Which type of diseases can be attributed to improper management of OSSF?

In the context of improper management of On-Site Sewage Facilities (OSSF), infectious diseases are correctly identified as a primary concern. When sewage is not adequately treated or contained, pathogens such as bacteria, viruses, and parasites can contaminate water sources or the surrounding environment. This contamination poses a direct risk to human health, as individuals could be exposed to these pathogens through water supply, recreational water, or even through contact with contaminated soil.

When improper sanitation leads to the spread of infectious agents, it can result in illnesses ranging from gastrointestinal infections to more severe conditions. The relationship between water quality and public health demonstrates how critical proper OSSF management is to prevent disease transmission.

Other types of diseases mentioned in the options can have diverse causes and may not be directly linked to the management of OSSF. For instance, respiratory diseases may arise from air quality issues that are not necessarily tied to sewage management, neurological diseases can have various genetic or environmental triggers, and cardiovascular diseases are often related to lifestyle factors rather than sanitation practices. Therefore, infectious diseases are correctly identified as the primary health risk associated with inadequate OSSF management.
