How does the body “kill” COVID-19 if the person is asymptomatic and there are no medical interventions?

I was taught that symptoms of disease (i.e. the seasonal flu) were your body’s attempt to kill the disease. How do diseases “die off” in your body if there are no symptoms or medical interventions?

Your immune system is in all honesty quite powerful. It is also what causes the most damage if it overreacts. Having no symptoms does NOT mean that your body is not fighting the disease.

Think about what symptoms are. Cough is defined as the expelling of air from the lungs. This is done to clear them, preventing damage, such as fluid buildup in the case of a strong immune response. But in many cases, the immune system does not mount such a strong response, and pathogens are killed without the need for coughing.

Fever is a way of increasing body temperature to misfit the ideal temperature range of pathogens. But in many cases, that is not needed either.
