Core Tip

Core tip: Acute gastroenteritis has been associated with significant rates of morbidity and mortality among immunocompromised patients. Rotavirus (RV) and adenovirus (AdV) are described as common agents of viral gastroenteritis causing acute diarrhoea. This is the first study in Portugal to characterize the prevalence and seasonal features of RV and AdV infections in immunocompromised patients with acute gastroenteritis. Results revealed 12.4% AdV positive samples and 0.8% RV positive samples, which correspond to a prevalence of 6.5% and 1.5%, respectively. Our results also demonstrate the importance of to add more screening methods for other emergent enteric viruses, in order to avoid the morbidity and mortality of the immunocompromised patients.
