What is needed to fight infection?

To effectively fight infection, the body relies on a robust immune system, which includes white blood cells, antibodies, and various biochemical processes. Adequate nutrition, hydration, and sleep are also essential for maintaining immune function. In some cases, medical interventions such as antibiotics or antivirals may be necessary to target specific pathogens. Additionally, vaccinations can help prevent infections by priming the immune system to recognize and combat harmful microbes.
