It is commonly accepted that at between 1 million to 1 billion bacteria are needed to cause infection although some investigators suggest some people may be infected by far fewer bacteria. Nevertheless, most data suggest food, water, or other sources of contamination contain large amounts of bacteria.
Burton, M. и др. The effect of handwashing with water or soap on bacterial contamination of hands. // Int J Environ Res Public Health 8 (1). 6 януари 2011. PMID 21318017. с. 97 – 104. Посетен на 5 юни 2011. Bacteria of potential faecal origin (mostly Enterococcus and Enterobacter spp.) were found after no handwashing in 44% of samples. Handwashing with water alone reduced the presence of bacteria to 23% (p < 0.001). Handwashing with plain soap and water reduced the presence of bacteria to 8% (comparison of both handwashing arms: p < 0.001).
