CDC to analyze swine flu virus behind girl’s dying in Brazil
The Facilities for Illness Management and Prevention plans to probe samples collected from a deadly influenza an infection in Brazil, the World Well being Group introduced, after investigators found the dying was brought on by an H1N1 variant spreading in pigs.
Occasional so-called “spillovers” of H1N1 swine flu have been noticed all through the world in individuals who interacted with contaminated pigs.
