Virological data reported to FluNet by GISN NICs from countries in the northern and southern hemispheres (week 17-40). Bars represent the
number of specimens reported positive for influenza viruses during the reporting week represented in the X-axis. The X-axis also shows the
number of countries that reported to FluNet during the respective week. Example: 17 (45) means that in week 17, 45 countries reported. The right
side Y-axis shows the proportion (%) and the left Y-axis shows the absolute number of specimens reported positive for influenza viruses
(influenza A subtypes, pandemic H1N1 and influenza B).
