Governments around the world are responding to the novel coronavirus (COVID-19) pandemic 1 with unprecedented policies designed to slow the growth rate of infections. Many actions, such as closing schools and restricting populations to their homes, impose large and visible costs on society, but their benefits cannot be directly observed and are currently understood only through process-based simulations 2–4 . Here, we compile new data on 1,717 local, regional, and national non-pharmaceutical… 
Effects of government policies on the spread of COVID-19 worldwide
Wave-specific analysis for each wave showed that significant health, economic, and containment policies varied across waves of the pandemic, while emergency investment in healthcare was consistently significant among the three groups of countries, while the Stringency index was significant among all waves ofThe pandemic.
COVID-19 anti-contagion policies and economic support measures in the USA
Current literature assumes that non-pharmaceutical interventions (NPIs) reduce COVID-19 infections uniformly, that is, irrespectively of their strength. The role of economic support measures (ESM)
The effects of COVID ‐19 containment measures on the Asia‐Pacific region
Abstract As the COVID-19 pandemic spread across the world, governments introduced significant containment measures to control the spread of the virus. In this paper, we leverage inputs from IMF desk
Estimating the effects of non-pharmaceutical interventions on the number of new infections with COVID-19 during the first epidemic wave
Among the NPIs considered, event bans were most effective, followed by venue and school closures, whereas stay-at-home orders and work bans were least effective.
The Economics of the COVID-19 Pandemic in Poor Countries
The rapidly expanding body of empirical research that documents its many adverse economic and non-economic effects in terms of living standards, education, health, and gender equality is surveyed, which appear to be unprecedented in depth and scale.
Short- and medium-term impacts of strict anti-contagion policies on non-COVID-19 mortality in China
China’s strict anti-contagion policies during the CO VID-19 pandemic significantly reduced non-COVID-19 mortality outside Wuhan (by 4.6%) and the health benefits persisted and became even greater after the measures were loosened: mortality was reduced by 12.5% in the medium term.
An epidemic model for SARS-CoV-2 with self-adaptive containment measures.
An epidemiological model is developed that embeds an algorithm mimicking the self-adaptive policy mechanism effective in Italy between November 2020 and March 2022 to show how the policy framework may affect the trade-off between health outcomes and the restrictiveness of mitigation measures.
A control framework to optimize public health policies in the course of the COVID-19 pandemic
It is shown the importance of finely tuning the levels of enforced measures to achieve SARS-CoV-2 containment, with periodic interventions emerging as an optimal control strategy in the long-term.


Differential effects of intervention timing on COVID-19 spread in the United States
It is found that marked, asynchronous reductions of the basic reproductive number occurred throughout the United States in association with social distancing and other control measures, and counterfactual simulations indicate that, had these same measures been implemented 1 to 2 weeks earlier, substantial cases and deaths could have been averted.
Effective containment explains subexponential growth in recent confirmed COVID-19 cases in China
A parsimonious model is introduced that captures both quarantine of symptomatic infected individuals, as well as population-wide isolation practices in response to containment policies or behavioral changes, and shows that the model captures the observed growth behavior accurately.
Dynamics of COVID-19 under social distancing measures are driven by transmission network structure
It is found that the strength of within-household transmission is a critical determinant of success, governing the timing and size of the epidemic peak, the rate of decline, individual risks of infection, and the success of partial relaxation measures.
An investigation of transmission control measures during the first 50 days of the COVID-19 epidemic in China
The national emergency response appears to have delayed the growth and limited the size of the COVID-19 epidemic in China, averting hundreds of thousands of cases by 19 February (day 50), and suspending intracity public transport, closing entertainment venues, and banning public gatherings were associated with reductions in case incidence.
Effective containment explains sub-exponential growth in confirmed cases of recent COVID-19 outbreak in Mainland China
A parsimonious model is introduced that captures both, quarantine of symptomatic infected individuals as well as population wide isolation in response to mitigation policies or behavioral changes, and implies that the observed scaling law in confirmed cases is a direct signature of effective contaiment strategies and/or systematic behavioral changes that affect a substantial fraction of the susceptible population.
Substantial undocumented infection facilitates the rapid dissemination of novel coronavirus (SARS-CoV-2)
It is estimated that 86% of all infections were undocumented before the 23 January 2020 travel restrictions, which explains the rapid geographic spread of SARS-CoV-2 and indicates that containment of this virus will be particularly challenging.
The effect of travel restrictions on the spread of the 2019 novel coronavirus (COVID-19) outbreak
The results suggest that early detection, hand washing, self-isolation, and household quarantine will likely be more effective than travel restrictions at mitigating this pandemic, and sustained 90% travel restrictions to and from mainland China only modestly affect the epidemic trajectory unless combined with a 50% or higher reduction of transmission in the community.
Pros and cons of estimating the reproduction number from early epidemic growth rate of influenza A (H1N1) 2009
An updated estimate of R is provided that takes into account the epidemic data from 29 May to 14 July, and the next-generation matrix predicts that only 17.5% of the population will experience infection by the end of the first pandemic wave.
Public health interventions and epidemic intensity during the 1918 influenza pandemic
The hypothesis that rapid implementation of multiple NPIs can significantly reduce influenza transmission, but that viral spread will be renewed upon relaxation of such measures is supported.
The effect of human mobility and control measures on the COVID-19 epidemic in China
Real-time mobility data from Wuhan and detailed case data including travel history are used to elucidate the role of case importation in transmission in cities across China and to ascertain the impact of control measures.
