For example, cramped and badly ventilated living quarters and exposure to particulate pollution such as dust, sand, pollen, cooking fires, and habitual smoking have all been discussed as causative factors in relation to the presence of IPR in different archeological settings, and high population density also predisposes to the ready transmission of lower respiratory tract diseases (Binder, , pp. 303–305; Capasso, ; Lambert, ; Pfeiffer, ; Roberts, ; Walker & Henderson, ).…”
