The trends of influenza infection in Suriname were assessed from February 2010 through February 2011. Testing of 393 patients with symptoms of acute respiratory infection (ARI) revealed 15·3% Influenza B and 18·6% could be identified as influenza A positive, consisting of 56% influenza A(H1N1)pdm09 and 44% seasonal A(H3N2). Influenza infection occurred throughout the year, and all three influenza types affected young children as the primary population. The annual incidence of A(H1N1)pdm09 was 6·88 per 100 000 inhabitants [CI] 4·87–9·45. The spread of influenza could neither be linked to tourist flow from the Netherlands nor to contact rates related to school schedules.
