What is the difference between waterborne and water related diseases?
2.2. The causes of water related disease include micro-organisms, parasites, toxins and chemical contamination of water. Other terms include ‘waterborne disease’, which implies direct spread and is used mainly to refer to disease caused by microbiological pathogens or chemical contaminants in water.
What are 3 types of waterborne pathogens?
The list of potential waterborne pathogens is extensive and includes bacteria, viruses, protozoa, and parasitic helminths.
What are examples of waterborne diseases?
Contagion by pathogenic microorganisms Some waterborne pathogenic microorganisms spread by water can cause severe, life-threatening diseases. Examples are typhoid fever, cholera and Hepatitis A or E. Other microorganisms induce less dangerous diseases.
What’s the difference between a virus and a bacteria?
1 Living or Not. Viruses are not living organisms, bacteria are. Viruses only grow and reproduce inside of the host cells they infect. 2 Size. Bacteria are giants when compared to viruses. 3 Mode of Infection. Their mode of infection is different.
Which is the smallest of all waterborne pathogens?
Viruses vary widely in size and shape and are the smallest of all waterborne pathogens as they typically range in size from 0.03 to 0.10 microns. Viruses are not living organisms, and are therefore unable to replicate without a host cell.
What kind of virus can you get from drinking water?
Also, viruses that are excreted through urine like polyomaviruses [5] and cytomegalovirus [6] can potentially be spread through water. Other viruses, such as influenza and coronaviruses, have been suggested as organisms that can be transmitted through drinking water, but evidence is inconclusive [5].
Why are there so many waterborne diseases in developing countries?
Waterborne virus-based diseases may be higher in developing regions, where there is widespread malnutrition and large populations of HIV-positive people. Regardless, there are few broad spectrum anti-viral drugs to treat these diseases. Certainly, there is good cause for controlling these waterborne viruses.
