1. Background
Coronaviruses are a subspecies of Coronaviridae and are a large family of viruses that can cause a wide range of illnesses, from the common cold to more severe illnesses such as MERS, SARS, and COVID-19 (1). COVID-19 was first discovered in late December in Wuhan, China (2). As it had a high rate of spreading, it soon reached other cities in China and then all parts of the world (3), so that it was declared a pandemic by the World Health Organization (4). It has affected many countries globally, and the number of confirmed cases and deaths has increased increasingly (5). On February 20, 2020, the first confirmed case of COVID-19 was found in Iran in Qom (6). In Iran, as in other countries of the world, the number of cases and deaths has increased (5).
About 81% of COVID-19 patients have a mild illness, and only 14% of cases have a severe form, while 5% experience the critical phase of the disease. However, the fatality rate of this disease is higher in older people with underlying conditions (7). The disease is associated with symptoms such as cough, fever, fatigue, sore throat, pneumonia, diarrhea, headache, and shortness of breath (8) and can be transmitted by coughing and sneezing in close contact (approximately one meter) and contact with equipment and objects the infected person has touched (9, 10). Currently, there is no officially approved antiviral treatment (11), so one of the most important ways to prevent this disease is to use personal protective equipment (such as a facemask), frequent handwashing when leaving the house, not to have close contact with suspected or positive COVID-19 cases, and not traveling to high-risk areas (12).
Knowledge, attitude, and practice (KAP) studies are one of the most widely used studies in the field of health-related behaviors in the population (13) and are used as an essential tool to control and prevent epidemics (14). Such studies show the extent to which people in the community are concerned about the issues related to their health (15). On the other hand, preventive interventions in a population effectively control the disease when the difference between the knowledge, attitude, and practice of people about a disease is known before the implementation of interventions (16). Given the experiences and evidence of epidemics of Ebola, Middle East Respiratory Syndrome (MERS), and Severe Acute Respiratory Syndrome (SARS) (17-20), the awareness, attitude, and understanding of the risks of an epidemic can play an essential role in controlling the disease. Thus, evaluating individuals' knowledge, attitude, and practice is very necessary as it can prevent the transmission of the disease and help control it. It also influences people's behaviors and provides a basis for behavioral change according to national and international guidelines.
People of Iran have already experienced four waves of coronavirus disease, and in the meantime, they have received much information about this disease from the media, the Health Ministry, and health centers. Therefore, the question is that after 18 months since the onset of COVID-19 in Iran, are the people’s awareness, attitude, and preventive measures of this disease at a desirable level?
2. Objectives
The purpose of this study was to determine the level of knowledge, attitude, and practice taken by the general population of South Khorasan province about the COVID-19 pandemic and the influencing factors.
3. Methods
3.1. Study Design and Population
This online cross-sectional study was conducted in eastern Iran on the general population of South Khorasan province, with the capital Birjand. To collect data, we designed an online questionnaire with questions on demographics including age, sex, marital status, education level, occupation, residence place, income, and residence area in South Khorasan. There were also questions on knowledge, attitude, and practice derived from the instructions of the Ministry of Health of the Islamic Republic of Iran, WHO, and KAPs of previous epidemics (MERS and SARS). Also, a question about the source of information about COVID-19 was added to the questionnaire (18, 20-22).
Experts in the field, including 10 public health and epidemiology experts, were then asked to review the tool and provide feedback on the simplicity and comprehensibility of the questions relevant to the target population and their relevance to COVID-19. According to the Lawshe table, the minimum CVR value for each question should be 0.62, which was higher for all questions in our study. Also, according to the Waltz and Basel method, the minimum acceptable value for the CVI index for each question should be 0.79, which was higher for all questions in the pretest of our study. Also, S-CVI/Ave was calculated to be equal to 0.93. Then, a pilot study was conducted on 18 citizens two weeks before and after the test. The reliability value based on Kuder-Richardson for the questionnaire was 0.81, and the intra-cluster correlation in terms of knowledge, attitude, and practice was estimated to be 80, 76, and 71%, respectively.
