*One reference sequence was used for each comparison. For a genotype with >1 reference sequence, the indicated sequence was used for comparison. †Range of percentage nucleotide differences between all Uganda sequences and the reference sequences for the nucleoprotein gene. ‡Since we had only 2 Ugandan hemagglutinin gene sequences, the lowest percentage difference is shown. However, both percentages did not vary by >0.1%.
