“…A tabular summary of studies on various aspects of DCT apps in general and the CWA in particular can be found in Table 3 . As a summarizing comment, although there are studies that attempt to evaluate the effectiveness of DCT applications in general [ 17 ], only one study examined caseloads immediately before and immediately after the introduction of various interventions, including DCT apps [ 74 ]. There are no studies to date, neither in an international context nor in a national context specifically for Germany, that attempt to estimate the reduction in infection cases and their complications achieved by DCT apps over a longer period of time.…”

The COVID-19 pandemic posed challenges to governments in terms of contact tracing. Like many other countries, Germany introduced a mobile-phone-based digital contact tracing solution (“Corona Warn App”; CWA) in June 2020. At the time of its release, however, it was hard to assess how effective such a solution would be, and a political and societal debate arose regarding its efficiency, also in light of its high costs. This study aimed to analyze the effectiveness of the CWA, considering prevented infections, hospitalizations, intensive care treatments, and deaths. In addition, its efficiency was to be assessed from a monetary point of view, and factors with a significant influence on the effectiveness and efficiency of the CWA were to be determined. Mathematical and statistical modeling was used to calculate infection cases prevented by the CWA, along with the numbers of prevented complications (hospitalizations, intensive care treatments, deaths) using publicly available CWA download numbers and incidences over time. The monetized benefits of these prevented cases were quantified and offset against the costs incurred. Sensitivity analysis was used to identify factors critically influencing these parameters. Between June 2020 and April 2022, the CWA prevented 1.41 million infections, 17,200 hospitalizations, 4600 intensive care treatments, and 7200 deaths. After offsetting costs and benefits, the CWA had a net present value of EUR 765 m in April 2022. Both the effectiveness and efficiency of the CWA are decisively and disproportionately positively influenced by the highest possible adoption rate among the population and a high rate of positive infection test results shared via the CWA.

BackgroundContainment of the COVID‐19 pandemic has been impaired by the denial and defiance of preventive recommendations.AimsWe aimed to study the attitudes toward COVID‐19 social measures among laypersons and healthcare professionals.MethodsWe conducted a cross‐sectional study in the United Arab Emirates using a self‐administered online questionnaire. Both healthcare workers and laypersons were actively recruited. In addition to sociodemographic variables, the questionnaire included questions on anxiety, knowledge, and defiance related to COVID‐19.ResultsA total of 615 individuals with a mean age of 32 years (SD, 12) participated. Females comprised 69% and healthcare workers constituted 60% of the study sample. Among laypersons, over 42% reported having social gatherings at home, and 44% admitted to visiting crowded places. More than half of the respondents felt increased anxiety. Previous COVID‐19 infection did not affect attitudes or anxiety levels. Knowledge about COVID‐19 was higher among those who were more educated (r = .21). Healthcare workers had lower anxiety than laypersons (p = .002). COVID‐19 anxiety was higher among older persons and did not decrease with more knowledge. COVID‐19 defiance was higher among younger male respondents from larger households and did not correlate with knowledge. Multivariate analysis showed more defiant attitudes at younger ages.ConclusionsAnxiety‐related to the COVID‐19 pandemic is more common in older individuals, whereas younger persons were more likely to deny and defy prevention recommendations despite having knowledge of viral transmission. Voluntary compliance by young individuals requires an engaging communication strategy to generate more compassionate attitudes.
