Abstract:
Nonparenteral transmission might contribute to human parvovirus 4 (PARV4) infections in sub-Saharan Africa. PARV4 DNA was detected in 8 (0.83%) of 961 nasal samples and 5 (0.53%) of 943 fecal samples from 1,904 children in Ghana. Virus concentrations ≤ 6-7 log(10) copies/mL suggest respiratory or fecal-oral modes of PARV4 transmission.
Insights
Human parvovirus 4 (PARV4) infections in Ghana suggest nonparenteral transmission. PARV4 DNA was found in nasal and fecal samples from children, indicating respiratory or fecal-oral spread.
Area of Science:
- Virology
- Public Health
- Infectious Diseases
Background:
- Human parvovirus 4 (PARV4) is an emerging virus with limited understanding of its transmission routes.
- Sub-Saharan Africa presents unique epidemiological contexts for viral infections.
Purpose of the Study:
- To investigate potential nonparenteral transmission routes of PARV4 in children in Ghana.
- To determine the prevalence and shedding patterns of PARV4 in a pediatric population.
Main Methods:
- A cross-sectional study was conducted involving 1,904 children in Ghana.
- Nasopharyngeal and fecal samples were collected and tested for PARV4 DNA using molecular methods.
- Virus concentrations were quantified to infer transmission modes.
Main Results:
- PARV4 DNA was detected in 0.83% of nasal samples (8/961) and 0.53% of fecal samples (5/943).
- Detected virus concentrations were low, ranging from ≤ 6-7 log(10) copies/mL.
- The presence of PARV4 DNA in both sample types suggests potential respiratory and fecal-oral transmission pathways.
Conclusions:
- Nonparenteral transmission, likely through respiratory or fecal-oral routes, may contribute to PARV4 infections in Ghanaian children.
- Further research is needed to elucidate the specific transmission dynamics and clinical significance of PARV4 in this region.
