Clinical characteristics and follow‐up of children with norovirus‐associated benign convulsions with mild gastroenteritis

OBJECTIVE: Explore the clinical characteristics and prognosis of children with norovirus (NoV)‐associated benign convulsions with mild gastroenteritis (CwG). METHODS: We retrospectively analyzed the Clinical and laboratory data of children with NoV‐associated CwG admitted to the emergency department of Guangzhou Children's Hospital between January 2019 and January 2020. And patients were followed up for 23–36 months. RESULTS: There are 49 cases met the CwG criteria. Vomiting was the first symptom in 31 (63.3%) patients, and vomiting could be the main or the only gastrointestinal symptom. The mean frequency of seizures was 3.8 ± 2.4 episodes. Most patients (95.9%) experienced seizures that lasted for less than 5 min. Of the 43 (87.8%) cases followed up from 23 to 36 months, only one experienced recurrent convulsions (after rotavirus infection). SIGNIFICANCE: NoV‐associated CwG patients were prone to experiencing more convulsions. However, because most NoV‐associated CwG patients had good prognosis, long‐term use of anticonvulsants are unnecessary.
