Antiviral drugs typically reduce the severity/duration of viral infections. Bacteria: are the most plentiful and pathogenic agents, but most don"t cause disease, cause harm by either releasing enzymes or toxins, antibiotics can kill bacteria, but not viruses. Fungi: yeasts, moulds, mushrooms, absorb nutrients from host, causes damage, release enzymes, causes damage, anti fungal drugs treat fungi.
