It’s time to rethink indoor airflow to reduce the spread of COVID-19, say experts

Masks, social distancing and hand hygiene have become widely accepted as ways to reduce the spread of coronavirus but some scientists are saying the ventilation of our homes and workplaces could be another tool in our prevention armoury.

As we learn more about COVID-19, more evidence has emerged that the virus spreads through aerosols as well as through larger droplets, especially in closed, crowded spaces.

But the good news, according to aerosol scientist Alex Huffman from Denver University, is we can do things to reduce the risks indoors.

“Ventilation is a really important piece of the puzzle,” he told the ABC’s AM program.

Keeping fresh air flowing has not yet been a high priority as public health officials have focused on the important work of increasing the adoption of social distancing and mask-wearing but now, said Dr Huffman, it was time to begin talking to the public more about our indoor environment.

Some solutions, he said, could be implemented by people in their own homes at little to no cost but making changes to offices and public buildings needed a bigger effort from politicians and business.

“It is a resource issue but I also think it’s a leadership issue. If your leaders are convinced that this is a critical piece of the puzzle, then they will find a way to make it happen.”
