And in fact, many microbes actually help animals thrive and survive, according to studies examining germ-free mice, Helen Vuong, a postdoctoral scholar of Integrative Biology and Physiology at the University of California, Los Angeles wrote in The Conversation. That hydrophobic tail has an affinity for fats, and all bacteria and some viruses — including SARS-CoV-2, the coronavirus that causes the disease COVID-19 — have a lipid membrane, which leaves it vulnerable to a soap molecule's fat-puncturing tail. Soap molecules are so effective at eliminating and annihilating the germs on our hands that antibacterial soap is completely unnecessary and can be harmful; by driving the evolution of antibiotic-resistant strains of bacteria, Swartzberg said. Bacteria or viruses are easily captured by micelles because the outside of the micelle is hydrophilic, so it's easily swept off your hands and down the drain — along with its pathogenic prisoners — when you rinse the soap away with water. Not really, said Emily Sickbert-Bennett, director of the University of North Carolina (UNC) Medical Center's Infection Prevention program and associate professor of epidemiology and infectious diseases at the UNC School of Medicine. The COVID-19 bugs, for example, need to be transferred while intact into a person's respiratory system or eyes, so by washing hands before touching the nose, mouth or eyes — the chain of transmission for COVID-19 is broken. "Surfaces can be disinfected with everyday household wipes or sprays, and that certainly eliminates the microbes that are found on those surfaces," she said, but those surfaces tend to become continuously recontaminated. These more problematic microbes are likely what most people are worried about when they're trying to get rid of "germs." So, is there any hope for keeping our environments clear of these microscopic bad guys? In fact, most of them are innocuous unless
