“…The results from our main scenario accounting for imports suggest that the local 𝑅 𝑒 was below 1 and that imported cases led to a steady growth in the number of confirmed cases. Our study therefore supports the notion that travelers play an important role in the spread of SARS-CoV-2 (Worobey et al, 2020;Hodcroft et al, 2021;Shearer et al, 2022), and provides further evidence that the contribution of imported cases on the local epidemic dynamics depends on the local incidence (Russell et al, 2021;Lemey et al, 2021). Furthermore, the risk of getting infected with SARS-CoV-2 while abroad can differ from the risk at home due to differences in incidence and behavior.…”

“…The genetically homogenous grouping could represent a point-source outbreak or multiple introductions of genetically-similar viruses, as has previously been observed in university-based influenza surveillance [30]. Reduced transmission during the summer, competition with the first Omicron epidemic and ongoing adherence with NPIs as well as incomplete sampling, and stochastic transmission variability, may all account for the limited observed onward transmission of some viruses [31].…”

Background: COVID-19 pandemic mitigation measures, including travel restrictions, effectively limited global circulation of influenza viruses. In Australia, travel bans for non-residents and quarantine requirements for returned travellers were eased in November 2021, providing pathways for influenza viruses to be re-introduced. Methods: From 1 November 2021 to 30 April 2022 we conducted an epidemiological study to investigate the re-establishment of influenza in Victoria, Australia. We analyzed case notification data from the Victorian Department of Health to describe case demographics, interviewed the first 200 cases to establish probable routes of virus reintroduction, and examined phylogenetic and antigenic data to understand virus diversity and susceptibility to current vaccines. Results: Overall, 1598 notifications and 1064 positive specimens were analyzed. The majority of cases occurred in the 15-34 year age group. Case interviews revealed a higher incidence of international travel exposure during the first month of case detections and high levels of transmission in university residential colleges associated with the return to campus. Influenza A(H3N2) was the dominant subtype, with a single lineage predominating despite multiple importations. Conclusions: Enhanced testing for respiratory viruses during the COVID-19 pandemic provided a more complete picture of influenza virus transmission compared to previous seasons. Returned international travellers were important drivers of the re-emergence of influenza, as were young adults, a group whose role has previously been under-recognised in the establishment of seasonal influenza epidemics. Targeting interventions, including vaccination, to these groups could reduce influenza transmission in the future.

“…During the early stages of the COVID-19 outbreak, governments were required to make critical decisions on how to respond, despite limited data being available [ 32 ]. In this situation full of uncertainties, maximizing the use of limited medical resources is the priority principle of planning prevention strategies.…”

The demand for mobile epidemic prevention medical stations originated from the rapid spread of the COVID-19 pandemic. In order to reduce the infection risk of medical practitioners and provide flexible medical facilities in response to the variable needs of the pandemic, this research aimed to design mobile medical stations for COVID-19 epidemic prevention, the emergence of which began in February 2020. The mobile medical stations include a negative pressure isolation ward, a positive pressure swabbing station, a fever clinic and a laboratory. In Taiwan, many medical institutions used the mobile swabbing station design of this study to practice COVID-19 screening pre-tests. Internationally, this study assisted Palau in setting up medical stations to provide anti-epidemic goods and materials. The design of this study not only provides a highly flexible and safe medical environment but the benefits of screening can also be used as resources for medical research, forming an economic circulation for operation sustainability. In addition, the design of this study can also be used during the non-epidemic period as a healthcare station for rural areas or as a long-term community medical station.
