The Spanish flu, the Asiatic flu, the SARS, the Swine flu, the Ebola affected people worldwide. They affect people's behavior and psychology. People who are faced with potential pandemic threat, are prone to develop recommended and avoidant behaviors to protect themselves (Zhou et al., 2020). Behavioral sciences seek to understand psychological, biological, social, and environmental factors that may influence behavior development in infection control (West et al., 2020)COVID-19 not only challenges for change in behavior, but also affects people’s mental health (emotions and cognition) (Zhou et al., 2020). Mental health serves also a crucial role in combating a pandemic with effecting the world environment for protecting viral outbreaks. Psychosocial effects for these epidemics or pandemics included recommended or avoidant behaviors, emotional distress and protective responses like COVID-19 (Zhaia & Du, 2020 ; D et al., 2020) COVID-19 has adverse effects on brain, that can influence for economic downturn, quarantine, social isolation, unemployment, homelessness, insomnia , indignation, sensitivity to social risks , life dissatisfaction , phobias , behavior change (avoidance , recommended behavior) and physical symptoms (D et al., 2020) , perceptions factors. Although there is an association with suicide, anxiety, emotional distress, risk of post-traumatic stress disorder and depression. COVID-19 treatment (e.g., vaccine), local outbreak, hand hygiene, wearing a mask has an association with psychology (Wang et al., 2020). Knowledge can influence the perceptions of the people although for COVID-19 it's unclear (Bhagavathula et al., 2020). In Pakistan, corona virus has reduced shop visits by 88.8%; reduced physical contact by 86.5%; 74.5% inspect healthcare facilities; 84.5% cancelled plans; and 87% washed their hands often (Balkhi et al., 2020). But in Bangladesh, reduced shop visits by 30%; reduced physical contact by 54%; 48% cancelled plans; and 28% washed their hands often. That’s why Pakistan COVID-19 situation is better positioned than Bangladesh. COVID-19 creates psychological burden (social and broader behavior). Aligning behaviors does not have long-term effects (Bavel et al., 2020).
The prevalence of anxiety in Pakistan was between 62.5% and avoidance behavior (P = 0.04) as a result of social media use among those under 35 years of age (Bavel et al., 2020). Italy, China, Singapore; Less anxiety was associated with higher efficacy (confidence in the ability to protect oneself from infection). High-level of anxiety were associated with higher scores for prejudice and casualties, and the traditional media as a reliable source of information for both Singapore and Italy (Lim et al., 2020). But in Bangladesh the prevalence of anxiety was 82%. The level of anxiety and changes in behavioral responses to anxiety may be influenced by the information provided. Hand washing education and information are important but not enough to change habits. Messages that draw attention, facilitate consent, and mention abomination increase the use of alcoholic hand sanitizers. Interventions to touch appearance need to change the physical and social environment to change behavior. Additional support and advice should be provided and promoted for isolated people. Engaging in social networks from a remote location and maintaining a routine is likely to reduce the negative effects of isolation for wellness (Content et al., 2020).
Positive behavioral feedback involves interest in complying with regulatory measures in all three countries. In all three countries, acceptance of avoidance behavior, recommended behavior measures and information sufficiency was similar, and trust in government was similar in Singapore and Italy. Respondents in both Singapore and China were more willing to wear masks (Singapore 85.8%; China mean score 4.78 [range: 1‐5]) (Lim et al., 2020); as similar as these three countries Bangladeshi people have a higher level of trust in government.
Developing countries (e.g., Bangladesh) facing a variety of challenges to deploy these. It is almost difficult to change behaviors (Zhaia & Du, 2020). Over reactive behavior was common among the general public that can impede infection control (Dong & Bouey, 2020). As a Public Health Emergency a large population is either not aware or has no access to the information provided (Khan, et al., 2020). COVID-19 pandemic is fear. This can lead to individuals committing suicide (Cullen et al., 2020) although suicidal cases were happened in Bangladesh due to COVID-19. People with pre-existing (perceived danger, fear of virus transmission, social isolation, uncertainty, physical discomfort, and overwhelming negative news in mass media (D, et al., 2020) will be at increased risk of infection and negative physical effect with COVID-19. Serious mortality, rapid transmission and higher morbidity (Khan, et al., 2020) also increase this. The sudden increase in confirmed cases has brought tremendous anxiety and that can affect perception, behavior (PAKPOUR & GRIFFITHS, 2020). Anxiety is a state that results from an individual’s perception and behaviors to those stressors. Moreover anxiety may vary by gender, age. According to our study, there was a difference between genders in perception; females were more concerned about corona virus. Recommend behaviors conducting and awareness to improve self confidence (Xu et al., 2020) is important for this pandemic. The use of instant‐messaging technology and mobile phones, media has a negative effect, although government increases companying for control misinformation (Xu et al., 2020).These negative emotions can protect from disease but negative emotions can reduce the immune function and physiological mechanisms ( (Zhou et al., 2020). Social and cultural factors, immediacy, uncertainty, familiarity, personal control, scientific uncertainty, and trust in institutions and media all shape perception and response to risk messaging is one of the risk of COVID-19.Risk messaging can influence the ever-changing public behavior (Malecki et al., 2020)like maintaining hand hygiene and social distancing to prevent its spread. But in Bangladesh strictly adhere to the restrictions. Public adherence to government recommended protective behavior is crucial to the control of the spread of coronavirus (Duan et al., 2020). The psychological process may influence individual protective behavior, government intervention and perception, with the making trust to the adoption of protective behavior (Duan et al., 2020).
