Dozens of the world's top experts in how diseases spread have called for big improvements to the air in buildings.
They say current rules on ventilation are failing to stop infections, including Covid-19.
The problem is likened to the health crisis caused by contaminated water in Britain's cities in the 1800s.
The appeal comes amid growing evidence that the coronavirus is often transmitted via infectious aerosols in crowded indoor spaces.
Writing in the journal Science, the scientists and engineers say that while governments have regulations on the safety of food, sanitation and drinking water, there's far less emphasis on pathogens in the air.
