Swine flu: Your experiences

Face masks are now being worn by people across Mexico as a precaution

Readers in the areas affected by the swine flu outbreak have been sending their accounts to the BBC since the first cases were reported.

The virus - which has so far claimed more than 100 lives in Mexico - has spread, with the first European case confirmed in Spain.

Governments around the world are attempting to prevent it spreading further, amid reports of further infections in the US and Canada.

Below, a selection of BBC readers' comments describe a sense of fear and uncertainty gripping their countries as a result of the spread of the virus.

MONDAY, 27 APRIL, MEXICO AND SPAIN

I'm a doctor responsible for managing vaccines in the northern Mexican state of Nuevo Leon.
Over the last two weeks we started seeing patients with high fever, muscle aches, sore throats and coughs. Those symptoms seemed a bit odd for us, but we didn't diagnose them with swine flu as we didn't know about it.

On Sunday we had our first death in the area. It was someone who came from Mexico City. But we don't have the means to confirm whether it was as a result of swine flu.

More than anything, we lack equipment and laboratory kits. All we can do is look at the symptoms and make a clinical diagnosis.

In the pharmacies, there is no Tamiflu available. They only have another medication and they don't even have enough of that.

So the vaccines we have are not enough we don't have the medication required. People here are not aware that this flu outbreak can kill people.

On behalf of all the medical community in Nuevo Leon I'd like to ask for help to get the medication, so we can treat people.

We need to have the means to diagnose people and, most importantly, the means to offer them treatment.

Dr Vicente Torres, Monterrey, Nuevo Leon, Mexico

I have been trying to purchase face masks for myself and my family - my wife and two children - but haven't been able to get one anywhere.

I have visited six pharmacies in the area and all are sold out. None are expecting deliveries until Tuesday. I am concerned by this and don't think it's good enough, given it's a measure the government is advising.

However, I haven't seen any clear government advice on where people can get masks.
My family and I are all at home and are taking general precautionary measures - such as avoiding any outside contact, going very carefully to the supermarket to do basic shopping and making no unnecessary visits or trips.

I hope the government is being truthful - it certainly appears to be transparent in its information.

The schools are closed, as are public buildings. People have been advised to stay at home and have been instructed with basic health precautions to take.

Jorge, Mexico City, Mexico

Our health minister has just confirmed a positive case in a small town called Almansa, 50 miles from the capital of the province of Albacete, where I live.

There are other suspected cases in the same province. It is very worrying, especially as there are concerns that the numbers of people infected will grow.

The main hospital for the province is here in my town and people will be coming here for treatment.

We have received no further information yet from the authorities, beyond the case being confirmed.

We have just been told to stay calm. Meanwhile, everybody is texting each other asking what next?

Francisco Cebrian, Albacete, Spain

SUNDAY, 26 APRIL, MEXICO

I am a doctor and I work in the State of Mexico. I don't work in the shock team; I am in the echocardiography team, but I do get some news from my colleagues in the hospital. There have been some cases of young people dying from respiratory infections, but this happened before the alert and they were not reported because the necessary tests weren't done. We doctors knew this was happening a week before the alert was issued and were told to get vaccinated. I went to buy some anti-virals for my husband, who is also a doctor, because he had contact with a young patient who presented influenza symptoms and died. I don't think pharmacies stock enough anti-virals.

I understand the government doesn't want to generate panic, but my personal opinion is that they issued the alert too late. Still now, the population is not getting the information they need. We have been out in the street and some people are not wearing face masks and are not taking any preventive measures.
Guadalupe, Mexico City

This is another blow to the tourism industry in Mexico, even though non of the events that is taken place is anywhere near the tourist areas of Cancun, Playa del Carmen or Puerto Vallarta, the news comes across as all of Mexico is affected! After wrong reports of drug related violence, military presence etc. in Cancun, which hurt the industry tremendously, now people think that all of Mexico is affected by a virus that is mostly present in the capital. I guess the problem is that this is a country where the capital carries the same name as the country, thus when people hear news about Mexico, albeit it refers to Mexico City, they assume it is affecting the whole country.

