When body fails to expel infectious agents?

When the body fails to expel infectious agents, it can lead to persistent infections that may result in chronic inflammation, tissue damage, and a compromised immune response. This failure can occur due to various factors, including weakened immune systems, the ability of pathogens to evade immune detection, or the presence of biofilms. If left untreated, such infections can spread, leading to more severe health complications. Prompt medical intervention is often necessary to manage these situations effectively.
