Insights
Human bocavirus (HBoV) was detected in 8% of Iranian children with acute respiratory infections. This finding suggests HBoV is a significant contributor to childhood respiratory illnesses, particularly in younger children.
Area of Science:
- Pediatric Infectious Diseases
- Virology
- Respiratory Medicine
Background:
- Human bocavirus (HBoV), identified in 2005, is increasingly recognized as a cause of acute respiratory infections in children globally.
- Previous studies indicate a worldwide distribution of HBoV, yet data from specific regions like Iran were limited.
Purpose of the Study:
- To determine the frequency and clinical characteristics of HBoV infections in young Iranian children presenting with acute respiratory infections.
- To investigate the seasonal patterns and potential co-infections associated with HBoV in this pediatric population.
Main Methods:
- Nasopharyngeal specimens were collected from 261 children under 5 years old with acute respiratory infections in Rasht, Iran, during the winter of 2003-2004.
- Polymerase chain reaction (PCR) and reverse transcription PCR (RT-PCR) were employed to detect HBoV and other common respiratory pathogens.
- Clinical data, including age and hospitalization status, were analyzed in conjunction with HBoV detection.
Main Results:
- HBoV was detected in 21 (8%) of the 261 children studied.
- The virus was more prevalent in hospitalized children (12%) compared to outpatients (4%) (P < 0.05).
- The majority of HBoV-infected children were under 2 years old (81%), with a notable proportion under 1 year (33%). A seasonal peak was observed in February, suggesting autumn and early winter circulation. Seven children had co-infections with other respiratory viruses like RSV, adenovirus, or influenza A.
Conclusions:
- HBoV is a common pathogen associated with acute respiratory infections in young Iranian children.
- The findings highlight the importance of considering HBoV in the differential diagnosis of pediatric respiratory illnesses, especially in younger age groups.
- Further research is warranted to understand the full clinical impact and epidemiological trends of HBoV in different geographical settings.
Abstract:
Human bocavirus (HBoV), a virus discovered in Sweden in 2005, has been associated with acute respiratory infections in young children and subsequent reports suggest that HBoV may have a worldwide distribution. This report describes the frequency and clinical presentation of HBoV in 261 Iranian children<5 years old with acute respiratory infections attending two regional hospitals in Rasht, Iran in the winter of 2003-2004. Polymerase chain reaction (PCR) and reverse transcription PCR (RT-PCR) were used for the detection of HBoV and other respiratory pathogens from nasopharyngeal specimens. HBoV was detected in 21 (8%) children. Fifteen (12%) of these children were identified among 122 children admitted to hospital and 6 (4%) from 139 outpatients (P < 0.05). Most children with HBoV were less than 2 years (17/21, 81%) and 7 (33%) were less than 1 year old. Although HBoV was identified in all ages it affected slightly older children than the respiratory syncytial virus (RSV). The frequency of the virus varied from 1 (3%) in 40 patients in November to 7 (12%) of 61 in February, suggesting a seasonal pattern during the autumn and early winter. Seven children had co-infections with RSV, adenovirus or influenza A. The relatively high frequency of HBoV suggests that the virus may contribute substantially to acute respiratory infections in children.
