An anonymous reader quotes a report from Ars Technica: Because of the lag between infection and the onset of symptoms, people can contract the SARS-CoV-2 virus and then pass it on, potentially to many others, before they know they’re infected and have to isolate. So being able to identify and warn individuals who have been exposed to an infected person — known as contact tracing — is widely acknowledged to be a vital part of any effective strategy to beat COVID-19. Which is why it is extremely dismaying to see survey data that says fewer than 3 in 10 Americans intend to use contact-tracing apps to allow that to happen. The data was gathered from an online survey of just over 2,000 people in the United States, collected on June 1 by polling company Opinion Matters on behalf of the security company Avira. When asked if they planned to download a contact-tracing app, an overwhelming majority — 71 percent — answered no. Not only is that bad, it appears to be a deterioration from earlier this year; in April, we covered a poll that found 1 in 2 Americans would probably or definitely not use a contact-tracing app. Most of the resistance to downloading a contact-tracing app came from people over the age of 55. US Centers for Disease Control and Prevention data show that people aged 55 and over account for almost 80 percent of US COVID-19 deaths to date. “The most common reason cited was a concern about privacy; in all, 44 percent of those who said ‘no’ to a contact-tracing app said they would not trust the technology to protect their digital privacy,” the report adds. “But nearly as many (39 percent) also said they thought the apps created a false sense of security, and 37 percent said they believed the apps would not work to slow the spread of the pandemic. Thirty-five percent also indicated a lack of trust in the app providers.” Read more of this story at Slashdot.
