Insights
Human parechovirus (HPeV) 1 infections are common in childhood and frequently cause otitis media. This study also found a link between HPeV1 and cough in children.
Area of Science:
- Virology
- Pediatrics
- Infectious Diseases
Background:
- Human parechovirus (HPeV) 1 is a ubiquitous childhood virus with poorly documented clinical manifestations.
- Prospective cohort study to evaluate symptoms associated with HPeV1 infection in children from birth.
Purpose of the Study:
- To determine the clinical symptoms associated with Human parechovirus (HPeV) 1 infection in a pediatric cohort.
- To investigate the link between HPeV1 and common childhood illnesses like otitis media and cough.
Main Methods:
- Prospective follow-up of 59 children from birth at 3-month intervals.
- Symptom data collected via hospital records and parental questionnaires.
- HPeV1 infection diagnosed by neutralizing antibodies; HPeV RNA analyzed in middle ear fluid and nasopharyngeal samples using RT-PCR.
Main Results:
- Otitis media showed a strong association with HPeV1 infection (OR, 6.14).
- HPeV1 RNA detected in 15% of middle ear fluid samples from children with recurrent otitis media.
- Cough was also associated with HPeV1 infection, though less strongly (OR, 3.67).
Conclusions:
- Human parechovirus (HPeV) 1 infections are common in childhood.
- HPeV1 infection is a significant cause of otitis media and may also contribute to cough in children.
Background:
Human parechovirus (HPeV) 1 is a common virus that infects almost everyone during childhood. Because clinical symptoms are poorly documented, we evaluated the symptoms associated with HPeV1 infection in a cohort of children followed prospectively from birth at 3-month intervals.
Methods:
Symptoms such as fever, cough, those of the common cold, otitis media, and gastroenteritis were determined from hospital records and from questionnaires administered to the parents of 59 children during regular study visits. HPeV1 infections were diagnosed by measuring neutralizing antibodies in follow-up serum samples. Additionally, HPeV RNA was analyzed in middle ear fluid (MEF) and nasopharyngeal aspirate samples from 33 patients with otitis media by reverse-transcription polymerase chain reaction.
Results:
Otitis media showed a clear association with HPeV1 infection-it developed in 50% of the 3-month follow-up periods that yielded evidence for HPeV1 infection but in only 14% of the HPeV1-negative periods (odds ratio [OR], 6.14 [95% confidence interval {CI}, 2.75-13.77]). In children with recurring otitis media, MEF samples were positive for HPeV in 15% of episodes. Cough was also associated with HPeV1 infection, but this association was weaker (OR, 3.67 [95% CI, 1.66-8.09]). Other symptoms were not linked to HPeV1 infection.
Conclusions:
HPeV1 infections are common in childhood and may cause otitis media and cough.

Acute pharyngitis is the inflammation of the back of the throat (pharynx), commonly resulting in a sore throat. It is a frequently encountered condition that prompts individuals to seek medical advice.
