Viral study on a ventilation filter from a public building

摘要

We read the recent article by Goyal et al1 reporting a viral study on a ventilation filter from a public building with great interest. The authors concluded that "existing building HVAC filters may be used as a method of detection for airborne viruses" and proposed that the assessement "can inform the development of methods to prevent airborne transmission of viruses and possible deterrents against the spread of bioterrorism agents." Indeed, the finding of virus m filters can be expected. Further investigations should address the possibility of spreading the virus to people in the building.
