"Where There Is Light, There Is Also Darkness": Discussing Young Adults' Willingness to Disclose Data to Use Wearables and Health Applications-Results from a Focus Group Study.

In recent years, the Internet of Medical Things (IoMT) has gained momentum. This development has only been intensified by the current COVID-19 crisis, which promotes the development of applications that can help stop the virus from spreading by monitoring people's movements and their social contacts. At the same time, it has become increasingly difficult for individuals to control the use of their private data by commercial companies. While Internet users claim to be highly interested in protecting their privacy, their behaviors indicate otherwise. This phenomenon is discussed in literature as the so-called privacy paradox. The existence of the privacy paradox has also been confirmed by previous studies, which found individuals' claims and actions to contradict one another. The present study investigates the following research questions: (1) What significance do individuals attribute to protecting their privacy, with a special focus on the health sector? (2) To what extent are they willing to grant commercial parties access to their data in order to use applications in general and health applications in particular? Results from seven focus groups with 40 respondents aged 20-30 years were conducted in an urban setting in Austria in late 2019. The respondents' inputs are meant to provide answers to these questions. The results indicate that, overall, the young generation is well-informed about the growing data collection and is quite critical of it. As such, their willingness to share information in the health context is only moderately pronounced. Thus, only a moderately pronounced privacy paradox can be detected for the health sector when compared to other sectors. In conclusion, implications and directions for further research are addressed.

Experimental aerosol survival of SARS-CoV-2 in artificial saliva and tissue culture media at medium and high humidity.

SARS-CoV-2, the causative agent of the COVID-19 pandemic, may be transmitted via airborne droplets or contact with surfaces onto which droplets have deposited. In this study, the ability of SARS-CoV-2 to survive in the dark, at two different relative humidity values and within artificial saliva, a clinically relevant matrix, was investigated. SARS-CoV-2 was found to be stable, in the dark, in a dynamic small particle aerosol under the four experimental conditions we tested and viable virus could still be detected after 90 minutes. The decay rate and half-life was determined and decay rates ranged from 0.4 to 2.27 % per minute and the half lives ranged from 30 to 177 minutes for the different conditions. This information can be used for advice and modelling and potential mitigation strategies.