Rainer, Cancun

SATURDAY, 25 APRIL, MEXICO

I'm a specialist doctor in respiratory diseases and intensive care at the Mexican National Institute of Health. There is a severe emergency over the swine flu here. More and more patients are being admitted to the intensive care unit. Despite the heroic efforts of all staff (doctors, nurses, specialists, etc) patients continue to inevitably die. The truth is that anti-viral treatments and vaccines are not expected to have any effect, even at high doses. It is a great fear among the staff. The infection risk is very high among the doctors and health staff.

There is a sense of chaos in the other hospitals and we do not know what to do. Staff are starting to leave and many are opting to retire or apply for holidays. The truth is that mortality is even higher than what is being reported by the authorities, at least in the hospital where I work it. It is killing three to four patients daily, and it has been going on for more than three weeks. It is a shame and there is great fear here. Increasingly younger patients aged 20 to 30 years are dying before our helpless eyes and there is great sadness among health professionals here.

Antonio Chavez, Mexico City

I think there is a real lack of information and sadly, preventative action. In the capital of my state, Oaxaca, there is a hospital closed because of a death related to the porcine influenza. In the papers they recognise only two people dead for that cause. Many friends working in hospitals or related fields say that the situation is really bad, they are talking about 19 people dead in Oaxaca, including a doctor and a nurse. They say they got shots but they were told not to talk about the real situation. Our authorities say nothing. Life goes on as usual here.

Young people are going to schools and universities. Buses and planes go and come from Mexico City as frequently as before. Even with two people dead locally, last night the local baseball stadium was full, mainly with young people. What's really happening? I know vaccines are good for nothing, and if you take care, maybe you won't die, so, why not acknowledge the real situation? I know that the economic situation is not the best, and it will worsen with panic. But panic comes from a lack of information. Many people travel for pleasure or without any real need. Stopping those unjustified trips can help a lot to ease the situation. We must do something!Alvaro Ricardez, Oaxaca City, Oaxaca, Mexico

The truth is that it is very strange, what we are living through here. The streets are empty, we are all staying in our houses. People are only going out to the hospitals, drugstores and to buy food. The great majority have their mouths covered. Concerts, festivals, masses have all been cancelled, the football matches have all been played behind closed doors. On the television and radio, every commercial break contains information on the symptoms, saying that if you have them to go to the doctor at once. Although we have been told to go to work as normal on Monday, I am worried because I am employed at a company where there are many people and believe that it could be highly contagious. They say on the news that the cases that are most critical involve people aged 20 to 50.

Nallely T, State of Mexico

Right now the situation is quite scary. We've never been living under such circumstances and it's caught us completely off guard. We are a developing country so our health system isn't very effective, plus the fact that our city is overpopulated doesn't help much; the government is doing what they can but I don't think it's enough. So the future isn't looking too bright. Everyone is very frightened, there are few people on the streets and we are all trying to be as safe as possible. But not knowing exactly how the virus works and how it can be killed off creates a horrible uncertainty. I'm being pessimistic but that's how most people I've talked to feel. Mariana, Mexico City

It's certainly been very quiet where I'm living in the Historic Centre of Mexico City, whereas normally the centre is almost uncomfortably packed at the weekend. Most people also seem to be wearing the face masks being handed out by the army around the city. There always seems to be a healthy mistrust of the government here, but I wouldn't say I'm sensing a great deal of paranoia or panic. It does seem as though the unprecedented actions being taken by the government to contain the virus don't match with the statistics being provided, however, so there is some doubt as to whether they're just being overly cautious or whether things are a lot worse than what they're telling the public.

Randal Sheppard, Mexico City

Right now, things are far from under control here. All the museums, zoos, and concert venues have been closed. Masses, football games, sporting activities, cultural activities, have all been cancelled. All schools will be closed until 6 May, from kindergarten to university. We don't know what to think, the truth is that the government isn't telling us the truth. This case is worst than we think, some people take this just like a joke but not me, this is serious! Als it seems clear that this illness doesn't appear to be affecting the whole country, just Mexico City, the State of Mexico and San Luis Potosi.

