Mobility network models of COVID-19 explain inequities and inform reopening.

The coronavirus disease 2019 (COVID-19) pandemic markedly changed human mobility patterns, necessitating epidemiological models that can capture the effects of these changes in mobility on the spread of severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2)1. Here we introduce a metapopulation susceptible-exposed-infectious-removed (SEIR) model that integrates fine-grained, dynamic mobility networks to simulate the spread of SARS-CoV-2 in ten of the largest US metropolitan areas. Our mobility networks are derived from mobile phone data and map the hourly movements of 98 million people from neighbourhoods (or census block groups) to points of interest such as restaurants and religious establishments, connecting 56,945 census block groups to 552,758 points of interest with 5.4 billion hourly edges. We show that by integrating these networks, a relatively simple SEIR model can accurately fit the real case trajectory, despite substantial changes in the behaviour of the population over time. Our model predicts that a small minority of 'superspreader' points of interest account for a large majority of the infections, and that restricting the maximum occupancy at each point of interest is more effective than uniformly reducing mobility. Our model also correctly predicts higher infection rates among disadvantaged racial and socioeconomic groups2-8 solely as the result of differences in mobility: we find that disadvantaged groups have not been able to reduce their mobility as sharply, and that the points of interest that they visit are more crowded and are therefore associated with higher risk. By capturing who is infected at which locations, our model supports detailed analyses that can inform more-effective and equitable policy responses to COVID-19.

Cost Comparison Between 2 Responses to Hepatitis A Virus Incidents in Restaurant Food Handlers-New York City, 2015 and 2017.

CONTEXT: While the New York City Department of Health and Mental Hygiene (DOHMH) can use agency-wide emergency activation to respond to a hepatitis A virus-infected food handler, there is a need to identify alternative responses that conserve scarce resources. OBJECTIVE: To compare the costs incurred by DOHMH of responding to a hepatitis A case in restaurant food handlers using an agency-wide emergency activation (2015) versus the cost of collaborating with a private network of urgent care clinics (2017). DESIGN: We partially evaluate the costs incurred by DOHMH of responding to a hepatitis A case in a restaurant food handler using agency-wide emergency activation (2015) with the cost of collaborating with a private network of urgent care clinics (2017) estimated for a scenario in which DOHMH incurred the retail cost of services rendered. RESULTS: Costs incurred by DOHMH for emergency activation were $65 831 ($238 per restaurant employee evaluated) of which DOHMH personnel services accounted for 85% ($55 854). Costs of collaboration would have totaled $50 914 ($253 per restaurant employee evaluated) of which personnel services accounted for 6% ($3146). CONCLUSIONS: Accounting for incident size, collaborating with the clinic network was more expensive than agency-wide emergency activation, though required fewer DOHMH personnel services.

Educating Restaurant Workers About Paid Sick Leave: A Pilot Study From New York City.

Across the United States, cities, states, and counties are rapidly adopting paid sick leave laws. Paid sick leave policies for restaurant workers may be particularly beneficial, since these workers are less likely to have these benefits and have the potential to spread infection through food-handling and engagement with the public. In order for paid sick leave laws to work, workers and employers must be educated about these laws broadly and effectively. Focusing on New York City, we conducted a pilot research using key stakeholder interviews to learn about New York City's successes and challenges in educating workers and businesses about the law. Our findings indicate several lessons learned, including allocating sufficient funding, combined use of coalition building and organizing models, and attention to the needs of immigrant restaurant workers. Findings also suggest that greater attention should be paid to proactively addressing workplace organization and practices that thwart paid sick leave use.

Smokefree implementation in Colombia: Monitoring, outside funding, and business support.

OBJECTIVE:: To analyze successful national smokefree policy implementation in Colombia, a middle income country. MATERIALS AND METHODS:: Key informants at the national and local levels were interviewed and news sources and government ministry resolutions were reviewed. RESULTS:: Colombia's Ministry of Health coordinated local implementation practices, which were strongest in larger cities with supportive leadership. Nongovernmental organizations provided technical assistance and highlighted noncompliance. Organizations outside Colombia funded some of these efforts. The bar owners' association provided concerted education campaigns. Tobacco interests did not openly challenge implementation. CONCLUSIONS:: Health organization monitoring, external funding, and hospitality industry support contributed to effective implementation, and could be cultivated in other low and middle income countries.

