<unk>  is inflammation of the bronchi (large and medium-sized airways) in the lungs that causes coughing. Symptoms include coughing up sputum, wheezing, shortness of breath, and chest pain.<unk>  can be acute or chronic. Acute<unk>  usually has a cough that lasts around three weeks, and is also known as a chest cold. In more than 90% of cases the cause is a viral infection. These viruses may be spread through the air when people cough or by direct contact. A small number of cases are caused by a bacterial infection such as Mycoplasma pneumoniae or Bordetella pertussis. Risk factors include exposure to tobacco smoke, dust, and other air pollution. Treatment of acute<unk>  typically involves rest, paracetamol (acetaminophen), and nonsteroidal anti-inflammatory drugs (NSAIDs) to help with the fever. Chronic<unk>  is defined as a productive cough – one that produces sputum – that lasts for three months or more per year for at least two years. Many people with chronic<unk>  also have chronic obstructive pulmonary disease (COPD). Tobacco smoking is the most common cause, with a number of other factors such as air pollution and genetics playing a smaller role. Treatments include quitting smoking, vaccinations, rehabilitation, and often inhaled bronchodilators and steroids. Some people may benefit from long-term oxygen therapy. Acute<unk>  is one of the more common diseases. About 5% of adults and 6% of children have at least one episode a year. Acute<unk>  is the most common type of<unk> . By contrast in the United States, in 2018, 9.3 million people were diagnosed with the less common chronic<unk> .
