Which two viruses are commonly associated with sewage?

1. Rota and Corona

2. Hepatitis B and C

3. Rota and Hepa A

4. Flu and E.coli viruses

The correct answer is: Rota and Hepa A

The selection of Rota and Hepa A as viruses commonly associated with sewage is based on their transmission routes and sources. Rota, or rotavirus, primarily affects the gastrointestinal system and is known for causing severe diarrhea. It is often transmitted through the fecal-oral route, which can occur in environments contaminated with sewage. This makes it particularly relevant in discussions of sewage contamination scenarios. Hepatitis A, from the Hepa family, is another virus that spreads primarily through the fecal-oral route, notably in areas with poor sanitation or by consuming contaminated food or water, both of which can result from sewage exposure. The sewage can harbor both viruses due to their presence in human waste, leading to increased risk for individuals in contact with contaminated sources. In contrast, Hepatitis B and C are primarily transmitted through blood and bodily fluids rather than through contaminated water or sewage. Similarly, while E. coli is a bacterium associated with sewage, it does not fit the category of a virus. The flu, caused by the influenza virus, is mainly spread through respiratory droplets rather than through sewage, further distinguishing it from the correct choice. Thus, focusing on rotavirus and hepatitis A highlights the specific viruses that pose significant risks in sewage exposure contexts.
