Introduction: Coronaviruses are a large family of viruses and subordinate viruses that range from the common cold virus to more serious diseases such as SARS, Morse, and Covid 19. Their structure also has a typical Aranian genome. The structure of this virus consists of two layers; The nucleus of the virus is made up of genetic material and the outer layer is made up of protein crowns. After entering the host cell, the virus particle is uncovered and its genome enters the cell's cytoplasm. Coronavirus is a new type of infectious disease caused by the recently discovered coronavirus. How is coronavirus diagnosed? 1 polymerase chain reaction (shows if you now have corona) 2 antibody tests or serological tests (shows if you have had coronavirus in the past) Polymerase chain reaction In the first half of January, Chinese researchers identified the genetic formula for the coronavirus and made it available to all. For this, a suspected person with a sore throat or nose will be sampled and sent to a laboratory Samples are usually taken from people who have a fever, shortness of breath, and a cough. To diagnose this method, quantitatively, an enzyme called reverse transcriptase is used, which makes it possible to determine the number of viruses from the number of genomes in the tested sample in addition to detecting the virus. The reverse transcriptase enzyme is obtained using part of a single-stranded virus genome, followed by a double-stranded version of the supplement, or DNA, and then the genetic content is multiplied using a chain reaction, followed by fluorescence. And a method called the amount and type of genetic material of the virus is determined at the moment. Coronavirus testing is done in 3 steps To diagnose coronavirus, the test is first performed to identify it, and then the result is confirmed by another test, if both tests are positive; The third test determines the type of coronavirus. In the field of coronavirus detection, by performing the necessary tests, it is determined between 24 and 72 hours whether the person is infected with this virus or not. Anti-wind test: Some blood will be taken from you and the following two chemicals will be checked in your blood: IgM antibodies, which are formed early in the infection. IgG antibodies, which appear later in the body after recovery. It takes about 4 weeks for IgM antibodies to form in the human body Antibodies can show the prevalence of covid 19. Researchers are studying how to extract plasma from patients with improved antibodies and use it to treat patients with covid 19. Coronavirus prevention: There is currently no specific vaccine for Corona 2019. Avoid close contact with sick people Avoid touching your eyes, nose or mouth Stay home when you are sick Clean and disinfect objects and surfaces you are dealing with. Wash your hands with soap and water several times a day for at least 20 seconds. Drugs that affect coronavirus: Drugs that affect viruses in a way that stops the growth and activity of the coronavirus inside the body. Drugs that can calm the immune system. Nowadays, people with the coronavirus become worse when their immune system reacts too much and damages the main organs of the body. Antibodies obtained from the blood of infected patients or made in a laboratory capable of attacking the virus
Methods: by review other article
Results: The best way to prevent this disease is to wash your hands and reduce contact with other people
Conclusion: So far no cure has been found for this virus, so the treatment of this virus includes care and prevention. For this purpose, if you have this virus, you should rest and use acetaminophen and ibuprofen to reduce pain and fever.
