DengueNet, built on the Global Health Atlas platform, is the World Health Organization's central data management system for the global epidemiological and virological surveillance of dengue fever (DF) and dengue haemorrhagic fever (DHF) created in partnership with WHO Regional and Country Offices, Ministries of Heath, WHO Collaborating Centres and laboratories. The network collects standardized data from all DengueNet partners worldwide, and provides ready access to a variety of indicators such as incidence, case fatality rates (CFR), frequency and distribution of DF and DHF cases, number of fatalities and circulating virus serotypes.
The key objective of DengueNet is to provide a standard platform for sharing current surveillance data in order to detect and monitor incidence and trends of dengue and DHF. This system promotes greater standardization of dengue reporting, making national data more comparable than they are today. DengueNet also provides unrestricted access to useful information that can help public health professionals with advance warning of epidemics to improve preparedness, case management, and reduce fatality rates.
"FluNet is a global web-based tool for influenza virological surveillance first launched in 1997. The virological data entered into FluNet, e.g. number of influenza viruses detected by subtype, are critical for tracking the movement of viruses globally and interpreting the epidemiological data. The data at country level are publically available and updated weekly. The results are presented in various formats including tables, maps and graphs."
