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 colour, you might be more likely to have a bacterial infection 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 Common Infection Causing Irritation and Inflammation
If you suffer from chronic bronchitis, you happen to be vulnerable to developing heart problems along with more severe lung disorders and illnesses, so you should be tracked by a physician. Acute bronchitis is generally caused by lung infections, 90% of which are viral in origin. Recurrent episodes of acute bronchitis, which weaken and irritate bronchial airways over time, can lead to chronic bronchitis.
Viral pathogens are the most common cause of respiratory infection in travelers; causative agents include rhinovirus, respiratory syncytial virus, influenza virus, parainfluenza virus, human metapneumovirus, measles, mumps, adenovirus, and coronavirus. Clinicians also should contemplate innovative 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).
Specific travelers have an increased danger of respiratory tract infection, including children, the elderly, and individuals with comorbid pulmonary illnesses, such as asthma and chronic obstructive pulmonary disease (COPD). Unique situations that could necessitate medical intervention include the following: Vaccines are available to prevent lots of respiratory diseases, including influenza, S. pneumoniae infection, H. influenzae type B infection (in young children), pertussis, diphtheria, varicella, and measles.
Nonviral agents cause only a small part of acute bronchitis diseases, with the most common organism being Mycoplasma pneumoniae. Study findings suggest that Chlamydia pneumoniae may be another nonviral cause of acute bronchitis. The obstructive symptoms of acute bronchitis, as determined by spirometric studies, have become similar to those of moderate asthma. In one study. Forced expiratory volume in one second (FEV), mean forced expiratory flow during the midst of forced vital capacity (FEF) and peak flow values decreased to less than 80 percent of the predicted values in almost 60 percent of patients during episodes of acute bronchitis.
Itchy Throat and Cough Itchiness and irritation in the neck often stands for a desire to cough and hence, these kinds of signs and symptoms are experienced simultaneously. These signs are often accompanied by other signs like runny nose, fever, and headache. However,...
Recent Epidemiologic Findings of Serologic Evidence of C
Pneumoniae infection in adults with new-onset asthma indicate that untreated chlamydial infections may have a role in the transition from the acute inflammation of bronchitis to the chronic inflammatory changes of asthma. Patients with acute bronchitis usually have a viral respiratory infection with transient inflammatory changes that create sputum and symptoms of airway obstruction. Signs of reversible airway obstruction even when not infected Symptoms worse during the work week but often improve during holidays, weekends and vacations Persistent cough with sputum production on a daily basis for at least three months Upper airway inflammation and no evidence of bronchial wheezing Signs of infiltrate on the chest radiograph Signs of increased interstitial or alveolar fluid on the chest radiograph Generally 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 Signs of increased interstitial or alveolar fluid on the chest radiograph Usually related to a precipitating Occasion, for example 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 your lungs. Bronchitis may be either chronic or acute. Chronic bronchitis, a more serious illness, is a constant irritation or inflammation of the lining of the bronchial tubes, often on account of smoking. Chronic bronchitis is among the conditions included in chronic obstructive pulmonary disease (COPD).

Lower Respiratory Tract Infection
Lower respiratory tract infection (LRTI), while frequently 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; nonetheless, they indicated for viral or parasitic diseases or are not successful. Acute bronchitis can be defined as acute bacterial or viral illness of the larger airways in healthy patients without a history of recurrent disease. Treatment of acute bronchitis with antibiotics is common but controversial as their use has just moderate advantage weighted against potential side effects (nausea and vomiting), increased resistance, and cost of treatment in a self-limiting condition. Antibiotics can be given to patients with acute exacerbations of chronic bronchitis, while acute bronchitis often will not need antibiotic treatment.
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 last up to three months. Antibiotics and home remedies can alleviate sinus infection (sinusitis) symptoms.
