Abstract excerpt

This study used the nucleotide sequence coding for the HA1 domain of virus haemagglutinin to show that influenza A/Finland/158/91, which represents the H1N1 subtype viruses prevalent in Finland in 1990/91, was a direct descendant of a virus (A/NN/1605/88) isolated during the 1988/89 epidemic season in Japan. The elevated rate of 7.4 x 10(-3) nucleotide substitutions per site per year is discussed. The new branch...
