We noted yesterday that bizarre 5G coronavirus conspiracy theories were leading to mobile phone masts being set alight, and Facebook has now said that it is acting in response.

The social network says that it is now removing posts claiming a link between the rollout of 5G service and the spread of the coronavirus…

The Guardian reports:

It follows an announcement yesterday that YouTube would also be removing 5G coronavirus conspiracy videos.

A senior member of staff at one UK mobile network blamed the rapid spread of a map that purported to show an overlap between countries that had coronavirus cases and countries that had rolled out 5G. The map was not accurate on either measure.

Other viral claims emphasized other supposed coincidences. A popular claim that Wuhan was the first city in the world to receive 5G took hold. But Wuhan received 5G coverage in August 2019, almost 18 months after O2 launched its first London testbed for the technology on the Greenwich peninsula. Iran, meanwhile, has seen an incredibly high number of coronavirus cases despite not having any 5G coverage.

Separately, Reuters notes that some US Facebook users will be invited to take part in a health survey.

The social media giant will display a link at the top of users’ News Feeds directing them to the survey, which the researchers say will help them predict where medical resources are needed. Facebook said it may make surveys available to users in other countries too, if the approach is successful […]

Facebook said in a blog post that the Carnegie Mellon researchers “won’t share individual survey responses with Facebook, and Facebook won’t share information about who you are with the researchers.”
