Crosslandkelly,if the person infected used the toilet they would flush the chain , after use touch the door handle and lock, so any of these surfaces could be contaminated with urine/feaces and or blood the person entering after them could have a cut on there hand,however small a risk is there. They could sneeze on the plane all these things are body fluids and its these fluids that spread the virus, call me overeacting but if id been on that plane id be worried. But id never be on that plane myself as i have no desire to put myself and the rest of the population here at risk on my return.mountainm care to comment on my more clarified posts on page 4?
