A research team from Netherlands led by Ron Fouchier at Rotterdam’s Erasmus Medical Center said it had created a mutant version of the H5N1 bird flu virus that could for the first time be spread among mammals.
There are 3 types (A, B and C) of the influenza virus that can cause flu. Each has subtypical strain. H1N1 is a strain of the type A virus. H1N1 is what epidemiologists call a “triple reassortment” virus because it combines genes from different flu viruses, viral strains that normally affect pigs (swine flu), along with birds (avian flu) and human flu strains.
Brief exposure to UV light can cause mutations in the DNA of skin cells, including the host cells for melanoma. Sufficient of mutations can result to skin cancer.
