Once again, the WHO official who reported that asymptomatic spreading was rare has walked back from that position. According to the report in the NY Times scientists at other organizations objected to her statement and provided a link to another widely cited paper
https://www.nature.com/articles/s41591-020-0869-5 published in April that estimated that 44% of new infections were from asymptomatic people.
I agree that that was April and we're in June now, so things may have changed. However with the walk back by the official I'll be waiting for more reports before relaxing my efforts to improve my chances of not spreading it and not getting it.
Science is often an iterative process and I myself am not bothered by statements which contradict previous statements. It's all part of the way we gain knowledge about new things and situations.
