2.1. Social Media and Public Health
Social media is determined as a web networking that permits reach, format, and interchange of content that is universally available [
12]. Social media networks can facilitate people’s communication to interchange information. It has altered the method people interact with each other, also including health conversations [
13]. According to Dredze [
14], people can share information and search for a topic on Twitter, so people can tweet health topics over the public health community to get specific advice or solutions. The healthcare sector, covering medical centers, health regulations, hospitals, professional associations, pharmaceutical corporations, and patient support groups, employs social media for numerous objectives. It can assist healthcare experts and patients’ communications regarding health cases that can bring new changes and challenges to the health care sector [
15].
Health content on social media platforms lately has been progressively sent from devices and mobile phones, which supports the opportunity to carry geographic data [
16]. Medical descriptions are more beneficial, and social media tools permit data to be presented in various forms. For example, videos on YouTube can be adopted as a substitute for written messages in the fields with low knowledge rates, where individuals cannot read medical records [
17]. Likewise, a variation of other forms of social media is applicable to motive debating between patients and comfort specialists [
18,
19]. These channels consist of Twitter, Myspace, Blogs, Wikipedia, and Email, besides Facebook that is managed on an extensive measure to spread medical materials referred to epidemics, clinics, drugstores, and examination by the diseased person and health specialists [
20]. In addition to companies in the private sector, health concern agencies and public health institutions locally and nationally and are using Twitter as a prime electronic platform for the education and enhancement of health, as the more significant part of the content on Twitter is overtly ready and may provide an origin for health-concerning information [
21]. Twitter is a free network on social media with over 100 million energetic users throughout the day. Despite its extensive adoption by healthcare experts and professionals, there are few studies on the shapes of hashtag use on Twitter and a lack of manifest research concerning its influence on public health. In [
22], Seymour stated that planned social media use, such as hashtags, may be an efficient method for organizations to transmit precise information to the audience through a period of crisis [
23]. Users may be guided to links and pursue private health foundations and service providers for accurate geographic-related information. Examiners may utilize general available “big data” such as local tweets to measure the hazard interaction efforts of native agencies [
23]. For example, public authorities were able to track people’s sentiment toward the Zika virus’s breakout through the analysis of Yahoo! Answers. Public reactions became less aggressive as the government published more answers about virus prevention and treatment [
24].
Public health is “the discipline and profession of avoiding infection and diseases, continuing existence and improving individual health via coordinated intentions and educated preferences of communities, institutions, general and private societies, as well as humans” [
25]. Previous researchers Korda and Itani [
26] have investigated the implications and effectiveness of utilizing social and digital media to promote public health and disease prohibition efforts. So, the platforms of social media assist people in connecting to health-encouraging messages, and the content of the message itself can create a public that is mindful of their health conduct. If the public is motivated and start spreading these messages through social media channels, then this behavior shape general ratifies the health attitude. Consequently, sharing health messages through social networking channels matches two primary standards: alteration of conduct and general obligation [
27]. Over the engagement of social media platforms, public health foundations can share related content anywhere users spend their time [
28].
Additionally, studies have shown that digital advertisements can be a useful tool for campaigns to extend to niche viewers, who are the receivers of the content. Digital and social media ads can strictly objective inhabitances according to their features such as geographical areas, gender, age, and interests. They can increment campaign range and are the most excellent strategy to transfer communications to the most significant amount of the concerned audience. Because ads can be purposely placed, and views can be ensured, the prime measurement of the success in ads is the reached public [
29]. According to the researchers, George et al. [
30] assume that social media has an immediate public health relation because media networks could substantially affect health conduct and outputs. However, organizations related to public health have not yet utilized social media’s real chances [
31]. Chou et al. [
32] mainly investigated the necessity for public health’s interference to use social media’s interaction environment. Heldman et al. [
33] proposed that foundations of public health and practitioners frequently utilized social media for the conventional one-way transmission of information; instead of engaging audiences in modern ways for interaction such as two-way communication, or what is called “indeed social”.
Social media could encourage healthy lifestyles to increment public health awareness via exercises and healthy diets [
34]. For this reason, public health awareness activities are prepared every year to update the information of health hazards and interactions during a particular period, which could be for days, weeks or months. The amount of public awareness campaigns has significantly increased [
35]. Social media can collect information concerning hospital and doctor’s performance based on their patients’ experiences [
36]. It is also applied for health progress and health studies. Furthermore, it can be noticed that sharing healthy materials and information such as learning from other people and increasing health education and knowledge are primary reasons for which patients adopt social media platforms and the web referred to healthcare [
37]. Thus, a significant investigation is that electronic campaigns can attain great reach at a relatively minimum cost [
38].
