Background description includes information that may be useful in understanding the present invention. It is not an admission that any of the information provided herein is prior art or relevant to the presently claimed invention, or that any publication specifically or implicitly referenced is prior art.
The pandemic diseases have a massive impact on human lives, health and quality of life. Such diseases are challenging healthcare systems and economies worldwide.
Some of the well-known pandemic diseases are Ebola, SARS, COVID-19, etc. The testing of patients infected by pandemic disease is very difficult task. Presently, the detection of virus includes pathogen isolation and identification, serological methods, molecular biology methods. Etiological method is the most traditional detection method. Specificity of the etiological method is strong. Also, the results of the etiological method are true and reliable, but the method has some limitations such as for example, it requires considerable time, requires considerable number of staff engagement and has low sensitivity etc.
In some of the diseases, many infected individuals show no symptoms. Therefore, successful epidemiological surveillance strategies are required to monitor the spread of such diseases in the individuals. Further, the outbreak of new strains should include large-scale screening methods that enable periodic and continuous testing of the general population.
However, testing capacity has been limited, hampering attempts to control the spread of disease. Some of the diseases require reliable nasopharyngeal sampling. The RT-PCR testing is highly invasive and requires both specialized staff and appropriate conditions for the manipulation and transport of the samples to comply with clinical standards and protocols expected by regulatory authorities. Lateral flow device antigen tests are cheaper and accurate when detecting individuals with high infection, however, correct testing requires nasopharyngeal sampling. Therefore, regular large-scale testing is difficult because accurate tests are either too invasive, expensive, or logistically complicated to implement, which make them unviable for the task.
There are certain testing methods that have been disclosed in the public domain to overcome the problems from the above-mentioned methods. Configuration of such testing method requires equipment. The size of the equipment, cost effectiveness of the different components of equipment, additional components required by the equipment are some of the challenges faced by the medical institutions or healthcare professionals. Not only this, some equipments are developed using expensive technologies which are incorporated therein and are not effective and have shorter life span costing a lot towards maintenance of such equipments.
Following are some of the attempts made to develop a cost-effective instant disease testing method.
