It may seem disturbing that now, in Mexico, is also the type H1N1, but these letters do not mean it

Patio by birds and it seems that the time has come to part of the pigs. For years, bird flu was a threat that had worried and news that appeared sporadically, but it was always a very localized shock. define cloche For a few days sacrificed thousands of chickens define cloche or other birds and it was here. The key was that, although occasionally bird flu entrusted to humans, including those not infected, and the disease is not propagated.
But that has changed in the new flu outbreak define cloche in Mexico define cloche has been given. In this case the origin of birds but have not been pigs, but the main difference is that if the virus is transmitted between people. And when that happens the growing problems with uncontrollable speed.
Of influenza viruses there are three, type A is the most common define cloche and is now spreading for Mexico and the United States. define cloche B is less frequent, although every few years a woman fright, and C is the rarest define cloche of all. But each type can be presented in different strains, depending on the type of protein that has the surface. Remember that the virus is simply a bit of DNA surrounded by a few proteins. These proteins are those that will be used to bind and enter cells infect.
In the case of influenza proteins define cloche are two features, define cloche one called hemagglutinin, and give the symbol H and another called neuraminidase that symbolizes the N. Since the two may have different shapes, are numbered, and why talking about the H5N1 virus type, which is the bird flu, but other times it was the H2N2 as the Asian flu of 1957, and the famous Spanish flu H1N1 1918.
It may seem disturbing that now, in Mexico, is also the type H1N1, but these letters do not mean it is the same virus. Just proteins H and N are the same group. The flu changes a little each year and therefore increasingly need new vaccines and will not know for sure how serious.
This time has passed from pigs to humans. We are two animal species that share among other things, many influenza viruses. Usually do not jump between species, but a mutation (and suffer many viruses) can make to begin infecting ourselves. define cloche The mutation causes a protein of the virus present a slightly modified. This new form allows cells to stick to the previously could not do it. As a key if you change a slightly teeth. Suddenly you can open a different locks before. And sometimes, you can now open the lock is a human lung cell.
The worst course is transmitted between people. Coughing liberated thousands of microdroplets of lung fluid, and these droplets (these aerosols) containing inside a considerable number of virus. When someone inhales in the next breath, infection set in his lungs. define cloche But it can also happen that the droplets are deposited in the lock of a door, the bar where we take the subway or the hand when we greet. Worse, the virus infected emit a bit before beginning to be felt ill and close to home drinking juice, define cloche soup and tea eucalyptus.
The question is, how far will this outbreak? Come to become a pandemic? Well, given the mobility of today is quite likely. In most cases, the United States already exist in New Zelada detected in travelers from Mexico and here has been encountered. The WHO and the CDC are already on alert, and the hazard classification on a scale that goes up to 6, we have a 3. This marks the ease of spread and not the danger of the disease. define cloche Please transmitted between humans but not very easily. But the fact is that we are still at the beginning and many missing data. And actually saw the number of cases would not surprise me soon be in level 4 and that it would be much more serious.
Moreover, the mortality define cloche rate in Mexico is now between 2 and 6%. However, in other places where it has been detected appears to be a milder form. As the flu each year. There are different ways of propagating define cloche virus? Analyzes have to wait to find out more.
However, define cloche as the flu every year is different, occasionally there are great pandemics of this disease. This has happened before and will safely happen again in the future. Perhaps this is the time. Luckily fright that gave us the bird flu are now making better prepared. There are drugs that can help treat. This strain define cloche appears resistant to some of you have, such as amantadine, but is sensitive to others, such as oseltamivir (the
