However, both men and women, on average, each hand has 150 kinds of bacteria, many varieties have exceeded the expectations of the researchers. The study’s report was published in the Proceedings of the National Academy of Sciences. The researchers conducted a detailed examination of the hands of 51 college students, found a total of 4742 kinds of bacteria, on average, each hand has 150 kinds of bacteria, only 5 species in each detected palm, Hands are only 17% of the bacteria are the same.
While women in the hands of “master” more varieties of bacteria. The main is staphylococcus, E.coli.
How to do sanitizer?
1. Daily disinfection
People’s hands directly and frequently contact items, hand skin with bacteria, viruses and other microorganisms, of which the skin fold and fingertips on the most. These bacteria may not only make the body infected with their own disease, there may be by handshake, contact with other items such as telephone, door handles, etc., these bacteria spread to others.
The number and type of bacteria on a person’s hand is related to the exposed to the item, the degree of contamination, and cleaning habits.
In addition to a large number of human E. coli, there are Pseudomonas aeruginosa, Streptococcus, Mycobacterium tuberculosis and so on.
Besides, there are a variety of viruses, such as hepatitis virus, influenza virus, measles virus. By the correct way to wash, you can wash away 80% of the bacteria.
People in contact with bacteria and viruses before meals, do not wash their hands on food, will make bacteria and viruses through the mouth into the body, causing the spread of the disease. For example, patients with tuberculosis care, hand with tuberculosis bacteria, if not carefully wash their hands on food, they may be infected with tuberculosis, will also threaten the health of the common meal. Even if there is no direct contact with food, it is possible to spread the bacteria through the dishes and so on.

Especially in public places of the toilet, people in the “convenient” after hand contact with flush switches, door handles, stranded in these places the possibility of bacterial transmission disease is very large.
Li Ning, dean of Beijing Etiquette College, said research shows that the most important thing in personal hygiene is to develop the hygienic habit of washing hands before and after meals. A pair of uncleaned hands up to 800,000 bacteria, one gram of nail dirt in possession of 3.8 billion bacteria. Look at these amazing figures, we should be clear, do not wash their hands to eat is how susceptible to various intestinal infectious diseases, so some people will call dysentery “dirty hand.”
Li Ning, said: “Wash hands before and after meals from kindergarten began to instill common sense. But this simple health habits is not been well implemented. For example, when we eat together, a table to sit down and not a lot People who wash their hands, even those who wash their hands, will be ridiculed by others who do not.
“During the meal to go to the bathroom toilets, which will bring people to eat together with a strong sense of unsanitary. We know you are going to the toilet, so you come back to see you do not wash your hands, grabbed chopsticks eat together Dinner people will form a association that you pollute the food. This is in foreign affairs, business dinner which is taboo. “Li Ning, Dean said.
