Yes. Inflammation of the bronchial tubes caused by either viruses or bacteria is contagious.
Possibly... Acute bronchitis can be contagious since the bacteria or virus causing it can be aerosolized w/ cough or sneeze. If the infected person touches their nose and shakes your hand shortly after, it can be passed that way. Chronic bronchitis, a form of copd, is caused by airway inflammation usually due to smoking and is not contagious.
Bronchitis. Bronchitis is defined as an inflammation of the bronchial tubes of the respiratory infection. Cough is the predominant symptom. Usually this is self-limiting and will heal completely on its own. Most infections are viral although bacterial infections can cause bronchitis as well. Contrary to popular belief antibiotics are not always necessary. It is just as contagious as any viral infection.
Depends... Acute bronchitis is contagious via airway droplets from coughing and sneezing whereas chronic bronchitis, a form of copd, is not contagious but is usually the result of smoking.
Can be. If it is an infectious bronchitis depending on what the infectious etiology is the bug can be passed on to others through coughing. It can also be passed on through contact which highlights the importance of frequent hand washing. A mask is recommended if concern is present.
Not directly. Bronchitis, though frequently treated with antibiotics, is almost always caused by a viral infection. The virus is usually transmissible just like a cold, but the people who catch it, though they may get sick, won't necessarily get bronchitis.
Can be... Acute bronchitis is caused by either bacteria or viruses and these organisms can be aerosolized w/coughing/sneezing or spread via hand contact (ex. Infected person touches their nose and you shake their hand shortly afterwards!) chronic bronchitis is not contagious as it is a form of COPD and results from airway inflammation due to smoking (usually).
Depends. Person continues to be contagious as long as symptoms continue to be present.
Yes. Acute bronchitis is currently considered to be caused mostly by viruses, which are quite contagious. It can be transmitted in the air, by coughing, and by contact with the sick person's hands (if the hands have been coughed on or touched the mouth). The most contagious period is usually early in the illness, and shortly before the illness begins to show symptoms.
No... Chronic bronchitis is a form of copd. It is usually a result of smoking. There is no infection present in chronic bronchitis. Smoking cessation is important for prevention.
Mostly YES. Pneumonia or acute bronchitis are respiratory illnesses caused by viruses or bacteria. Typically these are spread by droplets when an infected individual coughs. It is flu season! Limit the spread by staying home from work when you are sick and covering your cough. But some conditions, like chronic bronchitis, are lung problems that can flare or get worse without infection and aren't contagious.
Yes. Both, usually they come from viruses ; bacterias that came from inhalation from a person who coughed before or close by.
Depends.... There are many different bacteria and viruses that can cause acute bronchitis, each with a different incubation period and shedding time. So, the amount of time a person is contagious depends on which organism is causing the infection.
It is not contagious. Acute bronchitis is a reaction to a viral respiratory infection (vri) by suseptible indiviuals, leading to frequent cough, increased mucus production, chest tightness, wheezing. Less than 20% of the population over react to the irritation of a vri with symptoms noted previously. The underlying vri is contagious for 24 hr before the onset of symptoms and for about 5 days after the symptoms begin.
Days to weeks. Depends on the causative organism, or if the pt has been a chronic smoker then it may be a inherent tendency to have generally inflamed airways without any infection and hence not being contagious.
