The influenza A virus does not tend to mutation
2 hours 16 mins ago
ImprimirEl director of the Center for Brain Research and Emerging Infectious Diseases, Juan Jose Badiola, said Tuesday, during lunch, "Influenza A (H1N1) 'organized by the Club Siglo XXI, which seems" unlikely "that the virus influenza mutate in the future.
"The worst that can happen is to mix with other viruses, but I think this virus is already sufficiently mixed. It is a wonder of nature and, therefore, unlikely to see change," he said.
However, explained that one can never be absolutely sure that there is a mutation as "still could combine with a human virus," ie with seasonal flu, although it is also unlikely given that this year are estimated few cases.
The possibility of recombination with an animal virus, especially influenza, although unlikely, would be the most dangerous. First, because "avian viruses have always been the cause of pandemics, and, secondly, because the avian influenza (H5N1), present in Asian countries, has shown in countries like Indonesia, Egypt and Vietnam difficult to treat.
In a union of H1N1 with H5N1, according to Badiola, "would not leave anything good." "Keep in mind that the avian influenza virus has a fatality rate of 50 percent, with only the influenza A virus incorporating a party would be a very good situation," he said.
However, he believed that "until now there is a favorable element is that in these months the influenza A has behaved in a stable manner" and that has successfully adapted to the human species in an "exceptional". In this regard, the general secretary of Health, José Martínez Olmos, said they are alert all health systems, which means that "in Spain are doing epidemiological surveillance to see if there is some variation in the incidence cases of severe or the patient" . He also said that Spain is pending before a possible variation of the virus to respond as "more consistent" with what is going to need.
THE FOCUS OF INFECTION: USA
The influenza A virus may have formed in the United States since this country's pig industry is very important. There, according to Badiola, the infection is endemic, "it is estimated that 25 percent of caregivers of pork and 10 percent of veterinarians have been infected sometime".
This virus is behaving like a real pig virus, and in his opinion should still be called 'swine flu', but understands the pressure of animal meat producers. It recalled that the virus behaves in such animals from the same Well that is doing it in humans, ie has "little high morbidity and lethality.
In his view, "we had a very lucky because we expected was the pandemic of avian flu. Fortunately that has not happened." Dangerous viruses are those that come from birds which at the moment, and without exception, "have failed to adapt to the human species."
ASSISTANCE IN THE SNS
Moreover, Olmos highlighted the work done by the National Health System (NHS) to a new pandemic, "broadcast live", and that the consequences were unknown. In his opinion, these characteristics have marked "crisis management" and, ultimately, the work done by the different administrations.
"One characteristic that has marked much the policy developed in the management of this crisis has been the willingness of all to have an information strategy for accessibility, accuracy and transparency of information, even when we did not know the answer to certain questions," he said.
In this regard, Badiola said that this pandemic will serve the NHS to learn how to cope with such health scenarios. "We are surrounded on all sides of pathogens, there are 300 diseases transmissible from animals to humans, and there are many viruses that are in countries where we normally, and there is a great movement to globalization, so this serves to be better prepared" he added.
Along the same lines expressed the President of the General Council of Official Colleges of Pharmacy, Spain, Carmen Pena. In his opinion, "this is a great public health problem in which boundaries are worth."
Moreover, Pena was in favor of the work done by the Ministry of Health, as well as decisions regarding the withdrawal of the antiviral drug and its future reinstatement.
Health spokesman of the Popular Party (PP), Mario Mingo asked health professionals an example of professional responsibility to get vaccinated, especially those who have publicly stated their intention not vaccinated. "It would be an example of medical responsibility to their patients to vaccinate most of the population, because the goal is on one hand reduce the spread and, secondly, reduce mortality," he said.
Also, Badiola insisted vaccination and, above all in the risk groups and specialists, as "the best way to prevent an infectious disease is vaccination.

Riddle me this. This story posits that H1N1 tends not to mutate. Anecdotal evidence shows that people are getting sick twice from H1N1. Ergo, H1N1 is mutating around previous strain. Or, It's NOT mutating and people are not developing antibodies and getting sick again. Either way we are screwed.
(Oh, and if either of the above are true, the vax won't work either.)
