1. Amazing statistic: In the 10 weeks since Omicron was discovered, there have been 90M #Covid cases reported — more than in all of 2020, says @drtedros at today's @WHO press conference.
2. A dangerous narrative on the pandemic has taken root, says @drtedros. With the availability of vaccines & the transmissibility of Omicron, some are assuming the need to fight to reduce transmission is either unnecessary or futile. More infections will lead to more deaths.
3. @drtedros said the #SARSCoV2 virus remains dangerous and continues to evolve. @WHO is monitoring 4 subvariants of Omicron, he said.
4. Lots of Qs today during @WHO's press conference about countries lifting #Covid measures. Countries are at different points in their outbreaks, depending on vaccination rates & other factors & @DrMikeRyan warned countries should only lift measures when local conditions warrant.
5. @DrMikeRyan said he worries countries may be following others, lemming-like, rather than making decisions because transmission locally has reduced. He warned that countries that are opening up need to be ready to reinstate control measures if the need arises.

1. A short #flu 🧵
Flu activity in the US remains low for this time of year. For the week ending Jan 22, 1.9% of samples tested for flu were positive. To put that in context, in the corresponding week in 2019-20, the positivity rate was nearly 28%.
2. #Flu activity in the week ending Jan. 22 was roughly equal to the previous week, @CDCgov reports. But transmission of other respiratory pathogens has declined, which have brought the epi curve for #influenza-like illnesses (ILIs) for this season almost back down to baseline.
3. It's early in the flu season for this kind of decline; there could be a rebound later.
Is the decline due to precautions people are taking to avoid Covid? Is Covid beating the other ILIs to the punch — it's infecting people before flu or other ILIs can? I'd love to know.

1. A #flu 🧵 based on US data from @cdcgov.
Two children died from flu in the week ending Jan. 15, bringing to 5 the total number of pediatric flu deaths so far this season. It's a such a shame to see this feature of flu season return.
2. #Influenza-like illnesses dropped again last week. The further we get out from the holidays, the more likely it is that's a real thing, not an artifact of reporting delays. Is the Omicron wave crowding out flu? Are measures people are taking to avoid Omicron driving down flu?
3. #Influenza-like illness activity (which is #flu, RSV & a range of other non-Covid respiratory pathogens) is incredibly variable this year. It's unusual to see some areas reporting very little (green) & others lots (deep red). In a regular flu season, it's more homogeneous.

1. A #flu 🧵, based on U.S. data for the week ending Jan. 8.
There has been another pediatric death from flu, the third this season. It occurred in the week leading up to Christmas. Pediatric flu deaths are still at very low levels relative to regular flu years, thankfully. Image
2. #Flu activity is still at low levels & it actually dropped last week. Is that because of data filing delays over the holidays? Because people are avoiding health care because of Covid? Or is Omicron somehow crowding out flu? Need someone smarter than me to answer that Q. Image
3. Hospital admissions for flu decreased a little last week. That probably suggests some decline in #flu activity.
Will flu activity pick up again? Most flu seasons don't peak until late January, into February. The size of the Omicron wave, though, could be an influence here. Image

1. There is a new global flu report out from @WHO, so, a 🧵.
#Flu activity is picking up globally after the historic low levels seen in the first year & a half of the #Covid19 pandemic. In some places, WHO says, activity is now at levels see before the pandemic.
2. @WHO didn't stipulate which countries are experiencing as much #flu now as they would have at a corresponding time of the year in the pre-pandemic era. I've asked & will add the info if I get it. It could be in parts of Europe. This from @ECDC_EU.
3. The global positivity rate for the period from Dec. 6 to Dec. 26 was 5.2%, which is above where it was in mid-March, 2020 when #flu activity worldwide collapsed.
The new rate is based on more than a half-million diagnostic tests conducted across 110 countries.

1. A flu 🧵, because it's Friday.
We're definitely into #flu season, but this is not like the flu seasons of yore. (Not yet, anyway.) Still, it's important to remember hospitals are overwhelmed with Covid. Flu on top of Covid is an additional stressor the system doesn't need.
2. Things appear to be heating up in many parts of the country, though this map charts influenza-like illness, which is more than just #flu. @CDCgov reports that the NE and Central parts of the country are reporting more #influenza than the west.
3. The data in this week's FluView covers the week ending Jan. 1. Reports from over the holidays can sometimes contain incomplete data, which may explain this week's test positivity rate, which is 3.8%. That's down from 6.2% the week before. I doubt flu is actually abating.

42. #ACIP member Pablo Sanchez, who has been one of the most vocal about his concerns about vaccine-associated myocarditis, is supportive of a *should* recommendation. To borrow a phrase from elsewhere: I've seen enough.
43. #ACIP member Keipp Talbot says "this booster will not be a hammer" becoz too many 12-15 yos aren't vaccinated at all.
"Boosters are incredibly important but they won't solve this problem of the crowded hospitals." Talbot thinks efforts should focus on getting kids dose 1 &2.
44. When #ACIP votes (probably in the next few minutes) it will be on a *should* recommendation.
Which means the vote will be about recommending kids 12-17 should get a booster. 16 & 17 yos are included because currently the recommendation for them is a *may* recommendation.
