“…Some studies have looked at the impact of international travel restrictions on the spread of COVID-19 globally. Most of these studies focused on the initial phase of the COVID-19 spread, when the epidemic was mainly concentrated in Wuhan, China; 6 , 7 , 8 , 9 these studies modelled the effect of flight restrictions from Wuhan or mainland China more generally. Chinazzi and colleagues 6 also used a dynamic metapopulation model to estimate the extent to which the restrictions might have delayed or prevented epidemics in target countries.…”

“…While other authors have evaluated the possible impacts that screening travellers solely upon arrival may have on reducing the risk of importing various diseases [7]- [9], less research has been conducted into the effects of enforcing a period of self-isolation. Of the work that has been done to-date, the majority focuses only on the effects of adopting a quarantine policy for the current COVID-19 outbreak [10], [11]. In this paper, we aim not only to build upon our previous work, but to also extend it as a general tool for other diseases and outbreak contexts.…”

“…on vacation), or more longer term (such as being a resident). Flight times are sampled from the ranges [3,5], [7,9] and [11,13] to model where travellers are required to take a short, medium or long-haul flight from country A to country B. Lastly, we consider quarantine periods which involves either 3, 5, 7, 10 or 14 days of self-isolation.…”

Investigating the potential benefit that requiring travellers to self-isolate on arrival may have upon the reducing of case importations during international outbreaks of influenza, SARS, Ebola virus disease and COVID-19

With the advent of rapid international travel, disease can now spread between nations faster than ever. As such, when outbreaks occur in foreign states, pressure mounts to reduce the risk of importing cases to the home nation. In a previous paper, we developed a model to investigate the potential effectiveness of deploying screening at airports during outbreaks of influenza, SARS, and Ebola. We also applied the model to the current COVID-19 outbreak. This model simulated the testing of travellers (assumed not to be displaying symptoms prior to boarding their flight) as they arrived at their destination. The model showed that the reduction in risk of case importation that screening alone could deliver was minimal across most scenarios considered, with outputs indicating that screening alone could detect at most 46.4%, 12.9%, and 4.0% of travellers infected with influenza, SARS and Ebola respectively, while the model also reported a detection rate of 12.0% for COVID-19. In this paper, we present a brief modification to this model allowing us to assess the added impact that quarantining incoming travelers for various periods may have on reducing the risk of case importation. Primary results show that requiring all travellers to undergo 5 days of self-isolation on arrival, after which they are tested again, has the potential to increase rates of detection to 100%, 87.6%, 81.7% and 41.3% for travellers infected with influenza, SARS, COVID-19 and Ebola respectively. Extending the period of self-isolation to 14 days increases these potential detection rates to 100%, 100%, 99.5% and 91.8% respectively.

“…A good example is the coronavirus disease 2019 (COVID-19), which is caused by severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) [ 5 ]. This novel coronavirus is genetically related to the Middle Eastern Respiratory Syndrome virus (MERS-CoV) and the Severe Acute Respiratory Syndrome virus (SARS-CoV) [ 6 ]. Coronavirus disease 2019 attacks not only the respiratory system but also other organs, such as the liver and the heart [ 7 , 8 ] and, due to its transmission directly or indirectly from one person to another, it is causing high mortality and morbidity rates [ 6 ].…”

Textiles functionalized with cupric oxide (CuO) nanoparticles have become a promising option to prevent the spread of diseases due to their antimicrobial properties, which strongly depend on the structure and morphology of the nanoparticles and the method used for the functionalization process. This article presents a review of work focused on textiles functionalized with CuO nanoparticles, which were classified into two groups, namely, in situ and ex situ. Moreover, the analyzed bacterial strains, the resistance of the antimicrobial properties of textiles to washing processes, and their cytotoxicity were identified. Finally, the possible antimicrobial mechanisms that could develop in Gram-positive and Gram-negative bacteria were described.
