    Neurological complications and infection mechanism of SARS-CoV-2

    Introduction

    The emergence of Corona Virus Disease (COVID) in December was as a result of the outbreak of a novel human coronaviral pathogen, which was termed severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2). This virus has a high similarity with severe acute respiratory syndrome coronavirus (SARS-CoV). The virus, SARS-CoV-2, belongs to a beta genus of coronaviruses and is the seventh member of human coronaviruses,1,2 sharing ~80% sequence similarity to SARS-CoV.3,4 Furthermore, the homology of SARS-CoV-2 is over 90% similar to those of coronaviruses from bats and pangolins, demonstrating its powerful ability to transmit cross-species.5 The virus shares a similar spherical structure to other coronaviruses (CoVs) with a diameter of ~ nm and is a single-stranded positive-sense RNA virus,6,7 composed of four proteins: membrane (M) glycoprotein, nucleocapsid (N) protein, spike (S) glycoprotein, and envelope (E) glycoprotein.8 The N protein conjugates with genomic RNA to form nucleocapsid, while S, M, and E proteins combine to create an envelope to enclose the nucleocapsid.6 It was revealed t

      COVID and the Nervous System

      In , a new coronavirus called ‘SARS-CoV-2’ quickly spread worldwide. Infection by this virus causes the disease known as COVID COVID primarily targets the respiratory system, but it also affects the nervous system and other organs. Most cases of COVID are mild, especially in those who have been vaccinated, and go away within a couple of weeks. However, severe cases of COVID can damage a person’s organs. When COVID affects the lungs, it prevents the body from getting enough oxygen, which can lead to disability or death.

      Some people have symptoms of COVID that last for weeks, months, or even years after their initial infection. Some may develop new symptoms after an initial recovery or after mild initial COVID These prolonged symptoms are known as “Long COVID,” which can affect many parts of the body, particularly the brain and nervous system. Medical and research communities are studying how COVID might cause or contribute to the neurological symptoms of Long COVID. Researchers hope to better understand this connection to support diagnosis and develop effective treatments for people experiencing Long COVID.
