♦ Scientists from the London School of Hygiene & Tropical Medicine and Durham University collaborated on the study.
♦ They believe that dog screening and swab testing can detect 91% of infections.
♦ They report that dogs can detect the virus in a few seconds. The traditional COVID test takes 15 minutes to get results. Therefore, in one and a half hours, dogs can screen 300 people together.
♦ Therefore, sniffing testing may be a suitable method for large-scale screening.
