A thread of examples of much-needed pushback against public health calm-mongering. It's not about causing panic (which doesn't happen anyway), it's about acknowledging uncertainty and implementing the precautionary principle. 🧵 First, what is calm-mongering? open.substack.com/pub/typingmo...

Back in those whimsical days of the pandemic emergency you might recall a public health communications strategy titled ‘do your own risk assessment’. At the time those who know something of formal Qual/quant risk assessments pointed out that this was not something that anyone could do.

Our central argument: for severe pathogens with respiratory transmission potential, public health agencies should START with stringent airborne precautions and scale back only if evidence later justifies doing so — not the reverse. 6/

The key public health question is not whether Andes virus is as transmissible as measles or SARS-CoV-2. It is whether a pathogen with documented human transmission and a case fatality rate (by WHO's own estimate) of ~38% warrants stronger airborne precautions. We argue yes. 5/

Evidence for person-to-person transmission of Andes hantavirus has existed for nearly 30 years. The Epuyén outbreak included infections after brief indoor exposure without physical contact — entirely consistent with respiratory aerosol spread. 2/ www.nejm.org/doi/pdf/10.1...

OUR NEW BMJ editorial: Andes virus should reset WHO’s default approach to airborne risk. 🧵 1/ For severe pathogens with person-to-person transmission, the starting point should be precautionary airborne protections — not waiting for definitive proof after spread occurs. www.bmj.com/content/393/...

I don't think sending cruise ship contacts on international commercial flights without PPE or serial testing, nor mandating quarantine afterwards is smart public health. These are the kinds of decisions that get you into trouble, even if this outbreak stays relatively small.

they still seem to have difficulty saying the word airborne for whatever reason. instead of saying “institute airborne precautions” instead they say “implement transmission-based precautions”

Here's the Canadian Standards Association's tool for selecting standards-compliant PPE, created by actual experts (i.e. not the quacks in public health / IPC leadership). Select "healthcare" and then "hantaviruses". You're lucky if your hospital has 3-6 ACH. Medical masks are level 0, N95s are 1. 🤨

Hospitals are dangerous places. Air purification would mitigate the risk. Too bad most infection control professionals have voted for job security over patient safety, as I recently experienced up close and personally. This is by no means the first paper to make these points. > Despite good […]

I really despise how risky hospitals are for respiratory transmission today. Its mitigatable right up to the point you have an issue that makes it not mitigatable. Hospitals should not be a place of unmanaged risk resulting in health danger. #COVIDisAirborne

Modeling flu and Covid out suggests a 0.04% IFR for covid, and also suggests we are still undercounting acute covid deaths to an extent.

We continue to avoid the key lesson of #covid - we have to sanitize our exhaled waste air like we sanitized our food & water waste in the 19th century. Until we centralize air sanitization into HVAC, we won't defeat airborne diseases like covid, flu & RSV. And many others. ASHRAE has given us […]
