About This Project

Zika (PORTUGUESE) is a rapidly emerging pandemic, a global health emergency. ZIKV has been associated with central nervous system malformations in babies alongside neurological and immune complications in adults. There is a shortage of labs offering ZIKV testing in Brazil and worldwide. We are developing a new diagnostic assay that identifies the presence of ZIKV and other viruses. The goal is an easy, rapid, economical, local & reliable test without the need of a lab or highly trained personnel

What is the context of this research?

The current situation in Brazil and Latin America urgently requires an easy to use robust, affordable diagnostic test for the detection of Zika virus. Current estimation for number of infections are over 1.5 million and rapidly rising.

There is a correlation between Zika virus infection, microcephaly(abnormal smallness of the head associated with incomplete brain development) and Guillain-Barre syndrome a rapid-onset muscle weakness, where the immune system damages the peripheral nervous system. However current diagnostic status is underdeveloped as the gold standard is a RT-PCR test that is unavailable in most clinics due to cost, shortage of trained personnel and equipment. The urgent need for new diagnostics that are scalable, accurate and accessible was described on WHO SRF (Feb 2016).

What is the significance of this project?

Currently diagnosis can only be confirmed by slow, expensive and relatively rare laboratory testing for the presence of the ZIKV genome in the blood or other body fluids, such as urine or saliva. There is a problem of cross reactivity with other viruses in some lab tests, making it hard to identify Zika vs Dengue.

Patients with other viral infections including Dengue and Chikungunya are proposed to increase the likelihood of microcephaly and neurological complications. We have designed our assay to be able to differentiate and test for all of these viruses simultaneously. This makes our tool perfect for helping doctors and epidemiologists better understand, disentangle and identify the true cause of ZIKV's freightening complications.

What are the goals of the project?

We have already started to rapidly develop, optimize and verify a specific and sensitive ZIKV test based on isothermal genomic RNA amplification (Wang et al.) from minimally treated samples (heated), without the need for a lab, complex equipment, or highly trained personnel. It will be able to distinguish between closely related viruses, in less than 60 minutes from sample extraction, and results easily seen.

We will first validate and optimize our primer set, using purified Zika genomes, also checking other co-circulating viruses, human and mosquito DNA. We will then test on ZIKV grown in the lab. Finally we will test on real samples of humans and mosquitoes, which we have access to at the LIKA lab in Brazil.

Once we validate >300 samples we will release the kit on an open website

We have already done the in-silico(computational) work, analyzing over 40 recently sequenced ZIKV variants from the Americas, and have designed multiple isothermal primer sets for different unique regions of the ZIKV genome, taking into account recent mutations, relatedness to other viruses and the human genome. We are ready to order and try them out, just need your help!

In order to optimize our assay and make sure it can work even in low income settings we need to use multiple primer sets in many parallel experiments in different conditions, concentrations of virus and enzymes, pHs, temperatures, durations, using different visualization techniques and samples.

Reagents cost and availability are a rate limiting step for us, this funding will allow us to move faster.

We have a list of supplies needed in order to create and validate the diagnostic: specific short strands of DNA (primers), plastic micro-tubes\plates, heating element, gloves, plastic pipettes, enzymes, dyes, and buffers.

This project proposes to develop and validate a rapid, accurate field test for Zika infection, the first of its kind. The researchers running this campaign are well positioned to make a major impact on the clinical diagnosis of Zika virus infection, especially because the areas that have been the hardest hit are the least equipped to diagnose infection. The field test this group would design could be a turning point for similar areas impacted by the Zika outbreak.
This project aims at an essential and challenging goal: fast and cost-effective method to diagnose Zika virus infections in the field, without using laboratory equipment. As a synthetic biologist, I find this an elegant, simple and realistic solution a complicated problem. I highly recommend it. This can save many lives.
This project is addressing a topic critical for Brazil and other countries health system. Actions like that, trying to ease and speedup the disease detection, are crucial at this moment. The people involved are serious and combine the skills necessary to make a successful project.
This is a truly GREAT effort by a fantastic TEAM, aiming at an important, extremely RELEVANT GLOBAL public health PROBLEM of dire consequences for us all, specially the young ones and their families. It is a great honour to be both an endorser and supporter of this project. Silvio M., @srlm
This project has a powerful aim: to improve the point-of-care based in new approaches for diagnostics. As an expert in digital disease detection, for us it's very important to have platforms like that, helping to fight against epidemics, like Zika virus. Epitrack is completely favorable and we are glad to see this initiative as a scientific innovation applied to public health.
As a member of LIKA's research team , I find of great importance the development of this project . The Zika virus diagnostic will help in many ways to understand and prevent neurological and vascular complications. The relevance of the project and the skills of the researchers involved are fully endorsed by me.
I think this is an exciting and socially very needed project.
Knowing the researchers in person makes me very excited about this project, as I truly believe that this project has the ability to significantly aid in the combat against Zika in a timely fashion. I wish you all the best.
The ongoing outbreak of the Zika virus in Brazil and its alarming association with infant abnormalities, calls for better diagnostics and treatments for Zika. This project is of importance and timely, and the team of proffesionals lrading it are capable to meet the goal set by them. I gladly endorse them and wish them best of success.
This project is pretty amazing in showing how a group of people can come together in a short period of time to help deal with a serious issue.
I am happy to endorse this project as I believe it will be of great importance to shed light into this major public health problem.
The importance of this project needs no introduction. Right now, Zika is arguably the largest viral threat on the planet, and we know almost nothing about it. This team is proposing to develop a cheap, fast and high throughput method to identify Zika virus from patient samples – a critically important step for our understanding and eventual control of Zika. I have known Gilad for a number of years. His drive and motivation for innovative science and entrepreneurship is inspiring. I give this project my highest support.
I fully endorse and support this project. The team behind this project is doing an amazing job acting in loco on the ZIKA pandemic epicenter. Besides that, the concept of create a #lowcost #opensource diagnosis kit to be used by people in poor and rural areas is really breakthrough. As an investor in Synthetic Biology and Singularity University alumni (EP & GSP), projects like this increase my faith in humanity, and the power we have when we act together using exponential technologies to solve the greatest humanity problems.
This project addresses a real and urgent need in Zika-infected regions and beyond. Underlying the project is a potentially winning blend between state-of-the -art technology and it's wide open-source application that ensures its availability where it matters most.
