Common Questions About Chest Infection

Can I get a medical certificate for a chest infection?

Yes. Chest infections often need 1-2 weeks recovery. Our doctors can provide certificates for the time you need off work.

Do chest infections always need antibiotics?

No. Most bronchitis is viral and antibiotics won't help. If a bacterial infection is suspected, antibiotics may be recommended.

How long does a chest infection last?

Most chest infections improve within 7-10 days, but the cough can linger for 3-4 weeks. See a doctor if symptoms aren't improving after a week.

Is a chest infection contagious?

The infection itself is often viral and contagious. Stay home while you have a fever and cover coughs. Most people aren't contagious after a few days.
