Treatment and health care[edit] Bacteria are usually treated with antibiotics while viruses are treated with antiviral compounds. Eukaryotic pathogens are typically not susceptible to antibiotics and thus need specific drugs. Infection with many pathogens can be prevented by immunization.
One reason bacteria are becoming resistant is because antibiotics are often inappropriately used for an illness caused by a virus. Antibiotics cannot kill viral illnesses. Examples of illnesses that are caused by viruses include: 1  most sore throats (pharyngitis) 2  coughs, colds and runny noses (rhinitis) 3  sinus infections, respiratory tract infections (sinusitis, bronchitis) 4  the flu (influenza virus)
