Health experts across the globe agree, that the information gained from testing, is crucial in the management of the epidemiological curve, curbing the spread of the infection, reducing mortality, and optimal use and implementation of medical resources and staff.</div><div class = "text-block">It is imperative to identify individuals with current infections, testing both symptomatic and asymptomatic individuals, to stop the human to human transmission, of the virus. To date, no country in the world has had the luxury of implementing blanket testing. Mainly because of the steep inclination of the epidemiological curve, whereby governmental and healthcare systems, cannot keep up with the rapid spread of the virus resulting in the exponential increase in symptomatic individuals requiring hospitalization and intensive care. Further challenges include logistical issues, in the distribution of testing kits to existing laboratories, setting up new facilities for sampling and testing, as demand increases. Lastly, third world countries have the added constraints of under-resourced healthcare systems and financial limitations to purchase enough molecular testing equipment.</div><div class = "text-block">Even if blanket testing were possible, diagnosing the SARS-COV-2 infected individual accurately remains a challenge.</div><div class = "text-block">This challenge exists for the following reasons: properties unique to the SARS-COV-2 virus (incubation period, a large portion of asymptomatic infected individuals spreading virus), the sensitivity of the RT-PCR ASSAY laboratory tests (depend on which combination of target genes are included in the various test kits, viral load present at the time of sampling, and availability of kits).</div><div class = "text-block">A positive RT-PCR ASSAY test confirms the presence of SARS-CoV-2 viral nucleic acids (RNA), in a nasopharyngeal swab, oropharyngeal swab, or any bodily fluid or tissue. Generally the sensitivity (accuracy) of RT-PCR ASSAY for SARS-COV-2 is in the region of 80%, with high specificity. Therefore individuals with symptoms of SARS-COV-2 who test negative (up to 20%), should not be managed on the test result alone, but also taking into account epidemiological risk factors (travel history, contacts), clinical symptoms, and by retesting the patient using a different sampling site.</div><div class = "text-block">Demonstrating seroconversion, the presence in serum of either IgM or both IgM and IgG or IgG, for SARS-COV-2, indicates a past (albeit recent past) exposure, viremia, and production of antibodies. Whether these antibodies are neutralizing and confer immunity is still being established. This type of test cannot be used to identify active infection.</div><div class = "text-block">Due to costs and the massive logistical demands on RT-PCR ASSAY producing companies (collection kits, purification units, extraction units, reagent solution production), RT-PCR ASSAY is only used in a certain portion of the population at this stage.</div><div class = "text-block"><span>NICD guidelines for RT-PCR ASSAY testing published on their website </span><a href="https://www.nicd.ac.za/wp-content/uploads/2020/04/COVID-19-Quick-reference-v12-09.04.2020_final-1.pdf" style = "text-decoration:underline;color:blue;cursor:pointer;"><span style = ":;:UNDERLINE;">https://www.nicd.ac.za/wp-content/uploads/2020/04/COVID-19-Quick-reference-v12-09.04.2020_final-1.pdf</span></a><span style = ":;:UNDERLINE;">:</span></div><div class = "text-block">Criteria for the person under investigation (PUI), i.e. a person to be tested for COVID-19 Persons with acute respiratory illness with sudden onset of at least one of the following: cough, sore throat, shortness of breath or fever [≥ 38°C (measured) or history of fever (subjective)] irrespective of admission status.</div><div class = "text-block">There is an international upsurge and call for emergency research protocols being submitted and approved for clinical trials of new drugs, vaccine development studies and other technology to combat the spread and loss of life caused by this pandemic. </div><div class = "text-block"><span style = "font-weight:bold;:UNDERLINE;">EPD is Novel technology for pathogen diagnosis</span></div><div class = "text-block">EPD scanning technology, is a completely novel technique, designed to assess the human body for the presence or absence of a pathogen.</div><div class = "text-block">The technology implements a unique scanning method, by delivering an extremely low electrical current to the skin, and then recording the resulting </div><div class = "text-block">physiological response to this stimulation, from the skin.</div><div class = "text-block">Although the technique is unique, there are similarities to existing technologies that can be used to explain the modus operandi, of this </div><div class = "text-block">novel technology. </div><div class = "text-block">The microcurrent delivery component of the diagnostic technology can be loosely described as containing elements analogous to </div><div class = "text-block">Microcurrent Electrical Therapy (MET) and TENS (Trans dermal electrical nervous stimulation), whereas the response component of </div><div class = "text-block">the technology can be seen as similar to Electrocardiography (ECG), Elelctro-enchephalogram (EEG) the Electrodermal Response (EDR), </div><div class = "text-block">and Body Impedance Assessment (BIA).All of these modalities are widely used, considered safe and have been extensively researched.</div><div class = "text-block">The skin offers convenient access to study the nervous system, not only is it richly innervated, but it also originates from the same embryonic layer </div><div class = "text-block">as the nervous system. </div><div class = "text-block">It is well known that the immune system and immune response is regulated by the neurological system.</div><div class = "text-block">EPD technology uses this physiological platform offered by the skin to access real-time information of the immune response and compares this </div><div class = "text-block">physiological information to electronically generated pathogen molecular patterns via a proprietary algorythm.</div><div class = "text-block"><span style = "font-weight:bold;:UNDERLINE;">Background:</span></div><div class = "text-block"><span style = "font-weight:bold;:UNDERLINE;">Immune system</span></div><div class = "text-block">The immune system consists of cells and proteins found in the blood, lymphatic system and tissue.
