There are two ways to treat an infectious disease (transmission)
That is:
Reduce the effects of the disease: This can be done by providing symptomatic treatment. We can provide treatment that will reduce symptoms. For example, we can take the medication that runs out of fever, reduce pain or loose movement. We can also rest in bed to keep our energy. These steps will allow us to focus on healing. However, such symptom-oriented treatment is not enough as it will not eliminate the pathogenic bacteria from the body. In order to cure a disease, the virus must be killed.
To destroy the cause of a disease, i.e. a pathogen: The most common method to kill pathogenic bacteria is the use of a drug that kills the bacteria. Pathogenic bacteria are classified into different groups such as viruses, bacteria, fungi and protozoa. Each of these groups of microorganisms has essential biochemical life processes that are unique to that group and not shared with other groups. Our cells have different pathways than those used by these groups of bacteria. So we found a drug that blocks; for example, the biochemical pathway of bacteria without affecting us. That’s what antibiotics get. Likewise, there are drugs that kill protozoa, for example, the malaria parasite.
