The Chapter examines latest messages on 2011 influenza epidemics in Serbia that were found on 10 February 2011 on the websites of 24 Serbian Public Health Institutes. It adopts four of the STARCC criteria of the Center for Disease Control and Prevention: simplicity, timeliness, relevance and consistency. The variables used for the comparison of messages on influenza epidemics are: word count, the percentage of less known foreign words, last update and the percentage of words on preventive measures. Near half of the analyzed websites (11) had no information on influenza in previous 12 months. High variation coefficients of the investigated variables indicate a low consistency in internet based health communication within the network of Serbian public health institutions. Centralization and coordination in internet public health informing in Serbia is needed, as an effective preparatory measure for pandemics.
