This clear and accessible 2026 guide from Let’sAir explains how respiratory infections such as COVID-19, influenza, measles, tuberculosis and RSV can spread through the air we breathe. It explores airborne transmission, infectious particles, ventilation, CO₂ monitoring, and practical ways to reduce infection risks — helping to make the science of safe air easier to understand.
The guide also highlights the importance of indoor air quality and practical mitigation measures, reinforcing why clean air, ventilation, filtration and monitoring should be considered key public health tools in reducing the spread of infectious diseases.
