When was hand hygiene discovered?
1847It was a doodle of Ignaz Semmelweis, a 19th-century Hungarian doctor who was known as the pioneer of hand-washing. He discovered the wonders of the now-basic hygienic practice as a way to stop the spread of infection in 1847, during an experiment in a Vienna hospital's maternity ward.
Who introduced the concept of hand hygiene?
SemmelweisSemmelweis is considered not only the father of hand hygiene, but his intervention is also a model of epidemiologically driven strategies to prevent infection.
When did nurses start washing their hands?
During the Crimean War (1853-1856) Nightingale had implemented hand washing and other hygiene practices in British army hospitals. This was relatively new advice, first publicised by Hungarian doctor Ignaz Semmelweis in the 1840s, who had observed the dramatic difference it made to death rates on maternity wards.
Who first discovered the importance of hand washing before and after surgery?
Dana Tulodziecki, a philosophy professor in the College of Liberal Arts, has written about how scientific thought radically changed in the 19th century regarding the spread of diseases and how one Hungarian obstetrician, Ignaz Semmelweis, was credited with discovering hand-washing as a way to reduce the prevalence of a ...
Who invented the 5 moments of hand hygiene?
the World Health OrganizationThe 5 Moments for Hand Hygiene approach was designed by the World Health Organization to minimise the risk of transmission of microorganisms between a healthcare worker, the patient, and the environment.
Who discovered that washing hands saved lives?
Ignaz SemmelweisThe physician who discovered that doctors could save patients' lives simply by washing their hands. It is 1847 and the death rate among pregnant women in the obstetric clinics where physician Ignaz Semmelweis works is high.
Why did doctors not wash their hands?
However, the innovation was not popular with everyone: some doctors were disgruntled that Semmelweis was implying that they were to blame for the deaths and they stopped washing their hands, arguing in support of the prevailing notion at that time that water was the potential cause of disease.
How did people clean before soap?
Not even the Greeks and Romans, who pioneered running water and public baths, used soap to clean their bodies. Instead, men and women immersed themselves in water baths and then smeared their bodies with scented olive oils. They used a metal or reed scraper called a strigil to remove any remaining oil or grime.
Why did doctors start washing their hands?
It wasn't until the mid-19th century that doctors realized going straight from an autopsy to the maternity ward was not a good idea. One of the best ways to prevent the spread of the flu and other viruses is to wash your hands.
What is the history of hand-washing?
Medical hand-washing became mandatory long after Hungarian physician Ignaz Semmelweis discovered its effectiveness (in 1846) in preventing disease in a hospital environment. There are electronic devices that provide feedback to remind hospital staff to wash their hands when they forget.

How many new mothers died from puerperal fever?
There, according to a history of hand hygiene published by the World Health Organization, Semmelweis found that 7 percent of new mothers died from the fever, compared with 16 percent in the doctor-led clinics. In the 1840s, the time after childbirth was dangerous for mothers, who often contracted puerperal fever.
What changed the way people thought about hygiene?
As doctors grappled with childbed fever and scientists developed new ways of understanding disease, cultural developments also changed the way people thought about hygiene, Ward says. The work of Semmelweis, Pasteur, and others was simultaneous with the rise of Big Soap.
How many maternity clinics were there in Vienna in the 1840s?
The Vienna General Hospital had three maternity clinics operating in the 1840s. One was staffed by midwives. The other two were run by physicians.
What were the factors that contributed to the rise of handwashing?
Cadavers, childbirth, and the rise of the Soap Industrial Complex all played a part in getting handwashing to catch on.
Why did soap manufacturers shout louder than doctors?
“The soap manufacturers were zealous in promoting their products,” Ward says. “They shouted it a lot louder than the doctors did because they wanted to sell. ”.
What was the period after childbirth in the 1840s?
In the maternity ward of the Vienna General Hospital in the 1840s, the period after childbirth was a particularly fraught time. To put it bluntly: Women were dying in droves. Regardless of their social status or how healthy they were to begin with, mothers who had recently had babies often developed a rapid heart rate, fever, shivering, and extraordinary abdominal pain that was often followed by death.
What did Semmelweis discover about the maternity ward?
