In total, 614 admin2 areas (2.4% of all admin2 areas considered, representing 125 million people) were classified as unsuitable for hookworm transmission, 713 (2.8%, 122 million people) for the transmission of ]) are carried out to ensure that available data data that complies with GAHI inclusion/exclusion criteria are included.For the current analysis, survey data were collated between 19, data older than this was used if no other data were available for a particular country.There is currently no calibration available for the whole human mt DNA genome, incorporating both coding and control regions.Furthermore, as several authors have pointed out recently, linear molecular clocks that incorporate selectable characters are in any case problematic.A total of 166 countries were classified as potentially endemic, including all countries in Asia (Central, east, south and south-east), Oceania, Latin America and the Caribbean, North Africa and the Middle East and sub-Saharan Africa.For each of these countries, digital boundaries obtained from 2009 version of the Administrative Level Boundaries project (SALB) [] to estimate populations at the second administrative level (admin2, typically termed a district) for 2000.Inevitably, these numbers will have changed during the last decade: on the one hand, prevalence may have declined in some part due to improvements in living conditions and expansion of major deworming efforts; on the other hand, population growth may have increased the numbers infected.

The primary aim is to update global estimates of infection prevalence, thus providing reliable national and sub-national descriptions of variation in infection risk, highlighting major changes in the global picture of STH between 19, and identifying countries and regions where data are still notably lacking.We here confirm a modest effect of purifying selection on the mt DNA coding region and propose an improved molecular clock for dating human mt DNA, based on a worldwide phylogeny of 2000 complete mt DNA genomes and calibrating against recent evidence for the divergence time of humans and chimpanzees.We focus on a time-dependent mutation rate based on the entire mt DNA genome and supported by a neutral clock based on synonymous mutations alone.Estimating the burden of different diseases requires (i) reliable estimates of prevalence of each disease and (ii) an analytic framework within which to estimate morbidity and mortality attributable to each disease.In the case of intestinal nematodes (or soil-transmitted helminths, STH) several efforts have been made to provide worldwide prevalence estimates since those first assembled by Norman Stoll in 1947 [].The abstracted dataset consisted of 6,651 quality-checked, geo-referenced estimates of infection prevalence.
