When will the pandemic end? That's when people understand the importance of airborne transmission and realize how closely we are connected, when enough people are willing to transform from ego-centered pattern of thinking and acting into one that is based on compassion to others.

#COVID19 has highlighted controversies and unknowns about how respiratory pathogens spread between hosts. A 2021 #ScienceReview looked at recent advances in understanding airborne transmission gained from studying #SARSCoV2 and other respiratory pathogens. fcld.ly/lt8565g

Most recent SARS-CoV2 outbreak in HK fuelled by ‘vertical transmission’ in estate buildings, not explainable by common space sharing alone -likely upward aerosol spread via air shafts as reported for SARS-1

Perhaps no country has quashed #COVID19 better than #Taiwan🇹🇼. Even so, I feel TaiwanCDC can benefit from more focus on ventilation and aerosol spread. Would you join me in spreading the word that #COVIDisAirborne? As an example, I sent the following to policymakers👇 1/13

We all want our “normal” lives back. A key difference is many of us believe we can do it in a way that is equitable for all. Everyone deserves to breathe clean indoor air and there are solutions right in front of us. Adding air filtration is a key layer of protection.

Unfathomable. Why did it take World Health Organization (WHO) 2 years to say #COVIDisAirborne? nature.com/articles/d4158… feature nature by Dyani Lewis

There will be more virus in the air on public transit now. Buses > trains > planes. Even with great ventilation & filtration on airplanes, we found flu virus in 2 out of 3 samples, at ~10^4 gc/m3 years ago pubmed.ncbi.nlm.nih.gov/21300628/. /2

At last, an accurate article about the lack of mitigations in schools & the fight parents face to get HEPA filters in. It's clear that many poorly ventilated classrooms aren't being improved. Portrayal of most as being adequately ventilated is just a lie. bylinetimes.com/2022/04/25/hig…

Real-world evidence that increased ventilation rate and open windows are associated with less virus in the air. Note that ventilation rates were low (<1 ACH). Also, more virus found in air and on surfaces if subject was symptomatic vs. asymptomatic.

Improving ventilation, installing air filtration devices (HEPA filters) and implementing UV disinfection can effectively reduce the risk of indoor airborne transmission.

What if a cartoon explained a scientific article and was written and edited by scientist Chia Wang ? Watch, get educated and share. The same message goes for the flu, colds and RSV; they all live in virosols. The Quest of the virosols youtu.be/iFmxvZY69zI

Hooray! "ASHRAE...today announced its commitment to support the expedited development of a national indoor air quality (IAQ) pathogen mitigation standard. The goal is to finalize the consensus-based, code enforceable standard within six months." ashrae.org/about/news/202…

Facts. Masks reduce your risk of inhaling and getting COVID-19. Good fitting respirators work even better. Anyone who tells you differently is either misinformed, has a conflict of interest, ignorant, or brainwashed. Letting them control the dialog has led to this pandemic.

😮~60% of us who had COVID still might have lingering viral spikes in our heads! Our new study reveals SARS-CoV-2 spike accumulation in the skull-meninges-brain axis & its implications in long COVID. By Zhouyi Rong HongchengMAI Saketh Kapoor, PhD🔬🧠🦠🧵👇 biorxiv.org/content/10.110…

Our latest work published in J. Phys. Chem. Lett. shows that water actively enhances the formation of secondary organic aerosols in limonene ozonolysis, one of the most important sources of indoor SOAs!

Water can significantly enhance the total yield and composition of secondary organic aerosols by acting as both a catalyst and a reactant. Current atmospheric and climate models need to take water into account to accurately predict aerosol loading and their influences on climate!
