The vast majority of bacteria, microbes and viruses entering our bodies have a very short-lived existence. They are immediately picked up by the immune system, which sends its killer cells to deal with the problem. Only highly-adapted, very tough bugs endure, such as MRSA and HIV. Common ones die off within a few day... |
