To prevent exposure to dangerous viruses and bacteria many people use sanitizers such as Purex or Lysol. While hand sanitizers do get rid of some types of dangerous bacteria many types of viruses are untouched by such sanitisers. Hand sanitizer works by using a chemical to disinfect the surface it is applied to. ''Alcohol-based hand sanitizers are clearly a very useful and important method to prevent most bacterial and viral infections, with rare exceptions, Alcohol-based hand sanitizers are clearly a very useful and important method to prevent most bacterial and viral infections, with rare exceptions," says Aaron E.

Isopropyl Alcohol can kill 99.99% of all non-spore forming bacteria types in under 30 seconds. In a large clinical study in 2004 a test showed that placing hand sanitizer dispensers in an office resulted in a 21% reduction in absences. In schools the test showed 51% less of absences, and 43% in college dormitories. The standard for hand sanitisers used in clinics and hospitals is a alcohol concentration of at least 70% but in U.S. stores hand sanitisers that have as low as 40% concentrations are available. In the food industry workers are not allowed to use only alcohol antiseptics. Certain spore forming bacteria, especially the endospores of gram-positive bacteria are usually resistant to hand sanitizers as well as soap and water but are visible in spore formation. Gram positive bacteria is impenetrable to sanitizers because of its thick and well built plasma membrane which is thicker than most viruses and fungus cell’s membranes. This attribute gives great difficulty to alcohol antiseptics and is hard to destroy the proteins inside the cell because of the thick wall. Most alcohol based sanitizers are effective against most viruses and funguses better than simply hand washing with soap. Never the less it is good to wash your hands frequently and not rely solely on alcohol based hand sanitiser. By washing your hands with soap and warm water you are able to get rid of most of the bigger more visible funguses and
