Bronchitis in one year old babies can usually be cured in 7-10 days after treatment. Bronchitis is a lower respiratory tract infection, often caused by colds. Colds are often caused by viral infections, which can affect the lower respiratory tract when the child’s resistance is lowered after infection or when the amount of virus infected at one time is relatively large. Bronchitis can be characterized by fever or no fever, and is characterized by coughing and sputum, with varying frequency of coughing. If the bronchitis is caused by mycoplasma, the child may have a more pronounced cough at night and a predominantly dry cough. Treatment depends on the pathogen, generally viral infections caused by bronchitis, often combined with bacterial infections, so the use of penicillin or cephalosporin antibiotics, coupled with cough and phlegm medication, such as children’s cough and phlegm granules and aminoglutethimide drugs.
