Pandemic H1N1 influenza virus is of global health concern and is currently the predominant influenza virus subtype circulating in the southern hemisphere 2010 winter. The virus has changed little since it emerged in 2009, however, in this report we describe several genetically distinct changes in the pandemic H1N1 influenza virus. These variants were first detected in Singapore in early 2010 an...
Background. Influenza causes various seasonal respiratory diseases, resulting in significant morbidity and mortality children. is a highly contagious disease causing global pandemics. This study aimed to investigate the frequency outcome of influenza children admitted Tabriz Children's Hospital. Methods. cross-sectional included suspected patients Medical Center between 2014 2019 diagnosed with...
BACKGROUND Among influenza viruses, type A viruses exhibit the greatest genetic diversity, infect the widest range of host species, and cause the vast majority of cases of severe disease in humans, including cases during the great pandemics. The hemagglutinin 1 (HA1) domain of the HA protein contains the highest concentration of epitopes and, correspondingly, experiences the most intense positi...
Waterfowl from northwestern Minnesota were sampled by cloacal swabbing for Avian Influenza Virus (AIV) from July-October in 2007 and 2008. AIV was detected in 222 (9.1%) of 2,441 ducks in 2007 and in 438 (17.9%) of 2,452 ducks in 2008. Prevalence of AIV peaked in late summer. We detected 27 AIV subtypes during 2007 and 31 during 2008. Ten hemagglutinin (HA) subtypes were detected each year (i.e...
Background and Objective: Adamantanes, amantadine, and rimantadine have been used for many years for prevention and treatment of influenza virus A infections. These drugs are influenza virus M2 protein inhibitors and some amino acids substitutions in transmembrane portion of this protein cause resistance to them. This study was done for survey of adamantane resistance related nucleotide sequenc...
Coronavirus disease 2019 (COVID-19) is a contagious caused by newly discovered coronavirus strain. Anxiety, anticipation, and lack of knowledge in the previous experience on severe acute respiratory syndrome (SARS) influenza A virus subtype H1N1 (H1N1) pandemic have substantial impact significant public health behaviours including wearing face mask spaces. We investigate prevalence usage its as...
BACKGROUND Influenza data gaps in sub-Saharan Africa include incidence, case fatality, seasonal patterns, and associations with prevalent disorders. METHODS Nasopharyngeal samples from children aged <12 years who were admitted to Kilifi District Hospital during 2007-2010 with severe or very severe pneumonia and resided in the local demographic surveillance system were screened for influenza A...
Influenza A virus (H1N1), a genetic reassortment of endemic strains of human, avian and swine flu, has crossed species barrier to human and apparently acquired the capability of human to human transmission. Some strains of H5N1 subtype are highly virulent because NS1 protein inhibits antiviral interferon α/β production. Another protein NS2 mediates export of viral ribonucleoprotein from nucleus...
During the 20th century, indisputable pandemics of influenza occurred in 1918, 1957, and 1968. The pandemics of 1957 (A/H2N2) and 1968 (A/H3N2) were associated with major antigenic changes in the virus, probably reflecting introduction by recombination of animal virus genes. The 1918 epidemic is beyond the reach of modern virology but, based on seroarcheology, appears to have been caused by a v...
BACKGROUND Both influenza A virus (IAV) and respiratory syncytial virus (RSV) cause acute respiratory infection (ARI) in infants and young children. This study was conducted to determine Influenza A virus and its co infection with RSV among the hospitalized children with ARI. METHODS A total of 153 throat samples of the hospitalized young children aged between below one year and 5 years with ...
