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.
