A study was conducted by researchers at the Aquaculture Biotechnology Center (CBA) and the Faculty of Chemistry and Biology, at the University of Santiago, Chile.
According to Dr Mario Tello, the results of this study are one of the first hypotheses to explain why a highly variable region of the virus, called HPR (High Polymorphism Region English) would be associated with the virulence observed.
"Our results suggest that there is a region of the virus affecting transmission and its ability to cause disease. Our analyzes suggest that there is a direct relationship between mortality caused by the virus and the efficiency in which it is translated," stated Dr Tello.
"The strain of the virus found in Chile would be one of the most efficient in the translation, which would be directly related to increased mortality," said the researcher, explaining one of the possible reasons for the high mortality reported in Mexico.
