Résumé

The release of COVID-19 contact tracing apps was accompanied by a heated public debate with much focus on privacy concerns, e.g., possible government surveillance. Many papers studied people's intended behavior to research potential features and uptake of the apps. Studies in Germany conducted before the app's release, such as that by Häring et al., showed that privacy was an important factor in the intention to install the app. We conducted a follow-up study two months post-release to investigate the intention-behavior-gap, see how attitudes changed after the release, and capture reported behavior. Analyzing a quota sample (n=837) for Germany, we found that fewer participants mentioned privacy concerns post-release, whereas utility now plays a greater role. We provide further evidence that the results of intention-based studies should be handled with care when used for prediction purposes. © 2023 ACM.

Résumé

Case presentation: Supportive periodontal care (SPC) is defined as step IV by the 2020 and 2022 EFP Guidelines for the treatment of periodontitis stages I-IV. SPC aims to maintain periodontal stability after active periodontal treatment is finished and the endpoints of periodontal therapy are achieved. SPC presumes preventive and therapeutic procedures performed at individualised, patient-based intervals. This case report describes a patient, 43 y/o female, with diagnoses of generalised periodontitis stage IV, grade C and periodontal health on reduced periodontium who was enrolled in longterm SPC provided at 3 - 4-monthly intervals. During the COVID-19 pandemic, the patient did not report for regular SPC due to personal fears of the contagion. After 20 months of absence, the patient was admitted for SPC. The comprehensive periodontal exam showed excellent oral hygiene (FMPS=7%), the presence of five 4 and 5 mm pockets and relapse of periodontal inflammation (FMBS=42%). The affected areas were mostly in the lower jaw. As periodontitis is a chronic disease, patients need to be continuously monitored. SPC reduces the probability of disease progression and tooth loss, as timely re-treatment can be provided in cases of disease recurrence. Various factors can contribute to disease relapse. In terms of the described patient, despite good oral hygiene, factors such as psychological stress and unhealthy living habits experienced during the COVID-19 pandemic might have negatively impacted the innate host response and led to disease relapse.

Résumé

To help tackle the COVID-19 pandemic, the tech community has put forward proximity detection apps to help warn people who might have been exposed to the coronavirus. The privacy implications of such apps have been discussed both in academic circles and the general population. The discussion in Germany focused on the trade-off between a centralized or decentralized approach for data collection and processing and their implications. Specifically, privacy dominated the public debate about the proposed "Corona-Warn-App." This paper presents a study with a quota sample of the German population (n = 744) to assess what the population knew about the soon-to-be-released app and their willingness to use it. We also presented participants potential properties the app could have and asked them how these would affect their usage intention. Based on our findings, we discuss our participants' views on privacy and functionality, including their perception of selected centralized and decentralized features. We also examine a wide range of false beliefs and information that was not communicated successfully. Especially technical details, such as that the app would use Bluetooth, as opposed to location services, were unknown to many participants. Our results give insights on the complicated relationship of trust in the government and public communication on the population's willingness to adopt the app.
