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.

And the risk is not only from RSV That said, RSV remains a player in some patients (particularly NMD patients) despite palivizumab prophylaxis, highlighting the need for RSV as well as parainfluenza vaccines.
Parainfluenza infection in normal, healthy patients is not a life-threatening disease.
Among those, 175 children positive for any influenza A or B virus; RSV A-B, rhinovirus, adenovirus, metapneumovirus A-B, parainfluenza virus 1 and 3, bocavirus, Mycoplasma pneumoniae, enterovirus, coronavirus OC43, 229E, and HKU1 were shown to be infected dually with influenza A and B viruses.

To our knowledge, there are only two cases reported of pericardial effusion associated with parainfluenza viruses in children and none of them in the neonatal period.
The nucleic acids controls for Influenza viruses A and B, Parainfluenza 1-3, Respiratory Syncytial Virus and Adenovirus were provided by the National Institute of Health (Colombia).
In allogeneic hematopoietic stem cell transplant (HSCT) recipients, parainfluenza (PIV) virus can cause varying spectrum of respiratory illness, ranging from self-limited upper respiratory tract infections (URTI) to severe, life-threatening lower respiratory tract infections (LRTI) [1, 2].
Another member of the Paramyxoviridae family with the same type of genome as RSV is parainfluenza virus (PIV).
To the Editor: Parainfluenza virus 5 (PIV5), family Paramyxoviridae, genus Rubulavirus, was previously known as simian virus 5 because of its discovery in primary monkey kidney cells in 1954 (1).
Background: Although human parainfluenza virus (HPIV) has been determined as an important viral cause of acute respiratory infections (ARIs) in infants and young children, data on long-term investigation are still lacking to disclose the infection pattern of HPIV in China.
