Brucellosis, a zoonotic disease, was made statutorily notifiable in China 1955. We analyzed the incidence and spatial-temporal distribution of human brucellosis during 1955-2014 using surveillance data: aggregated data for 1955-2003 individual case 2004-2014. A total 513,034 cases were recorded, which 99.3% reported northern 1955-2014, 69.1% (258, 462/374, 141) occurred February-July 1990-2014. Incidence remained high 1955-1978 (interquartile range 0.42-1.0 cases/100,000 residents), then...
Dengue has been a notifiable disease in China since 1 September 1989. Cases have reported each year during the past 25 years of dramatic socio-economic changes China, and reached historical high 2014. This study describes changing epidemiology dengue this period, to identify high-risk areas seasons inform prevention control activities. We describe incidence distribution mainland using surveillance data from 1990-2014, which includes classification imported indigenous cases 2005-2014. From...
As successful malaria control programmes re-orientate towards elimination, the identification of transmission foci, targeting attack measures to high-risk areas and management importation risk become high priorities. When resources are limited is varying seasonally, approaches that can rapidly prioritize for surveillance be valuable, most appropriate measure a particular location likely differ depending on whether it exports or imports infections. Here, using example Namibia, method...
Abstract According to UN forecasts, global population will increase over 8 billion by 2025, with much of this anticipated growth expected in urban areas. In China, the scale urbanization has, and continues be, unprecedented terms magnitude rate change. Since late 1970s, percentage Chinese living areas increased from ~18% 50%. To quantify these patterns spatially we use time-invariant or temporally-explicit data, including census data for 1990, 2000, 2010 an ensemble prediction model....
BackgroundChanges in the geographical distribution of genetic disorders are often thought to happen slowly, especially when compared with infectious diseases. Whereas mutations, drift, and natural selection take place over many generations, epidemics can spread through large populations within a few days or weeks. Nevertheless, population movements interfere these processes, studies have been done their effect on disorders. We aimed investigate global migration sickle-cell gene—the most...

Abstract Many different methods are used to disaggregate census data and predict population densities construct finer scale, gridded sets. These often involve a range of high resolution geospatial covariate datasets on aspects such as urban areas, infrastructure, land cover topography; covariates, however, not directly indicative the presence people. Here we tested potential geo‐located tweets from social media application, Twitter, in production maps. The density 1x1 km grid cells over...
Capturing human movement patterns across political borders is difficult and this difficulty highlights the need to investigate alternative data streams. With advent of smart phones ability attach accurate coordinates Twitter messages, users leave a geographic digital footprint their when posting tweets. In study we analyzed 10 months geo-located tweets for Kenya were able capture people at different temporal (daily periodic) spatial (local, national international) scales. We also both long...
The quantification of parasite movements can provide valuable information for control strategy planning across all transmission intensities. Mobile carrying individuals instigate in receptive areas, spread drug resistant strains and reduce the effectiveness strategies. identification mobile demographic groups, their routes travel how these connect differing zones, potentially enables limited resources interventions to be efficiently targeted over space, time populations. National population...
The global flow of air travel passengers varies over time and space, but analyses these dynamics their integration into applications in the fields economics, epidemiology migration, for example, have been constrained by a lack data, given that passenger data are often difficult expensive to obtain. Here, modeled at monthly scale provide an open-access spatio-temporally resolved source research purposes (www.vbd-air.com/data). By refining annual-scale model Huang et al. (2013), we developed...
Social media platforms are increasingly seen as a source of data on wide range health issues. Twitter is particular interest for public surveillance because its nature. However, the very nature social such may act barrier to surveillance, people be reluctant publicly disclose information about their health. This concern in context diseases that associated with certain degree stigma, HIV/AIDS.The objective study assess whether adverse effects HIV drug treatment and sentiments can determined...
Recent developments in sensors, GPS and smart phones have provided us with a large amount of mobility data. At the same time, large-scale crowd-generated social media data, such as geo-tagged tweets, provide rich semantic information about locations events. Combining data surrounding enables to semantically understand why person travels location at particular time (e.g., attending local event or visiting point interest). Previous research on mining has been mainly focused patterns using only...
Air travel has expanded at an unprecedented rate and continues to do so. Its effects have been seen on malaria in rates of imported cases, local outbreaks non-endemic areas the global spread drug resistance. With elimination eradication back agenda, changing levels compositions malaria-free countries, threat artemisinin resistance spreading from Southeast Asia, there is a need better understand how modern flow air passengers connects each Plasmodium falciparum- vivax-endemic region rest...
Over the past century, size and complexity of air travel network has increased dramatically. Nowadays, there are 29.6 million scheduled flights per year around 2.7 billion passengers transported annually. The rapid expansion increasingly connects regions endemic vector-borne disease with rest world, resulting in challenges to health systems worldwide terms pathogen importation vector invasion events. Here we describe development a user-friendly Web-based GIS tool: Vector-Borne Disease...
Identifying human and malaria parasite movements is important for control planning across all transmission intensities. Imported infections can reintroduce into areas previously free of infection, maintain 'hotspots' import drug resistant strains, challenging national programmes at a variety temporal spatial scales. Recent analyses based on mobile phone usage data have provided valuable insights population likely within countries, but these are restricted to sub-national analyses, leaving...
The expanding global air network provides rapid and wide-reaching connections accelerating both domestic international travel. To understand human movement patterns on the their socioeconomic, environmental epidemiological implications, information passenger flow is required. However, comprehensive data remain difficult expensive to obtain, prompting researchers rely scheduled flight seat capacity or simple models of flow. This study describes construction an open-access modeled matrix for...
Due to worldwide increased human mobility, air-transportation data and mathematical models have been widely used measure risks of global dispersal pathogens. However, the seasonal interannual pathogens importation onward transmission from endemic countries rarely quantified validated. We constructed a modelling framework, integrating air travel, epidemiological, demographical, entomological meteorological data, probability dengue introduction countries. This framework has applied...
