Bronchitis Respiratory Infection: Diseases of the Lung
Bronchitis is the inflammation of the bronchi, the main air passages to the lungs, it typically follows a viral respiratory infection. To be diagnosed with chronic bronchitis, you must have a cough with mucus most days of the month for at least 3 months. The symptoms of either kind of bronchitis include: Cough that produces mucus; if yellow green in color, you might be more likely to have a bacterial illness Shortness of breath worsened by exertion or mild activity Even after acute bronchitis has cleared, you may have a dry, nagging cough that lingers for several weeks.
Bronchitis is a Typical Infection Causing Inflammation and Irritation
If you suffer from chronic bronchitis, you might be prone to developing more severe lung ailments in addition to heart problems and infections, so you should be monitored by a doctor. Acute bronchitis is generally due to lung diseases, 90% of which are viral in origin. Continued attacks of acute bronchitis, which irritate and weaken bronchial airways over time, can result in chronic bronchitis.
Viral pathogens are the most common cause of respiratory infection in travelers; causative agents include adenovirus, respiratory syncytial virus, influenza virus, parainfluenza virus, human metapneumovirus, measles, mumps, rhinovirus, and coronavirus. Clinicians also have to consider new viral causes of respiratory infection in travelers, including Middle East Respiratory Syndrome (MERS) Coronavirus, avian influenza H5N1 (referred to as H5N1), and avian influenza H7N9 (referred to as H7N9). Certain voyagers have an increased danger of respiratory tract infection, including children, the elderly, and people with comorbid pulmonary afflictions, for example asthma and chronic obstructive pulmonary disease (COPD). Special situations that may necessitate clinical intervention include the following: Vaccines are available to prevent a number of respiratory diseases, including influenza, S. pneumoniae infection, H. influenzae type B infection (in young children), pertussis, diphtheria, varicella, and measles.
Only a small part of acute bronchitis diseases are caused by nonviral agents, with the most common organism being Mycoplasma pneumoniae. Study findings indicate that Chlamydia pneumoniae may be another nonviral cause of acute bronchitis. The obstructive symptoms of acute bronchitis, as established by spirometric studies, are very similar to those of mild asthma. In one study. Forced expiratory volume in one second (FEV), mean forced expiratory flow during the middle of forced vital capacity (FEF) and peak flow values decreased to less than 80 percent of the predicted values in nearly 60 percent of patients during episodes of acute bronchitis.
Recent Epidemiologic Findings of Serologic Evidence of C
Pneumoniae infection in adults with new-onset asthma suggest that untreated chlamydial infections may have a function in the transition from the intense inflammation of bronchitis to the chronic inflammatory changes of asthma. Patients with acute bronchitis have a viral respiratory infection with ephemeral inflammatory changes that produce sputum and symptoms of airway obstruction. Signs of reversible airway obstruction when not infected Symptoms worse during the work week but often improve during weekends, holidays and vacations Chronic cough with sputum production on a daily basis for a minimum of three months Upper airway inflammation and no evidence of bronchial wheezing Evidence of infiltrate on the chest radiograph Evidence of increased interstitial or alveolar fluid on the chest radiograph Usually related to a precipitating event, such as smoke inhalation Signs of reversible airway obstruction even when not infected Symptoms worse during the work week but tend to improve during weekends, holidays and vacations Chronic cough with sputum production on a daily basis for a minimum of three months Upper airway inflammation and no evidence of bronchial wheezing Evidence of infiltrate on the chest radiograph Evidence of increased interstitial or alveolar fluid on the chest radiograph Typically related to a precipitating Occasion, including smoke inhalation Asthma and allergic bronchospastic disorders, including allergic aspergillosis or bronchospasm because of other environmental and occupational exposures, can mimic the productive cough of acute bronchitis.

- Bronchitis is an inflammation of the lining of your bronchial tubes, which carry air to and from.
- Bronchitis may be either chronic or acute.
- A more serious ailment, chronic bronchitis, is a persistent irritation or inflammation of the lining of the bronchial tubes, often due to smoking.
- Chronic bronchitis is among the conditions contained in chronic obstructive pulmonary disease (COPD).
Lower Respiratory Tract Infection
Lower respiratory tract infection (LRTI), while often used as a synonym for pneumonia, also can be applied to other types of infection including lung abscess and acute bronchitis. Antibiotics are the first line treatment for pneumonia; yet, they are not successful or suggested for parasitic or viral infections. Acute bronchitis can be defined as acute bacterial or viral illness of the larger airways in healthy patients without history of persistent disorder. Treatment of acute bronchitis with antibiotics is common but contentious as their use has just moderate benefit weighted against potential side effects (nausea and vomiting), increased resistance, and price of treatment in a self-limiting illness. Antibiotics can be given to patients with acute exacerbations of chronic bronchitis while acute bronchitis often will not require antibiotic therapy.
Upper Respiratory Tract Infection Symptoms and Treatment
Sinus infection (sinusitis) symptoms can include headaches, a sore throat, and toothaches. Chronic sinusitis may result from allergies and can continue as much as three months. Antibiotics and home remedies can relieve sinus infection (sinusitis) symptoms.
