Pensando en ustedes

Ahora que todos han tenido su pavo para el dia de gracias quiero hablarles de la gripe del pollo. Primero que nada decidi contactar algunas personas y averiguar cuanto sabian a cerca del tema y luego contestar algunas preguntas acerca de esto. Me di cuenta que muchos no saben bastante sobre el tema y otros piensan que esta en Asia y pronto va a ir a Africa, donde puede llegar a ser desvatadora. Un estudiante de medicina me dijo que algunos de sus amigos piensan que es una pandmica y que tiene el potencial de contagiar a muchas personas y por supuesto matar a cientos de miles, si no estamos listos. Decidi averiguar que es una influenza pandemica. Una influenza pandemica es una epidemia global la cual puede ocurrir, en un promedio de tres a cuatro veces en cada siglo; donde nuevos virus o subtipos emergen y son rapidamente transmitidos de persona a persona. De todos modos el surgimiento de una pandmica es impredicible. En el siglo veinte se tubo la gran influenza pandemica de los anos 1918-1919, la cual causo aproximadamente entre 40 a 50 millones de muertes en todo el mundo, esta fue seguida por una pandemica en 1957-1958 y en 1968-1969. Algunos expertos estan prediciendo que otra influenza pandemica va a ocurrir en un futuro cercano. Sabemos que hay muchas noticias acerca de las investigaciones que se estan haciendo para producir una vacuna para esta enfermedad. Pienso que es importante que estemos informados para estar alertas y esperemos que este bajo control y no se propague a ningun otro pais del mundo. Algunas de las preguntas que tenemos que contestar son: Que es la influenza aviar o de la aves? Esta es una enfermedad infecciosa de pajaros causada por el virus de influenza de tipo A. Es esta una enfermedad nueva? No, esta fue identificada por primera vez en Italia mas de 100 anos atras y ocurrio en todo el mundo. Cuales son los sintomas que presentan los pajaros infectados? La infeccion causa desde una enfermedad simple a una muy contagiosa, rapidamente fatal, resultando en epidemias severas. Que tipo de ave esta propagando el virus? Golondrinas migratorias, y patos silvestres son los mas notables en tener reservas del virus y estos pajaros son tambien los mas resistentes a la infeccion. Las aves domesticas, como pollos y pavos son particularmente suceptibles a las epidemias de influenza rapida y mortal. El contacto directo o indirecto de aves domesticas con golondrinas migratorias ha sido la causa de epidemias frecuentes. Los mercados de aves vivas tambien han jugado un papel importante en la propagacion de las epidemias. Lo que alarmo a muchos fue que normalmente el virus de la influenza aviar no infectaba a otras especies, solamente a pajaros y puercos. La primera infeccion documentada de humanos con el virus ocurrio en Hong Kong en 1997, cuando 18 personas tubieron una enfermedad respiratoria grave, de las cuales seis murieron. La infeccion en humanos coincidio con la epidemia patogenica de la influenza aviar, causada por el mismo virus en la aves de Hong Kong. Una investigacion extensiva determino que el contacto cercano con aves infectadas vivas fue la fuente de la contaminacion en humanos. Hubo una transmicion limitada entre los trabajadores del cuidado de la salud pero no causo casos graves. Ellos decidieron destruir rapidamente, en tres dias, toda la poblacion avicola de Hong Kong, estimada alrededor de 1 millon y medio de aves, esto redujo las posibilidades de transmiciones futuras a personas y puede que esto haya ayudado a prevenir una pandemica. La alarma mas reciente ocurrio en Enero del 2004, cuando los resultados de un laboratorio confirmaron la presencia del virus de la influenzar aviar en casos de enfermedades respiratorias severas en la parte Norte de Vietnam. Toda esta informacion inspira a continuar o empezar a bendecir los alimentos antes de comer, no le parece? Esperemos que el virus no salte, nade o vuele sobre algunos de los oceanos y que toda huella del virus pueda desaparecer. Al mismo tiempo se recomienda comer saludablemente, siempre y lavarse las manos con frecuencia. Estoy al 513-0900 o al sleavitt Avian Influenza (Bird Flu) Now that we’ve all had our turkey for thanksgiving I want to talk about bird flu. First of all, I decided to contact some people and find out how much they know about the subject and then answer some questions about it. I just found out many don’t know that much, and others think that it’s in Asia and will soon go to Africa, where it can be very devastating. One pre-med student told me that some of her friends think that it’s a pandemic and has the potential to hit many people and, of course, kill hundreds of thousands if we are not ready. I decided to find out what a pandemic is. An influenza pandemic is a global epidemic that can be expected to occur, on average, three to four times each century when new virus subtypes emerge and are readily transmitted from person to person. However, the occurrence of influenza pandemics is unpredictable. In the 20th century, the great influenza pandemic of 1918 1919, which caused an estimated 40 to 50 million deaths worldwide, was followed by pandemics in 1957 1958 and 1968 1969. Some experts agree that another influenza pandemic is going to occur some time in the near future. We know that there is a lot of news regarding the research that is being done to come up with a vaccine for it. I think it is important that we know about it and stay alert. Hopefully, it will be under control and it will not be spread to any more countries around the world. Some of the questions that we should answer are: What is avian influenza? This is an infectious disease of birds caused by type A strains of the influenza virus. Is this a new disease? No, this was first identified in Italy more than 100 years ago and occurs worldwide. What are the symptoms that infected birds present? The infection causes mild illness to a highly contagious and rapidly fatal disease resulting in a severe epidemic. What kinds of birds are spreading the virus? Migratory waterfowl – most notably wild ducks – are the natural reservoir of avian influenza viruses, and these birds are also the most resistant to infection. Domestic poultry, including chickens and turkeys, are particularly susceptible to epidemics of rapidly fatal influenza. Direct or indirect contact of domestic flocks with wild migratory waterfowl has been implicated as a frequent cause of this disease. Live bird markets have also played an important role in its spread. The thing that alarmed many was that avian influenza viruses do not normally infect species other than birds and pigs. The first documented infection of humans with an avian influenza virus occurred in Hong Kong in 1997, when there was a severe respiratory disease in 18 humans, six of whom died. The infection of humans coincided with an epidemic of highly pathogenic avian influenza, caused by the same strain, in Hong Kong’s poultry population. Extensive investigation determined that close contact with live infected poultry was the source of human infection. Studies at the genetic level further determined that the virus had jumped directly from birds to humans. Limited transmission to health care workers occurred, but did not cause severe disease. They decided to rapidly destroy — in three days — Hong Kong’s entire poultry population, estimated at around 1.5 million birds. This reduced opportunities for further direct transmission to humans, and may have helped to prevent a pandemic. The most recent cause for alarm occurred in January 2004, when laboratory tests confirmed the presence of avian influenza virus in human cases of severe respiratory disease in the northern part of Vietnam. All of this information should inspire us to continue or start blessing our food before we eat, don’t you think? Let’s hope the virus doesn’t jump, swim or fly over any ocean and hopefully, all traces of virus may disappear. In the meantime it is recommended to keep eating healthy and wash your hands as often as you can. I’m at 513-0900 or at sleavitt
