However, there are still possible side effects associated with AdV-based vaccines. HAdVs are common isolates in young children with pneumonia. HAdV antigen has been identified by immunofluorescence in exfoliated bladder cells. Adenovirus This is often because It is less prevalent than rotavirus infection, occurs most often in children younger than 4 years of age, and is not easily distinguishable from other infectious gastroenteritis based on clinical manifestations. As the infection progresses, the characteristic smudge cells become more apparent and abundant with larger and more basophilic inclusions, and the margins of the nuclear membrane become less distinct [Fig. Often adenovirus affects the respiratory tract (nose, throat, trachea and lungs) causing symptoms like fever, cough and .
