Open the windows to curb COVID spread, say experts

PARIS — Opening windows and ventilating spaces should be at the heart of efforts to prevent the spread of COVID-19, a group of experts said Thursday, arguing that confusion over airborne transmission meant this simple measure was being overlooked.

Mounting evidence convinced many places to adopt mask-wearing recommendations and health authorities have for months said that crowded, badly ventilated indoor spaces are a particular risk.

The virus is most likely to spread through inhalation at close range rather than through contact with surfaces or at long range, said respiratory experts said in a commentary published in the BMJ medical journal.

But despite this, the role of aerosol transmission gets “only a cursory mention in some infection control guidelines.”

“People are much more likely to become infected in a room with windows that can’t be opened or lacking any ventilation system,” they said.

The authors, including Julian Tang from the University of Leicester and Linsey Marr from Virginia Tech, said part of the problem has been a lack of clarity in the definition of terms such as “droplet” and “airborne” when describing transmission.

“Essentially, if you can inhale particles — regardless of their size or name — you are breathing in aerosols,” they said.

“Although this can happen at long range, it is more likely when close to someone, as the aerosols between two people are much more concentrated at short range, rather like being close to someone who’s smoking.”

At the beginning of the pandemic, health authorities, including the World Health Organization (WHO), discounted the possibility that simply breathing could send infectious micro-droplets into the air.

But they did a U-turn as experts piled on pressure and evidence mounted.

The BMJ commentary said precautions like wearing masks, keeping one’s distance, and reducing crowding in indoor spaces would all help curb viral spread, whether it was through inhaled particles or direct contact with surfaces.

But it stressed that a crucial difference was “the need for added emphasis on ventilation because the tiniest suspended particles can remain airborne for hours, and these constitute an important route of transmission.”

In March, the WHO released a guidance document encouraging better ventilation in buildings.

It said that while “knowledge gaps” remain, the transmission of the new coronavirus SARS-CoV-2 that causes COVID-19 is particularly effective in crowded, confined indoor spaces where there is poor or no ventilation.

Bakit ang isang tree hugger behaviorist kagaya ko eh tinatalo ko dsikarte ng engineer architect interiior designer eh napakabasic nito. FLOW OF THE AIR!!!!!

Ang dami mali sa design ng mga bahay ngayon. Lalo na yung gated type salubong townhouse eh barado hangin.

Tsikoteers paano ba yan mga views tumutumpak na naman!!!!

Am I troll?????

Balik topic ulit sa cooling:
Whitest-ever paint could help cool heating Earth, study shows | Environment | The Guardian

The whitest-ever paint has been produced by academic researchers, with the aim of boosting the cooling of buildings and tackling the climate crisis.

The new paint reflects 98% of sunlight as well as radiating infrared heat through the atmosphere into space. In tests, it cooled surfaces by 4.5C below the ambient temperature, even in strong sunlight. The researchers said the paint could be on the market in one or two years.

Dunno why nawawala to sa isip ko pag dating sa bahay, but white = cool is such common sense sa cars it should have been obvious.

Whitest ever is not white paint? Parang bang white version ng vanta black?

The big factor is it rejects UV which regular white paint still absorbs. This is what allows it to cool below ambient temp.

my two concerns,
1. price; and
2. longevity.

Problema nyan is village restrictions, here, we are allowed to choose from 6 colors only, bawal pa ang pareho magkatabi and white is not in the choices. With regards to roof, we are required to use asphalt shingles, wala ring white nito hehe

... strange policy...
but what do i now.
i don't live in a protected enclave.

Wow! Sobrang restriction naman bro - requiring asphalt shingles only for the roofing?

[papi smith]

Yes Sir CVT, in fact, may lower roof ako sa likod, hindi naman kita sa kalsada, pero shingles pa rin, sa gate pa lang di na makakalusot ang long span. Ung kulay ang malupit, kasi the only color my wife likes is the same as our neighbors, yun lang ang di nasunod sa gusto nya [emoji38]
