Abstract: Protection from germs, viruses and other infections,Dispensers/or Attachments, containing disinfecting properties, are secured or attached to door handles, and other, touched by public's hands. This safe form may be in caplets releasing a light, odourless mist; a gentle spray; or can be a dry form in a packet, or long 'ribbon' pouch, adhering holder. Latter might be put around a medical garbage container. The small style of disinfectant pouch, can be taped inside a pocket, and when soiled hands are in the pocket, they get released upon, a dry, disinfectant, through a light mesh. The latter are useful also taped to a paper bag at hospital beds. As well, inside salon workers might have a couple of packets taped to their capes. Outside workers can have this protective packet taped to a scarf or other, in 'colds' season.   If it is a disinfecting cashier-'shield', other method of releasing, on occasion, can be by manually pressing a button to an attached disinfectant-dispenser. When it is at automatically-opening doors, or elevator doors, the mist can emanate from a floor mat, or device attached to solid structure. Another method of use is more mechanized, if a separately attached wall dispenser, across the handle/knob of door, automatically sprays disinfectant, when door is opened. Toilet tank handles should have disinfecting, attachment/dispenser to benefit next user's hands. This also would be protective on latches to stalls.
