The expert advice is that super-spread events – where five people or more are infected – can be prevented, because 97 per cent of them happen indoors.
Many measures are simple and cheap: regular ‘airing out’ of rooms; resetting ventilation systems; checking wall vents are not blocked, and opening windows. Limiting activities such as shouting, singing and exercising indoors is also advised as is increasing humidity with humidifiers as the virus thrives on dry air.
Asst. Prof. Hegarty says vaccines alone will not end the pandemic.
“We now understand that risk of transmission is predominantly indoors and very specific to certain buildings and indoor air conditions.
“These conditions are preventable, and this knowledge is key to stopping infections and to opening buildings at low risk.”
