Hand-to-hand transmission of herpes simplex virus type 1.
Droplets of tissue culture fluid containing herpes simplex virus type 1 were placed on the palm of the hand. Each 0.01 ml droplet was taken from a stock virus suspension with a titre of 10(7.5) TCID50/0.1 ml. At 0, 15, 30, 60 and 120 min a droplet was firmly touched with the middle finger of the right hand, after which, attempts were made to recover virus from the finger. At 0 min, when the virus-containing droplet was in a liquid state, there was a 100% rate of virus recovery. By 15 min the droplets had dried out, and after touching dried out droplets there was a 40% virus recovery rate, even though experimental procedures demonstrated that infectious virus was present in the dried out droplets at all test times. If the finger was moistened with tap water or saliva, there was a 100% recovery rate of virus after touching dried out droplets, as well as after touching droplets in a liquid state.
