[Rotavirus infection in the older child and adult]

Area of Science:

• Gastroenterology
• Virology
• Epidemiology

Background:

• Rotaviruses are a significant cause of gastroenteritis in infants.
• The prevalence and clinical presentation of rotavirus in older children and adults are less understood.

Purpose of the Study:

• To determine the prevalence of rotaviruses in stool samples from children older than 6 years and adults.
• To identify other enteropathogenic agents in the same cohort.
• To compare the clinical presentation of rotavirus infection in adults with that in infants.

Main Methods:

• Analysis of over 10,000 stool samples.
• Detection of rotaviruses and other enteropathogenic bacteria, including Salmonella and Campylobacter jejuni/coli.

Main Results:

• Rotaviruses were detected in 1.3% of samples.
• Salmonellae (6.3%) and Campylobacter jejuni/coli (1.7%) were the most common enteropathogenic agents found.
• Adult rotavirus infections presented with similar symptoms to infant infections but were generally less severe.
• No correlation was found between rotavirus infection and specific behaviors or eating habits.

Conclusions:

• Rotavirus is an enteropathogen in older children and adults, albeit with reduced severity compared to infants.
• Surveillance for rotavirus and other common enteropathogens like Salmonella and Campylobacter is important in this demographic.
• Further research may elucidate specific risk factors or transmission dynamics in non-infant populations.
