"Just as we expanded Google Flu Trends to much of Europe last fall in advance of the winter flu season, we're bringing Google Flu Trends to eight additional countries in the southern hemisphere where winter is approaching. We now show national estimates (and a few regions too!) of flu activity for Argentina, Bolivia, Brazil, Chile, Paraguay, Peru, South Africa, and Uruguay, bringing our grand total of countries with Google Flu Trends estimates to 28. South Africa is the first country we're adding in Africa, and we hope Google Flu Trends will provide useful information for football fans and foes alike," noted Google.
This video visualizes flu activity over the last two years in North America and Europe:
