It's #airborne! '#SARSCoV2 is largely transmitted in airborne fashion via #aerosols, which people exhale, and which can remain in the air for long periods of time if a room is not well-ventilated.'

Has the UK government ensured that our schools are ready?

'Open windows and a good heating, ventilation, and air conditioning (HVAC) system are starting points for keeping classrooms safe during the Covid-19 pandemic.'

'But they are not the last word, according to a new study from researchers at MIT.' @MIT

'Study, @MIT, shows how specific classroom configurations may affect air quality and necessitate additional measures, beyond HVAC use or open windows, to reduce the spread of aerosols, those tiny, potentially Covid-carrying particles that can stay suspended in the air for hours.'

'Patterns of SARS-CoV-2 aerosol spread in typical classrooms...' sciencedirect.com/science/articl…

'Current industry guidelines to control the spread of aerosols such as #SARSCoV2 have adopted a six-foot (~1.8 m) spacing between individuals indoors, recent evidence suggests that longer range spread is also responsible for infections in public spaces.'

Conclusions:

'#COVID-19 is an #aerosolized #virus. With such small particle sizes, the established six-foot (~1.8 m) spacing guidelines and heightened air change rates are an incomplete picture.'

'More work is necessary to determine the impact of increased #ventilation on air flow patterns, the threshold for infection by #aerosols, and to enhance the removal of aerosols through the design of the airflow within an occupied space.'

#Covid19 science. In the UK there's been, for some reason, a failure to recognise the importance of fluid dynamics, airflow rates, the level of aerosol produced by infected individuals, alongside a consideration of basic 'surface science'.

Misjudgement.
