A eureka moment from Irish architect Orla Hegarty who has found that half of all deaths from Covid in Ireland were infected in just 400 buildings.

• More than half of the people who died were infected in just 0.03% of buildings
• Over half of the cases in workplaces outbreaks have been in just 150 buildings
• Infection in overcrowded private homes is twice the rate of uncrowded homes
• 1 in 4 school buildings has had a Covid-19 index case in the last 4 months

Joint Oireachtas Committee on Health report: COVID-19 prevention is possible by managing people and managing indoor air

In Ireland half of the people who died from #Covid19 were infected in fewer than 400 buildings

Ireland has >2,500,000 buildings

Risk is about buildings, not behaviour

Spread is about clusters, not contacts

Control is about eliminating the hot spots (pic: @mdc_martinus ) pic.twitter.com/CKcVWYWAud
