Preventing the spread of diseases means breaking the chain of infection transmission so that infection cannot spread. "Targeted hygiene" is based on identifying the routes of pathogen spread in the home and introducing hygiene practices at critical times to break the chain of infection.{{cite book|title=Developing and promoting hygiene in home and everyday life to meet 21st Century needs|publisher=the International Scientific Forum on Home Hygiene|date=July 2021|url=https://www.ifh-homehygiene.org/sites/default/files/publications/2021%20IFH%20White%20Paper%2038pp%20%281%29.pdf|url-status=dead|archive-url=https://web.archive.org/web/20220517010101/https://www.ifh-homehygiene.org/sites/default/files/publications/2021%20IFH%20White%20Paper%2038pp%20%281%29.pdf |archive-date=2022-05-17 }} It uses a [[probabilistic risk analysis|risk-based approach]] based on Hazard Analysis Critical Control Point ([[HACCP]]).{{cn|date=April 2023}} [29] => [30] => The main sources of infection in the home are people (who are carriers or are infected), foods (particularly raw foods), water, pets, and domestic animals. Sites that accumulate stagnant water – such as sinks, [[toilet]]s, waste pipes, cleaning tools, and face cloths – readily support microbial growth and can become secondary reservoirs of infection, though species are mostly those that threaten "at risk" groups. [[Pathogens]] (such as potentially infectious bacteria and viruses – colloquially called "germs") are constantly shed via mucous membranes, feces, vomit, skin scales, and other means. When circumstances combine, people are exposed, either directly or via food or water, and can develop an infection.{{cn|date=April 2023}} [31] => [32] => The main "highways" for the spread of pathogens in the home are the hands, hand and food contact surfaces, and cleaning cloths and utensils (e.g. [[fecal–oral route]] of transmission). Pathogens can also be spread via clothing and household linens, such as [[towels]]. Utilities such as toilets and wash basins were invented to deal safely with human waste but still have risks associated with them. Safe disposal of human waste is a fundamental need; poor [[sanitation]] is a primary cause of diarrhea disease in low-income communities. Respiratory viruses and fungal spores spread via the air.{{cn|date=April 2023}} [33] => [34] => Good home hygiene means engaging in hygiene practices at critical points to break the chain of infection. Because the "infectious dose" for some pathogens can be very small (10–100 viable units or even less for some viruses), and infection can result from direct transfer of pathogens from surfaces via hands or food to the mouth, nasal mucous, or the eye, "hygienic cleaning" procedures should be adopted to eliminate pathogens from critical surfaces.{{cn|date=April 2023}} [35] => [36] => ===Hand washing=== [37] => [[File:Hand Hygiene Sign in Public Restroom.jpg|thumb|Hand hygiene sign in public restroom]] [38] => {{excerpt|Hand washing|paragraphs=1,2|file=no}} [39] => [[File:Finished UDDT in Pumpuentsa (5630907486).jpg|thumb|A tippy tap for handwashing after using a [[urine-diverting dry toilet]] in Pumpuentsa, Ecuador]] [40] => [41] => ===Respiratory hygiene=== [42] => Correct respiratory and [[hand hygiene]] when coughing and sneezing reduces the spread of pathogens particularly during the [[cold]] and [[flu]] season: [43] => * Carry tissues and use them to catch coughs and sneezes, or sneeze into your elbow.

The lack of quantitative data linking contaminated clothing to infection in the domestic setting makes it difficult to assess the extent of this risk.{{cite journal |vauthors=Larson EL, Lin SX, Gomez-Pichardo C |title=Predictors of infectious disease symptoms in inner city households |journal=Nurs Res |volume=53 |issue=3 |pages=190–97 |year=2004 |pmid=15167507 |doi= 10.1097/00006199-200405000-00006|s2cid=46126212 }} This also indicates that risks from clothing and household linens are somewhat less than those associated with hands, hand contact and food contact surfaces, and cleaning cloths, but even so these risks need to be managed through effective laundering practices. In the home, this should be carried out as part of a multibarrier approach to hygiene which includes hand, food, respiratory, and other hygiene practices. [61] => [62] => Infectious disease risks from contaminated clothing can increase significantly under certain conditions - for example, in healthcare situations in hospitals, care homes, and the domestic setting where someone has diarrhoea, vomiting, or a skin or wound infection.

