3 DISCUSSION
Severe illness of COVID-19 begins after 7 days (approx.) of onset of symptoms. The most common symptoms of COVID-19 are fever, cough, tiredness, dyspnea, and diarrhea. (10, 11). Severe COVID-19 dyspnea triggers progressive development of respiratory failure, followed by severe hypoxemia. In fact, lymphopenia is normal to the majority of severe COVID-19(12, 13). The analysis of COVID-19 is made using real-time polymerase chain reaction methods, partial or complete viral genome sequencing, and plasma antibody level measurements. Early diagnosis of SARS CoV-2 is made by collecting, processing, and analyzing respiratory samples such as nasopharyngeal aspirate, combined (nasal and oral) swab samples, sputum, tracheal lavage fluid, or bronchoalveolar lavage fluid(14). SARS CoV-2 RNA is isolated from respiratory samples and measured utilizing rRT-PCR using the process of placing probes. COVID-19 is verified by viral RNA being found in the samples obtained(15). Within a week of the emergence of COVID-19 symtomps, plasma IgM and IgG tests are necessary to allow the infection to be easily detected. It showed that a patient had the safe amount of IgG within 14 days. Through the point-of-care test, it can identify the existence of serum antibodies within 15 minutes and can determine the level of the infection(16). CT findings are significant both for diagnosis and follow-up. To present, there has been no proof of successful treament for COVID-19. Antiviral medications and respiratory treatment are the primary medication used to cure the disorder. In addition, while several therapies have been suggested, quarantine is the only method that seems to be successful.
