“…Third, there is no change immediately after the spike in terms of public transport closure x6 (Figure 2e), contact-tracing policy x14 (Figure 2h), income support x10, and debt relief x11 (Figure 2g). It means that Taiwan seems to view that these strategies are still effective in combatting the pandemic [44][45][46][47][48][49][50][51].…”

Covid-19 pandemic badly affects most countries in the world both sociologically and economically. Taiwan, however, manages to handle its pandemic remarkably well before and after its Covid-19 cases spike. This paper aims to describe Taiwan’s strategy on keeping the cases low and to identify significant factors related to this spike. These factors are found through the use of a stepwise regression model. The model inputs are daily data sets that belong to the three grouped indicators: Containment and closures, Economic responses and Health systems. In addition, the number of Covid-19 tests and changes in the number of people attending indoor and outdoor activities are also given as model inputs. The model output is the daily covid-19 confirmed cases. It is found that restriction in internal move, government campaign, debt or contract relieved, indoor activities changes, work closures and their interactions are amongst the most significant factors leading to the sharp jump in Covid-19 cases. The model is able to explain almost 88% of the cases. It is important that these factors are taken into consideration by any government in its preparation for an upcoming pandemic.

“…Contact tracing has long been a key public health tool for slowing or stopping the spread of infectious diseases [ 1 ]. It allows rapid and accurate identification of individuals who have been exposed to confirmed or probable cases (contacts) and, thus, the infection’s chain of transmission to be broken [ 2 ].…”

The adoption of digital contact-tracing apps to limit the spread of SARS-CoV-2 has been sup-optimal, but studies that clearly identify factors associated with the app uptake are still limited. In April 2021, we administered a questionnaire to healthcare university students to investigate their attitudes towards and experiences of the IMMUNI app. A multivariable logistic regression model was built to identify app download predictors. Adjusted odds ratios (aORs) and 95% confidence intervals (CIs) were calculated. We surveyed 247 students. Most respondents (65.6%) had not downloaded IMMUNI, reporting as the main reason the perceived app uselessness (32.7%). In the multivariable analysis, being advised to use the app (aOR: 3.21, 95%CI: 1.80–5.73), greater fear of infecting others (aOR: 1.50, 95%CI: 1.01–2.23), and greater trust in the institutional response to the emergency (aOR: 1.33, 95%CI: 1.00–1.76) were positively associated with the outcome, whereas greater belief in the “lab-leak theory” of COVID-19 was a negative predictor (aOR: 0.75, 95%CI: 0.60–0.93). Major technical issues were reported by app users. Targeted strategies aimed at improving awareness of digital health applications should be devised. Furthermore, institutions should invest in the development of these technologies, to minimize technical issues and make them accessible to the entire population.

“…Understanding public perception of these apps and reasons for downloading or not downloading them is important for tailoring app design and promotion to increase uptake and effectiveness in slowing COVID-19 transmission. Contact tracing applications have been used for other infectious diseases with variable success [14,15]. Prior to wide app implementation, studies from Europe and North America showed mixed public perception with issues of trust (i.e., security and privacy concerns, fear of surveillance) being common reasons for individuals not adopting them [16][17][18][19][20].…”

Drivers of downloading and reasons for not downloading COVID-19 contact tracing and exposure notification apps: A national cross-sectional survey

et al. 2022

Background Bluetooth-enabled smartphone apps have been developed and implemented in different sites globally to help overcome capacity limitations of traditional interview-based COVID-19 contact tracing. Two apps are currently available in Canada: ABTraceTogether exclusively in Alberta and COVID Alert in nine other provinces and territories. This study aims to examine factors associated with downloading of these apps to inform targeted promotion and marketing to increase app uptake. Methods We performed a cross-sectional survey with adult participants (≥18 years old) from an online national panel. Participants were asked if they had downloaded an app and, if applicable, reasons for not downloading. Logistic regression was used to identify sociodemographic factors and trusted information sources associated with downloading and reasons for not downloading. Results Of the included 4,503 respondents (36% response rate), 1,394 (31%) had downloaded an app. Demographic and socioeconomic factors positively associated with app download were: 1) being female, 2) higher household income, 3) higher education level attained, and 4) more liberal political views. The odds of downloading an app were higher for participants who trusted health-related information sources, and lower for those who trusted internet searches, family and friend, or Facebook. The most cited reasons for not downloading were related to data security concerns and perceived lack of benefit from the apps. Interpretation These findings identify sociodemographic segments with the lowest app uptake, reasons for not downloading and trusted information sources to inform targeted promotion and marketing strategies to improve uptake of apps to facilitate contact tracing.
