Are you a #runner or #biker? Beware the "slipstream" and keep more distance!
"Based on the results, @BertBlocken advises to keep a distance of at least 4 to 5 meters behind the leading person, 10 meters when running or cycling slowly and at least 20 meters when cycling fast."
"If you want to overtake someone, it is also recommended to start "presorting" into a staggered arrangement from a fairly long distance – twenty meters with bicycles, for example, so that you can overtake carefully and at a proper distance by moving in a straight line."
"The simulations show that #SocialDistancing plays less of a role for two people who walk or run side by side in calm weather. The drops then end up behind the duo.
Those who move in a staggered arrangement are also less likely to catch the other's saliva droplets, at least when there is no substantial cross‐wind. The risk of contamination is greatest when people walk/run closely behind each other and therefore in each other's slipstream."
1/ Q: Has almost everyone been infected with COVID by now?
A: Recent estimates suggest around 58% of the population in the US and over 70% in England have been previously infected, with BIG increases during the Omicron wave.
3/ ➡️ During the Omicron wave from December 2021-February 2022, this estimate increased from 33% to 58%.
➡️ Rates vary a lot by age, ranging from 33.2% for those over age 65 to 75% for those under age 18.
2/ Not likely. If your kids are suddenly getting sick a lot, this is likely due to “catching up” on exposures rather than a weakened immune system.
3/ Many families w/ young kids have been hunkered down for the better part of 2 years– a good % of a young child’s entire life. While isolation had *many* downsides, we can agree that not having to suction snot out of infant noses or clean up norovirus puke was a happy upside.
1/ Q: Are cases peaking? That means it’s all downhill from here, right?
A: Sort of…. Remember that even if cases come down as quickly as they rise, there will be as many cases *after* the peak as before (think area under the curve).
2/ ➡️ And if the downward slope is *slower* than the rise, we will see *more* cases during the decline from a surge.
3/ Burning fast could be a silver lining of super transmissible #Omicron. Cases rose & fell quickly in S. Africa (w/ hospitalizations & deaths still lagging). The UK appears to have turned the Omicron corner. Many US states appear past their peak in cases, w/ regional variation:
Unfortunately, this includes New Year’s Eve plans. The perfect storm of a new variant & holiday get-togethers is hitting communities & health care w/ FORCE! Testing is in short supply.
3/ Health care is under extreme pressure with surging cases. If you can avoid even one additional contact, you are helping. This is a temporary and urgent request (from a health care provider).
