Summary
A study found that poor air quality and close contact in classrooms may spread respiratory viruses like the flu this winter. Improving classroom ventilation could help reduce the spread of these viruses. Children and adults at risk may benefit from better air quality.
Key Facts
- The study was carried out by scientists at the University of Bern, Switzerland.
- The research observed 67 students aged 14-15 in a Swiss secondary school over six weeks.
- Students spent over 5 hours in shared spaces daily, with poor air quality noted for about 1.9 hours.
- The study revealed that virus transmission is more likely within classes rather than between different classes.
- Scientists recommend opening windows regularly and investing in better ventilation systems.
- Improving indoor air quality can help protect against viruses and support better learning environments.
- Influenza, RSV, and COVID are common respiratory viruses that can be severe for infants and older adults.
