Bronchitis is inflammation of the bronchi (large and medium-sized airways) in the lungs that causes coughing. Bronchitis usually begins as an infection in the nose, ears, throat, or sinuses. The infection then makes its way down to the bronchi. Symptoms include coughing up sputum, wheezing, shortness of breath, and chest pain.
An exception is when acute bronchitis is due to pertussis. [1] Tentative evidence supports honey and pelargonium to help with symptoms. [1] Acute bronchitis is one of the most common diseases. [3] [13] About 5% of adults are affected and about 6% of children have at least one episode a year. [7] [8] It occurs more often in the winter. [7]
The terms "intrinsic incubation period" and "extrinsic incubation period" are used in vector-borne diseases. The intrinsic incubation period is the time taken by an organism to complete its development in the definitive host. The extrinsic incubation period is the time taken by an organism to develop in the intermediate host. [citation needed]
Acute bronchitis can be defined as acute bacterial or viral infection of the larger airways in healthy patients with no history of recurrent disease. [8] It affects over 40 adults per 1000 each year and consists of transient inflammation of the major bronchi and trachea. [ 9 ]
[3] [38] It has an incubation period of 2 to 8 days. [3] Once infected, people are usually contagious for 3 to 8 days. In infants and in people with weakened immune systems, however, the virus may continue to spread for up to 4 weeks (even after they are no longer showing symptoms). [39]
Understanding this incubation period—the time between when a virus enters a person’s body and when they start feeling sick—is crucial for health officials. COVID-19 symptoms typically appear ...
The incubation period is 5–7 days (with a range of 3–10). [5] Symptoms can include a harsh, dry cough, retching, sneezing, snorting, gagging or vomiting in response to light pressing of the trachea or after excitement or exercise. The presence of a fever varies from case to case. [citation needed]
Typically one eye is affected after an incubation period of up to a week. [2] The eye becomes itchy, painful, burning and reddish and lymphadenopathy may be felt by the ear nearest the affected eye. [2] The symptoms may last around 10 days to three weeks. [2] It may be is associated with blurred vision, photophobia and swelling of the conjunctiva.