In 1846, Semmelweis realized that the women giving birth in the medical student/doctor-run maternity ward were much more likely to develop “childbed fever” (now known as streptococcal infection), and die compared to the women giving birth in the adjacent midwife-run maternity ward. He decided to investigate, seeking differences between the two wards. In the end the death of his colleague Jakob Kolletschka in 1847 led him to a breakthrough.
Why did Kolletschka die?
Semmelweis theorized that his colleague died because “cadaveric matter” had entered his body through his wound, and wondered whether a similar type of infection could be happening in the doctors’ maternity ward.
Who promoted hand hygiene?
Sadly, the hand hygiene practices promoted by Semmelweis and Nightingale were not widely adopted. Only when scientists like Pasteur and Koch started to realize that certain diseases and infections are caused by certain microorganisms, the importance of hand washing as a critical hygienic practice took hold in the medical world. For example, the British surgeon Joseph Lister drastically improved patient mortality by advocating that surgeons wash their hands and sterilize their instruments in between patients.
Did Semmelweis change the rule that doctors wash their hands with lime after autopsies?
Semmelweis now imposed a new rule mandating that doctors wash their hands with chlorinated lime after autopsies. It was indeed a big improvement as between 1848 and 1859 the maternal mortality rate in the doctors’ ward dropped to around the same level as the midwives’ ward. This was the first proof that cleansing hands could prevent infection.
Did Louis Pasteur and Robert Koch make disinfecting hands in lime?
Unfortunately, the innovation was not very popular. Although he was able to prove his success epidemiologically, the causes of infections were still unknown. The idea that disinfecting hands in chlorinated lime would reduce the rate of infection simply did not fit in with the then current theory of miasmas and contagions. The result was hostility and exclusion. Only years later Louis Pasteur and Robert Koch laid the foundations for today’s microbiology.
Who was the first person to use handwashing?
A few years later, in the Crimean War (1853 to 1856), Florence Nightingale became another pioneer of handwashing. Her approach to caring for wounded soldiers and training nurses saved and improved countless lives. At a time when most people believed that infections were caused by foul odors called miasmas, Florence Nightingale implemented handwashing and other hygiene practices in the war hospital in which she worked. In her 1860 publication “ Notes on Nursing” she wrote that “Every nurse ought to be careful to wash her hands very frequently during the day.”
Is hand washing a good practice?
Today, medical and health professionals consider hand washing a critical hygienic practice, both for themselves and their patients. The fact that we now have a rich knowledge of hand hygiene and a range of hand disinfectants and test methods to prove their effectiveness and safety, is the result of the work of many researchers and developers. This knowledge forms the basis for finding solutions to current challenges like the outbreak of swine flu in 2009 and the current COVID-19 pandemic.
Why is hand hygiene important?
Hand hygiene is now regarded as one of the most important element of infection control activities. In the wake of the growing burden of health care associated infections (HCAIs), the increasing severity of illness and complexity of treatment, superimposed by multi-drug resistant (MDR) pathogen infections, health care practitioners (HCPs) are reversing back to the basics of infection preventions by simple measures like hand hygiene. This is because enough scientific evidence supports the observation that if properly implemented, hand hygiene alone can significantly reduce the risk of cross-transmission of infection in healthcare facilities (HCFs)1–5.
How effective is alcohol based hand wash?
One of the key elements in improving hand hygiene practice is the use of an alcohol based hand rub instead of washing with soap and water. An alcohol-based hand rub requires less time, is microbiologically more effective and is less irritating to skin than traditional hand washing with soap and water2,3,35. In the ICUs, switching to alcohol hand disinfection would decrease the time necessary for hand hygiene from 1.3 h (or 17% of total nursing time) to 0.3 h (or 4% of total nursing time)35,36.
What are the pathogens that can be found in the hands of HCWs?
The hands of HCWs are commonly colonized with pathogens like methicillin resistant S. aureus(MRSA), vancomycin resistant Enterococcus(VRE), MDR-Gram Negative bacteria (GNBs), Candida spp. and Clostridium difficle, which can survive for as long as 150 h. Approximately 106skin epithelial cells containing viable microorganisms are shed daily from the normal skin2,19, which can contaminate the gowns, bed linen, bedside furniture, and other objects in the patient's immediate environment. Hand carriage of resistant pathogens has repeatedly been shown to be associated with nosocomial infections1–3. The highest rates of hand contamination are reported from critical care areas, which also report most cases of cross-transmission. The hands may become contaminated by merely touching the patent's intact skin or inanimate objects in patients’ rooms or during the “clean” procedures like recording blood pressure1–3.