Healthcare can be perceived and better comprehended by patients if they have health-generated content on social media [
39]. Individuals would rather have electronic information about health over the device they are most usual with, according to what was investigated in an Australian survey [
40]. Notably, youthful people favor obtaining health information via the Internet or by social networking means; however, older adults favor newspapers. Hereafter, these preferences would be directed through online choices towards a scope of age categories. Nowadays, a different method is suggested according to previous evaluation of social preferences. Most studies on preliminary care preparation include people above 65 years; a new direction is now implemented toward including and instructing many younger people; therefore, they are more ready to interact with these issues in their societies and families. One study looks to students at US universities and suggests that an essential part of public health is issuing credible information related to preliminary care preparation to youthful people [
41]. Additionally, over half of US grownups in all ethnic and age categories use the web to look for health materials and information [
42].
2.2. Social Media and Public Health Awareness of Infectious Diseases
Infectious diseases are the contagious diseases generated by various kinds of infective micro-organisms, such as microbes, germs, viruses, and parasites, and these forms of infections can be transmitted instantly or indirectly from one human to another [
43]. The World Health Organization (2020) determined the outbreak of COVID-19 on the 30th of January in 2020, stating that is was a “public health emergency of international concern”. Scholars quickly began working to explain the pandemic characteristics, covering its ability to transmit, death rate, and emergence [
44]. Both the World Health Organization (WHO) and offices for disease surveillance and prohibition provide regular communications through social media and website upgrade networks. At the time of the crisis of public health, it is crucial to communicate instant information to the mass population in the actual period while tempering media subjection that can drive to traumatic stress reactions and related diseases. As authenticated society agents, health care experts also play an essential part in contacting necessary information to ill people and other society members. Workable guidance that persons can apply to be safe from infectious microbes and viruses include the cleaning of hands, the use and instant disposal of hankies for sneezing and coughs, the sterilization of surfaces, and social distancing are all beneficial, while at the same moment working to block other mutual infections such as influenza [
45].
Therefore, publicists and public health administrators worked to transfer crucial information worldwide related to risk valuation and suggestions, and concerned warnings appeared regarding the psychosomatic suffering generated from repeated media subjection to the outbreak. This has included the instant suffering in the inhabitants previously struggling with unmatched economic and social collapse and the downstream impacts on mental and physical health [
45]. Furthermore, these tension responses can increment help-searching conduct that may be odd or not endorsed in answer to the current risk, overloading health concerns facilities and redirecting crucial resources. For example, a phobia of purchasing primary consumers materials such as first-aid packages, toilet paper, bottled water, alcohol and chlorine sprays, and hand sanitizer in reaction to COVID-19 has driven to worldwide shortages price leveraging of substantial requirements [
45]. Throughout the health emergency, the audience relies on media channels to transfer precise and modern information to make knowledgeable decisions about health defensing behaviors. Through crises and risks, the dependence on media will be increased and the sources must be credible and accessible to provide hazards appraisals and recommendations [
23].
Social media are playing an active role in transmitting prompt caution signs to public health officials to make an update path of work to prohibit and monitor the spreading of those diseases [
46]. It is also a helpful tool for the active interaction for the new updates regarding infectious disease’s news and primary medical details to the audience. These kinds of diseases appear to have hazards to the public, who frequently switch to conventional media and social media to obtain information [
47]. So that the audience understands the risks that can be shaped and constituted by describing and communicating about infectious diseases via social network channels, which can have a significant influence on their behaviors and decision making, Patel et al. [
40] advise utilizing social media to support different areas: emotional, empirical, and social.
Several investigators have discovered increasing the conventional alerting networks regarding the disease occurrence with statistics exported from Twitter. Through manually investigating a massive number of tweets, which presented that reports coming from individuals themselves about their symptoms are the utmost credible sign in examining if a tweet is related to an outbreak or not, new trends of diseases and infection’s outbreaks are studied and captured by scholars, often influenza, by observing social media channels regarding infectious diseases [
48]. Other investigators concentrate on new elaborate designing of the tweet’s style and language and their relation to public health in common and to forecast influenza specifically [
49]. Furthermore, wealthy contents can be utilized to find out local health update movements, making digital monitoring of contagious diseases reasonable [
50].
Suitable time to identify the flare-up of the infectious disease is a sensitive issue, for both active starting of public health interference and surveillance actions, in addition to the appropriate time to notifying government organizations and audiences at massive. The observation ability for such revelation can be costly; public health infrastructures in many countries have a shortage to determine an outbreak at its advanced stages. Web networking is changing how pests and epidemic intelligence work, and it suggests a resolution to these limitations [
46]. Governments universally are starting to utilize the web and information technology in an effort to direct citizens’ needs for more important information available, transparency, and gain entry to general services. One network during which the previous goals are being followed is social media, which cover connecting sites, such as Twitter, YouTube, and Facebook [
51].
