A full-term female neonate was delivered with meconium stained amniotic fluid by cesarean section by a 2009H1N1 positive 22-year-old second gravida mother, who developed symptoms 8 days prior to delivery. The neonate was completely and immediately isolated from the mother after delivery. Oseltamivir was started at birth to the neonate who had a potential possibility of 2009H1N1 infection. At 5 hours of life, the neonate developed respiratory distress. The neonate's throat swab sent for 2009H1N1 by real-time polymerase chain reaction (RT-PCR) assay was positive. The neonate required oxygen by hood for 3 days and made an uneventful recovery. The mother developed acute respiratory distress syndrome after delivery, requiring ventilatory care for 14 days and was discharged after 25 days stay in hospital. 2009H1N1 infection, although rare, needs a high index of suspicion and prompt therapy in neonates. Clinicians should be alert about the possibility of perinatal transmission of 2009H1N1.

Swine influenza virus (SIV) is an important zoonosis pathogen. The 2009 pandemic of H1N1 influenza A virus (2009/H1N1) highlighted the importance of the role of pigs as intermediate hosts. Liaoning province, located in northeastern China, has become one of the largest pig-farming areas since 2016.

Motivation: The coronavirus disease 2019 (COVID-19) pandemic has highlighted the threat of emerging respiratory viruses and has exposed the lack of availability of off-the-shelf therapeutics against new RNA viruses. Previous research has established the potential that siRNAs and RNA-targeting CRISPR have in combating known RNA viruses. However, the feasibility and tools for designing anti-viral RNA therapeutics against future RNA viruses have not yet been established.

Purpose: Studying the cytokine profiles in influenza A pneumonia could be helpful to better understand the pathogenesis of the disease and predict its prognosis. . Patients with influenza A pneumonia (including 2009H1N1, H1N1, H3N1, and H7N1) hospitalized in six hospitals from January 2017 to October 2018 were enrolled (ClinicalTrials.

Highly pathogenic virus infections usually trigger cytokine storms, which may have adverse effects on vital organs and result in high mortalities. The two cytokines interleukin (IL)-4 and interferon (IFN)-γ play key roles in the generation and regulation of cytokine storms. However, it is still unclear whether the cytokine with the largest induction amplitude is the same under different virus infections.
