infections are responsible for a large proportion of pneumonias in
preschool children. However, little is known about the prevalence of
X-ray detected pneumonia in different viral LRTI, which sometimes
result in unnecessary treatment. With the availability of the viral
detection diagnostics it becomes possible to characterize the clinical
pictures of different respiratory pathogens. The aim of our study was
to find the prevalence of pneumonia in different viral LRTI.
Nasopharyngeal swab was taken from 278 preschool children with signs or
symptoms of LRTI and the genome of 10 most common respiratory viruses
was detected with the Polymerase Chain Reaction (PCR) based diagnostics.
Altogether 198 (71.2%) of samples were positive. Frequencies of
isolates is shown in
. X-ray detected pneumonia was present in
coronavirus infections, 70% of metapneumovirus infections, 38.9% of
parainfluenza infections, 33.3% of respiratory syncytial virus
infections, 23.1% of adenovirus infections, 13.6% of bocavirus
infections and 7.7% of rhinovirus infections (p<0.01). There was
no difference in the prevalence of pneumonia between single, double or
triple infections (p=0.87).
Some respiratory viruses, such as coronavirus and metapneumovirus are
typically associated with the presence of pneumonia, which does not
mean the bacterial cause of infection. Further studies are necessary
for characterization of different viral LRTI.
