The potential for transmission of communicable diseases is influenced by a complex interplay of
host, agent and environment. Accurately defining risk requires a careful consideration of the
potential interactions of all three factors, in this case within the specific context of the area and
population affected by the emergency.

Tropical diseases encompass all diseases that occur solely, or principally, in the tropics. In practice, the term is often taken to refer to infectious diseases that thrive in hot, humid conditions, such as malaria, leishmaniasis, schistosomiasis, onchocerciasis, lymphatic filariasis, Chagas disease, African trypanosomiasis, and dengue.

World Bank group works to improve the living conditions for those in need. They work extensively with Tropical diseases and provide information about their projects on their website.

Neglected Tropical Diseases (NTDs) are a group of parasitic and bacterial diseases that cause substantial illness. NTDs are the source of tremendous suffering because of their disfiguring, debilitating, and sometimes deadly impact. They are referred to as "neglected" because they have been largely wiped out in the more developed parts of the world but persist in the poorest, most marginalized or isolated communities of the world.

The Human Development Report 2016 ’Human Development for Everyone’ looks into these two questions. It recognizes that in every society certain groups are far more likely to suffer disadvantages than others and identifies deep-rooted, and often unmeasured, barriers to development.

In the World Development Indicators database (and most other time series datasets), all 189 World Bank member countries, plus 28 other economies with populations of more than 30,000, are classified so that data users can aggregate, group, and compare statistical data of interest. Groupings are primarily based on income and on the regions used for administrative purposes by the World Bank.

Infectious diseases of poverty (IDoP) disproportionately affect the poorest population in the world and contribute to a cycle of poverty as a result of decreased productivity ensuing from long-term illness, disability, and social stigma. In 2010, the global deaths from HIV/AIDS have increased to 1.5 million and malaria mortality rose to 1.17 million. Mortality from neglected tropical diseases rose to 152,000, while tuberculosis killed 1.2 million people that same year. Substantial regional variations exist in the distribution of these diseases as they are primarily concentrated in rural areas of Sub-Saharan Africa, Asia, and Latin America, with geographic overlap and high levels of co-infection. Evidence-based interventions exist to prevent and control these diseases, however, the coverage still remains low with an emerging challenge of antimicrobial resistance. Therefore, community-based delivery platforms are increasingly being advocated to ensure sustainability and combat co-infections.
