What is the primary sign of good health relating to infections?

The primary sign of good health relating to infections is immunity. Immunity refers to the body's ability to resist and fight off infections through its immune system. A strong immune system can effectively identify and neutralize pathogens, helping to prevent diseases and infections from taking hold. This means that individuals with robust immunity are less likely to become ill or suffer from infectious diseases, which is a clear indicator of good health.

While inflammation is a natural response to pathogens and plays a role in the healing process, it is not a sign of good health itself, as persistent inflammation could indicate an underlying health issue. Infection, by nature, signifies that a harmful agent has invaded the body, and aging can affect immune response but is not a direct indicator of health regarding infections. Rather, strong immunity is a proactive defense that helps maintain overall health and well-being.
