Using UV light for disinfection is common in medicine, but a Nova Scotia doctor is exploring a new application of the practice. With funding from Research Nova Scotia, Dr. Kenneth Rockwood is studying whether UV lights mounted in the ceiling of long-term care homes can kill airborne viruses and reduce infections. "This is an important problem because even before the pandemic, it was a very common cause of death," said Rockwood, a geriatrician with Nova Scotia Health.