3.2. Instruments
This questionnaire included 34 questions. There were 15 questions on the knowledge, including items 1 to 15 (score range from 0 to 15), 12 questions on attitude and risk perception of the disease including items 16 to 27 (score range from 0 to 12), and seven functional questions on taking precautions to prevent the disease including items 28 to 34 (score range from 0 to 7). The options were "correct," "wrong," and "I am not sure". People got one score for a correct answer to each question and zero scores for wrong or unsure answers. In general, the higher the scores of people in these areas, the higher their knowledge, attitude, and practice.
3.3. Procedure
The questionnaire was designed electronically, and its link (www.cafepardazesh.ir) was distributed on social media through Telegram and WhatsApp in South Khorasan province in several stages. Questionnaires completed earlier than one minute or later than one hour were excluded from the study. The participants were chosen by a convenience sampling technique.
3.4. Statistical Analyses
Data analysis was performed using SPSS version 24 (IBM Corp., Armonk, NY, USA) at a 5% error level. Descriptive statistics such as frequencies, percentages, means, and standard deviation were used to summarise qualitative data. As the data were normal, an independent t-test, one-way analysis of variance, and Pearson correlation coefficient were used.
3.5. Ethics Statement
This initiative complied with ethical standards set by Birjand University of Medical Sciences and the Declaration of Helsinki. Also, this research was approved by the Ethics Committee of Birjand University of Medical Sciences with the ethics code of IR.BUMS.REC.1399.023. Informed consent was obtained from all individual participants included in the study.
4. Results
A total of 699 participants completed the survey questionnaire. The mean age of the participants was 28.90 ± 9.58 years. Among the participants, 61.51% were females, and 38.49% were males. Besides, 89.2% of participants were from urban areas (Table 1).

Reported sources of knowledge about COVID-19
The mean knowledge score of the subjects was 21.94 ± 4.05 out of a maximum score of 30. Besides, 97.20% of people were aware that COVID-19 was contagious. Also, most participants (98.30%) agreed that people suspected of the disease should be isolated from other people in the community. The majority of people were well aware of the disease transmission ways, and only 1.30% said they were unaware. Also, the most common symptoms of this disease were shortness of breath, dry cough, and fever or headache, in sequence (Table 2). The mean score for the subjects' attitudes was 9.61 ± 1.81 out of a maximum score of 12. Besides, 87.20% of the participants considered COVID-19 dangerous, and more than half (56.90%) felt at risk of contracting the disease. Accordingly, most people (81.70%) mentioned getting the vaccine if it was available (Table 3). The mean scores of the subjects’ practice were 5.94 ± 1.76 out of a maximum score of 7. Also, 94.80% of the participants stated that washing their hands with soap and water frequently was one of their actions, and 86.80% preferred to stay at home to cut the disease's transmission chain (Table 3).

5. Discussion
This study aimed to determine the level of knowledge, attitude, and practice in the general population of South Khorasan province about the COVID-19 pandemic and its influencing factors. In the present study, the people's knowledge in South Khorasan province, Iran, about COVID-19 was moderate (21.94 ± 4.05 out of a maximum score of 30), indicating a 73.13% knowledge and awareness level.
Middle-aged people showed a higher level of knowledge than other age groups, possibly because this age group follows information and news more. In a study conducted by Abdelhafiz et al. in Egypt, the level of awareness of individuals was reported to be 74.50% (23), which is similar to the present study. In studies from other countries, a percentage between 63 and 99.50% was reported (6, 24-27). These differences can be due to different measurement tools, sample sizes, cultures, and study time in different countries. The primary source of information about COVID-19 was the national television (490 people, 71%) and social media such as Telegram, WhatsApp, Instagram, etc. (447 people, 64.8%). Apart from a similar study conducted by Honarvar et al. in Iran (6), numerous other studies have cited social media as the primary source of information for individuals (23, 26-29). In recent years, due to the advancement of technology and the ease of access to the Internet, the desire of people to use social media has increased (6), but according to specific rules in Iran, many social media apps are filtered, and not all the people have easy access to them.
