An introduction to leaflet maps in R

Presented September 19, 2017. 

The main goal of this talk is to demonstrate map making in R using leaflet. We will cover trivial and non-trivial examples. I use the data.table package as my default data container and for all data manipulation.

An Integrated Mosquito Surveillance Module in New York State

There were several stand-alone vector surveillance applications being used by the New York State Department of Health (NYSDOH) to support the reporting of mosquito, bird, and mammal surveillance and infection information implemented in early 2000s in response to West Nile virus. In subsequent years, the Electronic Clinical Laboratory Reporting System (ECLRS) and the Communicable Disease Electronic Surveillance System (CDESS) were developed and integrated to be used for surveillance and investigations of human infectious diseases and management of outbreaks.

Kidenga: Public engagement for detection and prevention of Aedes -borne viral diseases

Zika, chikungunya, and dengue have surged in the Americas over the past several years and pose serious health threats in regions of the U.S. where Ae. aegypti and Ae. albopictus mosquito vectors occur. Ae. aegypti have been detected up to 6 months of the year or longer in parts of Arizona, Florida, and Texas where mosquito surveillance is regularly conducted. However, many areas in the U.S. lack basic data on vector presence or absence.

Enhanced Aedes spp. surveillance across jurisdictions in Arizona’s border region

As part of a statewide effort to enhance surveillance for Aedes spp.mosquitoes the Office of Border Health (OBH) took the lead inproviding technical assistance on surveillance in counties bordering Mexico. In 2016, OBH sought ways to enhance surveillance in a wider geographic area. Trap locations closer to the border were established as a priority, given high amount of traffic across the international line, high border Aedesmosquito activity, and native cases of dengue reported at the border in Mexico.

A Syndrome Definition Validation Approach for Zika Virus

In 2016, the World Health Organization declared Zika virus a global public health emergency. Zika infection during pregnancy can cause microcephaly and other fetal brain defects. To facilitate clinicians’ ability to detect Zika, various syndrome definitions have been developed. 


To develop and validate a Zika virus disease syndrome definition within the GUARDIAN (Geographic Utilization of Artificial Intelligence in Real-Time for Disease Identification and Alert Notification) surveillance system.

Flea-Borne Rickettsiae in Almaty Oblast, Kazakhstan

Flea-borne diseases in Kazakhstan have been a significant health risk to inhabitants and visitors for ages, particularly plague. Flea-borne rickettsial disease threats are unknown in Kazakhstan, we therefore initiated a study to detect and identify flea-borne rickettsiae among fleas collected in the Almaty Oblast, in southeastern Kazakhstan.

Using Syndromic Surveillance to Enhance Arboviral Surveillance in Arizona

Arizona is facing multiple public health threats from arboviral diseases. State and local public health departments are monitoring two mosquito-borne outbreaks within its borders and two in adjacent territories. To prevent transmission, viremic patients must be identified in a timely manner and encouraged to avoid additional mosquito exposure and vector control actions must be implemented. Using traditional surveillance, however, health departments may not be alerted until the laboratory confirms and reports a positive result, which may take up to 14 days after specimen collection.
