Our new @IHME_UW #COVID19 projections are out. Estimated infections are declining and reported cases have remained roughly stable in the US overall. 1/
covid19.healthdata.org/global?view=cu… Given the widespread use of rapid antigen tests, we estimate the infection-detection rate has declined to nearly 4%. With such a low infection-detection rate, the BA.5 surge that likely peaked in mid-July may have infected a substantial fraction of the population. 2/ Image

@IHME_UW does not project a #COVID19 surge in the US in the coming weeks similar to what we have seen in parts of Europe. Our models suggest that after the end of March there should be a steady further decline in transmission. 1/ Image Estimated infections, reported cases, hospital census, and daily deaths continue to decline. Despite a steady return to pre #COVID19 behaviors, transmission continues to decline. 2/ Image

The #Omicron surge is creating unprecedented levels of transmission: the daily infections are estimated to have reached 125 million, ten times the #Delta wave peak in April 2021. @IHME_UW 1/
covid19.healthdata.org/global?view=cu… The massive surge in infections, however, is not leading to a 10x increase in deaths because #Omicron is 90-99% less severe. Lower severity is due to three factors: 1) the fraction of people with asymptomatic infection is up from 40% to 80-90%; 2/

#Omicron is likely to have spread to nearly all countries by now. The larger fraction asymptomatic means that the massive surge in infections will lead to a smaller but sill unprecedented increase in reported cases. 1/ Hospitalizations will increase, and in some countries this increase will lead to higher levels of hospitalization than in previous surges, including the Delta wave and the Northern Hemisphere winter surge last year. 2/

No amount of media training can fix bad messaging, @CDCDirector. The root of this problem, the problem of back and forth messaging coming out of the @CDC_gov, cannot be fixed by one individual working on their personal communication skills. 1/
cnn.com/2022/01/07/pol… It worries me that @CDCDirector told @CNN: "We actually don't know how our rapid tests perform and how well they predict whether you're transmissible during the end of disease." We need to know how well rapid tests perform at this point in the pandemic. 2/

Wishing a very warm happy holidays to all – we deserve to celebrate even amid immense hardship. I have been asked frequently about safe travel and gatherings for the holidays amid #COVID19 lately. Here are my thoughts. 1/ 🔑 Being vaccinated against #COVID19 and getting a booster as soon as its available to you is absolutely key to gather safely this holiday season.

Also get a flu vaccine to further protect yourself and your family. 2/

There are early indications that the decline in the Delta surge at the national level in the US has ended. 19 states have increasing transmission, including a number of states such as AZ, CA, and NM that had previously appeared to have been declining. 1/ It is clear that the notion that #COVID19 is over is very unlikely to be true. 2/
