housewives and online taxi drivers [
25].
The majority (75%) believes that COVID-19 could significantly damage their health; they simultaneously perceive themselves as at low risk of infection, indicating a misunderstanding regarding vulnerability to the virus. This indicates a prevalent negative perception among participants regarding the risk of COVID-19 infection. Another study explored the perceived risk as a whole in Indonesia, resulting in the same low-risk perception [
26].
Additionally, a substantial portion (63%) disagreed with the idea that smoking increases the risk of COVID-19 infection. Many participants do not agree that factors such as smoking history increase their risk of infection. This contrasts with research suggesting an increase in smoking tendencies since the pandemic began [
27]. Furthermore, the fact is that smokers are more likely to experience adverse effects from a COVID-19 infection than non-smokers, with one study displaying an increased risk of 1.53 times [
28].
Even if so, participants demonstrated good knowledge, with the majority (60%) answering correctly. Knowledge of symptoms, method of transmission, and what the term close contacts means are the questions with the highest number of correct answers. Acknowledging the symptoms and method of transmission is essential for preventing the disease by assisting in early detection; the results are similar to studies conducted in other countries [
29,
30,
31].
Regular handwashing with soap or using alcohol-based hand sanitizer, minimizing in-person contact and practicing social distancing, wearing a face mask in public places, and avoiding going to public places unless essential are among the precautions, even if it is only 62% of the participants’ answers contains those activities, which is lower than the questionnaire reference [
10]. On the other hand, less than 20% of the participants know that people with comorbidities (ex: diabetes and hypertension) are more susceptible. A study has proven how COVID-19 infection impairs glycaemic control in diabetes by increasing inflammation and altering the nature of the immune system’s response and, therefore, increases the risk of complications in diabetic patients, leading to the development of thromboembolism or cardiovascular and respiratory failure [
32]. Hypertension alongside other cerebrovascular diseases is independently associated with in-hospital mortality and intensive care unit (ICU) admission, although, given the established role of hypertension as the principal risk factor for cardiovascular diseases, this association may not necessarily be limited to COVID-19. In addition, a large fluctuation in BP in COVID-19 patients with poor prognosis may simply reflect their critical conditions [
33,
34,
35].
Addressing these misconceptions and attitudes is crucial in developing strategies to prevent the transmission of COVID-19. Public health interventions should aim to educate the public about the risks associated with COVID-19 and promote behaviors that reduce transmission. The study identified several behaviors among participants that are not recommended for preventing the transmission of COVID-19, as shown in
Table 6. These include regular exercise (45%), regular consumption of garlic (39%), and regular use of antibiotics (34%). These findings align with a previous study conducted in England, which reported similar rates of antibiotic use (36%) to this study (34%) [
12]. This suggests widespread misinformation regarding effective prevention measures for COVID-19.
Both attitude and practice showed a correlation with age, specifically where the age is above 60 years old. This result is similar to a previous study reporting older people have adopted prevention practices for COVID-19 more than the other age group [
31], albeit 50% of the age group is above average in knowledge and 61% answered correctly regarding whether having comorbidities can affect susceptibility. This is higher than other age groups. The elderly are in a riskier position, with aging bodies and commonly carrying comorbidities; navigating through the pandemic requires them to be more aware and vigilant towards possible transmission [
36].
The study’s limitations include its cross-sectional method, which limits its ability to show changes over time. It focused on only one of the districts with high case numbers, potentially limiting its generalizability. Having been conducted at the beginning of the pandemic may represent the fresh panic wave of the pandemic. But, it is susceptible to changes as time goes on within the pandemic, and the government advances to prevent transmission. Future research should consider the dynamic for a more detailed understanding of informed policy revisions and their implications.
