Temperature-Independent, Portable, and Rapid Field Detection of Ebola via a Silk-Derived Lateral-Flow System

googlesciencefair.com - 2015

I developed a “stable and stored at room temperature” Ebola Assay Card, applicable as an ELISA-based diagnostic for diseases such as HIV, Lyme and certain cancers, that will allow for water-activated, timed-release detection of Ebola antigens, with detection limits that are analogous to current sandwich ELISA techniques. Reagents become chemically “stabilized” when mixed into silk, which enables them to remain “chemically active” without refrigeration. This Ebola Assay Card will allow for shipment and storage without refrigeration, and provide detection of the Ebola viral antigens based on color change in as little as 30 minutes.

As West Africa’s Ebola outbreak winds down, an effort is under way to make the best use of the tens of thousands of patient samples collected by public-health agencies fighting the epidemic.  Samples from the Ebola epidemic in West Africa are held by public-health agencies in the region and abroad.

On 6–7 August, the World Health Organization (WHO) convened a meeting in Freetown, Sierra Leone, to discuss how to establish a biobank for up to 100,000 samples of blood, semen, urine and breast milk from confirmed and suspected Ebola patients, as well as swabs taken from the bodies of people who died from the virus. Held by health agencies in both West Africa and the West, the samples could be valuable in understanding how the current Ebola crisis evolved, preparing for future outbreaks and developing public-health research capacity in a region that depends on outside experts.

Telemedicine and innovative devices could help reduce unnecessary exposures to virus

Space technology such as satellite images and telemedicine could play a bigger role in helping to control the Ebola outbreak that's killed more than 11,250 people, a Canadian doctor says.

This week's issue of the medical journal Lancet Infectious Disease includes a commentary titled "Help from Above — outer space and the fight against Ebola."

The virulence of Ebola virus strains appears to be innately linked to the degree of disorder in proteins that form their nucleocapsids. Computational analysis has revealed that strains responsible for the most lethal outbreaks of Ebola show significantly higher levels of intrinsic protein disorder than less virulent strains, in a discovery that could constitute a major breakthrough in understanding the pathogen’s behaviour.

With over 27,000 confirmed, probable and suspected cases and more than 11,000 fatalities worldwide, the ongoing Ebola outbreak has resulted in considerably more casualties since late 2013 than all other outbreaks combined. There are no effective treatments or vaccines against the haemorrhagic fever that evinces Ebola infection; however, strains of the virus with drastically different virulence have emerged since the first outbreak in 1976, with fatality rates ranging from 25 to 90%.
