[Thread] #Restaurants

↔️ spaced tables do not protect from airborne spread over 2m

🍽 eating & talking indoors without masks is high risk of super-spread

🪟🌬building reg ventilation standards aren’t enough to stop virus build up

🦠visors don’t protect staff 1/ #Covid19
..
📈🌬 wall & ceiling-mounted ‘air con’ units can make it worse, by blowing virus around 2/

Super-spread in restaurant in China @businessinsider businessinsider.com/how-restaurant…
🚻 in poorly ventilated toilets, lobbies, staff areas, kitchens, storage & cold rooms, virus can linger in air for hours

🧼 🙌 transmission from surfaces is low, clean air is more important than clean hands

🌬Perspex screens don’t stop airborne virus, & can trap stale air 3/
🪟open windows, roof-lights & smoke vents

♻️turn vent systems to full fresh air (no recirculation), fit MERV filters

🔃use air purifier fans

📉use CO2 meters to catch poor air quality

🪴sit customers outside

Lots of interest in #Covid19 #ventilation (finally!) so he’s a round up of threads to stop the virus spread
(many threads are webpages here: threadreaderapp.com/user/Orla_Hega… ) 1/
#Covid19 is inhaled, avoid it by breathing clean air 2/
#Covid19 spread can be easily reduced by manipulating indoor air conditions 3/

Science denial from @VFIpubs on @morningireland
.. 2 metre distance is not safe, #Covid19 builds up quickly & spreads like cigarette smoke indoors, pubs & restaurants are the highest risk of large super-spread events, & it’s proven internationally #pubs
(does this really need saying)
Covid doesn’t know if it’s a gastro pub or wet pub, or after closing time, or what the Level is, or what your dinner cost, or if you ate it, or if you’re 6km away, or only went in for 10 minutes

You catch it by inhaling virus in shared indoor air
HIQA advice to NPHET:
🦠 large numbers of clusters consistently observed [in] bars, nightclubs, restaurants, gyms
🦠 & many associated with superspreading events & large numbers of cases
🦠indoors, crowds, no masks, talking/singing, poor ventilation

International science:
‘Restaurants & pubs are highest risk for indoor super-spread, as virus builds up quickly in air & nobody wears masks’

Ireland:
‘Restaurants & pubs to be ‘key battleground’ in lockdown exit talks’

Is #Covid19 in these talks?
irishtimes.com/news/politics/…
Cork: ‘57 confirmed cases of Covid-19 were linked to a cáfe-restaurant where people from different households socialised’ #superspread
echolive.ie/corknews/Covid…
South Korea: ‘one infected person attended five nightclubs, caused 50+ new infections’

Hong Kong: ‘106 cases linked back to exposures from staff & musicians at bars.. 73 of the people in this cluster caught virus at the bars, 39 were customers vox.com/21296067/coron…

[Thread] So why does ventilation matter so much in #Covid19 suppression?

Covid-19 is a disease caught by inhaling virus particles in the air 1/
the closer you are to an infected person & the longer you spend, the higher the risk of inhaling infected air

Shouting, singing & exercising make it worse

[there’s very low risk of catching it from surfaces, early research was over-stated & hasn’t been repeated in labs] 2/
outdoors the virus is diluted & dispersed in the air, so the risks are very low (except up close conversation)

If we all lived outdoors there would be no pandemic, as the virus couldn’t reproduce enough, & would die out 3/

[Thread] Nursing Homes

‘103 #Covid19 deaths in October, 39 of them in nursing homes’

.. almost 40% of all recent deaths from #Covid19, & almost 1/2 of all deaths in Ireland since start of pandemic, are in #nursinghomes 1/ irishtimes.com/news/health/co…
about 30,000 people live in nursing homes... so just 0.5% of the population have suffered 50% of #Covid19 fatalities

HSE attribute this to ‘high rates of community transmission’, but... 2/ irishtimes.com/news/ireland/i…
..elderly people & people with health conditions who live ~outside~ nursing homes ‘in the community’ do not have these infection rates

... & Dublin #nursinghomes have not allowed visitors for more than 6 weeks now 3/

WHO warns of high risk of #Covid19 spread ‘especially indoors in poor ventilation’ & says ‘open a window’

.. so why no risk prevention advice in Ireland’s public health plan.. nine months after this was warned about in many other countries?
