Studying new viruses that would be worse than the H1N1
By: El Universal Mexico / El Semanario, on Wednesday, May 13, 2009
The emergence of a mutation or a new influenza virus, which could be more aggressive than the one currently affecting the world, is being examined by health authorities in Mexico, the U.S. and Canada.
The new virus that is under study is of type A, but subtype is not specified. There would be few cases in Mexico, the U.S. and Canada.
According to information from the newspaper El Universal, Miguel Angel Lezana, director general of the National Center of Epidemiological Surveillance and Disease Control said that since Mexico epidemiological alert on April 23 and from the laboratory to be mounted for testing PCR is discussed in this virus that keeps alerting Mexican authorities, as well as the Americans and Canadians.
He explained that the evidence indicates that type A, but did not specify the subtype, adding that the three countries have similar cases, however, did not detail the number of detected infected, and although he acknowledged that few, if known are A H1N1 or H3N2 .
Other officials of the Ministry of Health (SSA) confirmed cases were detected which have reported a mutation or a new virus.
Respect to its new version of the virus may be more aggressive Lezana said: "It is a possibility" and that "the only way to know this is a series of bioassays, and the complete sequence of the gene of the virus, which has been working. "
The steering CENACEVE also said that the isolates are being made in cases of deaths in those who do not, because "it is important to know whether the fact that a person dies and another does not, has to do with the characteristics virus or other factors. "
Finally, he noted that President Felipe Calderón is fully informed of everything. "

Eh, isn't it just telling people that there's a new virus (swine origin H1N1) which is worse than the existing (seasonal) H1N1 / H3N2 viruses? This looks to me like a random newspaper coming very late to the party.

> There would be few cases in Mexico, the U.S. and Canada.
ohh, in 3 countries already ?
and they found it already on 23.April ?
and it's not H1N1 ?
and they didn't tell us ?
what else are they hiding
> President Felipe Calderón is fully informed
he is not a virologist

pjie2, that's not how I understood it
> worse than the H1N1
in the headline
well, maybe it's the translation...
Shiloh wouldn't have posted it, if it were old news ?

Detected mutation, or a new virus
International panel of experts warns that there are 10 times more cases of influenza
The note says
Wednesday May 13, 2009
Health Authorities of Mexico, United States and Canada detected what could be a new version or a mutation of the influenza virus A (H1N1), and not out at the moment that is more aggressive than those currently circulating in the world.
Since the epidemiological alert on April 23 and from the laboratory that was set to run the PCR, "discusses this virus keeps alerting Mexican authorities, revealed the director general of the National Center of Epidemiological Surveillance and Disease Control (Cenavece), Miguel Angel Lezana.
"We have cases where immunofluorescence says is A, but I did not say what subtype. PCR tells me that it is today we have cases like this, and this case is United States and Canada have such cases, "he says. Other officials of the Ministry of Health confirmed cases were detected which have reported a mutation or a new virus.
Lezana did not specify the number of detected infected or the states of the Republic where there were, but said that so far have been few. "Maybe they are human H1N1, H3N2 is the best, we do not know."
The director of Cenavece did not rule out that this new version of the virus is more aggressive than currently circulating. "It's a possibility, the only way to know this is a series of bioassays, and the complete sequence of the gene of the virus, which has been working, we are doing both in sequencing and in these bioassays to compare with experimental animals virulence of this virus with other influenza-like "Lezana revealed, adding:" The insulation we are getting both cases who have died and those who do not, because it is important to know whether the fact that one person dies and another not, has to do with the characteristics of a virus or other factors. "
The official said that in cases where non-subtype has been identified, all patients are alive. "
- Have you told the President?
The president is fully informed of everything.
Meanwhile, a preliminary report prepared by a multidisciplinary group of international scientists, including Mexicans, warned that the number of infected influenza A could have been widespread in Mexico at a rate higher than the Mexican authorities have acknowledged so far. According to the report published in part in the latest edition of the prestigious journal Science, have 23 thousand affected by the epidemic, very far to figure out by the authorities.

