This international HIV/AIDS charity dedicates a section of its website to traditional medicine, and with good reason — traditional medicines are especially popular with people who have HIV. The website provides advice for those seeking traditional remedies for HIV, lists potential therapies and highlights the role of traditional healers in combating HIV in Africa. It advocates that traditional healers are well placed to encourage HIV prevention, and convince people to get tested for HIV if they are at risk.

The Gates Foundation's nutrition programme aims to include essential vitamins and minerals in the diets of people in the developing world, and to guarantee proper nutrition under the age of two, including in the womb.

Progress sheets and a strategy overview on the organisation's nutrition program are available to download as well as press releases and information on grants given. The website also includes job listings, downloadable fact sheets, financial statements and annual reviews.

The foundation funds population-wide food fortification programmes and invests in research and development of diagnostic tools and biomarkers for identifying and measuring micronutrient deficiencies. It also funds research to examine how different nutritional interventions affect infection.

The health gateway of the Climate Institute, which aims to help policymakers tackle climate change, has detailed notes on the resurgence of infectious diseases through global warming. These include vector-borne diseases spread through mosquitoes, ticks, triatomine bugs, sandflies and blackflies. It also looks at rodent-borne diseases, which are also set to increase as the climate changes — increased heavy rainfall can drive rodents out of their burrows and climate change is set to alter human migration patterns which could bring people into closer contact with rodents.

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 partnership of government and non-government organisations, researchers, international bodies and the private sector has a much-called for goal: to increase cooperation between organisations involved different sectors such as health, climate, humanitarian assistance, ecosystems, research and operational services.

The partners collaborate on regional projects to increase capacity within the medical and environmental science communities; use rural communication networks to provide information to remote communities; and enhance the capacity of public-health services to predict and respond quickly to cholera, malaria, meningitis and other climate-sensitive diseases.
