#1 Hepatitis A

The Hepatitis A virus (HAV) is a long lasting-lasting disease that can affect your health for months. This disease is known worldwide as a liver disease that comes with symptoms such as fatigue, low appetite, stomach cramps, nausea, and jaundice.

Hepatitis A is usually spread by drinking contaminated water or consuming contaminated food, but it can also be spread through faecal-oral route person-to-person.  

The good news is that if you want to protect yourself from the disease and prevent getting infected, you have the option to get vaccinated. 

#2 E. coli

E. coli, also known as Escherichia coli, can usually be found in food, water, and the intestines of animals and people. However, in most cases, the E.coli bacteria is harmless for human health, it doesn’t mean that you shouldn’t be aware of the possible problems it can cause. 

When getting infected with E.coli bacteria, some people develop unpleasant symptoms and get seriously sick. Just to mention some, the most common symptoms of E. coli infection are severe diarrhoea, urinary tract infections, respiratory illnesses, pneumonia or other illnesses.

#3 Legionella

Another dangerous bacteria is Legionella which is known as the main cause of Legionnaires’ disease. This disease is a serious type of lung infection, that can seriously damage the lungs. Also, Legionella can lead to Pontiac fever, which is a milder, yet not less dangerous disease. 

The main way Legionella is transmitted is by breathing in contaminated mist or drinking contaminated water. It is also important to mention, that the bacteria is not equally dangerous to every age range. While young and healthy people usually won’t get sick from Legionella, elders, smokers and people with weakened immune systems or chronic diseases are part of the high-risk category. This means that these people can develop serious symptoms and for them getting infected might even lead to their deaths. 

#4 Norovirus

Norovirus is a highly contagious microorganism that can be spread easily in multiple ways. Being a quickly spreading contaminant, you can easily get with Norovirus by having direct contact with someone that is infected. Another way to contact Norovirus is through consuming contaminated water or food. Touching contaminated surfaces, then putting your unwashed hands into your mouth is also a common way to get infected.

The two most common symptoms of Norovirus are vomiting and diarrhoea.

#5 Shigella

Shigellosis which is a very infectious disease is caused by the highly occurring bacteria named Shigella. This disease is a long-lasting sickness with severe symptoms such as diarrhoea, fever and stomach pain.   

This disease has a long-term effect after exposure, it usually takes 5 to 7 days until it resolves. Similarly to Legionella, this bacteria can affect more people with weakened immune systems that usually face increased risk and a long sickness period.

Depending on the type and level of contamination or infection, we can talk about the short-term effect and long-term effect after exposure:


  • Short-term or immediate effect after exposure: Some water contaminants, such as viruses and bacteria can have an impact on your health immediately or shortly after you consume the contaminated water. 
  • Long-term effect after exposure: Other health-related water contaminants, such as fluoride or chlorine has a long-term effect on your health after exposure.
