Amazon is continuing to integrate AI into its online shopping experience. On Wednesday, the retail giant announced that customers in the US will see AI-generated images when they type product terms into the search bar. But these pictures are not of real-life, non-AI products available for purchase. Instead, they're meant to illustrate concepts and hone customer searches.

Researchers traced a COVID-19 outbreak to a shared ventilation system in a multifamily building By Kristen Dalli of ConsumerAffairs June 3, 2026


A new study suggests airborne viruses can move between some apartments through shared bathroom ventilation systems.

Researchers investigated a COVID-19 outbreak in a Spanish apartment building and found ventilation ducts were the most likely transmission route.

The findings highlight the importance of building ventilation and indoor air quality in multifamily housing.

A study published in PLOS One examined a COVID-19 outbreak that occurred in a seven-story apartment building in Santander, Spain, during the early months of the pandemic. Researchers found evidence suggesting the virus likely spread between apartments through a shared bathroom ventilation system rather than through direct contact between residents.

The findings add to growing research showing that airborne viruses can move through connected indoor spaces. While the study focused on one specific building design, it offers new insight into how ventilation systems may influence the spread of infectious diseases in multifamily housing.

We tend to think that if we shut the door in our apartment, we are safe and cant get infected. But our study shows that, depending on the ventilation system in place, that may not be the case, senior author Shelly Miller said in a news release.
The study

The outbreak occurred in June 2020 when 15 residents living in four vertically stacked apartments became infected with COVID-19.

To understand how the virus spread, researchers analyzed epidemiological data, genetically sequenced virus samples, measured airflow and air pressure within the building, and used computer simulations to model the movement of airborne particles.

The building used a shared vertical bathroom ventilation shaft, a design common in many older buildings in Spain. Unlike modern systems that rely on mechanical fans, these ducts use natural airflow to move air upward and out of the building.
The findings

Researchers discovered that weather conditions could sometimes reverse airflow within the shaft, pushing air back into apartments. They also found that running a kitchen exhaust hood could increase air movement between units.

In one experiment, elevated carbon dioxide levels were detected inside a vacant apartment, suggesting that air from occupied units was entering the space.
