Para-influenza virus infections.

The Para-influenza virus causes a group of respiratory illnesses that usually manifest with febrile conditions that affect mostly children. The infection is spread from person to person by contact and possibly by air suspensions. Examples of these diseases are acute upper respiratory illness, and lower respiratory diseases (E.g. acute Bronchitis and Pneumonia), as well as laryngeal trachea bronchitis.

Signs and symptoms include acute febrile episodes which in most cases reach a temperature of about 101 F to 104 F; malaise; Coryza, moderate sore throat and dry cough that usually last for 2 to 3 days. The degree of malaise is directly proportional to the degree of temperature. Also there is Bronchitis and Pneumonia after the onset of acute febrile episode. Croup or laryngeal trachea Bronchitis represents the most severe and dangerous manifestations of the Para-influenza virus.
