Discuss water related vector disease, differentiate between pathogenic and non pathogenic, write two pathogens present in untreated water and infection they cause?

Water-related vector diseases are illnesses caused by pathogens that are transmitted through water sources. These diseases can be spread through contaminated water, either through direct ingestion or through contact with the skin.

Pathogenic water-related vector diseases are caused by harmful microorganisms such as bacteria, viruses, and parasites. These pathogens can cause infections and illnesses in humans and animals. Examples of pathogenic water-related vector diseases include cholera, typhoid fever, and giardiasis.

Non-pathogenic water-related vector diseases, on the other hand, are caused by harmless microorganisms that do not cause infections or illnesses. These microorganisms may be present in water sources but do not pose a threat to human health. Examples of non-pathogenic water-related vector diseases include harmless bacteria and algae.

Two pathogens that are commonly found in untreated water sources and can cause infections are:

1. Escherichia coli (E. coli): E. coli is a type of bacteria that is commonly found in the intestines of humans and animals. However, certain strains of E. coli can cause infections when ingested through contaminated water. Symptoms of E. coli infection can include diarrhea, abdominal pain, and fever.

2. Cryptosporidium: Cryptosporidium is a parasite that can be found in untreated water sources, such as rivers and lakes. Ingesting water contaminated with Cryptosporidium can lead to an infection called cryptosporidiosis. Symptoms of cryptosporidiosis can include diarrhea, stomach cramps, and nausea.

It is important to ensure that water sources are properly treated and tested to prevent the spread of water-related vector diseases. Proper sanitation and hygiene practices can also help reduce the risk of infection from waterborne pathogens.
