Introduction: Countries globally are evaluating the concept of herd immunity and its critical role in the control of pandemic. The current paper attempts to conduct a critical interpretative synthesis (CIS) on the role of herd immunity in current COVID‑19 pandemic. Methods: CIS is tool for developing theoretical framework using interpretation drawn from relevant empirical and non‑empirical sources. This review is done by formulating review question for literature search. Purposive sampling of literature was done followed by reciprocal translational analysis of extracted data. Results: Herd immunity is indirect protection from a contagious infectious disease when a population is immune either through vaccination or natural immunity developed through previous infection. The reproduction number for COVID‑19 in India was found to be 2.56 and herd immunity threshold as 61%. Discussion: Exposing 71% young population in India to the SARS‑CoV‑2 infection can achieve herd immunity but with high morbidity as well as mortality. Vaccine are under process. Feco‑oral transmission and reinfection of COVID 19 are major factors to develop or break the circle of herd immunity in community. “Immunity passport” can give false sense of security. Surveillance and seroprevalence studies assess immunity status, gradual exposure of infection to younger population and collaborative partnerships on organizations are few strategies to acquire herd immunity. Conclusion: Herd immunity is a measure for prevention and control of COVID‑19 pandemic against the backdrop of mortality and morbidity. Vaccine can be boon but if herd immunity is to be acquired by natural infection then preparedness is necessary. [ABSTRACT FROM AUTHOR]

Difficulties of the hearing impaired have increased due to COVID-19, leading to lack of inclusiveness along with the breakdown of their mental, physical, and social health. The study objective was to assess the challenges faced by the deaf and hearing-impaired people during COVID-19 by a literature review. Literature search was done using keywords such as "challenges" OR "barriers" and "COVID-19" OR "Deaf" OR "Hearing Impaired" OR "Communication" on PubMed and Google Scholar from November 2019 to June 2020. The challenges faced were lack of information, face mask making communication difficult, social distancing affecting their physical, mental health, stigma and barriers related to the health-care system. Strategies included use of technology, help from sign language instructors, and preparedness of health-care settings for the hearing disabled. System strengthening, tele-medicine, and policy amendments can be the pillars to build up the support system for the hearing impaired to protect them from COVID-19. [ABSTRACT FROM AUTHOR]

One of the major steps to prevent damage due to any pandemic is to focus on risk factors related to the disease. Tobacco consumption is emerging as a major factor out of all for COVID 19. There is hardly any country who has warned the public about this or has made the Tobacco control measures stringent in view of COVID 19. Factors making tobacco consumers more vulnerable to COVID 19 infections are low immunity, damaged cilia in smaller air ways leading to decreased lung capacity and previous history of respiratory illness. Smokers have more expression of ACE2 receptor gene which is also responsible for SARS-COV-2 virus replication in host. More viral load makes smokers potent "carrier". COVID 19 can be transmitted via tobacco consumers by sharing of smoked tobacco and release of vapour droplets. Spitting of smokeless tobacco in public places puts community at risk. Cardiovascular diseases and cancers caused by tobacco consumption act as comorbidities aggravating the symptoms in COVID 19 infection. Scope of FCTC framework can be extended to address prevention and control of COVID 19. Recommendations: tobacco products should be banned immediately to control the spread. MPOWER strategy of FCTC can be utilized in this pandemic to prevent transmission. [ABSTRACT FROM AUTHOR]

Most of the world's 300 million smokeless tobacco (ST) users live in South Asia but ST policies for that region are poorly researched, developed and implemented. Longitudinal studies to understand the uptake and use of ST and smoking, and influences on these, such as health promotion strategies, are lacking. We planned to conduct longitudinal surveys among secondary school students in three countries with the highest ST burden: Bangladesh, India and Pakistan to explore ST and smoking uptake, use and health promoting strategies. Before running that longitudinal study, we assessed the feasibility of conducting such a multi country survey using a mixed-methods design. The survey (and feasibility study) was conducted in 24 secondary schools (eight per country, three classes per school). Three data sources, researcher records/fieldnotes, survey data of 1179 students, and interview/focus group discussion data from 24 headteachers, 64 teachers and 76 students, were used to understand the feasibility of three study tasks: 1) selecting, recruiting, and retaining schools and student participants; 2) survey administration; and 3) robustness of the data collection instruments. The datasets were analysed separately and triangulated. Overall, we could select and recruit schools and students using consistent methods across countries although recruitment was challenged by securing higher authority permissions and parental consent. Recommended improvements were for permission/consent processes. Survey administration was generally feasible and acceptable with recommendations for scheduling and researcher-student ratios. Questionnaire completion was 83%-100% across countries, with suggestions to improve readability and understanding, addressing students' queries and questionnaire simplification. Due to COVID-19, we could not conduct follow-up surveys, so were unable to assess school or student retention. In conclusion, incorporating the lessons learnt from this study would improve the feasibility of conducting such a multi-country survey in the future. Reported benefits included increasing tobacco health risks' knowledge with potential for increased tobacco control support., Competing Interests: The authors have declared that no competing interests exist., (Copyright: © 2024 Mishu et al.

Background: Smokeless tobacco (ST) use is common among youth in South Asia where 85% of the world's 300 million ST users live and use the most lethal ST forms. Little is known about the impact of tobacco control policies on the youth ST uptake in those countries. We planned to conduct longitudinal surveys among school going adolescents to evaluate existing tobacco control policies on tobacco uptake and use, and a feasibility study for that prospective, observational cohort study. Study objectives: (1) To demonstrate the feasibility of selection, recruitment and retention of schools and of study participants; (2) To assess the feasibility and acceptability of the study procedure and study tool (questionnaire); (3) To evaluate if the questionnaire can assess tobacco uptake and use, and their potential predictors. Methods and analysis: The feasibility study will be conducted in two administrative areas within each of three South Asian countries: Bangladesh, India and Pakistan. We will use both quantitative and qualitative data collection methods. Eight eligible schools will be randomly selected within purposively selected sub-districts from each country. We plan to conduct one baseline and one follow up survey among students of grade 6-8, one year apart. At each time point, data on tobacco uptake and potential predictors will be collected from students via self-administered questionnaires that were designed for the longitudinal study. The qualitative component will be embedded into the study with each round of data collection to assess the acceptability of the study instrument (questionnaire) and data collection methods, via focus group discussions with students and semi-structured interviews with schoolteachers. Recruitment and retention rates, completeness of the questionnaires, frequencies and associations of tobacco use and explanatory variables will be reported. Data gathered from the focus group and interviews will be analysed using the framework approach., Competing Interests: No competing interests were disclosed., (Copyright: © 2022 Mishu MP et al.)
