I watched sky new last night.
Their covid fact sheet that come up on TV has 72 hour on surface still despite the current thinking that these trace amount of virus material isn't enough to infect a person.
They also had interview with pediatrician around the letter several thousand had signed and sent to Government about the desperate need to get children back to school.
It was their covid news reader doing interview who seemed shocked to hear children weren't superspreaders - that in last few months we'd learnt a lot and several studies showed they got it less frequently, less severely and passed it on to adults they lived with very rarley and thus school were less a risk than offices.
Maybe it's mix of poor risk assesmenet and just out of date information that's making people seem crazy.
