Pilot of a Low-Cost Elementary School Handwashing Intervention in Bangladesh: Acceptability, Feasibility, and Potential for Sustainability.

Schoolchildren frequently transmit respiratory and gastrointestinal infections because of dense person-to-person contact in schools. We piloted a low-cost handwashing intervention among elementary schoolchildren in Bangladesh. We trained teachers to lead behavior change communication sessions using flipcharts to encourage students' handwashing before eating, after defecating, and after cleaning school toilets; provided handwashing stations (reservoirs with taps and stool + basin + soapy water solution [mix of 30 gm detergent with 1.5 L water] + pump top bottle with steel holder); and formed hygiene committees for maintenance and covering the recurrent cost of detergent. We evaluated intervention acceptability, feasibility, and potential for sustainability at 1 and 14 months after the intervention. At baseline, of 300 before eating events, no one washed hands with soap, and 99.7% (299) did not wash hands at all as soap was unavailable. Out of 269 after toileting events, 0.7% (2) washed hands with soap, and 88% (237) did not wash hands. After 4 weeks of the intervention, 45% (87/195 before eating events), 83% (155/186 after toileting events), and 100% (15/15 after cleaning toilet events) washed both hands with soapy water as children found it accessible, low cost, and child friendly. After 14 months, 9.4% (55/586 before eating events) and 37% (172/465 after toileting events) washed both hands with soapy water for health benefits. The intervention was acceptable and feasible; it overcame limited access to soap and water and was affordable as schools covered the recurrent costs of detergent. Further research should explore long-term habit adoption and impact on health and attendance.

COVID-19 vaccine rumors and conspiracy theories: The need for cognitive inoculation against misinformation to improve vaccine adherence.

INTRODUCTION: Rumors and conspiracy theories, can contribute to vaccine hesitancy. Monitoring online data related to COVID-19 vaccine candidates can track vaccine misinformation in real-time and assist in negating its impact. This study aimed to examine COVID-19 vaccine rumors and conspiracy theories circulating on online platforms, understand their context, and then review interventions to manage this misinformation and increase vaccine acceptance. METHOD: In June 2020, a multi-disciplinary team was formed to review and collect online rumors and conspiracy theories between 31 December 2019-30 November 2020. Sources included Google, Google Fact Check, Facebook, YouTube, Twitter, fact-checking agency websites, and television and newspaper websites. Quantitative data were extracted, entered in an Excel spreadsheet, and analyzed descriptively using the statistical package R version 4.0.3. We conducted a content analysis of the qualitative information from news articles, online reports and blogs and compared with findings from quantitative data. Based on the fact-checking agency ratings, information was categorized as true, false, misleading, or exaggerated. RESULTS: We identified 637 COVID-19 vaccine-related items: 91% were rumors and 9% were conspiracy theories from 52 countries. Of the 578 rumors, 36% were related to vaccine development, availability, and access, 20% related to morbidity and mortality, 8% to safety, efficacy, and acceptance, and the rest were other categories. Of the 637 items, 5% (30/) were true, 83% (528/637) were false, 10% (66/637) were misleading, and 2% (13/637) were exaggerated. CONCLUSIONS: Rumors and conspiracy theories may lead to mistrust contributing to vaccine hesitancy. Tracking COVID-19 vaccine misinformation in real-time and engaging with social media to disseminate correct information could help safeguard the public against misinformation.

Pilot of an Elementary School Cough Etiquette Intervention: Acceptability, Feasibility, and Potential for Sustainability.

Schools convene many people together for a prolonged time, facilitating spread of respiratory pathogens and amplifying epidemics. Crowded Bangladeshi schools lack the infrastructure to support optimal cough etiquette behaviors. We collected formative data on current practices from four elementary schools, and developed and piloted a low-cost cough etiquette intervention, promoting coughing and sneezing into upper sleeves at four additional schools. We trained teachers to lead behavior change sessions during regular hygiene classes for 4 weeks. We evaluated intervention acceptability, feasibility, and potential for sustainability at 1 month and at 14 months after the intervention commenced. At baseline, among 63 observed students, 58 (92%) coughed/sneezed into open air, five (8%) covered coughs/sneezes with their hands, which were not subsequently washed with soap and water as they judged this infeasible. After 4 weeks, among 70 observed students, 27 (39%) coughed/sneezed into upper sleeves, 33 (47%) into open air, and 10 (12%) covered with hands. After 14 months, among 230 observed students, 13 (6%) used upper sleeves, 154 (67%) coughed/sneezed into open air, and 59 (26%) covered with hands. Students reported that coughing/sneezing into upper sleeves was simple and protected them and their classmates from germs. This school-based intervention was acceptable and feasible, and resulted in short-term reductions in coughing/sneezing into open air, but these habits of comparatively new behavior were not sustained as teachers ceased behavior change session delivery. Strategies to support longer-term adoption of habits should be considered.
