An adaptive reduction algorithm for efficient chemical calculations in global atmospheric chemistry models
Santillana, Mauricio; Le Sager, Philippe; Jacob, Daniel James; Brenner, Michael P. (Elsevier BV, 2010)We present a computationally efficient adaptive method for calculating the time evolution of the concentrations of chemical species in global 3-D models of atmospheric chemistry. Our strategy consists of partitioning the ... -
COVID-19: US federal accountability for entry, spread, and inequities—lessons for the future
Hanage, William; Testa, Christian; Chen, Jarvis; Davis, Letitia; Pechter, Elise; Seminario, Peg; Santillana, Mauricio; Krieger, Nancy (Springer Science and Business Media LLC, 2020-11)The United States (US) has been among those nations most severely affected by the first—and subsequent—phases of the pandemic of COVID-19, the disease caused by SARS-CoV-2. With only 4% of the worldwide population, the US ... -
Effect of non-pharmaceutical interventions to contain COVID-19 in China
Lai, Shengjie; Ruktanonchai, Nick W; Zhou, Liangcai; Prosper, Olivia; Luo, Wei; Floyd, Jessica R; Wesolowski, Amy; Santillana, Mauricio; Zhang, Chi; Du, Xiangjun; Yu, Hongjie; Tatem, Andrew JOn March 11, 2020, the World Health Organization declared COVID-19 a pandemic1. The outbreak containment strategies in China based on non-pharmaceutical interventions (NPIs) appear to be effective2, but quantitative research ... -
Enhancing Situational Awareness to Prevent Infectious Disease Outbreaks from Becoming Catastrophic
Lipsitch, Marc; Santillana, Mauricio (Springer Berlin Heidelberg, 2019)Catastrophic epidemics, if they occur, will very likely start from localized and far smaller (noncatastrophic) outbreaks that grow into much greater threats. One key bulwark against this outcome is the ability of governments ... -
Estimating the Prevalence of COVID-19 in the United States: Three Complementary Approaches
Lu, Fred S.; Nguyen, Andrew; Link, Nick; Santillana, Mauricio (2020-04-18)Effectively designing and evaluating public health responses to the ongoing COVID-19 pandemic requires accurate estimation of the week to week burden of COVID-19. Unfortunately, a lack of systematic testing across the ... -
Evaluating the performance of infectious disease forecasts: A comparison of climate-driven and seasonal dengue forecasts for Mexico
Johansson, Michael A.; Reich, Nicholas G.; Hota, Aditi; Brownstein, John S.; Santillana, Mauricio (Nature Publishing Group, 2016)Dengue viruses, which infect millions of people per year worldwide, cause large epidemics that strain healthcare systems. Despite diverse efforts to develop forecasting tools including autoregressive time series, climate-driven ... -
Evaluation of Internet-Based Dengue Query Data: Google Dengue Trends
Gluskin, Rebecca Tave; Johansson, Michael A.; Santillana, Mauricio; Brownstein, John S. (Public Library of Science, 2014)Dengue is a common and growing problem worldwide, with an estimated 70–140 million cases per year. Traditional, healthcare-based, government-implemented dengue surveillance is resource intensive and slow. As global Internet ... -
The role of absolute humidity on transmission rates of the COVID-19 outbreak
Luo, Wei; Majumder, Maimuna; Liu, Dianbo; Poirier, Canelle; Mandl, Kenneth; Lipsitch, Marc; Santillana, Mauricio (2020-02-17)A novel coronavirus (COVID-19) was identified in Wuhan, Hubei Province, China, in December 2019 and has caused over 40,000 cases worldwide to date. Previous studies have supported an epidemiological hypothesis that cold ... -
Socioeconomic Status Determines COVID-19 Incidence and Related Mortality in Santiago, Chile
Mena, Gonzalo E.; Martinez Vargas, Pamela; Mahmud, Ayesha; Marquet, Pablo A.; Buckee, Caroline; Santillana, Mauricio (2021-01-15)The current coronavirus disease 2019 (COVID-19) pandemic has impacted dense urban populations particularly hard. Here, we provide an in-depth characterization of disease incidence and mortality patterns, and their dependence ... -
