NATURE SCIENTIFIC REPORT 20/03/17 A smartphone-based diagnostic platform for rapid detection of Zika, chikungunya, and dengue viruses. Assay speed and sensitivity We aimed to develop a rapid and reliable QUASR RT-LAMP assay for ZIKV, while relying on previously reported RT-LAMP assays for CHIKV and DENV17,19,22.
We first set about identifying an optimal primer set for ZIKV, using the LAMP-compatible SYTO intercalating dyes to perform real-time monitoring. We then adapted the optimal primer set to the target-specific QUASR endpoint detection technique. The mechanism and chemistry of QUASR-based RT-LAMP detection techniques has previously been described in detail22. At least one recent publication describes a different RT-LAMP assay for ZIKV utilizing leuco crystal violet indicator13. We prepared a ZIKV RNA standard from cultured ZIKV.

Today I have an awesome technology guest post on monitoring diseases via cell phones and Google maps from the beautiful Alysa Jeff.
Enjoy! You never know what diseases could be lurking. Most of us have come across or could come across rapid diagnostic tests such as pregnancy tests, blood glucose levels or strep throat tests. Dropping liquid or drops on a strip isn’t the hard part, but the hard part comes in reading out the results. Many times human errors lead to incorrect results, thus becoming a health risk. The researchers basically described it as a device known as the RDT-reader attachment that clips onto a cell phone. Being very efficient in its action, the attachment can read almost any type of diagnostic test available. The attachment’s work doesn’t end there; it goes on to transmit the results wirelessly to a server for processing, storage, and mapping via Google Maps to track the spread of certain conditions and diseases around the world over time.
SCIENTIFIC REPORTS 09/03/15 Using Mobile Phone Data to Predict the Spatial Spread of Cholera. GENOME MEDICINE 29/09/16 Mobile real-time surveillance of Zika virus in Brazil. Why are so few ZIKV genomes available more than a year after the virus was discovered in the Americas?
Data from the Zika Open Research Portal ( suggest that, in an animal model of infection, ZIKV viral load reaches a maximum only 1–2 days after virus infection. Furthermore, in humans, it seems that viral load peaks within a week of onset of clinical symptoms . The early peak in viremia, combined with mild symptoms for many ZIKV infections, means that there is often little virus left for sequencing when clinical samples (usually serum) are taken from patients with suspected ZIKV infection. Consequently, it has proven comparatively difficult to obtain full ZIKV genomes directly from clinical material without enrichment (for example, Most commonly this is undertaken by growth in cell culture, but this method is laborious and has the potential to introduce culture-specific genetic changes.
FRONTIERS IN PLANT SCIENCE 06/09/16 Using Deep Learning for Image-Based Plant Disease Detection 1EPFL, Switzerland 2Penn State University, USA. 1EPFL, Switzerland 2Penn State University, USA Crop diseases are a major threat to food security, but their rapid identification remains difficult in many parts of the world due to the lack of the necessary infrastructure.
The combination of increasing global smartphone penetration and recent advances in computer vision made possible by deep learning has paved the way for smartphone-assisted disease diagnosis. Using a public dataset of 54,306 images of diseased and healthy plant leaves collected under controlled conditions, we train a deep convolutional neural network to identify 14 crop species and 26 diseases (or absence thereof). The trained model achieves an accuracy of 99.35% on a held-out test set, demonstrating the feasibility of this approach. Overall, the approach of training deep learning models on increasingly large and publicly available image datasets presents a clear path towards smartphone-assisted crop disease diagnosis on a massive global scale. JOURNAL OF FISH DISEASE 15/08/16 A novel use of social media to evaluate the occurrence of skin lesions affecting wild dusky grouper, Epinephelus marginatus (Lowe, 1834), in Libyan coastal waters (concerne Facebook)
The social media network Facebook™ was used to gather information on the occurrence and geographical distribution of dusky grouper dermatitis, a skin lesion affecting the dusky grouper, Epinephelus marginatus.
Dusky grouper are common targets for spear fishermen in the Mediterranean and by monitoring spearfishing activity in Libyan waters, it was possible to document skin lesions from their entries on Facebook. Thirty-two Facebook accounts and 8 Facebook groups posting from 23 Libyan coastal cities provided a retrospective observational data set comprising a total of 382 images of dusky grouper caught by spearfishing between December 2011 and December 2015. Skin lesions were observable on 57/362 fish, for which images were of sufficient quality for analysis, giving a minimal prevalence for lesions of 15.75%. Only dusky grouper exceeding an estimated 40 cm total length exhibited lesions. PNAS - 2016 - Digital epidemiology reveals global childhood disease seasonality and the effects of immunization.

