If you get a cold the body can recover on its own, while other illnesses need medication. Why?
In: Biology
It depends on the cause and personal immune response of the infected person.
In general, viruses are very common so your body is more familiar with at least some variation of a cold causing virus and can adjust accordingly to help fight off the infections.
Bacteria, however, is less common and will sometimes (but not always) require the use of antibiotics to help your body fight off the disease.
Additionally, antibiotics *only* work on bacteria and have no effect on virus-infuced conditions, so they would only be prescribed for these cases.
So essentially, the viral conditions are the average joe shoplifters that your body deals with on the daily and doesn’t need any extra help handling.
The bacterial or rare viral conditions, however, are the less common gunmen that come in and would require a call for backup from the police.