Carla, Mexico City

I work as a resident doctor in one of the biggest hospitals in Mexico City and sadly, the situation is far from "under control". As a doctor, I realise that the media does not report the truth. Authorities distributed vaccines among all the medical personnel with no results, because two of my partners who worked in this hospital (interns) were killed by this new virus in less than six days even though they were vaccinated as all of us were. The official number of deaths is 20, nevertheless, the true number of victims are more than 200. I understand that we must avoid to panic, but telling the truth it might be better now to prevent and avoid more deaths.

Yeny Gregorio Dávila, Mexico City

The situation in Mexico City is really not normal. There is a sense of uncertainty that borders on paranoid behaviour in some cases. At this very moment, Mexican TV is showing how military forces are giving masks to the people in the streets. Moreover the news is sending alarming messages for the audience. Really, the atmosphere in the city is unsettling, a good example: pubs and concerts are being closed or cancelled and people don't haven thorough information. In this city (and country) there is an urgent need for assertive information, no paranoid messages from the government or the Mexican media.

Patricio Barrientos and Aranzazu Nuñez, Mexico City

Massive events have been cancelled at the National Auditorium - Mexico City's largest indoor venue with capacity of 10,000 - which has been closed. Two soccer games have been cancelled at the Olympic Stadium. A sold out game with 70,000 expected attendance will be played behind closed doors. Another game at the famous Azteca Stadium that would draw an attendance of 50,000 will also be played behind closed doors.

Juan Carlos Leon Calderon, Mexico City

It's eerily quiet here in the capital. Lots of people with masks, Facebook communities exchanging gallows humour, everybody waiting to see if schools and universities will stay closed for ten days (as goes the rumour). All masks have been used up, and we are waiting for new supplies.

Dr Duncan Wood, Mexico City

Yesterday in my office it was a bit surreal walking in to see all in blue masks with deep cleansing of computer equipment and surfaces going on. Let's hope it is contained and does not escalate. The local news is reporting 200 fatalities and reports of flu spreading from areas outside of Mexico City. Given the volume of daily commuter traffic on cramped busses and trains, this may not have to be too virulent to be disastrous in human terms. I wonder what controls there will be on flights in and out.

Will Shea, Mexico City

I work for the government as a head of a computer infrastructure operations department. At work we are doing several actions to try not to expose workers. We sent several home. I support the Pumas football team and the very important match with the Guadalajara team will be played behind closed doors. My family and I are going to stay home all weekend. We feel a little scared and confused with the feeling that we are not given being told the truth. Many people think the numbers of dead people is higher than we are being told.

Marcos, Mexico City

The whole city is affected, I have a very bad feeling about this. Two of my friends at work are sick, they were sick for a couple of days, they went to the hospital and they sent them back to work. The doctor told them it was just a flu until Friday when the alarm was spread, then they were allowed to go home. I work in a call centre and I'm worried because there are no windows in the building so it cannot be ventilated and around 400 people work there.

We all have talked to our supervisor but no one has done anything not even sterilise or disinfect the area. We will be sick soon and, well, do the math - 400 can infect at least another two per day. The authorities say there's nothing they can do since it's a private company and I can assure you, the company I work for is not the only one like this in the whole city. Us workers don't have much protection from our government and if we want to keep our jobs we have to go anyway.

Adriana, Mexico City

My sister got influenza like symptoms two weeks ago. She is fine now, thank god, but similar cases have been showing up since two weeks ago. I work for a bank and we were told to take our laptops because there is a high possibility to work from home. I have gone out to buy some face masks.

Ruben Farfan, Mexico City

I'm a college student in Mexico City, and I can only say that the information that the media has provided doesn't seem to be enough, we do not now how serious it is because they have failed to mention it. There have been two ways of responding to this event, the ones that have entered themselves into quarantine claiming that the government is hiding something much more serious, and those who take this as a joke saying that everyone is overreacting. To put a cherry on top all kind of crazy rumours are flying around - that they are going to quarantine Mexico City, that a school and some specific branches of offices and jobs are going to be suspended for days to come, and so on. I wish more info was available, for example how to prevent it? Have there been many deaths? Is there a threat of an epidemic?

