Thank you, Progressive Citizen X/The Matt McNeil Show. Tomorrow, I will describe in detail what is currently going on and what to expect in the coming months. I will detail the other pathogens and outbreaks around the world. 🧪

You are a public health asset! We are in our 13th wave, which could be our 3rd or 4th largest, the public needs to know how serious SARS-CoV-2 is. The booster is well matched to the current dominate family, XFG*. Mask up with an N95 respirator, avoid large gatherings, and tell your loved ones too. 🧪

It was great to catch up with our disease modeling expert, Dr. @jlerollblues.bsky.social! Today we discussed the worst measles in generations, COVID's never-waning presence, the rise of the foodborne illness issue, and Avian Flu is back! Great... #Spotlight interview! soundcloud.com/am950radio/d...

DOCTORS ARE WALKING OFF THE JOB — and they say the system pushed them there. Nearly 150 unionized doctors at two Minnesota hospitals launched a 4-day strike after 3+ YEARS and 60+ bargaining sessions without a first contract. Their message: PATIENTS OVER PROFITS. They’re fighting

Thank you 👍🏼

All are XFG, however XFG = LF.7 × LP.8.1.2

🙏🏻🙏🏻 My last was LP-strain. A couple more and a win a pizza 😂😂

Many were at the beginning because we had no natural immunity, and the acute phase was also generally more severe. Omicron is also causing LC to a 5-25% rate. Many call it the brain eater. It also has a 50% asymptomatic rate because it has evolved toward immune escape rather than transmission. 🧪

Heartfelt, correct, and on point. Thank you, I hope it gets to the intended audience. 👍🏼 🧪https://beckyancirarobertson.substack.com/p/a-persistent-patient-821?r=18j8g4&utm_medium=ios

Unfortunately, the uptake of COVID vaccines continues to decline. This season's booster is well-matched to what is currently happening. 🧪
