What type of health risks are increased by inadequate sewage treatment?

Inadequate sewage treatment primarily increases health-related risks due to the potential spread of pathogens and contaminants that can affect human health. When sewage is not properly treated, it can lead to the contamination of water supplies, soil, and even food sources, exposing individuals to harmful bacteria, viruses, and parasites. This exposure can result in a range of health issues, including gastrointestinal diseases, respiratory problems, and other infectious diseases.

Additionally, the accumulation of untreated sewage can create breeding grounds for vectors like mosquitoes, which can further contribute to health issues by spreading diseases such as dengue fever and malaria. Thus, the correct identification of health-related risks highlights the critical importance of effective sewage treatment in safeguarding public health and preventing outbreaks of waterborne diseases.
