(🧵1/5, EMERGENCE): What happens to virulence after a new pathogen emerges? Popular thinking on the subject is that pathogens evolve become less virulent over time when they co-exist with their host species, based on the logic that virulent pathogens don't spread effectively.(1/)

Opinion: What you should know about COVID this fall

“How is COVID-19 spread? When people cough, sneeze or talk, viral particles can be sent through the air and via droplets. Masking helps to prevent droplet spread, and keeping more than two metres apart and staying in a well-ventilated area can help to limit aerosol spread.

While not a predominant cause of transmission, COVID-19 can also be spread through objects contaminated with secretions from an infected person. The incubation period for COVID-19 — the time from exposure to developing an infection — is about two to four days with the current variant.”

SARS-CoV-2 Survival on Skin and its Transfer from Contaminated Surfaces
SARS-CoV-2 Survival on Skin and its Transfer from Contaminated Surfaces
“How efficiently SARS-CoV-2 TRANSFERS from CONTAMINATED SURFACES (plastic, metal, of doorknobs, tables, phones, credit cards, toys, ...) to HUMAN SKIN, and how long the VIRUS SURVIVES on SKIN
While extensive research has examined the persistence of SARS-CoV-2 on various surfaces, there is limited understanding of how efficiently it transfers to human skin, and how long it survives on the skin. This study investigates two key aspects of SARS-CoV-2 transmission: (1) the transfer efficiency of SARS-CoV-2 from non-porous (plastic and metal) and porous (cardboard) surfaces to a 3D human skin model (LabSkin), and (2) the survival of SARS-CoV-2 on the skin under different temperature conditions.

‘World Health Organisation Doomed the World by Concealing Evidence of Airborne COVID Transmission’

“A former senior advisor on SARS has accused the World Health Organisation (WHO) of covering up its own evidence proving the airborne transmission of COVID-19, since the earliest days of the global pandemic. “

MASSIVE public health failure, and huge misinformation and propaganda win for both political parties.

Outbreak investigation of airborne transmission of Omicron (B.1.1.529) - SARS-CoV-2 variant of concern in a restaurant: Implication for enhancement of indoor air dilution
In May of 2021, Hong Kong required air purifers be placed in their restaurants after papers like this showed that you could be infected in just 19 minutes, median exposure time 34 minutes, while eating at a restaurant.

What would an adequate COVID response look like?
“Refusal to directly communicate 1) how COVID spreads 2) that it can be avoided 3) how it can be avoided while modeling mitigation, makes pandemic communications much more difficult for vulnerable people, activists and marginalized groups attempting to reduce disease burden in their communities. We should not be swimming against the current of public health officials’ poor pandemic hygiene.”

Oops! Looks like Covid IS airborne, folks.

COVID virus evolves more rapidly in the CNS

New viral variants created in the brain & other parts of the nervous system could also travel back to the lungs, where they could become transmissible. That could spread new, dangerous variants of the virus.

N95 Masks Nearly Perfect at Blocking COVID, UMD Study Shows

Researchers Found Even Lower-Performing Masks Were Protective

“The researchers also found that—in what might come as a surprise to many—cloth masks outperformed the specific brand of KN95 mask that was tested. Surgical masks brought up the rear in performance out of the four types, but even they blocked 70% of the virus, the tests showed. (To reflect the general public's use of masks, study volunteers were not fit-tested for their masks or trained how to properly wear them.)

‘The research shows that any mask is much better than no mask, and an N95 is significantly better than the other options. That’s the No. 1 message,’ says the study’s senior author, Donald Milton, a professor of environmental health and a global expert on how viruses spread through the air.”
