Since then, World Handwashing Day aims to extend the best hygiene practices to the entire planet. The practice of washing your hands is common in most parts of the world, but soap is rarely used after critical moments (after using the toilet, cleaning a child’s stool or before handling food).

Handwashing with soap is one of the most effective and economical ways to prevent diarrheal and respiratory diseases, which are responsible for ensuring that every year more than 3 million children do not reach 5 years of life. Every 20 seconds, a child dies as a result of poor sanitation, that means 1.5 million deaths a year that could be prevented. According to WHO, washing hands with soap and water would reduce the risk of acute diarrheal diseases by 47 percent.

Incorporating the practice of handwashing with soap in every home in the world could save more lives than any medical intervention. Declaring October 15 as World Handwashing Day also has as another key objective to ensure access to sanitation and drinking water sources throughout the world.

A gesture as simple as washing your hands with soap and water can be key to the survival of millions of people, especially the little ones. Children are especially vulnerable to the effects of diarrhea and respiratory infections, diseases that can be easily and cheaply prevented with a little soap and water. This day wants to serve as a reminder of the importance of this practice.

Equitable access to hygiene facilities that allow us to wash our hands with soap helps us build a better future as we move towards achieving the Sustainable Development Goals.

Today we celebrate World Handwashing Day, but it is a call to practice it every day; We have a great challenge in converting an idea that is often abstract in an internalized and conscious behavior in homes, schools and communities around the world.

Aspects we should all know about hand washing

Washing your hands only with water is not enough, it is a widespread practice worldwide, but it is much less effective than doing so using soap. The soap favors rubbing, gives off a smell and produces a pleasant sensation that encourages its use.

Different medical studies have confirmed that washing your hands with soap is an effective way to prevent disease transmission even in impoverished settlements with high levels of pollution. Skin or eye infections, intestinal parasites, different types of flu and even a health improvement for people with HIV / AIDS are possible with proper hand washing.

There are critical times of the day when it is mandatory to wash your hands with soap: after using the bathroom, when coming into contact with feces or before handling food. The hands are the main carriers of germs that cause disease.

Washing your hands is the most effective and cheap health or hygiene intervention in the world.

A final key aspect of World Handwashing Day is to turn children into “handwash ambassadors” nationwide in all countries. Involving children in these activities can be a real factor of change to absolutely establish this practice worldwide.

1. The hand disinfection effect should meet the following requirements:

a) Sanitary hand cleaning, the total number of bacterial colonies monitored should be ≤10cfu/cm2

b) Surgical hand disinfection, the total number of bacterial colonies monitored should be ≤ 5cfu/cm2

2. Concept of sanitary hand disinfection and surgical hand disinfection

a) What is hygienic hand disinfection? Refers to the medical staff using quick-drying hand disinfectant to rub both hands to reduce the process of temporary hand-dwelling bacteria.

b) Surgical hand disinfection? Before the operation, the medical staff washes the hands with soap (soap) and running water, and then removes or kills the temporary bacteria and reduces the resident bacteria by hand disinfectant. The hand sanitizer used can have sustained antibacterial activity.

3. Hand washing and sanitation hand disinfection should follow the following principles:

a) Wash hands with soap (soap) and running water when there is visible contamination of the hands such as blood or other body fluids.

b) When there is no visible contamination of the hand, it is advisable to use a quick-drying hand disinfectant to disinfect the hands instead of washing hands.

4. Medical staff should wash their hands first in the following situations, and then disinfect the hands:

a) After contact with the patient’s blood, body fluids and secretions, and items contaminated with infectious pathogenic microorganisms.

b) After directly inspecting, treating, caring for or treating the infected patient’s dirt.

5. Hand hygiene monitoring sampling time and method:

a) Sampling time is sampled before contacting the patient and conducting a diagnosis and treatment activity.

b) Sampling method The subject is close to the fingers, and the cotton swab soaked with the sterile eluate containing the corresponding neutralizing agent is rubbed twice from the finger to the fingertip on the double-finger surface, one hand is coated. The rubbing area is about 30cm2, and the cotton swab is rotated at the same time during the rubbing process; the cotton swab is cut off from the operator’s part, and 10 ml of the sterile eluent test tube containing the corresponding neutralizing agent is put into the test tube, and the test is promptly sent.

Hand hygiene and effect monitoring analysis

There is no standard for monitoring the total number of bacterial colonies after washing hands in the “Health Code for Medical Staff Hand”.

In the Prevention and Control of Infection in Primary Care Institutions, the advantage of hand disinfectant is that it can kill potential pathogens more effectively than running water soap. The monitoring shows that the bacterial count is significantly reduced, and the time required is shorter and more convenient. Liquid and running water can improve skin allergies and dryness. Frequent hand washing and hand disinfection can cause skin damage. The hand washing effect is better than the hand sanitization effect, and the hand disinfection effect monitoring is superior to the hand washing effect.

Based on the above analysis, there is no monitoring standard for running water washing national regulations, and there are monitoring standards for hand disinfection regulations. At the same time, in order to increase hand hygiene compliance and ensure hand hygiene, there is no visible pollution in the hands (except for C. difficile infection). It is recommended to use hand sanitizer for hand hygiene.

