The overuse of antibiotics has ended in numerous sorts of micro-organism growing resistance to at least one or greater styles of antibiotics. This makes these micro-organisms plenty greater hard to deal with.

Antivirals

Examples include the viruses that cause:

·         HIV/AIDS

·         Herpes

·         Hepatitis B

·         Hepatitis C
