Influenza activity patterns of co-circulating influenza A subtypes (pH1N1 and H3N2) and influenza B in MENA, 2009–2017. a Heat map showing the levels of influenza activity of each type/subtype in each region (n = 3) from April 2009 to December 2017 period. The color scale denotes the percentage of influenza positive samples relative to corresponding color shade. Annual activity trends of influenza viruses: pH1N1 (red), H3N2 (blue) and influenza B in Gulf (b), Levant (c) and North Africa (d) regions since April 2009 to December 2017. Bars represent the total number of samples collected in each year while doted pattern in each bar denotes number of influenza positive samples in each specific year
