Abstract

Abstract Backgrond: The population is generally susceptible to influenza A, while neonatal cases are relatively rare.The study aims to explore the clinical characteristics, diagnosis, treatment, and prognosis of neonates with influenza A. Methods: The clinical data from neonates with influenza A who were treated in the neonatal department of Beijing Ditan Hospital affiliated with Capital Medical University from November 2017 to January 2019 were retrospectively analyzed. Results:A total of 9 neonates with influenza A were admitted and treated, with a distribution of 7 males and 2 females. The onset was 1.44 ± 1.46 days (mean ± SD), and age at diagnosis was 21.44 ±6. 53 days. All cases had a history of exposure to febrile patients, The main symptoms are fever, nasal congestion, runny nose, sneezing, coughing, other respiratory symptoms and digestive symptoms such as vomiting milk, choking milk, less milk, diarrhea. Laboratory tests showed 7 cases of decreased white blood cell counts, 3 cases of increased plasma C-reactive protein concentrations. All cases were administered antiviral therapy on the day of admission. Eight neonates reverted to a normal temperature within 48 hours after hospitalization, one neonate’s temperature returned to normal after 48 hours of hospitalization, and all cases’ symptoms gradually improved. Conclusion: The symptoms of influenza A in neonates are atypical, once a diagnosis is confirmed, the prognosis is likely to be favorable as long as antiviral treatment with antiviral is initiated as soon as possible.
