Projects under development

In collaboration with external partners, the Project Tycho® team continues to improve and expand the online data system. We will ensure that all new components will be fully tested and reviewed before public release. New features or updates that are in an advanced stage of development are listed below. Most of these features can be accessed by invitation only at this point, but some are already open to the public.

Dengue data from 8 countries in Southeast Asia

Dengue surveillance data are routinely collected by public health agencies around the world, but due to a variety of barriers, these data cannot always be used for scientific analysis. We collaborated with colleagues in over 18 institutions across 8 countries in Southeast Asia to integrate dengue surveillance data and to detect patterns of disease transmission at a regional level. We found that dengue epidemics occur synchronously across this region and that large epidemics are driven by high temperatures that can be caused by a strong El Niño season. This study and detailed methodology on data collection, integration, and analysis, have been published in the Proceedings of the National Academy of Sciences (PNAS). All our country partners have agreed to provide public access to this unique dataset so that other investigators can benefit from our work.

Chikungunya data

Since late 2013, cases of Chikungunya have been reported in the Americas, starting in the Caribbean. In 2014, this epidemic has spread throughout the region through importations and autochthonous transmission between countries. The Project Tycho® team has transformed weekly reports of Chikungunya cases and deaths provided by the Pan American Health Organization (PAHO) and the French Agence régionale de santé (ARS) into a digitized data resource for science and policy making.

Dengue WHO data

Valuable dengue surveillance data is provided online by the World Health Organization in various locations. The WHO headquarters integrated dengue data for most countries into a centralized database, DengueNet, and WHO regional offices in Latin America (PAHO), Southeast Asia (SEARO) and the Western Pacific (WPRO) also provide dengue surveillance reports for member countries. We integrated dengue data from these various sources and will provide open access to these data fully integrated into the Project Tycho® online data system. This project is currently in an advanced stage of testing and is accessible to invited reviewers only.

Dengue data for Brazil World Cup cities

Recently, investigators from the University of Pittsburgh, Carnegie Mellon University, and the Brazil Ministry of Health used historical dengue surveillance data to estimate the risk of dengue for tourists and football teams during the FIFA 2014 World Cup. The reported number of dengue cases by week for 2001 to 2014 week 21 used in this study was provided by the Brazil Ministry of Health. These data are consistent with monthly reports provided by the SINAN online system. To advance the transparency and reproducibility of this study, the full dataset is provided here. In the near future, these data will be integrated into the Project Tycho® data retrieval system.

Cambodia dengue data rescue

In partnership with the Cambodia Dengue Control Program, Project Tycho® is digitizing high resolution dengue surveillance data from district and provincial health offices in two pilot provinces of Battambang and Kampong Cham. Dengue surveillance data have been collected by health officers at district and provincial level for many years but not all details of these reports have been forwarded to the National level which has caused loss of epidemiological detail that could be relevant for decision making. To prevent the loss of valuable observational public health data and to advance the use of these data for science and policy, Project Tycho® is supporting this data rescue operation. This project is currently in an operational phase and can be accessed by project participants only.

Brazil dengue collaboration

In partnership with the Brazil National Dengue Control Program, Project Tycho® is reviewing dengue surveillance data for epidemiological studies including data reporting practices and prediction of dengue patterns. The Brazil Dengue Program routinely collects high quality information on dengue across all municipalities in Brazil. Project Tycho® supports the processing and analysis of these data for improved dengue control strategies. This project is currently in an operational phase and can be accessed by project participants only.