In addition, 85.50% of the people in the present study considered COVID-19 a virus, and over 97% of them agreed that the disease was contagious and people suspected of the disease should be isolated from the rest of the community. The incubation period, transmission routes, and symptoms of COVID-19 were also well known to the participants. These findings are consistent with Reuben et al.'s (26) and Lau et al.'s (30) studies. These studies also assessed knowledge about the incubation period, transmission routes, and symptoms of COVID-19 at a reasonable level (above 86 and 89.50%, respectively). However, in the study conducted on Indians, people's knowledge about this disease was deficient, so that this rate was between 7.7 and 18.2% for the main symptoms of the disease, such as fever, cough, shortness of breath, etc. Also, 29.5% of people considered touching, kissing, sneezing, and eating as the ways of transmitting the disease, and 57% did not consider this disease contagious (31).
The attitudes of individuals can play an essential role in controlling diseases; in fact, they are a bridge between awareness and practice that can make the connection between the two easier, ultimately leading to behavior change (32). Most people in the study had a high understanding of the risk of transmitting the disease, and up to 85% were worried about having a family member with the disease. Besides, almost a little over half of the people felt at risk. It is in line with the study of Honarvar et al. in Shiraz, Iran. In this study, like our study, almost half of the people felt threatened by this disease, and most of them were worried about their families contracting the disease (6). According to a study by Huynh et al. in medical staff, almost 80% of people were worried about themselves and their families contracting the disease (11). Also, 86% of Egyptians considered this disease dangerous, and 86.9% worried that they or their families would be infected (23). The discrepancy between Iranian studies and other worldwide studies concerning the lack of deep concern of people about the risk of disease in Iran can be due to that in the present study, most of the participants were young and believed that the disease could be dangerous only for the elderly and those with underlying diseases, which has already been confirmed in some studies (33, 34). Also, the role of Iranian media in making this disease seem less important for young people and individuals without underlying diseases in the early days of the epidemic has created this belief in people, especially adolescents and young people, that this disease cannot be too dangerous for them.
Most people (81.70%) mentioned that they would get the COVID-19 vaccine if there was one available, while the Nigerians had little faith in this, and only 29% of them would get vaccinated. According to the author, this could be due to the fear and misconceptions created by the media about the health risks of these vaccines (26).
A total of 84.85% of participants took measures to prevent the COVID-19 disease. Of them, 94.80% washed their hands, and more than 76% of them used facemasks and threw them in the trash after use. These rates on the use of facemasks and handwashing are higher than those of Honarvar et al. and Azlan studies so that the desire of people to use masks was approximately 60% and 50% and the desire to wash hands was 80 and 87% in these two studies, respectively (6, 24).
The results showed a significant positive relationship between knowledge and attitude, knowledge and practice, and attitude and practice, which is consistent with the results of other studies (6, 26, 29). Therefore, increasing knowledge and changing attitudes can change people's behavior positively (33).
Our findings also showed a significant relationship between age and education level of individuals and their practice in the prevention of COVID-19, which is consistent with the results of studies conducted by Honarvar et al. (6), Lau et al. (30), and Zhong et al. (27). Age and education level are two factors that make a person experience over time; in fact, with their increase, a person's experience also increases, strengthening the person’s performance in critical situations.
5.1. Study Limitations
Due to the electronic implementation of the present study, limited access to telephones and the Internet in the villages, and the low level of literacy of rural people, the number of rural participants in this study was low. As the Iran health system is coherent and readily available for people in rural health centers and homes, it is suggested that future studies be conducted on these people and their information be collected in person. In addition, the chances of weak and vulnerable people, including the elderly, the illiterate, and the unemployed, were low to participate in the study, which certainly affected the KAP score. Also, as electronic questionnaires were used, random sampling was not possible. Besides, many people could not participate in the study due to the filtering of social media applications such as Telegram in Iran. However, in this study, we tried to use other social media apps that were readily available, such as WhatsApp, to solve this problem.
5.2. Conclusions
Despite that the level of knowledge, attitude, and practice of people was good regarding COVID-19 in this study, the continuous informing of the people through television, radio, and social media is needed for maintaining the status quo. Besides, new approaches and policies for the poor, rural populations, the elderly, the illiterate, and the unemployed should be adopted by relevant authorities due to their lower level of knowledge and practice.
