Is swine flu more dangerous than other virus outbreak?

The H1N1 pandemic influenza virus is more virulent than scientists previously believed. The filamentous form of the virus is budded from infected cells. Unlike the run-of-the-mill seasonal flu viruses, H1N1 virus demonstrates the ability to infect cells deep in the lungs, where it can lead to pneumonia and in severe cases, it may lead to death. Seasonal viruses normally infect only cells in the upper respiratory tract. People think that this pathogen may be similar to seasonal influenza. This study shows that is not the case. There is clear evidence that the virus is different than seasonal influenza.

The ability of the lungs to infect is a frighteningly similar to those of the other virus epidemic, especially the 1918-virus which killed tens of millions of people at the end of World War I. And it is possible that the virus could be even more pathogenic than the current pandemic continues its course and the virus is designed to provide new functions.

To assess the nature of the pathogenic H1N1 virus, some researchers inspected groups of mice, ferrets and non-human primates – all generally accepted models for studies of the flu – the pandemic virus and a seasonal flu virus. They found that the H1N1 virus replicates much more efficiently in the respiratory organs as seasonal flu and caused severe damage in the lungs similar to those caused by other types of virulent flu pandemic.

The study also demonstrates the immune response of various groups to the new virus, and, surprisingly, found that people with the virus, which are in advanced age, have neutralizing antibodies to the H1N1 virus.

The study also noted that existing and experimental anti-viral drugs could be an effective first line of defence against the virus and its slow diffusion.

Influenza is a type of virus, and like any virus can often mutate into new forms. It is suspected that what was originally believed that an aggressive strain in Mexico was an erroneous assumption based on lack of complete information on the number of infected people. This made it obvious how the burden in Mexico was very different and more deadly than the strain that the people of the United States.

However, the flu can kill with a compromised immune system, especially the very young, very old, the debilitated, or people with serious chronic diseases. The thing that this makes this strain of flu of more concern is that it is an entirely new strain, so no-one has immunity to it. There have not been flu vaccines developed for it yet and so the potential for wide dissemination of this virus is larger than others.
