Airport Disease Scanner in which we scan humans on airports for viruses DNA basically this detect viruses DNA in a human body. In that scanner we already store human DNA structure and it will detect any new DNA structure on human body or in human body so we will able to quarantine the person and prevent the spread of virus in the world. We will install it in airports like metal detectors so it will scan human body DNA.