The risks are not apparent until, for example, they are admitted to hospital, when they can become "self infected" with their own resistant organisms following a surgical procedure. As persistent nasal, skin, or bowel carriage in the healthy population spreads "silently" across the world, the risks from resistant strains in both hospitals and the community increases. In particular the data indicates that clothing and household linens are a risk factor for spread of [[Staphylococcus aureus|''S. aureus'']] (including MRSA and [[Panton–Valentine leukocidin|PVL]]-producing MRSA strains), and that effectiveness of laundry processes may be an important factor in defining the rate of community spread of these strains.{{cite web |vauthors=Bloomfield SF, Cookson BD, Falkiner FR, Griffith C, Cleary V |year=2006 |title=Methicillin resistant ''Staphylococcus aureus'' (MRSA), Clostridium difficile and ESBL-producing Escherichia coli in the home and community: assessing the problem, controlling the spread |publisher=International Scientific Forum on Home Hygiene |url=https://ifh-homehygiene.org/review-best-practice/methicillin-resistant-staphylococcus-aureus-mrsa-clostridium-difficile-and-esbl/}} Experience in the United States suggests that these strains are transmissible within families and in community settings such as prisons, schools, and sport teams. Skin-to-skin contact (including unabraded skin) and indirect contact with contaminated objects such as towels, sheets, and sports equipment seem to represent the mode of transmission. [65] => [66] => During laundering, temperature and [[Laundry detergent|detergent]] work to reduce microbial contamination levels on fabrics. Soil and microbes from fabrics are severed and suspended in the wash water. These are then "washed away" during the rinse and spin cycles. In addition to physical removal, micro-organisms can be killed by thermal inactivation which increases as the temperature is increased. Chemical inactivation of microbes by the surfactants and activated oxygen-based bleach used in detergents contributes to the hygiene effectiveness of laundering. Adding hypochlorite bleach in the washing process achieves inactivation of microbes. A number of other factors can contribute including drying and ironing.

More about us

About

It encompasses a wide range of behaviors and routines that are aimed at preventing the spread of diseases and maintaining personal wellbeing. This includes practices such as regular handwashing, taking showers or baths, brushing teeth, wearing clean clothes, and properly disposing of waste. The concept of hygiene has been recognized and valued for centuries, with ancient civilizations like the Egyptians and Greeks developing their own hygiene practices. However, the modern understanding of hygiene and its importance in maintaining public health emerged in the 19th century with the discovery of germs and their role in causing disease. Good hygiene practices have a significant impact on preventing the transmission of infectious diseases such as colds, flu, and gastrointestinal infections. Through proper hygiene, individuals can reduce the risk of contracting and spreading illnesses. Hygiene also plays a critical role in preventing healthcare-associated infections, especially in hospitals and other medical settings. Promoting good hygiene practices is essential in both personal and public settings. Public health campaigns often educate individuals on the importance of hand hygiene, using clean water and sanitation facilities, and maintaining hygienic practices in food preparation and storage. Additionally, hygiene is a crucial component of various sectors such as food safety, environmental health, and occupational health. Maintaining personal hygiene has numerous benefits beyond disease prevention. It enhances an individual's physical appearance, boosts self-confidence, and contributes to overall mental and emotional wellbeing. Teaching children and promoting proper hygiene habits from an early age is crucial in establishing lifelong routines that will promote a healthy and fulfilling life. While hygiene practices are highly effective in maintaining health, they are not accessible to everyone worldwide. Many individuals lack access to clean water, sanitation facilities, and basic hygiene supplies. Inadequate hygiene conditions can contribute to the spread of diseases, particularly in impoverished communities. Overall, hygiene is a fundamental aspect of human health that encompasses various practices and behaviors aimed at maintaining cleanliness and preventing the spread of diseases. It is essential for individuals, communities, and societies to prioritize and promote good hygiene practices to protect public health and ensure overall wellbeing.
