The new influenza A(H1N1) has so far mainly affected young people, only few people over 60 years. The clinical presentation is similar to that of ordinary influenza; but nausea, vomiting and diarrhoea seem to be more common Hvad er influenza A? Influenza er en virussygdom, som giver ømhed i muskler og led, hovedpine, hoste og feber mellem 38 og 40 grader.. Der findes overordnet tre influenza-typer A, B og C. Type A er den hyppigste og alvorligste med kraftige symptomer. Den dukker som regel op hvert andet eller hvert tredje år. Influenza A (H1N1 eller H3N2) og fugleinfluenza (H5N1) er eksempler på influenza A. Influensa er en sykdom forårsaket av et virus som tilhører familien orthomyxoviridae.Viruset er et negativt 'sensed' RNA-virus, noe som betyr at viruset må «oversette» sitt genom før nye virusproteiner kan lages.Viruset har en lipidmembran som er avledet fra cellen der viruset ble produsert. Det finnes tre ulike typer influensavirus, A, B og C, som er plassert i hver sitt genus

Type A Influenza: Symptoms, Treatment, and Preventio

Influenza is an acute viral respiratory disease that is often characterized by fever, headache, myalgia, sore throat and cough. Influenza infection is transmitted through respiratory droplets or contact and is clinically indistinguishable from other respiratory viral diseases without laboratory confirmation Influenza (the flu) is a highly contagious disease, usually prevented by vaccination and treated by managing symptoms. Spread by body fluids from infected people, symptoms include a runny nose and sore throat. Flu can affect anyone but is especially serious for babies and older people Influenza infection during pregnancy is associated with increased maternal and perinatal complications. Here, we show that, during pregnancy, influenza infection leads to viral dissemination into the aorta, resulting in a peripheral vascular storm characterized by enhanced inflammatory mediators; the influx of Ly6C monocytes, neutrophils, and T cells; and impaired vascular function
