Insights
Adenovirus causes viral diarrhoea in young children globally. In Tunisia, enteric adenovirus types 40/41 were identified in over half of adenovirus-positive paediatric stool samples, highlighting their role in childhood illness.
Area of Science:
- Virology
- Epidemiology
- Pediatrics
Context:
- Viral diarrhoea is a significant global health concern for children.
- Four main viral categories (rotavirus, astrovirus, adenovirus, calicivirus) are clinically important.
- Adenovirus, particularly species F types 40 and 41, is a key pathogen.
Purpose:
- To investigate the prevalence and role of adenovirus, specifically enteric adenovirus types 40/41, in acute paediatric diarrhoea in Tunisia.
- To assess the clinical symptoms associated with adenovirus infections in children.
- To evaluate the utility of diagnostic techniques for viral gastroenteritis.
Summary:
- A retrospective study analyzed 638 stool samples from Tunisian children under 5 with acute diarrhoea (Oct 2003-Sep 2005).
- Immunoenzymatic assay (EIA) and ELISA detected adenovirus in 6% of samples; 57% of these were species F adenovirus types 40/41.
- Diarrhoea, vomiting (89%), fever (53%), and respiratory issues (32%) were common symptoms.
Impact:
- Enteric adenoviruses are significant contributors to paediatric diarrhoea in Tunisia.
- Implementing rapid viral diagnostic methods in hospitals can improve patient management.
- Reducing unnecessary antibiotic use through accurate viral diagnosis is crucial for effective healthcare.
Abstract:
Viral diarrhoea remains a major cause of childhood morbidity and mortality worldwide. Four major categories of viruses are now recognized as clinically important, including rotavirus, astrovirus, adenovirus, and calicivirus. This retrospective epidemiological study was conducted in the East centre part of Tunisia. A total of 638 stool samples were collected from children under 5 years of age presenting with acute diarrhoea at hospitals the East centre part of Tunisia between October 2003 and September 2005. All samples were analyzed using commercially available immunoenzymatic assay (EIA) kits to detect specific adenovirus antigens. Samples positive for adenovirus antigen were further screened using an ELISA technique allowing specific detection of species F enteric adenovirus types 40 and 41. Adenovirus was detected in 6% of the stools tested using ELISA. Among stool samples testing positive for adenovirus, 57% (20/35) were found to contain species F adenovirus types 40/41. In addition to diarrhoea that was present in all children studied, vomiting and fever were observed in 89% and 53% respectively and were associated with respiratory troubles in 32%. Enteric adenoviruses appear to play an important role in paediatric diarrhoea in Tunisia. Use of simple effective viral diagnostic techniques in paediatric hospitals could improve patient care by reducing unnecessary use of antibiotics.

Acute Pharyngitis
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.
Classification
Acute pharyngitis can be categorized based on its underlying cause:
Respiratory Syncytial Virus Disease
Cholera
