Bronchitis contagious

BRONCHITIS
Bronchitis can be classified into acute or chronic. Acute bronchitis can be defined as an acute bacterial or viral respiratory tract in healthy patients without a history of recurrent disease. It affects more than 40 per 1000 adults each year and consists of a transient inflammation of the bronchi and trachea large. In most cases it is due to a viral infection, so antibiotic treatment is not indicated for immunocompetent persons. Are no effective treatments for acute bronchitis virus bronchitis.Treatment antibiotics is common, but controversial, because their use is only moderate performance weighed against the possible adverse effects (nausea and vomiting), increased resistance, and the cost of condition self-care. beta2-agonists are sometimes used to relieve cough associated with acute bronchitis. A recent systematic review concluded there was no evidence of their use.

Acute chronic bronchitis are usually caused by an infection does not cause the same virus. 50% of patients colonized by Haemophilus influenzae, Streptococcus pneumoniae, Moraxella catarrhalis o. Antibiotics are only found to be effective if all three of the following symptoms are present: - wheezing, increased mucus volume and purulence. In these cases, amoxicillin 500 mg orally every 8 hours for five days or doxycycline 100 mg orally for five days should be used.

TREATMENT

An important consideration in treating a patient with lower respiratory tract infection is to determine if an antibiotic is needed in all. Many infections are viral, and symptomatic treatment is necessary. If an antibiotic is necessary that the choice of drug depends on the site of infection, disease severity, patient age, presence of other underlying diseases, history of drug reactions and the likely performance of the patient.

Antibiotics will not help many lower respiratory tract infections caused by viruses. Although acute bronchitis is often not need treatment with antibiotics, the antibiotics administered to patients with acute exacerbation of chronic bronchitis. The indications for treatment are increased dyspnea and increased volume or purulence of sputum. The treatment of bacterial pneumonia is chosen taking into account the patient's age, severity of disease and the presence of underlying disease. Amoxicillin and doxycycline are suitable for many lower respiratory tract infections seen in general practice.
