In the endemic settings of India, high CFR (3.6-7.02%) was observed in the consecutive 2009, 2015 and 2017 A/H1N1pdm09 outbreaks, though in eastern India CFR varied between 0 and 5.5% during same period. Recurrent outbreaks of pandemic Influenza A/H1N1pdm09, fragmented nationwide incidence ...

Background: The global surveillance of influenza has yielded a substantial amount of sequence and antigenic information covering the evolution of the virus. From 2010 to date, The Mexican Emerging Infectious Diseases Clinical Research Network (LaRed) implemented a hospital-based program to study the ...
The substantial increase in prevalence and emergence of antigenically divergent or highly pathogenic influenza A(H7N9) viruses during 2016–17 raises concerns about the epizootic potential of these viruses. We investigated the evolution and adaptation of H7N9 viruses by analyzing available data and newly...
In recent years, most cases of seasonal influenza have been caused by the simultaneous spread of influenza A and B viruses [5]. In temperate climates, influenza typically occurs once a year during the cold season; however, year-round influenza activity can be seen in tropical and subtropical ...
One of the difficulties that has hampered structural studies of influenza virus is that no two virus particles are the same. In this fundamental respect, it differs from other viruses; poliovirus, for example, has a coat that is identical in each virus particle, allowing it to be studied by...
OBJECTIVE: To reveal the basis of molecular biology of the phase change of influenza A (H1N1) viruses. METHODS: Virion RNA was transcribed into cDNA by reverse transcriptase, cDNA amplified by PCR, the products of PCR were purified. Afterward, RNA sequence analysis was performed by the dideoxyn...
Influenza Viruses: The origin of Pandemic Influenza Viruses. Human epidemic influenza is caused by influenza type A and B viruses, which continually undergo antigenic change in their surface antigens, haemagglutinin ... DOWDLE,R W. - 《Science》 被引量: 9发表: 1984年 Summary of the Internationa...
Various viruses, including influenza virus, SARS-CoV, and MERS-CoV, employ TMPRSS2 to cleavage the fusion protein to mediate viral-host membrane fusion. Thus, TMPRSS2 inhibitors have become a promising target for inhibiting virus infection.275,276,277Camostat and Nafamostat mesylate are oral TMP...