Mari A, Mexico City

I didn't hear about the flu epidemic until Friday night at 2330. Yesterday the streets were almost empty compared to a normal Friday afternoon. The media is bombarding the same information over and over again, but the authorities haven't said anything new yet, only that they have enough vaccines for those with the flu and that we should avoid public spaces.

¿La peor pesadilla de México?

El doctor Francis Plummer, director científico del laboratorio microbiológico del Estado canadiense, hace una semana recibió en sus oficinas de Winnipeg una llamada en la que se le solicitaba su ayuda para analizar unas muestras procedentes de México que, aparentemente, estaban relacionadas con un extraño brote de influenza.

Era un viernes, Plummer, es uno de los científicos más respetados en el campo de la microbiología, ha desarrollado todo tipo de vacunas experimentales para hacer frente a pandemias como el SIDA o para combatir virus tan letales como el Ebola, la petición no resultó nada inusual ya que son muchos los que siempre han tocado a sus puertas en busca de respuestas alentadoras que, casi siempre, terminan en pesadilla.

Cinco días después, más de 50 muestras procedentes de México llegaban hasta sus laboratorios. Y en un plazo de 48 horas, que se cumplieron este viernes, las noticias que arrojaron resultados que infundieron la alarma y la preocupación en el equipo científico de Plummer:
“Este es un virus nuevo no sólo para los humanos, sino para el mundo”, dijo ayer Plummer en el acto que el Ministerio de Salud de Canadá convocó para presentar los resultados de unas investigaciones que aún están en fase de pruebas y ensayos y que tienen intrigadas a la comunidad científica internacional.

“Aproximadamente 80% de este virus está relacionado con algunas variedades de influenza norteamericana y el 20% restante es una variedad de la influenza euroasiática que se detectó por primera vez en Tailandia”, dijo Plummer al asegurar que se trata de un virus que “se ha reconfigurado para convertirse en algo totalmente nuevo”.

“¿Cómo, cuándo y dónde ha ocurrido?… Esto es algo que aún no sabemos”, dijo Plummer en alusión al trabajo de investigación que aún tendrá que desarrollarse para descubrir el vector, es decir, el origen del brote que ha golpeado a México con mayor fuerza y que, aparentemente, se ha extendido a EU con ocho casos reconocidos por Centro para el Control y Prevención de Enfermedades (CDC) de Atlanta.

En la rueda de prensa, en la que Plummer presentó a este nuevo virus ante el mundo, estuvieron presentes la Ministra de Salud de Canadá, Leona Aglukkaq, quien nada más iniciar el acto formuló la siguiente declaración: “En Canadá no hemos tenido ningún caso de influenza porcina”.
La aclaración de la Ministra salió así al paso de las versiones que habían adelantado la infección de un ciudadano canadiense que había visitado recientemente México: “El hecho de que alguien haya viajado a México y haya regresado enfermo no significa que se haya infectado con este virus en particular”, aseguró el doctor David Butler-Jones, al descartar un posible contagio desde México.

“Las pruebas en las que descubrimos este virus nuevo se realizaron exclusivamente en las muestras que enviaron las autoridades mexicanas”, enfatizó en referencia a los 16 casos que dieron positivos de las 50 muestras enviadas desde México y para salir al paso del ambiente de preocupación que había atizado la supuesta infección de un canadiense que había visitado México.

“En cualquier caso, nos mantenemos vigilantes y ya realizamos pruebas para comprobar si acaso tenemos algún caso que coincida con el virus que ha brotado en México. Pero por el momento no hay ni uno sólo”, añadió.


Tras el descubrimiento del nuevo virus, equipos científicos de Canadá, Estados Unidos y Canadá trabajan de forma conjunta para tratar de elaborar una ruta de acciones (entre ellas la declaratoria de una alerta) que se coordinan, además con la Organización Mundial de la Salud (OMS) en Ginebra.

“Aún tenemos mucho que descubrir sobre este virus que nos tiene muy preocupados”, aceptó Plummer.

La influenza...


