∙ 16y agoBacteria can infect your body and destroy your cells. Not all bacteria is good. Viruses and diseases essentially arise from bacteria. Wash your hands frequently and keep clean. Do not come in direct contact with everyone. Do not touch everything you see around you in a public place. Do not share drinks and food with people. Practice abstinance. Don't sneeze in your hands. Sneeze into the crook of your arm. Wash fruit before you eat them. However, don't overdo it because it will reduce your immunity.
