Return of pandemic H1N1 influenza virus
BACKGROUND Influenza pandemics are usually caused by the re-assortment of several influenza viruses, results in the emergence of new influenza virus strains that can infect the entire population. These pandemic strains, as well as seasonal influenza viruses, are subjected to extensive antigenic change that has, so far, prevented the generation of a universal vaccine. METHODS Samples of patien...
متن کاملA novel risk factor for a novel virus: obesity and 2009 pandemic influenza A (H1N1).
BACKGROUND many critically ill patients with 2009 pandemic influenza A (H1N1) (2009 H1N1) infection were noted to be obese, but whether obesity, rather than its associated co-morbidities, is an independent risk factor for severe infection is unknown. METHODS using public health surveillance data, we analyzed demographic and clinical characteristics of California residents hospitalized with 20...
متن کاملThe transmissibility and control of pandemic influenza A (H1N1) virus.
Pandemic influenza A (H1N1) 2009 (pandemic H1N1) is spreading throughout the planet. It has become the dominant strain in the Southern Hemisphere, where the influenza season has now ended. Here, on the basis of reported case clusters in the United States, we estimated the household secondary attack rate for pandemic H1N1 to be 27.3% [95% confidence interval (CI) from 12.2% to 50.5%]. From a sch...
متن کاملNovel swine influenza A/H1N1 and the phase six pandemic.
The family Orthomyxoviridae consists of Influenza A virus which is negative sense single stranded virus. The genome of the virus is segmented and possesses a peculiar trait of genetic reassortment. The influenza virus on its envelop consists of the antigenic glycoprotein like haemagglutinin (HA) and neuraminidase (NA). The changes in those glycoprotein components due to antigenic shift and anti...
متن کاملVirus shedding and environmental deposition of novel A (H1N1) pandemic influenza virus: interim findings.
BACKGROUND The relative importance of different routes of influenza transmission, including the role of bioaerosols, and ability of masks and/or hand hygiene to prevent transmission, remains poorly understood. Current evidence suggests that infectious virus is not typically released from adults after 5 days of illness, however, little is known about the extent to which virus is deposited by inf...
