Vaccination coverage and breakthrough infections of COVID-19 during the second wave among staff of selected medical institutions in India.

India experienced the second wave of SARS-CoV-2 infection from April 3 to June 10, 2021. During the second wave, Delta variant B.1617.2 emerged as the predominant strain, spiking cases from 12.5 million to 29.3 million (cumulative) by the end of the surge in India. Vaccines against COVID-19 are a potent tool to control and end the pandemic in addition to other control measures. India rolled out its vaccination programme on January 16, 2021, initially with two vaccines that were given emergency authorization-Covaxin (BBV152) and Covishield (ChAdOx1 nCoV- 19). Vaccination was initially started for the elderly (60+) and front-line workers and then gradually opened to different age groups. The second wave hit when vaccination was picking up pace in India. There were instances of vaccinated people (fully and partially) getting infected, and reinfections were also reported. We undertook a survey of staff (front line health care workers and supporting) of 15 medical colleges and research institutes across India to assess the vaccination coverage, incidence of breakthrough infections, and reinfections among them from June 2 to July 10, 2021. A total of 1876 staff participated, and 1484 forms were selected for analysis after removing duplicates and erroneous entries (n = 392). We found that among the respondents at the time of response, 17.6% were unvaccinated, 19.8% were partially vaccinated (received the first dose), and 62.5% were fully vaccinated (received both doses). Incidence of breakthrough infections was 8.7% among the 801 individuals (70/801) tested at least 14 days after the 2nd dose of vaccine. Eight participants reported reinfection in the overall infected group and reinfection incidence rate was 5.1%. Out of (N = 349) infected individuals 243 (69.6%) were unvaccinated and 106 (30.3%) were vaccinated. Our findings reveal the protective effect of vaccination and its role as an essential tool in the struggle against this pandemic.

Adherence to healthy behavioral practices promotes COVID 19 preventive behavior among chronic disease patients: A cross-sectional study from urban Rajasthan, India.

Background: The coronavirus disease-19 (COVID-19) pandemic has led to unprecedented morbidity and mortality across the world. Chronic disease patients of urban poor neighbourhoods are one of the most vulnerable population subgroups as the number of cases and deaths increase exponentially in India. The study aims to explore the factors associated with desirable health behaviours among chronic disease patients availing care from a primary health facility and examine their association with the COVID-19 preventive behaviour. Material and Methods: A cross-sectional study was conducted among chronic disease patients attending a health centre in an urban area of Jodhpur, Rajasthan. A interviewer administered semi-structured questionnaire was pilot tested and validated prior to initiation of data collection. A total of 520 patients were enrolled for the study. Results: Poor adherence to health behaviour was observed among a majority of the respondents (infrequent physical activity: 72.0%, one or less fruit serving per day: 96.5%, one or less vegetable serving per day: 88.8%). A factor analysis revealed three domains of COVID-19 preventive behaviour: sanitisation, preventive hygiene and social distancing. Multiple regression revealed respondents opting for COVID-19 screening and those with lower salt intake followed the overall and individual COVID-19 preventive behaviour. Conclusion: The health behaviour assessment and inter-personal counselling by the health care providers at the primary health facilities may contribute to the increasing adherence for the COVID-19 preventive behaviour among chronic disease patients.

Understanding the phases of vaccine hesitancy during the COVID-19 pandemic.

Vaccine hesitancy is an important feature of every vaccination and COVID-19 vaccination is not an exception. During the COVID-19 pandemic, vaccine hesitancy has exhibited different phases and has shown both temporal and spatial variation in these phases. This has likely arisen due to varied socio-behavioural characteristics of humans and their response towards COVID 19 pandemic and its vaccination strategies. This commentary highlights that there are multiple phases of vaccine hesitancy: Vaccine Eagerness, Vaccine Ignorance, Vaccine Resistance, Vaccine Confidence, Vaccine Complacency and Vaccine Apathy. Though the phases seem to be sequential, they may co-exist at the same time in different regions and at different times in the same region. This may be attributed to several factors influencing the phases of vaccine hesitancy. The complexities of the societal reactions need to be understood in full to be addressed better. There is a dire need of different strategies of communication to deal with the various nuances of all of the phases. To address of vaccine hesitancy, an understanding of the societal reactions leading to various phases of vaccine hesitancy is of utmost importance.