Resumen: Objetivo: Analizar la implementación exitosa de políticas nacionales de ambientes libres de humo en Colombia, un país de ingresos medios. Material y métodos: Entrevistas con informantes claves a nivel nacional y local, y revisión de artículos en las noticias y resoluciones ministeriales nacionales. Resultados: El Ministerio de Salud de Colombia coordinó las prácticas locales para la implementación, que fueron más fuertes en las ciudades grandes y en las ciudades con líderes políticos que la apoyaron. Organizaciones no gubernamentales proporcionaron asistencia técnica y destacaron el incumplimiento. Organizaciones fuera de Colombia financiaron algunos de estos esfuerzos. La asociación de propietarios de bares proporcionó campañas de educación concertadas. Intereses tabacaleros no desafiaron abiertamente la implementación. Conclusiones. La vigilancia de las organizaciones no gubernamentales, la financiación externa y el apoyo de la industria de la hospitalidad contribuyeron a una implementación eficaz. Tales factores pueden ser cultivados en países de ingresos bajos y medios.

Multi-strategic intervention to enhance implementation of healthy canteen policy: a randomised controlled trial.

BACKGROUND: Internationally, governments have implemented school-based nutrition policies to restrict the availability of unhealthy foods from sale. The aim of the trial was to assess the effectiveness of a multi-strategic intervention to increase implementation of a state-wide healthy canteen policy. The impact of the intervention on the energy, total fat, and sodium of children's canteen purchases and on schools' canteen revenue was also assessed. METHODS: Australian primary schools with a canteen were randomised to receive a 12-14-month, multi-strategic intervention or to a no intervention control group. The intervention sought to increase implementation of a state-wide healthy canteen policy which required schools to remove unhealthy items (classified as 'red' or 'banned') from regular sale and encouraged schools to 'fill the menu' with healthy items (classified as 'green'). The intervention strategies included allocation of a support officer to assist with policy implementation, engagement of school principals and parent committees, consensus processes with canteen managers, training, provision of tools and resources, academic detailing, performance feedback, recognition and marketing initiatives. Data were collected at baseline (April to September, 2013) and at completion of the implementation period (November, 2014 to April, 2015). RESULTS: Seventy schools participated in the trial. Relative to control, at follow-up, intervention schools were significantly more likely to have menus without 'red' or 'banned' items (RR = 21.11; 95% CI 3.30 to 147.28; p ≤ 0.01) and to have at least 50% of menu items classified as 'green' (RR = 3.06; 95% CI 1.64 to 5.68; p ≤ 0.01). At follow-up, student purchases from intervention school canteens were significantly lower in total fat (difference = -1.51 g; 95% CI -2.84 to -0.18; p = 0.028) compared to controls, but not in energy (difference = -132.32 kJ; 95% CI -280.99 to 16.34; p = 0.080) or sodium (difference = -46.81 mg; 95% CI -96.97 to 3.35; p = 0.067). Canteen revenue did not differ significantly between groups. CONCLUSION: Poor implementation of evidence-based school nutrition policies is a problem experienced by governments internationally, and one with significant implications for public health. The study makes an important contribution to the limited experimental evidence regarding strategies to improve implementation of school nutrition policies and suggests that, with multi-strategic support, implementation of healthy canteen policies can be achieved in most schools.

Media Outlet and Consumer Reactions to Promotional Activities of the Choose Health LA Restaurants Program in Los Angeles County.

OBJECTIVE: This study sought to assess promotional activities undertaken to raise public awareness of the Choose Health LA Restaurants program in Los Angeles County, an environmental change strategy that recognizes restaurants for offering reduced-size and healthier menu options. DESIGN: We used multiple methods to assess public awareness of and reactions to the promotional activities, including an assessment of the reach of core promotional activities, a content analysis of earned media, and an Internet panel survey. SETTING: The study was conducted in Los Angeles County, home to more than 10 million residents. PARTICIPANTS: An online survey firm recruited participants for an Internet panel survey; to facilitate generalization of results to the county's population, statistical weights were applied to analyses of the survey data. INTERVENTION: Promotional activities to raise awareness of the program included community engagement, in-store promotion, and a media campaign. MAIN OUTCOME MEASURES: Outcomes included media impressions, the number of people who reported seeing the Choose Health LA Restaurants logo, and a description of the themes present in earned media. RESULTS: Collectively, paid media outlets reported 335 587 229 total impressions. The Internet panel survey showed that 12% of people reported seeing the program logo. Common themes in earned media included the Choose Health LA Restaurants program aims to provide restaurant patrons with more choices, represents a new opportunity for restaurants and public health to work together, will benefit participating restaurants, and will positively impact health. CONCLUSIONS: Promotional activities for the Choose Health LA Restaurants program achieved modest reach and positive reactions from media outlets and consumers. The program strategy and lessons learned can help inform present and future efforts to combine environmental and individually focused strategies that target key influences of consumer food selection.
