The year 2009-2010 saw H1N1 influenza outbreaks occurring in almost all countries of the world, causing the WHO to declare it a pandemic of an alert level of 6. In India, H1N1 influenza outbreaks were again reported in late 2014 and early 2015. Since then, sporadic cases of H1N1 influenza have been reported. H1N1 influenza usually presents itself with respiratory tract symptoms. In a minority of patients, abdominal symptoms may occur as well. Acute influenza-associated encephalopathy/encephalitis mostly occurs in the pediatric population, whereas in adults, it is a rare complication. The incidence of neurological complications appears to have increased after the 2009 H1N1 influenza A virus pandemic. We would like to draw attention to an adult patient case who initially presented with respiratory symptoms but then deteriorated and developed encephalitis, which is rarely reported. As per literature reviewed by Victoria Bangualid and Judith Berger on PubMed, only 21 cases of neurological complications were found in adult influenza A patients, out of whom 8 had encephalopathy.

Objectives: To investigate the prevalence of nine respiratory viruses and their clinical characteristics in children aged up to 5 years old in the state of Sergipe, Northeast of Brazil in the pre-COVID-19 pandemic period.
Methods: Children with suspected influenza virus infection were included in the study. Clinical samples were screened using real-time quantitative polymerase chain reaction for the diagnosis of adenovirus, parainfluenza (PIV)1, PIV2, PIV3, and human metapneumovirus.

Swine influenza virus invades the host through the respiratory mucosa, which severely restricts the development of the pig breeding industry. To construct monomeric and trimeric vaccines, we developed recombinant Escherichia coli Nissle 1917 (EcN) strains that express the receptor binding site (RBS) of the hemagglutinin (HA) antigen from H1N1 swine influenza virus. After the mucosal immunization of mice, we found that probiotics activated CD40 and CD86 in DCs and increased the levels of IL-4 and IFN-γ secretion by T cells.

During the life cycle of the influenza virus, viral RNPs (vRNPs) are transported to the nucleus for replication. Given that a large number of progeny viral RNA occupies the nucleus, whether there is any host protein located in the nucleus that recognizes the viral RNA and inhibits the viral replication remains largely unknown. In this study, to explore the role of hnRNPH1 in influenza virus infection, we knocked down and over-expressed the hnRNPH1 proteins in 293T cells, then infected the cells with the influenza virus.
