1/ Q: Our neighborhood #pool plans to reopen in a couple of weeks when our state eases lockdowns. Is the pool a risky place for #COVID19 transmission?

A: You're unlikely to get #Covid_19 *from* the pool, but you could certainly be exposed *at* the pool. More in this thread
2/ To clarify: Pool water is heavily chlorinated, and #COVID is not waterborne in any case. So, being immersed in the pool or otherwise exposed to pool water is not risky in and of itself.
3/ The problem, of course, is all those other folks who want to enjoy the pool, too. Close, sustained contact with others during physical exertion (splashing, swimming) and other activities that cause heavy exhalations ("Marco!" "Polo!") is conducive to #COVIDー19 transmission.
4/ While It's helpful that most pools are outdoors (where transmission risk is generally lower), it doesn't guarantee no #transmission. Indeed, we just learned as we were drafting this post about a high school swim party in Arkansas that led to multiple COVID-19 infections.
5/ The likelihood of neighborhood pools/swim clubs opening this summer varies by region. Some places have already decided that they will not open this summer, while others plan to reopen if they can accommodate @CDCgov and local guidance. Others opened on schedule this weekend.
6/ How to make summer pool visits more safe? The staff at your pool is likely already planning for and implementing measures to
👥 limit attendance at the pool,
📏 enforce distancing both in the pool and in the surrounding areas, and
🧼maintain strict hygiene.
7/ Recent guidance from the CDC also recommends additional staff to monitor and enforce distancing and attendance limits, so that lifeguards can focus on swimmer safety.
8/ You can help by making sure you and your kids follow all rules about masking (yes, you're likely to be asked to #mask), opening and closing times, #SocialDistancing, and locker room protocols. If you're confused about the rules, or concerned about transmission, speak up.
9/
Finally, avoid sharing gear, toys, and refreshments with others. Keep your visits shorter than you might otherwise do.

Nope, it won't be the same. But hopefully with some sensible guidelines and attentive behavior, the pool can be a safe and fun respite.
10/

How can I stay safe during the holidays?

➡️Think in terms of harm reduction. Don’t let the perfect be the enemy of the good.

#covid #rsv #flu #HolidaysAreComing

1/
2/ Just in time for Christmas, #COVID is again on the rise.

#Flu and #RSV may be peaking—but remember that there are often as many cases *after* a peak as before it.

dearpandemic.org/are-cases-peak…
3/ How can we enjoy moments w/ family & friends & lower the risk of illness?

💥 Small steps you take to reduce risk are worthwhile. A little bit better…is a little bit better.

Prevention steps that work for COVID will reduce the risk of RSV, flu, & many other nasty viruses.

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.

dearpandemic.org/numbers-infect…
2/ A recent @CDCgov MMWR report estimated seroprevalence from a convenience sample of blood collected for medical tests.

➡️Roughly 58% of Americans showed evidence of previous SARS-CoV-2 infection in their blood by Feb '22.

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.

1/Q: Did getting exposed to fewer germs for the last 2 years weaken our immune systems?

We've been hearing this question a lot.
dearpandemic.org/fewer-germ-exp…
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).

dearpandemic.org/are-cases-peak…
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:

1/ Q: Case numbers are jumping QUICK! What should I be doing?

A: Share your gifts without sharing COVID. Helpful gestures come in many shapes.

2/ One HUGE help: Cancel non-essential plans.

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).

1/ Q: Is it true that #Omicron is less severe than previous variants?

A: We HOPE so, but we don’t know yet. The evidence so far is mixed.

dearpandemic.org/is-omicron-les…
2/ We are WAY past due for some good variant news. But pinning our #Omicron hopes on a less virulent variant is not wise for 2 reasons:

1) It might not be less severe in those who are “immune naïve” (neither vaccinated nor with a previous infection—still millions of people).
3/ 2) Many more infections *even* if less severe can still lead to an avalanche of hospitalizations and deaths, and the risk of long Covid.
