viral
which type of infection does acute bronchitis usually follow
it is a LRTI which follows a URTI
describe the cough in acute bronchitis
productive - CLEAR sputum

improves over time in acute bronchitis
dissent in asthma
Tx for acute bronchitis
if high CRP or pre existing conditions
- oral doxycycline
(or amoxicillin in pregnant women/children)
is influenza a URTI or LRTI
both
is tonsillitis a URTI or LRTI
URTI
which test can diagnose influenza
