emergenza influenza
http://it.wikipedia.org/wiki/InfluenzaL'influenza è una malattia contagiosa causata da virus RNA della famiglia degli Orthomyxoviridae. È caratterizzata da sintomi sistemici (febbre non sempre presente, malessere generale, cefalea e dolori osteomuscolari e respiratori, tosse, faringodinia) comuni a molte altre malattie virali. L'esordio è generalmente brusco e improvviso e la febbre dura 3-4 giorni.

From Wikipedia, the free encyclopedia
Influenza, commonly referred to as the flu, is an infectious disease caused by RNA viruses of the family Orthomyxoviridae (the influenza viruses), that affects birds and mammals. The name influenza comes from the Italian influenza, meaning "influence" (Latin: influentia). The most common symptoms of the disease are chills, fever, sore throat, muscle pains, severe headache, coughing, weakness and general discomfort.[1] Fever and coughs are the most frequent symptoms. In more serious cases, influenza causes pneumonia, which can be fatal, particularly for the young and the elderly. Although it is often confused with the common cold, influenza is a much more severe disease and is caused by a different type of virus.[2] Influenza may produce nausea and vomiting, particularly in children,[1] but these symptoms are more common in the unrelated disease gastroenteritis, which is sometimes called "stomach flu" or "24-hour flu".[3]
Typically, influenza is transmitted through the air by coughs or sneezes, creating aerosols containing the virus. Influenza can also be transmitted by bird droppings, saliva, nasal secretions, feces and blood. Infections also occur through contact with these body fluids or with contaminated surfaces. Airborne aerosols may be responsible for most infections, although which of the various means of transmission is most important is not absolutely clear. Influenza viruses can be inactivated by sunlight, disinfectants and detergents.[4][5] As the virus can be inactivated by soap, frequent hand washing reduces the risk of infection.
Flu spreads around the world in seasonal epidemics, resulting in the deaths of hundreds of thousands annually — millions in pandemic years. Three influenza pandemics occurred in the 20th century and killed tens of millions of people, with each of these pandemics being caused by the appearance of a new strain of the virus in humans. Often, these new strains result from the spread of an existing flu virus to humans from other animal species. An avian strain named H5N1 raised the concern of a new influenza pandemic, after it emerged in Asia in the 1990s, but it has not mutated to a form that spreads easily between people.[6] In April 2009 a novel H1N1 flu strain that combined genes from human, pig, and bird flu, initially dubbed the "swine flu", emerged in Mexico, the United States, and several other nations. By late April, the H1N1 swine flu was suspected of having killed over 150 in Mexico,[7] and prompted concern that a new pandemic is imminent. However, confirmed cases were lower, with only 10 deaths by the end of April, 9 in Mexico and only 1 in the US.[8]
Vaccinations against influenza are usually given to people in developed countries [9] and to farmed poultry.[10] The most common human vaccine is the trivalent influenza vaccine (TIV) that contains purified and inactivated material from three viral strains. Typically, this vaccine includes material from two influenza A virus subtypes and one influenza B virus strain.[11] The TIV carries no risk of transmitting the disease, and it has very low reactivity. A vaccine formulated for one year may be ineffective in the following year, since the influenza virus evolves rapidly, and different strains become dominant. Antiviral drugs can be used to treat influenza, with neuraminidase inhibitors being particularly effective.
