Bronchitis is the swelling of the bronchial tubes, otherwise known as the airways. These airways are the windpipes that directly connect to the lungs.

Bronchitis happens when there is an irritation that occurs in the bronchial tubes. Next to the irritation, the formation of thick mucus will soon follow. Hence, the air passage will be blocked by the mucus, leading to difficulty in breathing.

Bronchitis can be identified into two types: acute and chronic.

The acute bronchitis is normally an illness that lasts for a short period of time. Usually, this is caused by severe cold. But most often, this is triggered by the viral infections.

Acute bronchitis is characterized by the pain in the middle of the chest, cough that comes with green sputum. Fever might also happen, and a slight difficulty in breathing might also occur.

The Chronic bronchitis on the other hand is identified with a cough that produces mucus. And this lasts for longer period of time as compared to the acute bronchitis.

The sufferers of bronchitis are also identified to suffer from different level of breathing difficulty. These sufferers may also have the possibility to attain lung infections sometimes. Hence, the breathing difficulty is worsen.

There are certain occasions where chronic bronchitis is termed as "chronic obstructive lung disease" and "chronic obstructive airways disease." From the terms themselves, the problem can already be identified—difficulty in air circulation that goes in and out of the lungs.

Now, the question comes, is bronchitis contagious?

The answer is yes. Bronchitis is extremely contagious. The virus can be transmitted by the means of cough, sneeze, and yes, even by simply touching the things that has been touched by the person infected.

Bronchitis, basically, is the swelling of the bronchia, thus, it is not contagious. However, as the bacteria starts to form, the disease then is contagious the moment the bacteria was emitted into the air.

In fact, there are already several affected people who confessed that they had the disease when they had a close contact with the infected person.

Now, the question is how long is bronchitis contagious?

According to the medical experts, the length of time of the disease contagiousness actually depends on the cause and type of the person's bronchitis.

For a person who suffers from bronchitis, it is suggested for him to visit and consult to a medical specialist of respiratory and pulmonary to assure whether he is already contagious and until when will it last.

It is advisable for the infected person to consult to a medical specialist when bronchitis tends to occur, if not, it may possibly lead to pneumonia.

Both the acute and chronic bronchitis have the threat to become contagious.

Even the healthy person is not safe from the attacks of acute bronchitis. This is because of the viral infection. These viral infections can be transmitted from one person to other through indirect and direct contact.