2.3. Social Media and Public Health Behavioral Changes
The diffusion of usage of social media channels can as well impact the behaviors related to public health and objectives through the social build-up since human beings are very social, they are frequently affected by their families, as well as by friends, and by mutual friends [
47]. The campaigns generated by social media can immediately or indirectly impact behaviors related to health towards considerable inhabitants. Thus, conscious planning of the subjects and the materials of campaigns, and their match with the target audiences are essential. They are perceived as a reliable way of preventing diseases and the efficiency of its costs [
52]. Research on social marketing campaigns, involving Internet campaigns, proposes that they can impact people to alter their conduct and attitudes [
53].
A substantial constraint for social media campaigns’ success is that humans should sense trust in the materials and information given. An example shows that an appraisal for TV ads in Canada regarding health improvement pointed at older adults showed that people who receive were mostly doubting the data if they recognized that it was sent by the government. Experts such as doctors or famous persons were viewed as more reliable. The outstanding benefit of applying social media in healthcare is the understandable accessibility of material linked to infections, diseases, treatment strategies, and remedies [
54]. A powerful incentive is emotional support provided by connecting with humans influenced by the same illness and simplifying the diffusing of updates regarding the newest medications. This connection is not restricted between patients; it enhances the relationship between patients and healthcare experts. In an expression of price, the area of a specific facility, and the remediation excellence, it will assist in contrasting diverse services suppliers in the attainable zone [
54].
Social scholars have examined that media channels and technology have a further immediate impact as being an orderly part of youth individual’s social and behavioral experience. It has been suggested that technology and media are now a part of the environmental framework of human beings. Keeping in mind the relevance of environmental elements on health behavior, it would be rational to check the relation between youth mature social media usage and health conduct [
55]. New technologies and media such as movies, Internet and video games are conceived as stationary activities that replace exercise, which over time lead to increases in the body mass index (BMI) of children and youth [
56]. With technological interchange and the capability to reach diverse technologies from a single device, a considerable number of youth have gained access to social media channels on their mobile phone and can choose to use them at any time, which could be a signal for an increment in passive behavior. The interactive pattern of social networking sites may have various effects on youth and their health behavior, more so than unresponsive technologies such as movies, TV, and music. Investigators have determined that social participation can influence food preferences and selections amongst young people [
57].
Therefore, examining messages and conduct on social media might give a special vision for the potential impacts of information concerning health connecting vast audience segments [
31]. Data circulation on social media can profoundly impact people conduct and attitudes and change the efficiency of the countermeasures installed by governments. For this reason, patterns that predict virus diffusing begin to consider behavioral reactions of the public about general health involvement and the interaction drivers behind consuming the content [
58]. The short interference by campaigns on social media regarding public health has been seen to have a significant influence on optional conduct change [
38]. As solid proof indicates that public health promotion campaigns managed via social media can have an immediate and positive impact on behavior [
52].
Furthermore, differences within generations in social media use are also an important factor in changing behavior toward health. Web users’ choices and the usage of electronic channels also vary by ethnicity, gender, income, and education features. Women are more probable than men to look for information regarding symptoms, remediation, infections, diseases, and drugs. Men to a greater extent are more likely than women to search objectively for supplements and vitamins, agencies for health insurance, and medical practitioners; both women and men were equally likely to search for wellness and healthy subjects; and men are more likely to utilize social media than women. Therefore, developmental studies concentrated on comprehending the interests, essential values, and desires of the public that assist the content to be culturally applicable and sense creditable. The results assessment will assess the differences in attitudes, conduct, knowledge, and beliefs to define behavioral actions variations. The feeling of empowerment in deciding somebody’s health can be an essential part of assisting individuals in looking at lifestyles and good health behavior. Various studies have noted that internet interference had a considerable positive impact on empowerment. A new examination to measure the efficiency of web interference in raising patients’ empowerment contrasted with regular care by face-to-face interventions found a significant impact on empowerment as valued on self-efficiency extent and scales of proficiency [
59]. Other studies appear that patients would experience their health decisions through online learning, discovering they have increment confidence in asking health providers questions and information to assist them to run their situations [
60].
Global mandates to promote public health, depending on modifications in an extensive collection of behaviors, such as bodily activities and nutrition programs, to smoking and substance use to the commitment to therapy and examination rules. Consequently, attempts to match these mandates rely on interference procedures efficiently amending the audience’s behavior to public health [
61]. An example of health awareness campaigns are that an entire campaign was formed that contains the Fresh Empire website’s foundation as a health brand. Health awareness is a plan that utilizes marketing rules to promote substantial behavior change [
62]. To create the brand and transfer the campaign content, the master plan incorporated various messaging platforms to smooth the range and interaction. The content channel for Fresh Empire contains paid and organic social media, digital ads, broadcast and a website, plus events. To engage the teenagers on the networks they use generally, there is an intensive digital concentration.
