Topic:
Diseases transmitted by polluted water/ waterborne diseases
Introduction:
In this presentation, we will introduce to you the ways of mass water pollution. We will also present the most common diseases transmitted by dirty water/waterborne diseases as well as their prevention. To begin with, we will learn more about dirty/polluted waters in Bulgaria as well as waste management and its impact.
The generation of household/solid waste in Bulgaria slightly increased in 2020 but remains below the EU average. Contrary to the desired trend, there is an increase in the use of landfills and a decrease in recycling.
Recycling of household waste (including composting) increased to 35% in 2017 but is still low compared to the EU average of 46%. Bulgaria still has one of the highest landfill rates at 62% (2017) compared to the EU average of 24%. The country must either close or rehabilitate numerous non-compliant landfills.
All over the world, diseases caused by water pollution lead to widespread illness or even death. While not every disease caused by water pollution is fatal, a large number are. Unfortunately, many of the countries facing these diseases are underdeveloped and poor, meaning that the population lacks access to quality health care and treatment options. However, these types of diseases affect people on a global scale, and geography has little to do with it.Let’s begin...
Now we are going to see a short video about contamination and waterborne diseases...
By watching this video we learned the definition of contamination and its causes; ways to prevent it and most importantly the consequences of it. The main reason for it, presented in the video, is the improper disposal of sewage which leads to the leakage of material into the soil. We see that even draining industrial and agricultural water into water bodies may lead to water contamination because of the poisonous chemicals they contain such as mercury. Consequently, consuming polluted water can lead to abnormalities in the nervous system, hormonal imbalances, cancer, and many fatal diseases.
Diseases caused by polluted water/ waterborne diseases
We divide these diseases into three types: bacterial, viral, and parasitic. We will present two diseases of each type:
parasitic
viral
bacterial
Bacterial diseases:
Salmonella:
Escherichia coli
The most common symptoms of salmonella are fever, diarrhea, and stomach pain. It usually goes away in about a week. In some cases, dehydration may occur, and in others, the bacteria may spread throughout the body and even infect the patient's blood.
The most common symptoms of an E. coli infection are watery or bloody diarrhea, stomach pains and cramps, nausea, and vomiting. Bloody diarrhea is a sign that you should seek medical attention.
Viral diseases:
Fever
Hepatitis A
Symptoms include fever and fatigue, diarrhea, vomiting, loss of appetite, and jaundice. In severe cases, liver failure may occur. The virus is spread through contaminated water.
Fever or high fever is one of the most well-known signs of this disease. Muscle pain, headache, swollen joints, rashes, and vomiting usually occur at this temperature.
Parasitic diseases:
Hookworm:
Meningitis
Symptoms include a stiff neck, severe headache, nausea and vomiting. While parasitic meningitis is rare compared to other types of meningitis, it can be caused by one of three types of parasites: angiostrongylus cantonensis and baylisacaris procyonis.
Stomach pain and cramps, fever, loss of appetite, rash, and bloody stools are signs of hookworm infection. This disease is a parasite that spreads through feces. However, it can survive in water and usually uses water to find its way to a new host
Prevention and recommended precautions to be healthy and consume clean water:
Always cook meat and eggs thoroughly before consuming them.
Wash your hands after contact with reptiles or animals.
Avoid washing yourself or your clothes in untreated water.
Disinfect all kitchen surfaces after preparing raw meat
Always vaccinate your pets for parasites
How much is our water supply available at the moment?
1.8 billion people worldwide use contaminated drinking sources, which is associated with epidemic outbreaks of infectious diseases.
842,000 people die annually from the use of contaminated water and poor sanitation.
According to the WHO, access to safe water generates an economic gain of $84.4 billion annually. Profit on a global scale is also realized by the efforts of each of us to change our attitude towards water resources and their storage.
Of all the water on Earth, currently, only 0.5% is suitable for drinking.
Through this project we wanted to send a message to you. Water is life and without it our existence and survival are impossible.Let's keep the waters clean!
