Parainfluenza

 

(also paragrippe), an acute viral disease of the respiratory tract. The disease is transmitted from an infected person by airborne droplets resulting from coughing, sneezing, or talking. It is responsible for a substantial proportion of all viral infections of the respiratory tract.

Parainfluenza affects primarily children. It displays no seasonality. The incubation period is one to six days. The disease begins with rhinitis and a normal or slightly elevated bodily temperature. Inflammation of the larynx, manifested by a sore throat and dry cough, is typical. In some cases, especially in patients with chronic diseases, parainfluenza is complicated by bronchitis and pneumonia. It does not leave a stable immunity. Treatment is symptomatic. No specific preventive measures have been worked out, but the nonspecific preventive measures are the same as for influenza.

All samples were simultaneously screened for influenza viruses (A, B, and C), human parainfluenza viruses (1-4), respiratory syncytial virus, human coronaviruses (229E, NL63, HKU1, and OC43), metapneumovirus, adenovirus, and rhinovirus (6).
Respiratory viruses were identified by individual reverse transcription-PCRs or PCRs selective for RSV; influenza viruses A and B; human parainfluenza viruses 1, 2, and 3; human coronavirus; human metapneumovirus; adenovirus; human bocavirus; picornavirus; and the [beta]-actin gene (9).
Serum was negative for acute infection with flaviviruses (dengue and Japanese encephalitis viruses); alphaviruses (chikungunya virus); influenza viruses; human parainfluenza viruses 1-3; measles, mumps, and rubella viruses; enteroviruses; Bartonella henselae; rickettsiae (R.
Each specimen was tested for the presence of common respiratory viruses: human parainfluenza viruses 1-4, influenza viruses, respiratory syncytial virus, enteroviruses, human coronaviruses (229E, NL63, HKU1, and OC43), metapneumovirus, adenoviruses, and bocaviruses.
