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.
This misdirected treatment can then promote antibiotic-resistant properties in harmless bacteria that can be shared with other bacteria. Common viral infections that do not benefit from antibiotic treatment include: 1  Cold. 2  Flu (influenza). 3  Bronchitis. 4  Most coughs. 5  Most sore throats. 6  Some ear infections. 7  Some sinus infections.
