ABSTRACT
PCR tests are known to give the most accurate results, but are not suitable for mass testing. This article suggests the use of data extraction to diagnose Covid-19. For this purpose, data from rapid antigen tests, external signs of infection and general blood count are processed. The result is that the reliability of antigen tests increases from 50% to over 72%. The future development of the system is to generate a hypothesis about the likelihood of complex application of Covid-19. PCR tests are known to give the most accurate results, but are not suitable for mass testing. © 2022 IEEE.
ABSTRACT
Coronavirus infections are common in both animals and humans. This article presented an overview of the scientific literature on SARS-CoV-2 infection. Various aspects of this infection have been considered: a common characteristic and part of the international experience. Improving knowledge on COVID-19 is an important step in dealing with this infection.
ABSTRACT
Introduction: Coronavirus infection COVID-19 is a new pandemic disease worldwide. It is mainly a respiratory infection, manifested by fever, muscle aches, sore throat, shortness of breath, cough and in more severe cases - pneumonia, respiratory failure and death. It has recently been found that COVID-19 can affect the gastrointestinal tract, cause heart damage, blood clotting disorders or impact the nervous system. The review aims to summarize data from the literature and own observations of neurological complications in COVID-19. Material and Methods. Based on keywords, scientific publications on various Internet platforms related to COVID-19 with neurological manifestations have been selected. The most common clinical symptoms and syndromes found in the world practice are summarized. Own experience in persons with COVID-19 treated at the Military Medical Academy - Sofia is analyzed. Results. Neurological manifestations in patients with COVID-19 include various symptoms and syndromes of the central nervous system, peripheral nervous system and skeletal muscles. Most commonly, patients with COVID-19 have headache and/or dizziness, loss of smell or taste, and general muscle weakness. Rarely, the disease is associated with Guillain-Barre syndrome, stroke, meningitis or encephalitis, cerebral and/or focal neurological symptoms, and other manifestations. The recently established European Neuro-Covid Registry (ENERGY) of the European Academy of Neurology aims to establish the real incidence of neurological manifestations of the disease. Conclusion: A review of the literature confirms that COVID-19 damages the nervous system, which may be asymptomatic or clinically manifested by a variety of cerebral and focal neurological symptoms and syndromes, the frequency of which is yet to be determined.
