They say it can have consequences for the host nation and for people when they return to their own countries, A series of reports in The Lancet infectous disease journal have been highlighting the risks." this is what i have been saying for years about people spitting in the street, and coughing in my face or over the back of my neck, at car boots and other such places. am i the only one who uses a handkerchief(in my case a large bandana) or a tissue??
