China CDC surveillance shows rhinovirus is now the dominant respiratory
pathogen. Healthy adults usually recover in 7–10 days; infants, the elderly,
immunocompromised patients and those with asthma or COPD may develop
bronchiolitis or COPD exacerbations. Seek medical care for fever >3 days, severe
lethargy, dyspnea/chest tightness, or infant feeding refusal/dehydration. No
specific antiviral exists; treatment is supportive care. Antibiotics and
oseltamivir are ineffective against rhinovirus.