Award Abstract #1534126 PFI:BIC - Pathtracker: A smartphone-based system for mobile infectious disease detection and epidemiology This Partnerships for Innovation: Building Innovation Capacity (PFI:BIC) project will develop a mobile sensor technology for performing detection and identification of viral and bacterial pathogens.
By means of a smartphone-based detection instrument, the results are shared with a cloud-based data management service that will enable physicians to rapidly visualize the geographical and temporal spread of infectious disease. When deployed by a community of medical users (such as veterinarians or point-of-care clinicians), the PathTracker system will enable rapid determination and reporting of instances of infectious disease that can inform treatment and quarantine responses that are currently not possible with tests performed at central laboratory facilities.

Open Archive Abstract Outbreaks of infectious diseases at mass gatherings can strain the health system of the host region and pose a threat to local and global health.
In addition to strengthening existing surveillance systems, most host nations also use novel technologies to assess disease risk and augment traditional surveillance approaches. We review novel approaches to disease surveillance using the Internet, mobile phone applications, and wireless sensor networks. These novel approaches to disease surveillance can result in prompt detection. Keywords. JOURNAL OF MEDICAL INTERNET RESEARCH - 2014 - Detecting Disease Outbreaks in Mass Gatherings Using Internet Data. Introduction Background Historically, infectious diseases have devastated societies.
Examples include the “Black Death” bubonic plague of the 14th century in which between 30-40% of Europe’s population is estimated to have died , and the influenza epidemic of 1918-1920, in which as many as 50 million are estimated to have died . Despite very significant advances in medicine, infectious diseases remain potentially very serious threats to society.
For example, a pandemic influenza is rated as the greatest national risk on the UK government risk register .

Mobile phones improve case detection and management of malaria in rural Bangladesh. UNIVERSITY COLLEGE LONDON 09/05/13 Mobile health technologies to rapidly test and track infectious diseases. Early-warning sensor systems that can test and track serious infectious diseases – such as major flu epidemics, MRSA and HIV – using mobile phones and the internet are being developed by a major new Interdisciplinary Research Collaboration (IRC) led by UCL. The new £11 million IRC, funded by the Engineering and Physical Sciences Research Council (total investment £16 million), will develop mobile health technologies that allow doctors to diagnose and track diseases much earlier than ever before.
The IRC will pioneer low cost, easy to use mobile phone-connected diagnostic tests based on advances in nanotechnology for use in GP surgeries, pharmacies, elderly care homes, developing countries and at home. The mobile tests aim to identify diseases with high sensitivity and specificity and give results within minutes from just a pin-prick of blood or a simple swab. The UCL team are already developing a smart-phone-connected prototype test for HIV with industry partners OJ-Bio.

UNIVERSITY OF ILLINOIS - 2010 - Feasibility of Long-term Monitoring of Everyday Health Through Smartphones. EUREKALERT 12/03/12 Smartphones more accurate, faster, cheaper for disease surveillance. Smartphones are showing promise in disease surveillance in the developing world.
The Kenya Ministry of Health, along with researchers in Kenya for the Centers for Disease Control and Prevention, found that smartphone use was cheaper than traditional paper survey methods to gather disease information, after the initial set-up cost. Survey data collected with smartphones also in this study had fewer errors and were more quickly available for analyses than data collected on paper, according to a study presented today at the International Conference on Emerging Infectious Diseases in Atlanta.
Researchers compared survey data collection methods at four influenza surveillance sites in Kenya. At each site, surveillance officers identified patients with respiratory illness and administered a brief questionnaire that included demographic and clinical information. A total of 1,019 paper-based questionnaires were compared to 1,019 smartphone questionnaires collected at the same four sites.

NDTV 16/06/14 Brazilians Hope to Help Fight Dengue With New Smartphone App. While World Cup referees finally have goal-line technology to prevent mistakes, doctors in Brazil will soon have their own computer gizmo to contain dengue outbreaks. In the tropical northeastern city of Natal, a new smartphone application could allow residents to alert authorities about the location of concentrations of mosquitos and cases of dengue with the touch of a finger.
The app was developed by university researcher Ricardo Valentim in collaboration with epidemiologist Ion de Andrade, who works for the Natal city council. "If someone identifies dengue, they pinpoint it on the (application's) map and that allows us to see where it is developing and to react immediately to stop it spreading," Andrade said. The "Dengue Observatory" app is in beta mode for now but is expected to come online this month. Once up and running, it will allow authorities to know exactly where to act. "If it's mosquitos, we can locate and treat the water source. There is no cure for the mosquito-borne disease. BMC Med Inform Decis Mak. 2014 Dec 24;14(1):5.
