How Sanitation Prevents Communicable Diseases and Infections
Personal hygiene is something that should be looked upon and taken care of in our day-to-day life. People sometimes immerse themselves in the loads of work that they forget to have time for their self-care, or people who live in poor living conditions don’t have access to clean water and healthy food. This, unfortunately, have diverse effects on people’s health, leading to the contamination of various disease. The prevention of certain illnesses or diseases related to poor hygiene is termed sanitation.
Poor hygiene comes in various forms, such as waste or unfiltered water, contaminated food, living near the gutter, dirty hands used for eating, and the kitchen not being sanitised well enough to cook food. It is said that over 1.7 billion people still don’t have access to toilets or washrooms. All these factors lead to certain illnesses or diseases that harm human health.
Hence, the World Health Organisation has taken various measures to prevent such conditions and encouraged people worldwide to follow them as much as possible. Following these measures can help many people be aware and not be victims of such ferocious diseases.
Lack of Sanitation
Sanitation is deemed as one of the most required preventive measures to tackle certain contaminated illnesses or diseases. Most people suffer from the said diseases due to a lack of proper sanitation. Most of the diseases caused due to inappropriate sanitation in human beings are related to intestinal and stomach diseases. Improper sanitation methods come in various forms. They are:
Usage of contaminated or unfiltered water for drinking and cooking foods.
Defecating and urinating in an open field like a forest, river, etc.
Living beside sewage or garbage disposal field.
Not cleaning the kitchen before and after meals.
Not washing hands before eating.
Usage of the same syringe, which was used many times.
Engaging with patients with contaminated diseases and not sanitising after.
Not following basic hygiene protocols in day-to-day life.
Disease Caused by Lack of Sanitation
Many contaminated diseases are caused due to lack of sanitation. Humans mostly suffer from intestinal parasitic diseases or stomach-related diseases due to improper sanitation. Some of the acute diseases are:
Helminth infections
Impaired cognitive functions (lack of mental awareness)
Pneumonia
Diarrhoea
Anaemia in children
Growth faltering in infants
Bloodborne diseases like Hepatitis B and C due to not sanitising syringes
These are some illnesses or diseases that are caused due to lack of proper hygiene methods. Most of the diseases are caused by intestinal parasitic worms. They directly affect the intestines of human beings. Henceforth, proper knowledge about basic hygiene methods is needed for everyone to be safe from these acute illnesses.
Importance of Sanitation
Basic hygiene and sanitation are the most needed measures required to this day. Most of the people around us are unaware of the fundamental knowledge of preventive measures of sanitation and its benefits. People need to look at the importance of proper hygiene to be safe from the said acute diseases. They can be harmful, as well as deadly for human beings. One must know all the measures of sanitation and should it as well. It's beneficiary for us and also for the people around us.
Effects of Poor Sanitation on People’s Life
People have irreversible effects on their lives because of these severe diseases. Sometimes it's too late for the people with limited resources, as they cannot tackle the upcoming calamity that falls upon them. Whereas is difficult for people who come from the lower class because they cannot afford medical help. That’s why it's necessary for everyone to have an awareness of the said diseases and their prevention.
Interesting Facts
In the 16th and 19th centuries, the modern age of sanitation was started in Europe when pail closets, outhouses, and cesspits were used to clean up human wastes.
Over 4.2 billion people used a safely managed sanitation service in 2020.
At least 10% of the world's population is thought to consume food irrigated by water.
Most people are still littering in open field areas due to the non-availability of proper and cleaned toilets.
Key Features
Sanitation is taking care of oneself to be safe from acute diseases.
Many of the world's population is still suffering from contamination diseases due to improper sanitation.
Most contaminated diseases or illnesses start from the intestines of human beings.
One should be aware of basic hygiene methods to prevent certain diseases.
All should follow preventive measures initiated by the World health organisation to prevent contaminated diseases.
Having a good sanitary habit is key to a healthy life. One should have basic hygiene habits in day-to-day life right from early life.
