Final answer:
Rotaviruses and Hepatitis A are significant waterborne illnesses, with rotaviruses causing severe diarrheal diseases, particularly in children. Hepatitis B is not typically waterborne. Proper sanitation and vaccinations are essential in combating these diseases.
Step-by-step explanation:
Waterborne diseases pose significant health risks and are caused by pathogens that can be transmitted through contaminated water. Among the illnesses listed, rotaviruses are noted for causing severe diarrheal disease, especially in children, and can be a leading cause of death in this age group in the developing world.
Hepatitis A also represents a serious health issue transmitted through water, causing inflammation of the liver. Both of these are viral infections that are major concerns in areas lacking proper water treatment facilities.
Fortunately, sanitation and vaccinations can diminish these threats. Gut issues, although general, can be a symptom of several waterborne diseases.
As a summary, both rotaviruses and Hepatitis A pose significant health risks when transmitted through water. Hepatitis B, while a serious illness, is primarily spread through blood and bodily fluids, not water. Diarrheal diseases are often linked to unsafe water supplies and can be fatal, especially in children in the developing world.
