09 a bar of soap transmit infection?
Are there any health risks to using a communal bar of soap? No. Bar soap does not appear to transmit diseases. The most rigorous study of this question was published in 1965.
Scientists conducted a series of experiments in which they intentionally contaminated their hands with about five billion bacteria. The bacteria were disease-causing strains, such as Staphylococcus and E. coli. The scientists then washed their hands with a bar of soap and had a second person wash with the same bar of soap. They found that bacteria were not transferred to the second user.
The Center for Disease Control and Prevention recommends hand washing with soap as the primary defence against infection and gives the same approval to bar soap as it does to liquid soap. Therefore, the only mistake one could make would be not to wash one’s hands because of an unfounded fear of contamination.
