New HKU5 coronavirus strain has not infected humans yet

"Although no outbreak of the HKU5-CoV-2 strain has been detected, preventive measures remain the same as for other respiratory viruses like influenza, Covid-19, or RSV. These include avoiding crowded places, wearing a mask when necessary or when experiencing respiratory symptoms to prevent transmission, and practicing regular hand hygiene. High-risk individuals prone to severe illness can receive vaccines, such as the influenza or Covid-19 vaccine."

Dr Opas added that research on new bat viruses in China, Japan, and the US is conducted as a preparedness measure, given the ongoing mutation of coronaviruses. Once a virus is discovered, its characteristics are studied to support vaccine development. The risk of direct bat-to-human transmission remains low to moderate, as bat viruses typically exist in small quantities, human exposure to bats is rare, and transmission often requires an intermediate host.
