School Source: http://www.sxc.hu Speaking of virus, you have heard of avian influenza or bird flu? The media inform all the time the concern of farmers, consumers and health authorities with this new epidemic influenza. The disease was first identified in Italy, about 100 years. Believed to be the flu infect only birds until the first human cases were detected in Hong Kong in 1997. At the time, all the birds - around 1.5 million - were killed in three days. This measure was decisively to contain the epidemic. The bird flu has shown a high mortality rate in humans. At 97, six of 18 infected people died. In this new crisis, caused seven deaths were proven virus. For comparison, the Severe Acute Respiratory Syndrome (SARS) has killed 800 people worldwide and infected 8,400 since its introduction in November 2002. Another problem identified: the virus may mutate rapidly and infect other animals. All birds are susceptible to flu, but some species such as ducks, are more resistant. The chickens and turkeys are particularly vulnerable. Eventually, can also be infected pigs. As for the people, they catch the disease through direct contact with infected live birds. The virus is present in the feces of birds that they are dried and pulverized, and then can be inhaled. The virus can survive for long periods in tissue and feces from dead birds, particularly at low temperatures. The symptoms of this disease are similar to other types of flu: fever, malaise, cough and sore throat. Also there have been cases of conjunctivitis. In patients who died, the disease walked to viral pneumonia. There are 15 different variations of the virus, but it is the H5N1 virus that infects humans and can cause death. Among the viruses of this type, variations were found. The viruses analyzed today are also different types seen in the past. (Adapted from: Watch Online, 27/01/04). SEARCH Gave you realize that this virus is not easy!?!? Now is your time to get more information on avian influenza: This disease can be treated? This flu can be transmitted from person to person? We can continue eating poultry? What are the main measures adopted to prevent the spread of this virus? Organization of Living Things

Škola Izvor: http://www.sxc.hu Govoreći o virusu, ste čuli ptičje gripe ptičje gripe ili? Mediji obavijestiti cijelo vrijeme briga poljoprivrednicima, potrošača i zdravstveni stručnjaci s ovom novom epidemije gripe. Bolest je prvi put identificirana u Italiji, oko 100 godina. Vjeruje se da je gripa zaraziti samo ptice dok su prve ljudske slučajevi otkriveni su u Hong Kongu 1997. U to vrijeme, sve ptice - oko 1,5 milijuna - je ubijeno u tri dana. Ova mjera je odlučno u suzbijanju epidemije. Ptičja gripa je pokazala visoku stopu smrtnosti kod ljudi. U 97, šest od 18 zaraženih osoba je poginulo. U ovom novom krizom, izazvao sedam smrtnih su dokazali virusa. Za usporedbu, teški akutni respiratorni sindrom (SARS) je ubio 800 ljudi diljem svijeta, a zaraženo 8400 od njegova uvođenja u studenom 2002. Drugi problem koji je identificiran: virus može mutirati brzo i zaraziti druge životinje. Sve ptice su osjetljivi na gripe, ali neke vrste, kao što su patke, su otporniji. Kokoši i pure su posebno ranjiva. Na kraju, također mogu biti zaražene svinje. Što se tiče ljudi, oni uhvatiti bolest izravnim kontaktom sa zaraženim živih ptica. Virus je prisutan u izmetu ptica koje su osušeni i praha, a zatim se može udahnuti. Virus može preživjeti dugo u tkiva i izmet iz mrtvih ptica, osobito na niskim temperaturama. Simptomi ove bolesti su slične drugim tipovima gripe: povišena tjelesna temperatura, malaksalost, kašalj i grlobolja. Također je bilo slučajeva konjunktivitisa. U bolesnika koji su umrli, bolest išao na virusne upale pluća. Postoji 15 različitih varijacija virusa, ali je H5N1 virus koji inficira ljude i može uzrokovati smrt. Među virusa tog tipa, varijante su pronađena. Virusi danas analizirani su i različite vrste vidjeli u prošlosti. (Preuzeto iz: Gledaj Online, 27/01/04). TRAŽI Dao ste shvatili da je ovaj virus nije lako!?!? Sada je vrijeme da biste dobili više informacija o ptičje gripe: Ova bolest se može liječiti? Ova gripa može prenijeti s osobe na osobu? Možemo nastaviti jesti perad? Koje su glavne mjere usvojene kako bi se spriječilo širenje ovog virusa? Organizacija živih bića
