A new study by scientists at the University of Toronto (Toronto) analyzed the factors that affect the transmission range of influenza virus aerosols, thereby trying to assess how far away from an infected person can stay healthy. Previous research has shown that breathing is the main way in which people are exposed to viral particles, but no one knows how far they fly.

The study, published this week in Scientific Reports , is the first to track the movement of virus particles through indoor spaces. Scientists have studied this phenomenon for years, trying to determine how far viruses can travel through air and at what concentrations they are there. A few studies have investigated the issue with experimental chambers or simulations under different circumstances, but none have been conducted in actual homes.

Moreover, scientists have used different types of viruses for this type of research, so the results do not necessarily apply to all viruses. In fact, there has been a growing realization that influenza may behave quite differently from other respiratory viruses and produce particles that fly farther and stay in the air longer than other viruses.

The starting point of the study by scientists at Toronto was to observe how flu behaves in people's homes, which is precisely what led them to conduct this research. The team analyzed nine homes with different layouts and ventilation systems. They found that airborne influenza virus concentrations were actually quite similar to those reported for other aerosol-borne viruses (such as those that cause the common cold). In addition, they found that homes have a mix of "hot spots" and "cold spots" for influenza virus.

Hot spots are particularly interesting to researchers because these were where concentrations peaked and remained high. They also learned about the role played by airflow patterns: Generally speaking, a home with forced-air heating or air conditioning experienced more movement and mixing of air throughout the house. This suggests that, in general, homes with forced-air ventilation may produce more variability in exposure than those without such systems. Finally, they found that younger people were at greater risk than older individuals because they spend more time closer to the ground where concentrations are higher due to the influence of gravity.

All these factors are associated with the risk of infection, but to discover how they interact requires more research, especially since some homes have several risk factors simultaneously present. While it is difficult to generalize the results - given that eight homes were studied in detail and their surroundings are different from one another - the study provides guidelines for future studies that investigate the risk of infection.
