Summary
In Ghana, rotavirus infection was studied in rural areas. The G3 genotype was the most common rotavirus strain, with P[4] being the prevalent P type.
Area of Science:
- Epidemiology
- Virology
- Public Health
Background:
- Rotavirus is a leading cause of severe diarrheal disease in infants and young children globally.
- Understanding the circulating rotavirus genotypes is crucial for vaccine development and public health strategies.
- Gastroenteritis remains a significant health concern in rural regions of Ghana.
Purpose of the Study:
- To characterize the G and P genotypes of human group A rotavirus strains.
- To determine the predominant rotavirus strains circulating in the rural Upper Eastern Region of Ghana in 1998.
Main Methods:
- An epidemiological study was conducted on rotavirus-positive samples from patients with gastroenteritis.
- Fifty rotavirus isolates were randomly selected for G and P genotyping.
- Genotyping was performed using a reverse transcription (RT)-PCR assay with a seminested multiplex method.
Main Results:
- The G3 genotype was the predominant rotavirus strain, identified in 78% of the isolates.
- Other identified G genotypes included G2 (14%) and G1 (2%).
- Mixed G infections (G3/G2 and G3/G1) were observed in 6% of samples.
- The P[4] type was the most prevalent P genotype (72.34%), followed by P[6] (21.3%) and P[8] (2.13%).
- Mixed P infections (P[4]/P[6]) were detected in 4.3% of isolates.
Conclusions:
- The G3P[4] genotype combination was likely the most common circulating strain in the studied population.
- These findings highlight the importance of ongoing rotavirus surveillance in Ghana.
- The genotypic diversity observed has implications for the efficacy of rotavirus vaccines.