Although the hand hygiene effect monitoring after washing hands is not routinely carried out, it is possible to check from time to time to understand the effect of washing hands and the contamination of hand washing water. Therefore, it is not recommended to routinely monitor the hand hygiene after washing hands.

With this action, which does not take more than a minute, intrahospital infections can be reduced by up to 50%, the spread of existing bacteria in the environment is prevented and the early recovery of hospitalized patients and people with Acute Respiratory Infections is contributed (GO TO).

As explained by the Department of Epidemiology and Prevention of Infectious Diseases of the Central Military Hospital, washing your hands at the right time can save lives. This is confirmed by the World Health Organization -OMS-, which ensures in recent years, this measure in health care has saved the lives of millions of people.

Through the Hand Hygiene Program of the Epidemiology Service of the Central Military Hospital, in the course of 2019 it has been possible to impact more than 1,500 people during the awareness sessions on handwashing. The first was from March 26 to April 9 and the second was held on May 2 and 3.

“Everything we interact with every day is full of bacteria, a cell phone, for example, has 30 times more bacteria than a toilet, there are bacteria, viruses and disease-causing parasites,” said the pediatric infectologist in a release.

In the framework of the World Handwashing Day, which is celebrated on October 15, the specialist said that people are in daily contact with objects such as computer keyboards, ATMs, coins and bills, among other objects that are incubators of bacteria

“These can endanger our health if we do not have a proper cleaning habit in our hands. In fact, in one hand they have been able to identify between 104 and 109 different types of bacteria,” he said.

Children, especially when having outdoor activities, contact with animals, toys and other things have a higher risk of getting an infection such as diarrhea, which can be complicated due to dehydration.

“When a person does not wash their hands with soap and water, they can transmit bacteria, parasites and viruses, either by direct contact, that is, by touching another person, or indirectly, by touching surfaces,” he added.

That is why he asked for extreme care, washing his hands for at least a minute so that washing is efficient and reducing the risk of gastrointestinal diseases and doing it before, during and after preparing food, caring for someone sick, going to the bathroom, changing diapers , sneeze and touch pets.

“If, despite washing our hands, we notice some type of infection, it is important to see a doctor as this is the best way to identify the cause of our problem and determine the best treatment to solve it,” Morayta Ramírez concluded.

So, which of the gloves and automatic sensor sterilizer is more conducive to food safety?

Wearing gloves for food production and processing seems to have become a symbol of food safety, but in fact, this sense of security is only a false indication of the surface. Even better gloves are not likely to replace regular, thorough hand washing. Wearing gloves does not adequately prevent food contamination when processing direct foods. Conversely, because the wrong psychological cues may encourage some of the risky behavior of the operator to cause unforeseen risks.

For food practitioners, hand disinfection is a simple and negligible link that is largely ignored. There are many opportunities for bacteria, viruses, and dirt to come into contact with the outside world, and it is easy to be soiled. There are about 800,000 bacteria in a pair of unwashed hands. If the first hand disinfection is not complete, or if the hands are re-sterilized by the second hand disinfection within 60 to 90 minutes, even if the previously sterilized food is easily contaminated by the hand bacteria, the food will be cross-contaminated for the future. Mildew leaves a hidden danger.

Enterprises should establish a sanitation and disinfection procedure for “automatic hand washing, automatic hand drying, automatic disinfection”, and implement “GMP”, “SSOP”, “HACCP” and “QS” hygiene procedures, if each key position requires hand disinfection. Install an automatic sensor hand sterilizer, which meets the standard requirements, saves a lot of disinfectant, improves work efficiency, avoids secondary pollution before and after disinfection, and quickly kills hand bacteria, and calculates the time after the first sterilization. The hands are re-sterilized every 60 to 90 minutes to block the growth and reproduction of the bacteria in the hands.

After installing the automatic sensor hand sterilizer, if 75% medical alcohol is used as the disinfection medium, the process is: “Induction soap machine hand washing – faucet washing – inductive drying – inductive hand disinfection”; using other disinfectant as the disinfecting medium : “Induction of soap machine washing hands – faucet washing – inductive hand disinfection – inductive drying”; it is recommended to choose the previous method, because there is no residue in the hands after the alcohol is volatilized.

The warm, humid environment of the gloves is an ideal place for microbial reproduction. Different brands of gloves have different materials and the probability of cracking is different. For example, vinyl gloves are more likely to tear than latex, and another threat is that long nails or rings greatly increase the puncture gloves. Bacteria can spread even in tiny holes or through sweat. Harmful bacteria that spread from nails and jewelry are more concentrated than direct hands. Put on the gloves and repeat the timed disinfection. How many manufacturers can do it?

From the above argumentation, we can get a very good conclusion: while improving the work efficiency, the hand sterilizer also avoids the secondary pollution before and after disinfection, and achieves the effect of quickly killing the bacteria in the hand. Even better gloves are not likely to replace regular and thorough hand washing.
