Hygiene knowledge and practices and determinants of occupational safety among waste and sanitation workers in Bangladesh during the COVID-19 pandemic

Waste and sanitation workers provide essential services to society. In most low-and middle-income countries, they are often mistreated and lack access to necessary personal protective equipment (PPE) and hygiene facilities that ensure occupational safety in workplaces. COVID-19 has also imposed serious health risks upon these worker groups. This study explores factors associated with poor occupational health and safety based on a conceptual framework. We conducted 499 surveys with five categories of waste and sanitation workers across ten cities in Bangladesh. We performed descriptive analysis and used Firth's logistic regression model following the conceptual framework. The analysis revealed consistent distinctions between workers considered to be in “safe” versus “unsafe” working conditions. The result showed that workers had not been adequately trained, not provided with proper equipment, and many had an informal status that prevented access to hygiene facilities. The workers who received occupational training, knew how to prevent COVID-19 by wearing a face mask, hand washing, and maintaining social distance, maintained protective measures, and practiced proper disposing of PPEs were more likely to be in safe condition. Initiatives to improve the situation of the waste workers who work in unsafe work conditions are still inadequate. Therefore, we recommend supplying proper protective equipment, ensuring a regular supply of gender-specific PPEs, and providing functional facilities necessary to practice personal hygiene and occupational safety, such as handwashing stations, changing rooms, and disposal facilities of used PPEs at the workplace. We also urge increased institutional management procedures, infrastructure that facilitates hygiene practices, and social policies to reduce occupational hazards for the waste workers in Bangladesh during and beyond the COVID-19 pandemic.

Mobility Patterns During COVID-19 Travel Restrictions in Nairobi Urban Informal Settlements: Who Is Leaving Home and Why.

Nairobi's urban slums are ill equipped to prevent spread of the novel coronavirus disease (COVID-19) due to high population density, multigenerational families in poorly ventilated informal housing, and poor sanitation. Physical distancing policies, curfews, and a citywide lockdown were implemented in March and April 2020 resulting in sharp decreases in movement across the city. However, most people cannot afford to stay home completely (e.g., leaving daily to fetch water). If still employed, they may need to travel longer distances for work, potentially exposing them COVID-19 or contributing to its spread. We conducted a household survey across five urban slums to describe factors associated with mobility in the previous 24 h. A total of 1695 adults were interviewed, 63% female. Of these, most reported neighborhood mobility within their informal settlement (54%), 19% stayed home completely, and 27% reported long-distance mobility outside their informal settlement, mainly for work. In adjusted multinomial regression models, women were 58% more likely than men to stay home (relative risk ratio (RRR): 1.58, 95% confidence interval (CI): 1.16, 2.14) and women were 60% less likely than men to report citywide mobility (RRR: 0.40; 95% CI 0.31, 0.52). Individuals in the wealthiest quintile, particularly younger women, were most likely to not leave home at all. Those who reported citywide travel were less likely to have lost employment (RRR: 0.49; 95% CI 0.38, 0.65) and were less likely to avoid public transportation (RRR: 0.30; 95% CI 0.23, 0.39). Employment and job hunting were the main reasons for traveling outside of the slum; less than 20% report other reasons. Our findings suggest that slum residents who retain their employment are traveling larger distances across Nairobi, using public transportation, and are more likely to be male; this travel may put them at higher risk of COVID-19 infection but is necessary to maintain income. Steps to protect workers from COVID-19 both in the workplace and while in transit (including masks, hand sanitizer stations, and reduced capacity on public transportation) are critical as economic insecurity in the city increases due to COVID-19 mitigation measures. Workers must be able to commute and maintain employment to not be driven further into poverty. Additionally, to protect the majority of individuals who are only travelling locally within their settlement, mitigation measures such as making masks and handwashing stations accessible within informal settlements must also be implemented, with special attention to the burden placed on women.

Combating COVID-19 in Bangladesh: ideal duration of mandatory quarantine period and policy implications.

Amid this Covid-19 pandemic, it is crucial to have the best possible estimation for essential quarantine days to mitigate the risk of Coronavirus spread. In this article, we aim to better approximate the mandatory quarantine days based on the available published literature. Our review of scientific publications revealed that 14 days of quarantine is nor enough neither effective in restricting the Coronavirus. Instead of 14 days, one study suggested to imply 21 days of quarantine to completely assure the symptom appearance in infected people. In case of community transmission, as it might take up to 19.9 days to death from the first appearance of symptom in a community, an effective quarantine period to contain the spread of Coronavirus should be a minimum of 40 days. For a densely populated country like Bangladesh, planning effective strategies using available data is crucial to prevent the upcoming second wave of this pandemic.

COVID-19 related knowledge, attitudes, practices and needs of households in informal settlements in Nairobi, Kenya

Objective: Urban slums are at high risk of COVID-19 transmission due to the lack of basic housing, water, and sanitation, and overcrowding. No systematic surveys of slum households’ experiences exist to date. Methods: A mobile phone knowledge, attitudes, and practices survey was conducted March 30- 31, 2020. Participants were sampled from two study cohorts across five urban slums in Nairobi, Kenya. Findings: 2,009 individuals (63% female) participated. Knowledge of fever and cough as COVID-19 symptoms was high, but only 42% listed difficulty breathing. Most (83%) knew anyone could be infected;younger participants had lower perceived risk. High risk groups were correctly identified (the elderly - 64%;those with weak immune systems - 40%) however, 20% incorrectly stated children.Handwashing and using hand sanitizer were known prevention methods, though not having a personal water source (37%) and hand sanitizer being too expensive (53%) were barriers.Social distancing measures were challenging as 61% said this would risk income.A third worried about losing income, only 26% were concerned about infecting others if themselves sick. Government TV ads and short message service (SMS) were the most common sources of COVID-19 information and considered trustworthy (by >95%) but were less likely to reach less educated households. Conclusion: Knowledge of COVID-19 is high;significant challenges for behavior change campaigns to reach everyone with contextually appropriate guidance remain. Government communication channels should continue with additional efforts to reach less educated households.A strategy is necessary to facilitate social distancing, handwashing and targeted distributions of cash and food.
