Is Bronchitis Contagious and What are the Symptoms?

What is Bronchitis?

Bronchitis is the inflammation of the bronchi, the main air passages to the lungs. People who are suffering from bronchitis experience problems when breathing in air because their airways are blocked by huge amounts of mucus or phlegm.

Types of Bronchitis

Bronchitis is classified as acute or chronic depending on the duration of the illness and its cause.

– Chronic Bronchitis

This type of bronchitis develops as a result of continued inflammation and irritation of air passages over a considerable period of time. The leading causes of chronic bronchitis include prolonged exposure to polluted air and smoking. It can also result from other environmental factors such as dust, vapors, fumes, as well as pollen.

This type of bronchitis can lead to coughs and production of mucus that can last up to three months or longer. Sometimes it can be a sign of other health problems and can potentially lead to permanent lung damage. If you are suffering from this disease, it is very important to see a specialist.

– Acute Bronchitis

Acute bronchitis refers to an acute respiratory tract infection. Almost 90 % of all acute bronchitis cases result from a viral infection caused by influenza virus, respiratory syncytial virus, or rhinovirus, among others.

In addition, acute bronchitis can also be caused by bacteria. This type of bronchitis is easy to identify because it is accompanied by coughing and mucus production. It is not as serious as chronic bronchitis and it can get better with rest.

Is Bronchitis Contagious?

Bronchitis can be contagious or non-contagious depending on the type of bronchitis one is suffering from.

  • If you are suffering from acute bronchitis and happen to cough or sneeze, you will release millions of tiny droplets containing the viruses or bacteria that cause this disease. This means that you can easily spread it to an uninfected person through coughing or sneezing. Essentially, this means that acute bronchitis is highly contagious.
  • Conversely, chronic bronchitis is not caused by a virus. For this reason, it cannot be passed from one person to another. However, this is true for chronic bronchitis that is caused by irritation from environmental substances. It is also very important to understand that chronic bronchitis can turn into acute bronchitis as a result of a viral or bacterial infection.

How long is bronchitis contagious?

In most cases, this depends on the type of virus or bacterium that is responsible for causing your bronchitis. It is usual for a person to become contagious for at least three days to one week at most.

Your doctor will tell you to assume that you are still contagious so long as you have a cough or cold-like symptoms. At times, it is difficult to tell whether you are suffering from common cold or bronchitis because the symptoms are quite similar.

However, if you continue to cough for one week or more, and you don’t have any other cold symptoms, it is possible that you are suffering from bronchitis.

For how long can I remain contagious after getting treated?

In some cases, your doctor might find it necessary to prescribe some antibiotics to treat your bronchitis, especially if he/she suspects a secondary bacterial infection. After taking your antibiotics for about 7 days, your infection usually goes away. Once you notice that your symptoms are starting to disappear, and the mucus turns from green or yellow to white, you are likely not to be any more contagious.
