researchers suspect that sewage leaked into the moose river. rates for which of the following diseases should be used to determine whether the human population using the river as a source of drinking water was exposed to sewage?
Rates for which diseases should be used to determine whether the human population using the river as a source of drinking water was exposed to sewage?
Answer:
When investigating whether the human population using the river as a source of drinking water was exposed to sewage due to a suspected leakage, researchers should consider looking at rates for diseases that are commonly associated with sewage contamination. Some diseases that can be indicators of exposure to sewage-contaminated water include:
-
Gastrointestinal Infections: Diseases like gastroenteritis, caused by pathogens like norovirus, Campylobacter, and Giardia, are commonly linked to sewage contamination. A spike in gastrointestinal infections in the population could indicate exposure to sewage.
-
Hepatitis A: Hepatitis A is a viral infection that can be transmitted through contaminated water sources, including sewage. Monitoring rates of Hepatitis A cases can provide insight into potential exposure to sewage.
-
E. coli Infections: Escherichia coli (E. coli) is a bacteria commonly found in human and animal feces. High levels of E. coli in water sources are a clear indicator of sewage contamination and can pose serious health risks to those using the water for drinking.
-
Cryptosporidiosis: Cryptosporidium is a parasite that causes the disease cryptosporidiosis, which leads to gastrointestinal problems. This parasite is resistant to chlorine disinfection and is often associated with sewage contamination.
By examining the rates of these diseases in the population using the Moose River as a source of drinking water, researchers can assess the likelihood of exposure to sewage and take appropriate measures to protect public health.
