Can norovirus be aerosolized? Researchers use vomiting machine to find out

Researchers used a unique approach to study if norovirus — the leading cause of acute gastroenteritis worldwide — can become aerosolized: They built a vomiting machine to mimic how humans vomit.

According to an NPR report, a civil engineer built a vomiting device based on what is known about the pressure and volume that happens when a human throws up. Then, researchers encased the device in a Plexiglas box and experimented with it using a stand-in for norovirus, a bacteriophage.

They found that some virus particles did aerosolize during vomiting, enough that it could spread the illness to others.

The researchers published the results in PLOS ONE.

At the Becker's 11th Annual IT + Revenue Cycle Conference: The Future of AI & Digital Health, taking place September 14–17 in Chicago, healthcare executives and digital leaders from across the country will come together to explore how AI, interoperability, cybersecurity, and revenue cycle innovation are transforming care delivery, strengthening financial performance, and driving the next era of digital health.