De un día para otro en México tenemos una epidemia: El virus de la influenza porcina, la cual es una mutación, y por lo tanto no hay vacuna aunque si existe cura para esta enfermedad. Algo parecido se vivió en China con la SARS y la gripe aviar que viajó a muchos países en el mundo. Y como aqui en México, todo fué de repente, hay que cerrar escuelas, conciertos, Pumas Chivas a puerta cerrada, hay que lavarse las manos hasta la muñeca y hay que evitar aglomeraciones.

Según la OMS han muerto 60 personas en el país, e incluso algunos alarmistas sin fundamento alguno se han atrevido a decir que el 19% de la población está infectada. ¿Por que tan de repente llega esta epidemia a nuestro país?, ¿porque la reacción de las autoridades es súbita e inmediata?, ¿el gobierno se habrá mostrado indiferente ante el problema y actuó cuando ya estaba la epidemia avanzada?, o ¿se está exagerando el fenómeno y se está aprovechando como cortina de humo, para que la gente deje de poner atención en cosas realmente importante?.

Se pueden deducir muchas cosas, pero si es importante tomar precauciones (sin caer en la paranoia) para no exponernos a riesgos. No es algo muy difícil de hacer: simplemente hay que lavarnos las manos, no asistir a eventos multitudinarios (que de todas formas están cancelados) y en caso de contraer una fiebre súbita con dolores de cabeza, dolor de músculos, cansancio, lagrimeo, dolor de garganta o tos, ir al médico para evita cualquier riesgo, puesto que si es esta enfermedad, al ir a tiempo adecuado se evita cualquier riesgo.

Por otro lado, esta “epidemia” llega en un momento donde se habla sobre la militarización de la frontera con Estados Unidos, llega días después de la reunión de los presidentes de México y Estados Unidos, llega justo en medio de el debate sobre la refinería petrolera. Por lo cual tampoco podemos descartar que se pudiera estar exagerando este fenómeno para ocultar algo, porque por lo que se ve, la paranoia entre la población es mucha, y yo creo que muy exagerada, dado que es una enfermedad curable e inofensiva si se toman las debidas precauciones...

La paranoia comienza a superar a la realidad que es esta epidemia, y es lo preocupante. Porque una sociedad asustada tiende a actuar irracionalmente, y no solo eso, sino que es mas suceptible de ser engañada.

Ya empiezan a surgir algunas teorías, y en Internet, algunos cibernautas encuentran información que podría estar relacionada con este fenómeno. Por ejemplo, este artículo de la CNN donde se da la noticia de que desaparecieron contenedores con muestras de virus relacionados con la gripe en Maryland "hace algunos días".

Se sabe poco y se deduce mucho. Y si bien es muy importante que tomemos nuestras precauciones con respecto a la influenza, también deberíamos tomarlas con respecto a los eventos que estén sucediendo, para que no nos llevemos ninguna sorpresa...

Influenza porcina en México...

El país se encuentran en alerta epidemiológica debido aun brote extemporáneo y agresivo de influenza porcina.

Hasta el momento, las autoridades de la Secretaría de Salud de México se han conducido con el profesionalismo que siempre les ha caracterizado al tratar con brotes de enfermedades infecciosas.

Sin embargo, algo ha fallado al la Secretaría de Salud: La comunicación.

La información únicamente se ha dado por boletines y por declaraciones directas del Secretario de Salud, lo cual ha originado:

-Más dudas.
-Suspicacias.
-La ya tradicional teoría del complot
-etc..etc...

La Secretaría de Salud no ha colocado suficiente información en su página web. Para no copiar y pegar.. accesa a http://www.salud.gob.mx/ descargate los boletines..

SUSPENDEN Feria de San Marcos.. 26 de abril 2009

El gobernador Luis Armando Reynoso Femat, adelantó hoy la clausura de las actividades de la Feria Nacional de San Marcos, luego de confirmar la muerte de dos personas por la influenza porcina en Aguascalientes.

En un mensaje ofrecido desde Palacio de Gobierno, Reynoso Femat anunció que desde este domingo se suspende todo lo programado dentro de la verbena, que inició hace una semana y que acabaría el próximo diez de mayo.'

Ante la emergencia epidemiológica en México, por la presencia del virus de la influenza porcina, el gobierno del estado ha decidido suspender las actividades de la Feria Nacional de San Marcos 2009, procediendo a su clausura este mismo día' refirió.

