Dengue is a vector-borne disease that causes a substantial public health burden within its expanding range. In this review, we compare the main approaches that have been used to model the future global distribution of dengue and propose a set of minimum criteria for future projections that, by analogy, are applicable to other vector-borne diseases.

Ebola is a zoonotic filovirus that has the potential to cause outbreaks of variable magnitude in human populations. This database collates our existing knowledge of all known human outbreaks of Ebola for the first time by extracting details of their suspected zoonotic origin and subsequent human-to-human spread from a range of published and non-published sources. In total, 22 unique Ebola outbreaks were identified, composed of 117 unique geographic transmission clusters.

Ebola virus disease (EVD) is a complex zoonosis that is highly virulent in humans. We assembled location data on all recorded zoonotic transmission to humans and Ebola virus infection in bats and primates (1976–2014). Using species distribution models, these occurrence data were paired with environmental covariates to predict a zoonotic transmission niche covering 22 countries across Central and West Africa.

The leishmaniases are vector-borne diseases that have a broad global distribution throughout much of the Americas, Africa, and Asia. A global assessment of the consensus of evidence for leishmaniasis was performed at a sub-national level by aggregating information from a variety of sources. These high-resolution evidence-based maps can help direct future surveillance activities, identify areas to target for disease control and inform future burden estimation efforts.

Since the first isolation of dengue virus (DENV) in 1943, four types have been identified. Documenting the type-specific record of DENV spread has important implications for understanding patterns in dengue hyperendemicity and disease severity as well as vaccine design and deployment strategies. Here we summarize the global distribution of confirmed instances of each DENV type from 1943 to 2013 in a series of global maps.

Dengue is a systemic viral infection transmitted between humans by Aedes mosquitoes. Here we undertake an exhaustive assembly of known records of dengue occurrence worldwide, and use a formal modeling framework to map the global distribution of dengue risk. We then pair the resulting risk map with detailed longitudinal information from dengue cohort studies and population surfaces to infer the public health burden of dengue in 2010.

It is perhaps surprising to state that we have an extremely poor knowledge of the global distribution of the vast majority of infectious diseases. Here we argue that this information gulf has serious implications for global public health surveillance and that too little attention is given to spatial epidemiology in international preparedness planning.

The primary aim of this review was to evaluate the state of knowledge of the geographical distribution of all infectious diseases of clinical significance to humans.