Identifying psychological antecedents and predictors of vaccine hesitancy through machine learning: A cross sectional study among chronic disease patients of deprived urban neighbourhood, India.

COVID-19 vaccine hesitancy among chronic disease patients can severely impact individual health with the potential to impede mass vaccination essential for containing the pandemic. The present study was done to assess the COVID-19 vaccine antecedents and its predictors among chronic disease patients. This cross-sectional study was conducted among chronic disease patients availing care from a primary health facility in urban Jodhpur, Rajasthan. Factor and reliability analysis was done for the vaccine hesitancy scale to validate the 5 C scale. Predictors assessed for vaccine hesitancy were modelled with help of machine learning (ML). Out of 520 patients, the majority of participants were female (54.81%). Exploratory factor analysis revealed four psychological antecedents' "calculation"; "confidence"; "constraint" and "collective responsibility" determining 72.9% of the cumulative variance of vaccine hesitancy scale. The trained ML algorithm yielded an R2 of 0.33. Higher scores for COVID-19 health literacy and preventive behaviour, along with family support, monthly income, past COVID-19 screening, adherence to medications and age were associated with lower vaccine hesitancy. Behaviour changes communication strategies targeting COVID-19 health literacy and preventive behaviour especially among population sub-groups with poor family support, low income, higher age groups and low adherence to medicines may prove instrumental in this regard.

Secondary prevention of silicosis and silico-tuberculosis by periodic screening of silica dust exposed workers using serum club cell protein 16 as a proxy marker.

BACKGROUND AND OBJECTIVES: Silicosis is a neglected and widely prevalent occupational disease in India and several other countries such as China, South Africa, Brazil, etc. It is an irreversible, incurable, and progressive disease with high morbidity and mortality, which is mostly caused by occupational exposure to silica dusts. Silicosis is usually detected at an advanced stage, when effective intervention is not possible. But early detection appears to be a cost-effective way to control it. There is a need for some suitable biomarker, which could detect silicosis at an early stage for further necessary intervention. This study aimed to estimate the lung damage in silicotic subjects and its relationship with serum CC16 as a proxy marker. The ultimate objective was to explore whether CC16 could be used as a screening tool for early detection of silicosis. METHODOLOGY: Radiographs of 117 workers having radiological evidences of silicosis were evaluated in accordance with International Labour Organisation (ILO) Classification of chest radiographs and were categorized as mild, moderate, and severe lung damage using a lung damage scoring system, made for the purpose of this study. The concentration of CC16 in serum was determined by enzyme-linked immunosorbent assay. RESULT: It was observed that serum CC16 values were significantly decreased in relation to increasing lung damage. The mean ± standard deviation (SD) serum CC16 value in mild lung damage group was 8.4 ± 0.87 ng/mL as compared to 4.0 ± 2.10 ng/mL in moderate and 0.7 ± 0.21 ng/mL in high lung damage groups. On the other hand, CC16 value of control (healthy) population was found to be 16.3 ± 3.8 ng/mL. CONCLUSION: Result of the study concluded that serum CC16 might be used as a periodic screening tool for early detection of silicosis and for it's secondary prevention. It may be viewed as a new approach toward control of silicosis, and an appropriate policy may be adopted.

Lifestyle and behavioral changes during nationwide lockdown in India-A cross-sectional analysis.

INTRODUCTION: After almost two months of reporting the first case of the novel coronavirus disease (COVID-19) in the country, the nationwide lockdown in India was initiated on 24th of March 2020, to curtail the spread of the SARS-CoV-2 infection in the country. While this lockdown had been in place for almost 3 months, the people of the nation have experienced changes in their routine lives in a wide range of activities, including personal behaviours. This study was conducted to identify the impacts that the lockdown had on the lifestyle and behavioural aspects of Indians during the lockdown. METHODS: It was a cross sectional study, conducted by online survey. Data collection was done for the period of 3 months. RESULTS: The study found that a huge number of participants had significant changes in their diet, sleep, bowel habits and also their personal traits. Also, the lockdown had improved interpersonal relationships and helped people explore their hobbies or even acquire a new skill (about 25% of the participants). More than 90% of the participants perceived decrease in air pollution and a majority reported increase in personal hygiene (74.2%), perceived decrease in crime rates (67.3%) as benefits of lockdown. CONCLUSIONS: It would be recommended to include variables to screen for mental health issues among the general population.

Enabling Readiness of a School to Reopen During a Pandemic - A Field Experience.

