Significance To contain the global spread of the 2019 novel coronavirus epidemic (COVID-19), border control measures, such as airport screening and travel restrictions, have been implemented in several countries. Our results show that these measures likely slowed the rate of exportation from mainland China to other countries, but are insufficient to contain the global spread of COVID-19. With most cases arriving during the asymptomatic incubation period, our results suggest that rapid contact… 

Figures and Tables from this paper

International travel-related control measures to contain the COVID-19 pandemic: a rapid review.
TLDR
There was very low-certainty evidence that cross-border travel controls can slow the spread of COVID-19, and concerns with the quality of modelling studies related to potentially inappropriate assumptions about the structure and input parameters, and an inadequate assessment of model uncertainty.
Travel-related control measures to contain the COVID-19 pandemic: a rapid review.
TLDR
The effectiveness of travel-related control measures during the COVID-19 pandemic on infectious disease and screening-related outcomes was assessed, and low-certainty evidence from modelling studies suggests a reduction in the number of imported or exported cases.
Effectiveness of quarantine measure on transmission dynamics of COVID-19 in Hong Kong
TLDR
A susceptible-exposed-infectious-quarantined-recovered (SEIQR) meta-population model is developed that can stratify the infections into imported and subsequent local infections, and suggests that the early quarantine for a suspected case before the symptom onset is a key factor to suppress COVID-19.
New Coronavirus (SARS-CoV-2) Crossing Borders Beyond Cities, Nations, and Continents: Impact of International Travel
TLDR
This article analyzes the spread of the novel coronavirus (SARS-CoV-2) along the routes of international travel, both by air and by sea and suggests measures that can be taken to reduce the risk of transmission associated with air travel.
Intercontinental transmission and local demographic expansion of SARS-CoV-2
TLDR
Analysis of global transmissions and potential demographic expansions of severe acute respiratory syndrome coronavirus 2 based on genomic information indicates that the travel restrictions and social distancing measures are effective in containing the spread of COVID-19.
SARS-CoV-2
TLDR
This work reconstructed global transmissions and potential demographic expansions of severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) based on genomic information and indicates that the travel restrictions and social distancing measures are effective in containing the spread of COVID-19.
Risk Assessment of Importation and Local Transmission of COVID-19 in South Korea: Statistical Modeling Approach
TLDR
The results indicated that the prompt implementation of airport screening measures (contact tracing with case isolation and quarantine) successfully reduced local transmission caused by imported cases despite passengers arriving from high-risk countries throughout the year.
Prevention and Control Measures for Imported SARS-CoV-2 Transmission During the Postpandemic Period in Shenzhen, China
TLDR
China’s experience with preventing and controlling COVID-19 in the postpandemic period is introduced, which may serve as a reference in various settings.
How US Travel Restrictions on China Affected the Spread of COVID-19 in the United States
TLDR
It is found that the travel restrictions did not delay the prevalence of COVID-19 or did so by 15 days at most and did not effect on the number of CO VID-19 cases in the United States.

The serial interval of COVID-19 from publicly reported confirmed cases
TLDR
Analysis of serial intervals of 468 infector-infectee pairs with confirmed COVID-19 cases reported by health departments in 18 Chinese provinces between January 21, 2020, and February 8, 2020 finds 12.6% of reports indicating pre-symptomatic transmission.
Experience of Severe Acute Respiratory Syndrome in Singapore: Importation of Cases, and Defense Strategies at the Airport
TLDR
The SARS outbreak in Singapore can be traced to the first imported case and the absence of transmission from the other imported cases was probably a result of relatively prompt identification and isolation of cases, together with a low potential for transmission.
Coronavirus Infections-More Than Just the Common Cold.
TLDR
Yet another pathogenic HCoV, 2019 novel coronavirus (2019-nCoV), was recognized in Wuhan, China, and has caused serious illness and death, and the ultimate scope and effect of this outbreak is unclear at present.
Epitope finding in 2019 novel coronavirus (2019-nCoV): The first world report
TLDR
The primary data on epitope finding in Wuhan novel coronavirus was reported and it was found that the peptide 929EDEE932 is the area with the highest epitope property (the highest value = 2.714).
Effectiveness of airport screening at detecting travellers infected with novel coronavirus (2019-nCoV)
TLDR
Airport screening is unlikely to detect a sufficient proportion of 2019-nCoV infected travellers to avoid entry of infected travellers, and sensitivity of exit and entry screening and proportion of asymptomatic cases are uncertain.
Spatial pattern of severe acute respiratory syndrome in-out flow in 2003 in Mainland China
TLDR
During 2002–2003, SARS in-out flow played an important role in countrywide transmission of the disease in Mainland China, and the flow had obvious spatial heterogeneity, which was influenced by migrants’ behavior characteristics.
Early Transmission Dynamics in Wuhan, China, of Novel Coronavirus–Infected Pneumonia
TLDR
This work aims to provide a systematic review and meta-analysis of the determinants of infectious disease-related deaths in children in the Hubei and Hebei regions over a 10-year period and aims to establish a smoking cessation strategy based on these findings.
Pneumonia of unknown aetiology in Wuhan, China: potential for international spread via commercial air travel
TLDR
The potential for international dissemination of this disease via commercial air travel should the outbreak of pneumonia of unknown aetiology in Wuhan, China continue is evaluated.
Pandemic influenza in Australia: Using telephone surveys to measure perceptions of threat and willingness to comply
TLDR
While only 14.9% of the state population thought pandemic influenza was very or extremely likely to occur, a significantly higher proportion were concerned for self and family should a pandemic actually occur.
Frequent Travelers and Rate of Spread of Epidemics
These travelers may increase spread of epidemics that have a long generation time, but have little effect on fast-spreading epidemics.
