Common Infectious Lung Diseases

Influenza

Influenza, more commonly called the flu, is a contagious respiratory disease caused by a virus. Most healthy people will recover from the flu on their own within one or two weeks. For the very young, the elderly and people with prior medical conditions, however, influenza can lead to serious of even fatal complications, most commonly pneumonia.

Influenza symptoms usually come on suddenly. Generally, a person will have a high fever for about 3 days. Respiratory symptoms, which include a sore throat, cough, runny or stuffy nose, usually last an additional three or four days. A person may also continue to have a dry, hacking cough for up to 10 days after other symptoms are gone. Headaches, fatigue, weakness, muscle aches and loss of appetite are other common symptoms of influenza.

Cold or Flu?

Although they are often mistaken for each other, there are some key differences between the common cold and the flu:

SYMPTOMS	COLD	FLU
Fever	Rare	Characteristic, high (102-104 degrees F)
Headache	Rare	Prominent
General aches and pains	Slight	Usual; often severe
Fatigue, weakness	Quite mild	Can last up to 2-3 weeks
Extreme exhaustion	Never	Early and prominent
Stuffy nose	Common	Sometimes
Sneezing	Usual	Sometimes
Sore throat	Common	Sometimes
Chest discomfort, cough	Mild to moderate; hacking cough	Common; can become severe

Prevention:
The best way to prevent the flu is to receive a flu vaccine every year. You can also prevent the spread of the flu by practicing good personally cleanliness. For example, wash your hands often, avoid touching your eyes, mouth and nose, and refrain from sharing drinks or utensils with others. Also, cover your mouth when you cough or sneeze to prevent spreading the disease to others if you are already infected.

Treatment:
For a common case of the flu, the best treatment is to rest and drink plenty of fluids. Antiviral drugs can treat particular strains of influenza. These are most effective when taken within two days of then symptoms appear. Antiviral drugs may help to reduce the duration of the disease, but they should not be used in place of a vaccination.

Tuberculosis

Tuberculosis is an infectious disease that most often affects the lungs, but can attack other parts of the body, as well.  TB bacteria can be transmitted from one person to another through the air.  Those most at risk for contracting the disease are people who share confined air space with an infected person. Contact the County Health Department or see your doctor for additional information.

Symptoms can include: A cough lasting more than two weeks, weight loss, fatigue, night sweats, and/or fever.

Pertussis (Whooping Cough)

Pertussis, widely known as “whooping cough” is a contagious bacterial infection of the respiratory system. It’s called “whooping cough” because when infected you gasp for air between bouts of uncontrollable coughing. Whooping cough is treated with antibiotic medications. Ask your doctor about a preventative vaccine.

Pneumonia

Pneumonia is an infection of the lungs that can be caused by various microorganisms, including viruses, bacteria, fungi and parasites. The viral and bacterial agents that cause pneumonia are contagious. Some types of viral and bacterial pneumonia can be prevented by a vaccination.

Symptoms can include: fever, chills, coughing, labored or rapid breathing, chest or abdominal pain.

Lung Disease Processes

Asthma

Asthma is a long term disease of the airways to allergens and irritants (triggers), which cause the air passages in the lungs to become inflamed and narrow or blocked by bronchospasm, and mucus production. The person must be aware of their triggers, warning signs and follow their medication regime. Treatment can reverse the inflammation and the muscle spasms. If left uncontrolled, there can be damage with airway remodeling.

Symptoms may be different for each person and may include: coughing, chest tightness, wheezing, shortness of breath, difficulty breathing.

Chronic Bronchitis

Chronic Bronchitis is diagnosed when you cough up mucus and experience shortness of breath for three months or more each year for at least two years. These symptoms occur when the lining of the bronchioles (airways) become inflamed and produces too much mucus. The airways narrow and the cilia (hair that lines the airways) are damaged, making them unable to remove the excess mucus.

Emphysema

Emphysema is a disease in which the walls of the alveoli (air sacs) do not function or fracture (break), making it difficult for the lungs to absorb enough oxygen or expel enough carbon dioxide. The walls of the alveoli lose their elasticity and become enlarged. As they enlarge, the diaphragm, (muscle below the lungs) flattens, making it harder for the lungs to move air in and out. The airways also become less elastic and narrow or collapse when exhaling; therefore carbon dioxide becomes trapped.

COPD (Chronic Obstructive Pulmonary Disease)

Chronic obstructive pulmonary disease (COPD) is a lung disease in which the lungs are damaged, making it hard to breathe. In COPD, the airways—the tubes that carry air in and out of your lungs—are partly obstructed, making it difficult to get air in and out and cells in the airways make more mucus (sputum) than usual, which clogs the airways. COPD refers to a group of diseases that will share one common feature difficulty exhaling air from the lungs.

In the United States, chronic obstructive pulmonary disease (COPD) includes: Emphysema & Chronic Bronchitis

Cigarette smoking is the most common cause of COPD. Most people with COPD have a combination of bronchitis and emphysema and are smokers or former smokers. Breathing in other kinds of lung irritants, like pollution, dust, or chemicals, over a long period of time may also cause or contribute to COPD. COPD develops slowly, and it may be many years before you notice symptoms like feeling short of breath. Most of the time, COPD is diagnosed in middle-aged or older people.

Other Lung Threats

Naturally Occurring Asbestos

Naturally Occurring Asbestos, also known as NOA, can be found in 44 of California’s 58 counties in rock formations called serpentine. Microscopic fibers are released from either natural erosion or other disturbance.  The State of California recognizes NOA as a known human carcinogen.  These small fibers can lodge deep in the lungs, and after a long latency period, can cause various lung diseases such as mesothelioma, asbestosis, and lung cancer. Risk levels are proportional with the amount of exposures and the length of time since the first exposure.