Modeling studies indicate that the closure of schools during the coronavirus disease (COVID-19) pandemic may not be well grounded for the severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) infection, as evidences indicate that children are less affected by this virus, and the clinical attack rates in the 0-19 age group are low. Experts also opine that school closures might have negative effects on the scholastic abilities of children and also an adverse impact on the economy and health care system, considering the responsibilities conferred upon the parents. Also, in a developing country like India, it is difficult for the rural population to afford distance online learning, which brings into importance the reopening of schools in a safe environment to avoid adversities such as increased drop-outs in the upcoming academic year, loss of in-person benefits such as mid-day meal scheme. This study highlights a field experience in relation to readiness assessment of a rural school in the Jodhpur district of Rajasthan, India, for a safe reopening to accept students in a safe and conducive atmosphere, which shall help prevent transmission of the virus in the schools among the children. In this regard, an indigenous readiness checklist has been developed to achieve the purpose, which assesses the readiness in 3 domains: (1) procedural readiness; (2) supplies, sanitation, and infrastructure-related; and (3) education and training.

COVID-19 vaccine hesitancy among medical students in India.

The coronavirus disease 2019 (COVID-19) vaccine was launched in India on 16 January 2021, prioritising health care workers which included medical students. We aimed to assess vaccine hesitancy and factors related to it among medical students in India. An online questionnaire was filled by 1068 medical students across 22 states and union territories of India from 2 February to 7 March 2021. Vaccine hesitancy was found among 10.6%. Concern regarding vaccine safety and efficacy, lack of awareness regarding their eligibility for vaccination and lack of trust in government agencies predicted COVID-19 vaccine hesitancy among medical students. On the other hand, the presence of risk perception regarding themselves being affected with COVID-19 reduced vaccine hesitancy as well as hesitancy in participating in COVID-19 vaccine trials. Vaccine-hesitant students were more likely to derive information from social media and less likely from teachers at their medical colleges. Choosing between the two available vaccines (Covishield and Covaxin) was considered important by medical students both for themselves and for their future patients. Covishield was preferred to Covaxin by students. Majority of those willing to take the COVID-19 vaccine felt that it was important for them to resume their clinical posting, face-to-face classes and get their personal life back on track. Around three-fourths medical students viewed that COVID-19 vaccine should be made mandatory for both health care workers and international travellers. Prior adult vaccination did not have an effect on COVID-19 vaccine hesitancy. Targeted awareness campaigns, regulatory oversight of vaccine trials and public release of safety and efficacy data and trust building activities could further reduce COVID-19 vaccine hesitancy among medical students.

Health literacy, preventive COVID 19 behaviour and adherence to chronic disease treatment during lockdown among patients registered at primary health facility in urban Jodhpur, Rajasthan.

BACKGROUND AND AIMS: Potential role of health literacy in determining adherence to COVID-19 preventive behavior, pharmacological, and lifestyle management among diagnosed patients of chronic diseases during nationwide lockdown is inadequately investigated. METHODS: A cross-sectional study was conducted from May-August 2020 among diagnosed patients of chronic diseases residing in a COVID-19 hotspot of urban Jodhpur, Rajasthan, and availing health services from primary care facility. Telephonic interviews of participants were conducted to determine their health literacy using HLS-EU-Q47 questionnaire, adherence to COVID-19 preventive behaviour as per World Health Organization recommendations, and compliance to prescribed pharmacological and physical activity recommendations for chronic disease. RESULTS: All the 605 diagnosed patients of chronic diseases availing services from primary care facility were contacted for the study, yielding response rate of 68% with 412 agreeing to participate. Insufficient health literacy was observed for 65.8% participants. Only about half of participants had scored above median for COVID-19 awareness (55.1%) and preventive behavior (45.1%). Health literacy was observed to be significant predictor of COVID-19 awareness [aOR: 3.53 (95% CI: 1.81-6.88)]; COVID-19 preventive behavior [aOR: 2.06, 95%CI; 1.14-3.69] and compliance to pharmacological management [aOR: 3.05; 95% CI: 1.47-6.35] but not for physical activity. CONCLUSION: COVID-19 awareness, preventive behavior, and compliance to pharmacological management is associated with health literacy among patients of chronic disease availing services from primary health facility. Focusing on health literacy could thus be an essential strategic intervention yielding long term benefits.
