did you read the post? OP is describing shit flowing down the street. You seem to be under the FALSE impression this is mainly dangerous if it gets in a wound. Not at all considering what if it gets into the digestive system to name but one other point of entry. Try reading the first few paragraphs of https://en.wikipedia.org/wiki/WASH and skimming around. I don’t see a lot of “germ phobia” being discussed here.
sewers fecal matter had overflown onto the road
this is critically dangerous which will certainly result in extreme illness in the neighborhood. People die from these kinds of situations. They tend not to be accompanied by robust health systems or other supports. There has obviously been neglect / catastrophe on the public health front.
Your advice is patronizing, inane, ignorant… and dangerous.
NO if you were describing your situation even half-way accurately, the above comment is DANGEROUS.
