Respiratory tract infections are infections of the nose, sinuses, throat, airways or lungs. Upper infections include colds, sinusitis and tonsillitis, and lower infections include bronchitis and pneumonia. Most are caused by viruses and clear up on their own within 1 to 2 weeks without antibiotics. Antibiotics are used only when a doctor finds or suspects a bacterial infection, such as bacterial pneumonia.

Common questions

Do I need an antibiotic for a chest or throat infection?

Usually not. Most respiratory infections, including colds, flu and most coughs and sore throats, are caused by viruses and get better on their own. Antibiotics do not help viral infections. A doctor may prescribe one if a bacterial infection such as pneumonia is likely; if so, take the full course.

When should I see a doctor for a respiratory infection?

See a doctor if you feel very unwell or are getting worse, have a high temperature for more than 3 days, cough up blood, or have a cough lasting more than 3 weeks. Also see one early if you are pregnant, over 65, have a weak immune system or a long-term heart, lung or kidney condition.
