Influenza produced by dry cold air
Tuesday, March 1, 2011
Most flu cases appear in the winter when low humidity.
For decades scientists have tried to respond to a concern that seems to be very simple: Why the Flu?
Several hypotheses attempted to solve this puzzle. For example, the fact that people have a weak immune system does not protect enough in winter, or that people are exposed to too much cold.
However, a new research from Oregon State University (USA) seems to have found a solution.
The possible cause
American scholars seem to have found the culprit of the discomforts: it is the absolute humidity.
According to the researchers, this concept refers to the amount of water in the form of steam fills the air everywhere.
The problem is that moisture spreads as fast as the dust with dry air.
About the Study
The researchers conducted tests with funding from the National Institute of Health, United States, which were carried out under the direction of Jeffrey Shaman, a climatologist, and Marc Lipsitch, an epidemiologist.
Together they analyzed data on the link between influenza and climate over the past 30 years. Thus constructed computer models that enabled them to review how the disease spread.
"We found that we could reproduce the seasonal cycle of influenza very well basically the whole country," Shaman said, adding that if he had a real set of cold, dry air will increase your chances of being given an outbreak.
Future Actions
After the analysis, scientists are now looking for ways to channel their efforts in proving how flu epidemics are determined by the geography of each area.
"Every year, the disease moves around the world. It is not a precise pattern, but there are ways consistent passing from the hot zones to temperate regions," reveals Shaman. In addition it can be concluded that get to use moisture as evidence for understanding these phenomena, it might be easier to determine why flu moves around the world.
Data
The scientists found that when the absolute humidity low, the chances of survival of influenza virus increase, as the number of infections.
