of the Invention
COVID-19 or the Novel Coronavirus 2019 disease is a pandemic that began to spread in December 2019 through the contraction of a virus known as the Severe Acute Respiratory Syndrome Coronavirus or SARS-CoV-2. First discovered at a seafood market in Wuhan, China, SARS-CoV-2 rapidly proliferated to other countries, until infected patients were found in almost every country worldwide. A study of the genetic materials of SARS-CoV-2 allowed researchers to establish that its nucleotides closely resembled those of a virus found in bats from China. Thus, it was hypothesized that SARS-CoV-2 had originated from a virus found in bats and mutated into strains, which could be spread from animals to humans, eventually leading to human-to-human transmission. Accordingly, COVID- 19 can be contracted by exposure to fine airborne droplets released by the respiratory system of patients. This exposure can arise from coughing or sneezing in the direction of other people and contact with the secretions of infected persons. Such secretions include saliva, nasal discharge, and phlegm. Contact with SARS-CoV-2 is also possible on the surfaces of various objects and appliances, as well as in the air via exposure through the eyes, nose and mouth. Moreover, SARS-CoV-2 can persist on a wide variety of surfaces for a period of 2 hours to as long as 9 days. Nevertheless, it has been determined that SARS-CoV-2 is rapidly destroyed when exposed to UV radiation from sunlight. In contrast, SARS-CoV-2 can also remain on surfaces or in the air for extensive periods at room temperature and below, especially in areas with low relative humidity. When the human body is exposed to a disease or foreign contaminants, its immune system will create a type of protein known as antibodies, produced from white blood cells termed as B cells. These antibodies are produced around 7-10 days after the body’s exposure to disease or foreign contaminants. However, if the disease causes severe and abrupt symptoms, the body will be incapable of producing antibodies in time. In this instance, antibodies specific to the disease (known as “therapeutic antibodies”) can be administered to the patient immediately, in order to directly combat the infection. The immunity acquired from such an approach has been termed as “instant immunity”.
COVID-19 is a disease that causes severe irregularities in the respiratory system. Commonly encountered symptoms of COVID-19 include fever, dry cough, drowsiness, nasal congestion, conjunctivitis, sore throat, headache, myalgia, skin rash, nausea, vomiting, diarrhea, shivering, and the loss of taste and smell. In some cases, severe symptoms such as hyperventilation and chest pain can be encountered. Complications such as respiratory system failure, acute respiratory illness, blood infection, thrombosis and damage to the heart, liver or kidneys may also arise.
