A study by researchers at Columbia University and the Harvard School in the United States has revealed that The girl, a meteorological phenomenon that occurs in the tropical area of ​​the Pacific Ocean at approximate intervals of two to seven years, and that lasts several months, interferes with the migratory patterns of birds, altering them, and that this has the consequence that they develop new dangerous strains of virus of the flu, responsible for the pandemics.

To reach this conclusion, scientists have studied the climatic conditions that preceded the severe influenza pandemics occurred in the years 1918, 1957, 1968 and 2009, which affected a large number of people, and had a high rate of mortality, and have observed that, in all cases, the ocean temperatures recorded in the equatorial Pacific were lower than the usual average in the months prior to the spread of the disease.

The pandemics analyzed occurred because the influenza genome had changed significantly. According to several researches cited by the authors of the study, the climatic model established by La Niña, modifies the migratory pattern of birds (main reservoirs of human influenza) and changes the habits of these animals, facilitating that different species come into contact and they mix and, as a consequence, new, more virulent strains of influenza develop, which gave origin to these four pandemics.

The New Flu (November 2019).
