The new type of corona virus causes great concern all over the world due to its global spread. The general problems with this new virus are: diagnosis, mode of transmission, long incubation period (3 to 14 days), negativities in accurately estimating the number of infected cases in the community and easy spread environments that cause pandemics (shopping malls, public transportation vehicles, education, health institutions, family, living spaces, etc.) is insufficient protection. In addition to the PCR test, patients can be diagnosed by performing thorax tomography in the diagnosis of covid 19 in studies conducted. Since false negativity and positivity in PCR tests and findings in thorax tomography can be confused with different lung diseases, no specificity and sensitivity ratio for diagnosis has been specified [9,10,11,12].

The transmission of this disease to healthcare workers and its easy spread in the community complicates the disease [9,10]. At the same time, since there is no definite treatment and vaccine for this viral disease, which can spread so easily, the situation causes an even more serious picture for people with suppressed immune system, elderly patients and people with chronic diseases [10,11]. In our study, elderly and patients with chronic diseases were hospitalized in intensive care units. Death occurred in patients who developed multiple organ failure in patients hospitalized in intensive care.

The patient groups identified as 19 are the groups that constitute the most frequent indication for hospitalization. In addition, pregnancy and old age are other risky conditions that should be followed meticulously [12]. In studies conducted on this disease, fever is seen in 85.81% of the clinic and it is measured as 38 degrees. It is stated that 53.88% of the patients have a fewer below 38 degrees. Dry cough which is the second most common symptom, was detected in 67.10% of the patients. Diarrhea and vomiting were detected in 12.47% of the patients [13,14,15].

We did not have a patient hospitalized with complaints of severe diarrhea and vomiting. In studies increased international normalized ratio (INR) was found in 32.04% of patients with leukocytopenia, 16.77% with lymphocytopenia, 1.08% with thrombocytopenia and 14.84%, and decreased albumin levels in 36.56% [14,15]. While increased ALT level was observed in 10.11% of the patients, increased AST level was detected in 11.18% of the patients. Again, the amount of creatine kinase was increased by 4.95% and lactate dehydrogenase levels were determined to be increased by 25.16%. In over 50% patients, increased erythrocyte sedimentation rates and C Reactive Protein (CRP) were detected [13]. In our study, leukocytosis was found in 67% of our patients, lymphopenia in 37%, increase in AST level was 12.4%, ALT level increased by 21.32%, lactate dehydrogenase level increased by 26.3% and CRP level increased by 59.2%. seems compatible. While lung involvement is detected at a rate of 30-60% in the literature on chest radiographs, this appearance is seen as peripherally located, irregular limited non-homogeneous opacity increases in the middle and lower zones of the lung. Even if there is no involvement in the lung radiograph, Covid 19 infection cannot be excluded [14,15]. The diagnosis of Covid 19 disease can be made by Thorax Tomography in patients with positive PCR test. While bilateral involvement is detected at a rate of 98% in the thorax tomography of the patients, ground glass opacities and subsegmental consolidation are observed in the patients who do not need intensive care, while multilobar and subsegmental thoracic tomography of the patients hospitalized in the intensive care unit is observed. consolidation areas are observed. Again, although pleural effusion and focal pleural thickening are rare, they can be seen in patients with advanced Covid 19 lung disease [16]. At the same time, thoracic CT Angio should be performed in patients prone to thrombosis [17]. In our study, 181 (88.29%) patients had ground glass opacities and subsegmental consolidation areas, whereas 24 (11.70%) patients had multilobar and subsegmental consolidation areas on thorax tomography. In imaging studies, pneumonia was detected in 88.31% of patients, and ground-glass appearance and consolidation areas were observed in thorax tomography [13]. Corticosteroids, which have anti-inflammatory and immunosuppressive effects as an immune modulator treatment method in the treatment of SARS-CoV, provide early resolution of fever. Ribavirin, a nucleoside analogue used in the treatment, is the most commonly applied agent with antiviral activity against many DNA and RNA viruses. Ribavirin blocks the viral replicase polyprotein, thereby stopping RNA replication. Another method used in the treatment of SARS-CoV is protease inhibitor [18]. Lopinavir-ritonavir joint formulation, which is also used in the treatment of HIV infection, can be used together with ribavirin in the early stages of the disease to help antiviral treatment (18). favipiravir; It is a drug effective against many RNA viruses and is a ribonucleic acid (RNA) polymerase inhibitor that blocks viral replication. In in vitro studies, high doses of Favipiravir have been recommended in Covid 19 infection, using it in the treatment of SARS-CoV2. The side effects of favipiravir are flatulence, nausea, vomiting, hyperuricemia, abnormal liver function tests and chest pain [20]. In our study, all our patients were treated with favipiravir. Corticosteroids are potent anti-inflammatory and antifibrotic drugs that downregulate proinflammatory cytokine transcription, preventing a prolonged cytokine response, accelerating the resolution of systemic inflammation and regression of pulmonary symptoms in pneumonia. It has been shown to reduce mortality by 12.1% in COVID-19 patients connected to mechanical ventilation in intensive care units and by 2.9% in patients treated with oxygen support [21]. However, in addition to the use of interferon and general steroids in the treatment of immune-mediated lung injuries, additional research is needed to develop new treatment methods such as additional antiviral therapies, anti-monoclonal antibodies, anti-viral peptides and vaccines [22]. It was also stated that there is a consensus on the use of antibiotics [23].

In our study, cortisteroid treatment was started in 27 patients with severe lung involvement and clinical symptoms on tomography. While the symptoms of 3 of our patients regressed and were treated in the ward, 24 of our patients were admitted to the intensive care unit considering the need for mechanical ventilators. 13 of 205 patients had mortality. In conclusion, Covid 19 is a disease that needs to be treated in a multidisciplinary way. It is important that patient groups with comorbidities that increase morbidity and mortality are hospitalized and followed closely. We believe that early diagnosis and initiation of the treatment process will reduce morbidity and mortality.
