The study indicated medium levels of health knowledge and health behaviors among people. Furthermore, from their perspective, the public policies on COVID-19 control were assessed at the medium level. Although the general knowledge of COVID-19 was assessed at a medium level, there were some false notions among people, and nearly half of the people believed that the use of garlic and herbal drinks is effective in the prevention of COVID-19, while their preventive effects have not been confirmed by scientific evidence (
9,
10). Similar to our study, in Jordan and Nigeria, nearly half of the respondents believed that honey, ginger drinks, garlic, and local soups are helpful in the prevention of COVID-19 (
11,
12). As well as in the US and England, 10% of the respondents believed that garlic is useful (
13).
Our study showed that nearly 20% of the participants believed that alcoholic drinks are effective in the prevention of COVID-19; however, according to the WHO, alcoholic drinks do not act as a preventive factor and can even be dangerous (
14). Our results emphasize that health education interventions should focus on the replacement of myths with correct beliefs in Maragheh. In this study, 89% of the respondents had knowledge about the necessity of wearing masks. In another study, 82% of Iranian students stated this necessity (
15). The difference in the results of these two studies could be due to the fact that the second study was conducted at the beginning of the COVID-19 epidemic when the emphasis on wearing masks for the public was low. The necessity of wearing masks was reported by nearly 75% in the US and 70% in England (
13).
Regarding people’s knowledge of COVID-19 symptoms, this study indicated that cough, fever, and dyspnea were the most prevalent reported symptoms. These results are consistent with other studies (
13,
16). More than half of the respondents declared that the ability to hold breath for 10 seconds, as mentioned in some social networks in Iran, is one of the important signs of being healthy. Hence, it is essential to raise people’s alertness to the unreliability of inaccurate news and information. According to the results, there was no significant relationship between health knowledge and demographic characteristics, and only respondents with a PhD degree had higher levels of health knowledge. In this regard, the results of similar studies in Egypt, the US, and China were consistent with our study (
17-
19).
This study indicated people’s health behavior at an average level. In a study of Iranian medical students, their knowledge and behavior on COVID-19 were evaluated at high levels (
15). Apparently, this difference is expected because medical students have more knowledge about the nature of the disease. In this study, washing the hands repeatedly and wearing masks and gloves as permanent behaviors have been reported less than other behaviors. Regarding mask-wearing, a number of studies contradicted our research results (
19,
20); however, all or most of the people were not in the habit of wearing masks in Iraqi Kurdistan (
6).
Given the fact that the respondents in this study had relatively high levels of knowledge about wearing masks and gloves, health promotion interventions should focus on turning knowledge into protective measures. In our study, more than 10% of the respondents reported that there was no need to wash hands while wearing gloves, a finding that shows the false trust in gloves was considered a protective tool and the necessity of improving the public awareness of the correct use of protective tools.
In this study, women’s health behavior was higher than men. Similarly, in Italy women had significantly higher levels of health knowledge and behavior compared to men (
20). Previous studies indicated that different factors such as old age, femininity, and higher educations correlated with higher probabilities of adopting protective measures (
21). According to our results, people’s knowledge predicted health behavior. In the US and China, protective behaviors are directly correlated with health knowledge (
19).
In this study the policies were adopted for social and physical distancing, closure of syndicates and schools, constraints on intercity trips, and teleworking were evaluated effective more than other policies. Accordingly, the results of this study were consistent with those of other studies; for instance, policies on quarantining, all of those arriving from other countries, constraints on all air trips, and prohibition of any gatherings were considered effective interventions by the people in England and the US (
5,
13,
22).
In the current study, the participants believed that it was essential to improve the coordination between different public institutions to contain COVID-19 and implement systematic strategies to deal with the social harms.
In general, serious challenges to COVID-19 control policies in Iran include the insufficiency of the whole-government and whole-society approach to crisis management and delay in decisive governance (
23). By contrast, in a few countries such as Norway where the COVID-19 crisis was managed successfully, the evidence indicated that the crisis management required both governance capacity and policymaking potential (
24). A collaborative decision-making style can be beneficial with a background of high social trust among citizens through the involvement of all stakeholders and participation of governmental players and citizens (
24). Moreover, Taiwan managed to contain COVID-19 by using a collaborative governance model in comparison with similar countries (
25). South Korea succeeded in containing the spread of the coronavirus by identifying, quarantining, and tracing infected and exposed cases actively, transparency in the presentation of up-to-date statistics on death, and voluntary participation of the public and without applying any strict policies (
26).
Based on the results of this study, people believe that it is essential to procure adequate equipment for the treatment of patients at healthcare centers and formulate responsive policies on the long-term control of COVID-19. It appears necessary to take the needed governance actions on the procurement and availability of personal protective equipment (
27).
5.1. Limitations
This study had potential limitations. First, although we tried to include all individuals from different sociodemographic groups in our sample population, it may not be representative of the whole society. Second, it was possible that participants looked up the answers to some questions online before answering, which might cause bias in the results (
28). Third, there was the likelihood of sending a questionnaire to two phone numbers of one person. Forth, we could not check what percentage of responders in each zone have filled the questionnaire. lastly, not all of the population of the city (or the population over 16 years old according to the inclusion criteria) had access to a mobile phone, but due to the need to conduct the online study during the conditions of Coronavirus, there was no better way to collect data.
5.2. Conclusions
During conducting this research, Maragheh was one of the 43 cities in the country with a very dangerous situation; so considering the moderate level of health knowledge and behavior, increasing knowledge level and correcting the wrong opinions of people should be considered in health education interventions in the community. It is also important to strengthen regulatory levers to evaluate the implementation of health protocols by the syndicate. Furthermore, some policies such as the closure of high-risk syndicates and travel restrictions can be re-implemented because they are more effective strategies based on public opinions so will be more acceptable throughout the community.
