How long does hiv virus live outside body virus?

Varies a lot: A great source of info is at https://www.canada.ca/en/public-health/services/laboratory-biosafety-biosecurity/pathogen-safety-data-sheets-risk-assessment/human-immunodeficiency-virus.html, which says that survival is more than one week if HIV in blood serum is just left to dry on a glass slide. Of course, we commoners don't have glass slides at home.
