Asthma Asthma is a chronic (long-term) lung disease that inflames and narrows the airways. Asthma causes recurring periods of wheezing (a whistling sound when you breathe), chest tightness, shortness of breath, and coughing.

Bronchitis Bronchitis is an acute inflammation of the air passages within the lungs.

COPD (Chronic Obstructive Pulmonary Disease) COPD, or chronic obstructive pulmonary disease, is a progressive lung disease that gets worse over time, making it hard to breathe.

Coronavirus COVID-19 is a viral respiratory illness first in Hubei Province, China, in December 2019. The module offers a general introduction to the new coronavirus (COVID-19) and describes the infection and its close relationship to other coronaviruses, how it is spread, its incubation period and symptoms, treatment and most important — its prevention.


Flu (Influenza) Influenza, or "flu," is a contagious respiratory infection caused by several flu viruses. It may look like the common cold because it infects the same organs (nose, throat, lungs) and has similar symptoms. Influenza can cause mild to severe illness, and at times it can lead to death.

Lung Cancer This module for Health Care Professionals reviews lung functions. It then examines signs and symptoms and the diagnosis of lung cancer using a variety of methods. The module looks at staging and treatments of lung cancer including surgery, radiation and chemotherapy.

MERS (coronavirus) Middle East Respiratory Syndrome (MERS) is a viral respiratory illness first reported in Saudi Arabia in 2012. It is caused by a coronavirus called “Middle East Respiratory Syndrome Coronavirus” (MERS-CoV).

Pneumonia Pneumonia is an infection in one or both of the lungs. Certain types of bacteria, viruses, fungi, or parasites can cause pneumonia. Pneumonia is of a particular concern at the age of 65 or older, and if a patient has a chronic illness or impaired immune system.

Quitting Smoking Quitting smoking is the most important step that smokers can take to improve the length and quality of their lives, but it is not easy. Nicotine is the primary reason that quitting smoking is difficult. Nicotine, a drug found naturally in tobacco, is as addictive as heroin or cocaine.


Tuberculosis Tuberculosis ("TB" which is short for tubercles bacillus) is a disease caused by germs called Mycobacterium tuberculosis that are spread from person to person through the air. TB usually affects the lungs, but it also can affect other parts of the body such as the brain, the kidneys or the spine.

Upper Respiratory Tract Infection The upper respiratory tract consists of the nose, nasal cavity, larynx, trachea, and some of the sinuses and air cells. Upper respiratory tract infections include the common cold, influenza, laryngitis, pharyngitis, sinusitis, tonsillitis, and croup (in children).
