The Global Forum for Health Research provides evidence, tools and discussion forums for decision-makers in research funding and policy to improve the health of the poor. Although it covers issues for both infectious and non-communicable diseases, the agency recognises that mental health problems are severely neglected in developing countries. As well as links to various publications and reports, the website also hosts RealHealthNews, which aims to share news on research and interventions that can improve the health of those in developing countries.

This information resource, published by the international public health agency Pan American Health Organization (PAHO), provides daily situation updates on the A(H1N1) influenza virus, or 'swine flu', including the number of confirmed cases reported in individual countries in the Americas and PAHO activities and recommendations.

The site publishes documents in English and Spanish that include background information on the virus as well as guidelines on laboratory procedures, surveillance, clinical management and infection control. It also links to videos of PAHO press conferences on influenza A(H1N1) and other online swine flu resources.

An independent global programme of scientific collaboration co-sponsored by the United Nations Children's Fund (UNICEF), the United Nations Development Programme (UNDP), the World Bank and the World Health Organization (WHO). Its goal is to help coordinate, support and influence global efforts to combat a portfolio of major diseases of the poor and disadvantaged, including malaria.

It funds research teams in developing countries to improve on and develop approaches to disease prevention, diagnosis, treatment and control. It also supports capacity-building and implementation of new methods. These activities are focused in Africa, South-East Asia and South America. The website provides useful information in clear, accessible language on research activities, as well as background information on disease and transmission. It contains animated graphics of parasites' lifecycle, and a searchable archive of over 13,000 images related to tropical diseases freely available for non-commercial purposes. Download pdf 

This part of the WHO's website focuses on the links between climate change and health. One factsheet looks specifically at climate change and infectious disease: it examines the historical evidence for links between climate and vector-borne disease, outlines different models to forecast climatic influences on infectious disease and offers examples of exactly how changes in climate can affect the spread of infectious disease. Another factsheet describes how to translate the science into useful policy decisions so will be particularly valuable for policymakers.

This website aggregates WHO publications on food safety and highlights relevant meetings and conferences. It includes links to the WHO initiative to estimate the global burden of foodborne diseases and links to the WHO's five keys to safer food that provides information and training material to improve food safety. Food safety, alongside nutrition and food security, is one of the WHO's strategic objectives for 2008–2013.

The WHO's site on influenza A(H1N1), or 'swine flu', provides daily updates and maps of the spread of the 2009 outbreak of swine flu and official WHO statements on the virus, as well as background documents and regional information.

It publishes guidance for different groups of people, including individuals, communities, national authorities and health professionals, and presents answers to frequently asked questions about the disease, vaccines, antiviral drugs, levels of pandemic alert and travel.
