Survival of influenza virus on human fingers Y. Thomas, P. Boquete-Suter, D. Koch, D. Pittet, L.

FIG. 1 Fingers contaminated with a 2-μL drop of viral suspension mixed in human respiratory secretion. Clinical Microbiology and Infection 2014 20, O58-O64DOI: (10.1111/1469-0691.12324) Copyright © 2014 European Society of Clinical Infectious Diseases Terms and Conditions

FIG. 2 Influenza A (H3N2) and A (H1N1) 2009 viral survival on fingers over time (X axis). Bars (left scale) and lines (right scale) represent the absolute number of fingers and individuals, respectively, from whom infectious virus was recovered.

FIG. 3 Influenza A (H3N2) viral survival on fingers according to the volume of the contaminated droplet. Four individuals (three fingers each) participated in this experiment, in which viral concentration was fixed. The number of fingers (bars) and individuals (curves) from whom infectious virus could be isolated after 15 min is represented according to the volume of the contaminated droplet (X axis).

FIG. 4 Influenza A (H3N2) viral survival on fingers according to volume and concentration of the contaminated droplet, each containing the same number of infectious viral particles. Six individuals (three fingers each) participated in this experiment. The number of fingers (bars) and individuals (curves) from whom infectious virus could be isolated after 15 min is represented according to the volume and the viral concentration of the contaminated droplet (X axis).

FIG. 5 Impact of mechanical constraint on viral survival. (a) 2 μL of viral inoculum remained intact (black bars and diamonds in c and d) or (b) was disrupted immediately after deposition on fingers (white bars and diamonds in c and d). Survival of infectious viruses was evaluated by the number of fingers (bars) and individuals (diamonds) where infectious virus could be isolated 1 min and 5 min after deposition of influenza A (H3N2) (c) and A (H1N1) 2009 viral suspensions (d).