FAQs on Sanitation and Disease in Human Health
1. What is sanitation and why is it important for preventing disease?
Sanitation is the practice of maintaining clean conditions through proper disposal of waste and safe management of water to prevent disease transmission. It is important because poor sanitation allows pathogens such as bacteria, viruses, and parasites to spread easily.
Key roles of sanitation in disease prevention include:
- Preventing contamination of drinking water with human waste
- Reducing the spread of waterborne diseases like cholera and typhoid
- Controlling breeding sites of disease vectors such as mosquitoes and flies
- Improving overall public and environmental health
2. How does poor sanitation cause disease?
Poor sanitation causes disease by allowing harmful microorganisms to contaminate water, food, and living environments. When human waste is not properly treated or disposed of, pathogens spread through multiple routes.
Main mechanisms include:
- Contamination of water sources with fecal matter
- Transmission through the fecal–oral route
- Food contamination by flies and unclean hands
- Increased exposure to parasites in soil
3. What are waterborne diseases caused by poor sanitation?
Waterborne diseases are infections transmitted through contaminated water containing pathogens from human or animal waste. These diseases are common in areas with inadequate sanitation and unsafe drinking water.
Examples include:
- Cholera caused by Vibrio cholerae
- Typhoid fever caused by Salmonella typhi
- Dysentery caused by Shigella or Entamoeba histolytica
- Hepatitis A virus infection
4. What is the fecal–oral route of disease transmission?
The fecal–oral route is a mode of transmission in which pathogens from feces enter another person’s mouth through contaminated food, water, or hands. It is a major pathway for the spread of sanitation-related diseases.
The process typically involves:
- Infected person excretes pathogens in feces
- Feces contaminate water, soil, or food
- Another person ingests the contaminated material
5. What is the difference between sanitation and hygiene?
Sanitation refers to public systems for safe waste disposal and clean water supply, while hygiene refers to personal practices that maintain cleanliness and health. Both are essential for disease prevention but operate at different levels.
Key differences:
- Sanitation: Infrastructure like toilets, sewage systems, and waste management
- Hygiene: Individual behaviors like handwashing and bathing
- Sanitation reduces environmental contamination
- Hygiene reduces direct person-to-person transmission
6. How does proper waste disposal prevent infectious diseases?
Proper waste disposal prevents infectious diseases by eliminating breeding grounds for pathogens and disease vectors. Safe management of human and solid waste reduces environmental contamination.
It helps by:
- Preventing leakage of sewage into groundwater
- Reducing fly and rodent populations that spread infections
- Stopping the spread of intestinal parasites
- Maintaining clean surroundings that limit microbial growth
7. Why is handwashing important in sanitation and disease control?
Handwashing is important because it removes pathogens from the hands and prevents their transfer to the mouth, food, or other people. It is one of the simplest and most effective hygiene practices.
Critical times for handwashing include:
- After using the toilet
- Before preparing or eating food
- After handling waste
- After caring for a sick person
8. What are the common parasites associated with poor sanitation?
Common parasites associated with poor sanitation include intestinal worms and protozoa transmitted through contaminated soil or water. These organisms infect humans when sanitation systems are inadequate.
Examples include:
- Ascaris lumbricoides (roundworm)
- Ancylostoma duodenale (hookworm)
- Trichuris trichiura (whipworm)
- Entamoeba histolytica (amoebic dysentery)
9. How does sanitation help control vector-borne diseases?
Sanitation helps control vector-borne diseases by removing conditions that allow disease-carrying organisms to breed and multiply. Poor waste management and stagnant water promote vector growth.
Sanitation measures include:
- Eliminating stagnant water to control mosquitoes
- Proper garbage disposal to reduce fly populations
- Covering sewage systems to limit rodent access
10. What are the basic components of a good sanitation system?
A good sanitation system includes safe waste disposal, clean water supply, and effective sewage treatment to prevent disease spread. These components work together to protect public health.
Main components are:
- Access to safe and hygienic toilets
- Proper sewage treatment and disposal
- Reliable supply of safe drinking water
- Solid waste collection and management
