Dr. Ignaz Semmelweis, a Hungarian physician, is credited with discovering the importance of handwashing in preventing the spread of germs in the 19th century. He observed that the incidence of puerperal fever (childbed fever) was significantly reduced when healthcare workers washed their hands with chlorinated lime solution.
The life span of germs on hands can vary depending on the type of germ and the conditions present. Generally, some germs can survive on hands for a few hours up to a few days. Regular handwashing with soap and water is important to reduce the transmission of germs.
Germs were first discovered in the 17th century by Antonie van Leeuwenhoek, a Dutch scientist, who observed microorganisms through a microscope. This discovery revolutionized our understanding of infectious diseases and laid the foundation for modern microbiology.
Germs form when bacteria, viruses, fungi, or other microorganisms enter the body through various means such as contact with contaminated surfaces, inhalation, or ingestion. These germs then have the potential to multiply and cause infections or illnesses.

Germs exist as part of the natural world and they play a role in various ecosystems. Some germs can cause diseases in humans and animals, while others are necessary for our health. Germs are constantly evolving and adapting to survive in different environments.
As soon as germs were discovered in the late 18th century people began washing their hands more often.
Germs can stay alive in air for up to 48 hours after leaving an infected person or animal. Some germs can live up to a week on surfaces they infect. It is best to keep hands washed, and surfaces sterile to kill germs.
More germs are in the hair than hands!
From dirty things, direct contact(from other people) and others.
A person has more germs in their mouth than on their hands. Saliva has enzymes that prevent germs from forming, while your hands touch things such as doorknobs all day which are infested with germs.
The germs on your hands will spread to every surface you touch. So the door handle in the bathroom will be full of germs. Any one who touches it after that will take some of the germs with them. everything they touch will also leave some germs behind. Also if you touch someone else you will pass germs to them as well.

Germs can survive on hands for varying lengths of time, depending on the type of microorganism and environmental conditions. Bacteria can typically live on skin for several hours to days, while viruses may survive from a few hours to several days. Factors such as moisture, temperature, and surface type also influence their longevity. Regular handwashing with soap and water or using hand sanitizer can effectively reduce the presence of germs on hands.