Why do microbes survive?
One of the reasons microbes have survived in nature is probably their simplicity: a simple genomic framework with genetic encryptation of basic survival strategies. To tackle these microbes, human beings will have to follow basic and simple protocols of infection prevention. The health care practitioners in our country need to brace themselves to inculcate the simple, basic and effective practice of hand hygiene in their daily patient care activities and serve as a role model for future generations of doctors, nurses and paramedical personnels.
When should HCWs clean their hands?
This approach encourages HCWs to clean their hands: before touching a patient, before clean/aseptic procedures, after body fluid exposure/risk, after touching a patient and after touching patient surroundings1,2. Other precautions in relation to hand sanitation.
What to do if you have Bacillus anthracisis?
Wash hands with soap and water when (i) visibly dirty or contaminated with proteinaceous material, blood, or other body fluids and if exposure to Bacillus anthracisis suspected or proven (since the physical action of washing and rinsing hands in such circumstances is recommended because alcohols, chlorhexidine, iodophors, and other antiseptic agents have poor activity against spores); (ii) After using a restroom, wash hands with a non-antimicrobial soap and water or with an antimicrobial soap and water; and (iii) before and after having food1–3,21–23,32.
What is the flora of the hands?

There are two types of microbes colonizing hands : the resident flora, which consists of microorganisms residing under the superficial cells of the stratum corneum and the transient flora, which colonizes the superficial layers of the skin, and is more amenable to removal by routine hand hygiene.
Why do we wash our hands?
Hand washing (or handwashing ), also known as hand hygiene, is the act of cleaning one's hands with soap and water to remove viruses / bacteria / microorganisms, dirt, grease, or other harmful and unwanted substances stuck to the hands. Drying of the washed hands is part of the process as wet and moist hands are more easily recontaminated. If soap and water are unavailable, hand sanitizer that is at least 60% ( v/v) alcohol in water can be used instead, unless hands are visibly excessively dirty or greasy. Hand hygiene is central to preventing the spread of infectious diseases in home and everyday life settings.
How does hand washing help?
Hand washing has many significant health benefits, including minimizing the spread of influenza, coronavirus, and other infectious diseases; preventing infectious causes of diarrhea; decreasing respiratory infections; and reducing infant mortality rate at home birth deliveries. A 2013 study showed that improved hand washing practices may lead to small improvements in the length growth in children under five years of age. In developing countries, childhood mortality rates related to respiratory and diarrheal diseases can be reduced by introducing simple behavioral changes, such as hand washing with soap. This simple action can reduce the rate of mortality from these diseases by almost 50%. Interventions that promote hand washing can reduce diarrhoea episodes by about a third, and this is comparable to providing clean water in low income areas. 48% of reductions in diarrhoea episodes can be associated with hand washing with soap.
How to encourage hand washing?

A hand sanitizer or hand antiseptic is a non-water-based hand hygiene agent. In the late 1990s and early part of the 21st century, alcohol rub non-water-based hand hygiene agents (also known as alcohol-based hand rubs, antiseptic hand rubs, or hand sanitizers) began to gain popularity.
How much less soap is used in hand washing?
Among the different inventions, there are eco-friendly devices that use 90% less water and 60% less soap compared to hand washing under a faucet. Another device uses light-based rays to detect contaminants on the hands after they have been washed.
Why is hand washing important?
The purpose of hand-washing in the health-care setting is to remove pathogenic microorganisms ("germs") and avoid transmitting them. The New England Journal of Medicine reports that a lack of hand-washing remains at unacceptable levels in most medical environments, with large numbers of doctors and nurses routinely forgetting to wash their hands before touching patients, thus transmitting microorganisms. One study showed that proper hand-washing and other simple procedures can decrease the rate of catheter-related bloodstream infections by 66 percent.
What is hand washing?
Hand washing is usually integrated with other sanitation interventions as part of water, sanitation, and hygiene ( WASH) programmes. Hand washing also protects against impetigo which is transmitted through direct physical contact.
