Mucus with yellowish-gray or green is one of the symptoms of bronchitis. Generally, the presence of mucus is not really alarming because the airways normally can produce mucus secretions every day but these secretions do not pile up because your throat can clear it and swallow it along with your saliva.

But when there is bronchitis, large amounts of mucus are produce and these have to come out when you are coughing.

If you have colored mucus that had lasted over three months, that must be a chronic bronchitis and you really have to see your doctor because any mucus that is not really white in color is said to be a sign of a secondary infection had developed.

But not all those who bronchitis can developed mucus as there are some who don't really developed it or there are some especially in the case of children who just swallow it.

Bronchitis is said to be acute if one or some of these symptoms of bronchitis have develop:

Sore throat
Chest congestion
Sinusitis
Wheezing sound
Slight fever
Soreness
Fatigue
Breathlessness
