Droplets vs Aerosols: What’s More Important in COVID-19 Spread?

Source: https://www.medpagetoday.com/special-reports/exclusives/92564

Last week the CDC changed its guidance about the transmission of SARS-CoV-2, recognizing airborne spread as a key mode of infection.
The new guidance acknowledges that inhalation of aerosols — which are tiny, lightweight viral particles that can float and linger in the air for extended periods of time — is one way COVID-19 spreads. Even when an infectious person is more than 6 feet away, aerosols have the ability to travel and infect others. Following a similar change made recently by the World Health Organization (WHO), the CDC guidance acknowledges three primary routes of SARS-CoV-2 transmission: inhalation into the lungs, deposition of droplets onto the face, or touching infected surfaces, also known as fomites.

Experts say more measures needed to address COVID-19 aerosol transmission

More than a year into the novel coronavirus pandemic, Canadian experts say changes are needed to address the indoor transmission of COVID-19 aerosols, tiny particles or droplets that can stay in the air.
They say the current infection control protocols in place don’t adequately help to curb the airborne transmission of COVID-19 and that officials need to pivot to target the appropriate areas, like ventilation and proper mask-wearing.

Droplet, aerosol, airborne: The confusion over how COVID-19 spreads

Source: https://globalnews.ca/news/7838988/droplet-aerosol-airborne-how-covid-19-spreads/

Conflicting messages from public health authorities and experts have fuelled a great deal of confusion and debate over COVID-19, particularly regarding its transmission.
The terms “droplet,” “aerosol” and “airborne” are used when trying to explain how viruses are spread.
For more than a year, health officials and experts have said COVID-19, a respiratory virus, is spread via droplets.

Droplet, aerosol, airborne: The confusion over how COVID-19 spreads

Source: https://calgaryherald.com/news/local-news/alberta-response-to-airborne-covid-19-transmission

Alberta is updating its mask-use guidelines in the light of a recent messaging shift from Canada’s top doctor on the risk of airborne spread of COVID-19, but the province is otherwise continuing to use a year-old document which considers aerosol virus transmission to be a non-dominant form of spread. Dr. Theresa Tam, Canada’s chief public health officer, said in mid-November that respiratory aerosols — microscopic airborne particles which can carry SARS-CoV-2, the virus that causes COVID-19 — can linger in air much like smoke , underlining the importance of mask use and ventilation in indoor spaces as virus mitigation measures.

Ten scientific reasons in support of airborne transmission of SARS-CoV-2

Heneghan and colleagues’ systematic review, funded by WHO, published in March, 2021, as a preprint, states: “The lack of recoverable viral culture samples of SARS-CoV-2 prevents firm conclusions to be drawn about airborne transmission”.1 This conclusion, and the wide circulation of the review’s findings, is concerning because of the public health implications.

Why indoor spaces are still prime COVID hotspots

When Lidia Morawska leaves home, she takes with her a slick, shoe-sized device that provides some sobering insights about the restaurants and offices she visits. Outside these buildings, her carbon dioxide monitor reads just above 400 parts per million (p.p.m.). But indoors is a different story.

COVID-19 will probably become endemic – here’s what that means

Source: https://theconversation.com/covid-19-will-probably-become-endemic-heres-what-that-means-146435

We can’t say with any certainty what the future of COVID-19 is. But based on our experience with other infections, there is little reason to believe that the coronavirus SARS-CoV-2 will go away any time soon, even when vaccines become available. A more realistic scenario is that it will be added to the (large and growing) family of infectious diseases that are what is known as “endemic” in the human population.

239 Experts With One Big Claim: The Coronavirus Is Airborne

Source: https://www.nytimes.com/2020/07/04/health/239-experts-with-one-big-claim-the-coronavirus-is-airborne.html

The W.H.O. has resisted mounting evidence that viral particles floating indoors are infectious, some scientists say. The agency maintains the research is still inconclusive. The coronavirus is finding new victims worldwide, in bars and restaurants, offices, markets and casinos, giving rise to frightening clusters of infection that increasingly confirm what many scientists have been saying for months: The virus lingers in the air indoors, infecting those nearby.
