Upper Respiratory Infection

Relationship between the Upper respiratory infection and bronchitis

Upper respiratory infection as a Precursor disease

Before some patients suffering from acute bronchitis, they initially suffer from acute upper respiratory tract infection (URI or URTI). These infections are often caused by a virus, approximately 80%, and triggered by cold, wet in the rain, fatigue. Thus, the viruses attack and cause upper respiratory infections.

Upper respiratory infection symptoms in conditions are manifested as:

Common cold - also called acute rhinitis. The patients often have headache, fever, hoarse voice, sneezing, increased nasal discharge and nasal obstruction.

Acute pharyngitis and laryngitis - infection in the throat and pharynx. Patients feel itching and painful burning sensation in throat. Symptoms may also include hoarseness, difficulty speaking, fever, breathing with wheezing sound, a small amount of dry cough. The ENT doctor can see the swollen throat and enlarged lymph nodes. If difficulty swallowing, it suggests a Streptococcal infection.

Herpangina - attributed to the Coxsackie virus A, and common children in the summer. It is a type of pharyngitis, characterized by the gray herpes and the superficial oral ulcers, surrounded by flush.

Pharyngoconjunctival fever - more common in children in the summer, transmitted by swimming. They have an abnormal visual intolerance to light, excess tears due infection in eyes, as well as fever, sore throat.

Tonsillitis - the infection causes fever and chills, swollen tonsils, swollen painful lymph nodes.

Progress and Prognosis: The course of acute upper respiratory infection is generally a few days or a week. In most cases, they are self-limited disease, especially the common cold. However, even the upper respiratory tract infection mild, after viral infection, some patients will subsequently get a second infection in pharynx and throat (bacterial infection), which manifests itself with cough with mucoid, later purulent sputum. The previous headache, fever abate or disappear. Runny nose is likely to continue for several days. Upper respiratory infection can exist alone, may also appear together. If the infection becomes severe and complicated, the symptoms also will be prominent. In this case, the patient should seek medical treatment. Otherwise, acute upper respiratory tract infection is very likely to develop an acute bronchitis, which is the infection of the bronchi within the lungs.

Acute bronchitis

In some cases, acute bronchitis comes from the upper respiratory infections, and inherits some of the symptoms: for example, fever, cough and sputum. At this point, the mucus does not come from the throat, but from the bronchi of the lungs. Some patients, especially with the history of allergies, they may have spastic bronchitis and thus feel shortness of breath and chest tightness. Some abnormal sounds can be heard in their lungs by auscultation by a doctor. Acute bronchitis lasts about 2-3 weeks. Infection should be treated by a doctor,  rather than self-healing just relying on your own body resistance. Otherwise, repeated unhealed acute bronchitis may progress to chronic bronchitis. Chronic bronchitis is usually a long-term lung disease, and difficult to be cured.
