It’s great that flu vaccine uptake is high, we need Covid vax uptake to be high as well, and available to children. Clean the air! https://t.co/7rebCx8Aym

I’m so incredibly frustrated. We have an outbreak report for the cruise ship, published in NEJM, and great clinical, epidemiological, and genomic reporting, and…

NOT A SINGLE MENTION OF VENTILATION/FILTRATION SETUP ON THE SHIP

Folks, we keep doing this. A lot of MD/PhD coauthors on the “Andes Virus Outbreak Working Group”, and no one with expertise on mechanical systems. And no one on the team even thought to check or investigate it.

It’s malpractice at this point, and I’m not exaggerating in my use of the term. I do investigations in buildings and if I failed to check the status of the mechanical systems I’d be sued. (It’s actually *the first* thing I check)

@NEJM: see our report from The Lancet COVID-19 Commission on this in the thread. Include this in your reviews. Mandate this info in every outbreak investigation report.

The reason I first called the doctor on the ship was because I wanted to see if he could get info on the ship’s systems before he left it, bc I knew the official investigations would miss it. Because they always do.

“Imagine getting a nasal spray in the fall months that protects you from all respiratory viruses including COVID-19, influenza, respiratory syncytial virus and the common cold, as well as bacterial pneumonia and early spring allergens…That would transform medical practice.”

[Stanford Medicine @StanfordMed]

Stanford Medicine researchers and their colleagues invented a new vaccine that shows potential to protect against respiratory viruses, bacteria and allergens — the closest yet to a universal vaccine.

However, the Z score for 10 source cases (number of secondary infections per case; figure from 1️⃣) indicates that only those with viral loads > 1.23 × 10^7 copies/mL were sources in this outbreak.
NOTE: samples are the earliest collections

Droplet and close contact transmission = misunderstood aerosol (inhaled/ airborne/ 'through the air) transmission that occurs at close range (where concentration is high) or between 'close contacts' who've spent a lot of time sharing air e.g., in a household.

@NukitToBeSure I heard a presentation from lead author of this paper a few years ago. My understanding was they used air cleaners in front of nursing stations to act like an air curtain.They said cross infections dropped considerably https://t.co/NRX3AAdIaF your thoughts on that as a strategy?

Version 3.
I've extended the orange-shaded area to cover the full 45 days (WHO number) and indicated each week since the date post-onset of Case 1's symptoms (dpo).
May 10th was a day when 2 people became symptomatic and also tested positive. I've used green

Exactly this: ‘Still: just don’t get on flights or go to birthday parties if you feel ill. Sometimes it’s good not to share 🤣’

[Emma Hilton @FondOfBeetles]

I know the boat didn’t really recognise they were dealing with hantavirus, and made some decisions that look poor *In hindsight*.

But this is not COVID.

Still: just don’t get on flights or go to birthday parties if you feel ill. Sometimes it’s good not to share 🤣

🧵A Whangārei GP told RNZ this week: "There's no such thing as a straightforward consult." He meant it as a complaint. He also named the impossibility at the heart of NZ's entire primary care funding model. #nzpol 1/ https://t.co/mo3SyX1RfZ

@SmartairUk That is fantastic news!

The recently published Covid Inquiry Module 3 report clearly states that:

“In the short-term [until all hospitals can be equipped with effective ventilation systems], the use of HEPA filters should be PRIORITISED within healthcare across the UK.”

Indoor Air Quality: An Overdue Awakening

It was an absolute joy to work w/ Dr. Linsey Marr on this ES&T Viewpoint opinion piece.

Has it really been 26 yrs since I wrote about the need for clean air act amendments to address indoor air quality? Time!🕚