Detectan mutación, o un nuevo virus
Panel internacional de expertos advierte que hay 10 veces más casos de influenza
Comenta la nota
Miércoles 13 de mayo de 2009
Autoridades de Salud de México, Estados Unidos y Canadá detectaron lo que pudiera ser una nueva versión o una mutación del virus de la influenza A (H1N1), y no descartan, por el momento, que sea más agresivo que el que actualmente circula en el mundo.
Desde la alerta epidemiológica, el 23 de abril, y a partir de que se montó el laboratorio “para correr las pruebas de PCR”, se analiza este virus que mantiene en alerta a las autoridades mexicanas, reveló el director general del Centro Nacional de Vigilancia Epidemiológica y Control de Enfermedades (Cenavece), Miguel Ángel Lezana.
“Tenemos casos en donde la inmunofluorescencia nos dice que es A, pero no me dice qué subtipo. PCR me dice que es A; hoy tenemos casos así, y Estados Unidos tiene casos así, y Canadá tiene casos así”, asegura. Otros funcionarios de la misma Secretaría de Salud confirmaron que se detectaron casos que refieren una mutación o un nuevo virus.
Lezana no precisó el número de infectados detectados ni los estados de la República en donde se presentaron, pero aseguró que hasta ahora han sido pocos. “A lo mejor estos son A H1N1 humano, a lo mejor son H3N2, no sabemos”.
El director del Cenavece no descartó que esta nueva versión del virus sea más agresiva que la que circula actualmente. “Es una posibilidad; la única manera de saber eso es con una serie de bioensayos y teniendo la secuencia completa del gen del virus, cosa que se ha venido trabajando; lo estamos haciendo tanto en la secuenciación como en estos bioensayos con animales experimentales para comparar la virulencia de este virus con otros de influenza parecidos”, reveló Lezana, y agregó: “Los aislamientos los estamos sacando tanto de casos que han fallecido como de los que no, porque es importante comparar, saber si el hecho de que una persona muera y otra no, tiene que ver con las características propias del virus o con otros factores”.
El funcionario aseguró “que en los casos en que no se ha identificado el subtipo, todos los pacientes están vivos”.
—¿Ya le informaron al Presidente?
—El Presidente está perfectamente informado de todo.
Mientras tanto, un reporte preliminar elaborado por un grupo multidisciplinario de científicos internacionales, entre ellos mexicanos, alertó que el número de infectados por la influenza A podría haberse extendido en México en una proporción más elevada de lo que las autoridades mexicanas han reconocido hasta ahora. De acuerdo con el informe publicado de forma parcial en la edición más reciente de la prestigiosa revista Science, habría 23 mil afectados por la epidemia, cifra muy distante a la confirmada por las autoridades.

The above are today's news report. Was it not the NY Times article about the lack of fever in some patients that mentioned there were different strains in Mexico? The articles above might be referring to those as well as some that may be worse.

In Mexico there is talk of a new mutation or influenza virus
Experts found what could be a new version of the virus or a mutation of influenza A. Do not rule out that it is more aggressive than the one currently affecting the world
Health specialists from Mexico, the United States and Canada detected what could be a new version or a mutation of the influenza virus A (H1N1), and not out to be more aggressive than the current one.
The director general of the National Center of Epidemiological Surveillance and Disease Control (Cenavece) of Mexico, Miguel Angel Lezana, told El Universal that the analysis say it is A, but does not say what the virus subtype belongs. "Today we have such cases, as in the United States and Canada," he said.
Other officials of the Ministry of Health confirmed cases were detected which have reported a mutation or a new virus.
Lezana did not specify the number of detected infected or states where there were, but said that so far have been few. "Maybe they are human H1N1, H3N2 is the best, we do not know."
H3N2 is a subtype of influenza virus that can infect birds and mammals. In birds, humans and pigs, the virus has mutated in many strains. H3N2 is becoming more abundant in the seasonal flu, which kills an estimated 36,000 people in the United States each year.
The director of Cenavece did not rule out that this new version of the virus is more aggressive than currently circulating.
"It's a possibility, the only way to know this is a series of bioassays, and the complete sequence of the gene of the virus, which has been working. Isolates're getting both cases who have died and those who do not, because it is important to know whether the fact that a person dies and another does not, has to do with the characteristics of a virus or other factors, " added.
Reuters reported last week that experts found a strain of the H3N2 virus seems to have changed and could have complicated the picture influenza in Mexico, the epicenter of an outbreak of a new strain of influenza virus H1N1.
This modified strain of H3N2 was seen in a traveler returning from Mexico, as reported the team of the Center for Disease Control in British Columbia Pro-MED, an Internet forum for experts in infectious diseases.
Scientists believe that the strain might have been involved in the outbreak of influenza occurred unusually late this year in that area of the northern hemisphere.

Mutation of influenza A, greater than that of HIV-Ssa
Notes Health Secretary Jose Angel Cordova a theory about the disease is likely that the virus has mutated to either have two different characteristics, which one would be more aggressive and in some other, benign
MEXICO CITY WEDNESDAY 13 MAY 2009
Jose Angel Cordova, Secretary of Health, said that the mutation of the human influenza virus is larger than that introduced the Human Immunodeficiency Virus that causes AIDS.
He explained that studies are conducted at this time is from two different types of viruses that emerged from it.
The official said that so far is a "probable theory in which the human influenza virus has mutated, or has characteristics in two different viruses, which one would be more aggressive in some patients and in others completely benign."
At a press conference the Secretary also presented the final report of the evolution of this epidemic and reported that so far is two thousand reported cases of 446 people who contracted the virus, 60 of whom died.
He said that San Luis Potosí, Zacatecas, Hidalgo, Estado de Veracruz and Mexico are the entities that reported the highest incidence of people with the disease, while 89% said the country's municipalities have no confirmed cases.
Baja California Sur, Coahuila, and remain so far without any record.
He said that in the case of tourist destinations, Cancun, Acapulco and Huatulco cases of people with the virus, but said that at this stage the frequency of these indicate that there is no risk in visiting these places if the measures are maintained which has recommended the agency.
Towards children who have been monitored in schools through the school filters, José Ángel Córdova announced Tuesday that 77 thousand children were detained for several of the symptoms of respiratory diseases, such as fever, cough, nasal and headache.
In this regard, he noted that the Secretariat of Public Education (SEP) has received complaints and irregularities on the part of parents, then to say that their children had nasal allergies. "This is difficult to distinguish, but they have to do."