De forma inédita el mandatario dijo que la decisión se toma para proteger la salud de los ciudadanos, debido a que de manera masiva se congregaban en las diferentes actividades como el palenque, corridas de toros, casino, restaurantes y bares.

Todavía este sábado por la noche la Feria Nacional de San Marcos registró miles de visitantes, tanto de Aguascalientes como de otras entidades y extranjeros, a quienes el mandatario pidió su comprensión y tomar las precauciones que se han ofrecido para prevenir contagios.

Al gobernador lo acompañó en la conferencia de prensa el gabinete de salud del estado y el alcalde Gabriel Arellano Espinosa, e incluso el director del Instituto de Salud del Estado de Aguascalientes (ISEA), Ventura Vilchis Huerta, quien confirmó la muerte de dos personas debido a la epidemia de la influenza porcina.

Detalló que uno de los fallecidos era originario de Loreto, Zacatecas, y murió ayer mientras que este día se registró otro deceso, sin que el funcionario de salud diera más detalles del sexo de esta persona, edad o nombres.

Asimismo informó que todavía hay doce personas hospitalizadas en diferentes nosocomios de la entidad, aunque no reveló el estado de salud de los mismos.'

Teníamos internados a cuatro en el Hospital Hidalgo y uno fallecido hoy; tres en el Hospital Tercer Milenio, cinco en el Seguro Social y uno en Pabellón. El primer fallecido es de Zacatecas y estuvo internado un día', dijo.

Vilchis Huerta dijo que se está realizando una búsqueda entre la población de Aguascalientes, para detectar más posibles casos de influenza, además hizo un llamado a la ciudadanía a acudir a los diferentes centros de salud y hospitales, en caso de tener cualquier síntoma que pudiera ser similar a los de la influenza.

Posibles causas para la extinción humana!!!


Estamos acostumbrados a ver anuncios para proteger animales en peligro de extinción y los grandes movimientos ecológicos que generan para salvar esas especies, pero

¿Qué pasa con los seres humanos?

Animales extinguidos recientemente

Entre los más destacados podemos notar el Tigre de Tasmania también llamado Tilacino, una especie de marsupial que vivía en Australia, tenía una forma muy parecida a los caninos actuales o a una combinación de un perro con un coyote, el nombre viene de que su pelaje asemeja las rayas verticales de un tigre y es de Tasmania.. El ser humano fue la causa de su extinción debido a que lo consideraban una amenaza por ser una ‘competencia’ para las presas del lugar.

La extinción humana

Pensar que el ser humano se extinguirá inevitablemente puede sonar absurdo, si tomamos en cuenta que no tenemos depredadores y nuestras maneras de obtener alimentos no nos proporcionan peligro; además de nuestras costumbres de aseo y supuesta inteligencia.
Expertos aseguran que a la humanidad le quedan alrededor de 10,000 años de vida, mientras que otros aseguran que nos restan 20,000 años. Estos investigadores listan las siguientes posibles causas de el cataclismo.


1. El histórico meteorito

Al igual como la principal teoría de la extinción de los dinosaurios un meteorito podría impactar con la tierra puesto que se ha descubierto que en promedio un gran meteorito impacta con la tierra cada 250,000 años. Este tendría alrededor de 1km de diámetro y aunque algunos humanos podrían sobrevivir nuestra civilización como conocemos (o conocerán) dejara de existir.
2. Supernova o Rayos Gamma

Si estos fenómenos ocurrieran cerca (se refiere a unos cuantos años luz de la tierra) acabarían con nuestra capa de ozono, e incluso podría barrer con la atmósfera, quedaríamos ‘desprotegidos’ ante los rayos y ondas provenientes del espacio y la extinción humana y de muchas otras especies sería inminente.

3. Actividad solar errática

La actividad constante, y más que nada constante es lo que ha permitido que la biodiversidad en la tierra continuara. El sol es nuestra fuente de calor y luz natural. Una superfulguración intensa acabaría en pocas horas con nuestra capa de ozono y tendríamos el mismo trágico final que el de la supernova.
