life of a virus

Maybe you have heard about the Spanish flu from your grandparents. It affected Europe during 1918, at the end of the WW2, making millions of victims.

It is believed that this virus was also based on the h1n1 strain, just like the swine flu, but as the medical methods used then were not as accurate as they are today, this information can’t be confirmed. The virus had nothing to do with Spain, as the pandemic virus had the same impact over all the Occidental countries of Europe. It was called the Spanish flu, as the Spanish newspapers were the only free media methods speaking about it, while the newspapers from other countries were censored by the war propaganda.

The lifecycle of h1n1

The swine flu, just like the Spanish or Avian virus, has about the same lifecycle. In fact, the lifecycle of a pandemic virus was first studied with the Spanish flu, and the results are about the same and valid even today.

The h1n1 virus appears at animals, because improper conditions or because the food given to those animals. At first, the virus stays in a latency form, and it is harmless for the respective animals. The danger in this case is the fact that those animals can survive for months, and during this time, the viruses can easily develop strong stains that are immune to vaccines. For example, in the case of swine flu, the farmers believed that this was a simple virus, therefore they started to vaccine the animals with different solutions. Of course, those solutions were not effective. On the contrary, the virus developed immunity to those simple vaccines, giving the pandemic side of the disease. In the case of the Spanish flu, there are no sure details about the development of this disease, but in the case of the modern pandemic diseases, it is confirmed that this was the first and most important mistake made in the treatment of this disease.

Transmitting h1n1 from animals to humans

Just as the Spanish flu had nothing to do with Spain, the swine flu has nothing to do with pigs. It is true that this virus can be transmitted from pigs, but the chances are just about the same for this pandemic condition to be transmitted from other animals. Just like in the case of the Spanish flu, as soon as the h1n1 is transmitted to humans, it suffers modifications that make it stronger and more powerful.

Even if researchers developed some vaccines against the swine flu, this virus can be treated most effectively with rest and treating the symptoms. The pandemic flue usually disappears by them, but in some rare cases, it could result in the decease of the diseased person. With the modern medical methods, the impact is smaller than the one of the Spanish flu, but people continue to die because of those diseases.

H1n1 finds a great environment to develop for humans. The organisms are less resistant than those of animals, allowing the swine flu not only to develop as a powerful virus, but also to suffer mutations and to be transmitted to other humans.

What are the most exposed categories of people to the pandemic diseases?

The complications can appear to fragile persons, old or ill persons, but also to children and people with a weakened immune system .The Spanish flu found a large number of people with a weakened system after the First World War, and it had a great environment to develop. Even if the h1n1 is considered a more powerful virus, the modern vaccines allow people to protect themselves effectively. Unfortunately, the swine flu is known as a virus with a huge potential to adapt and to develop the necessary modifications needed to adapt to any kind of environment. In fact, this adaptability gives the pandemic character of the swine flu, just like in the case of the Spanish flu.

What happens when the swine flu virus develops in humans?

H1N1 develops in different ways once it is installed in humans. It can survive for one week or more, and the response of the human organism is different, considering the immune resistance of different people to the swine flu. If the organism is weakened, the flu affects all the weak organs, killing the host eventually. If the organism is strong, it will manage to fight the virus, eliminating it. In any case, the virus dies one way or the other, and even if the bodies might be contagious for a while, the virus eventually dies.
