Study presence of COVID-19 (SARS-CoV-2) in the sweat of patients infected with Covid-19.

Severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) disease, which started in Wuhan, Chin, has now become a public health challenge in most countries around the world. Proper preventive measures are necessary to prevent the spread of the virus to help control the pandemic. Because, SARS-CoV-2 is new, its transmission route has not been fully understood. In this study, we aimed to investigate the presence of SARS-CoV-2 in the sweat secretion of COVID-19 patients. Sweat specimens of 25 COVID- 19 patients were collected and tested for SARS-CoV-2 RNA by Real-time Polymerase Chain Reaction (RT-PCR) method. After RNA extraction and cDNA amplification, all samples were examined for the presence of ORF-1ab and N genes related to COVID-19. Results annotated by Realtime PCR machines software based on Dynamic algorithm. The results of this study showed the absence of SARS-CoV-2 in the sweat samples taken from the foreheads of infected people. Therefore, it can be concluded that the sweat of patients with COVID- 19 cannot transmit SARS-CoV-2. However they can be easily contaminated with other body liquids.

Alteration of Liver Biomarkers in Patients with SARS-CoV-2 (COVID-19).

INTRODUCTION: Coronavirus disease 2019 (COVID-19) emerged in China and spread worldwide. In this study, we assessed the characteristics of markers of the liver in patients with COVID-19 to provide new insights in improving clinical treatment. PATIENTS AND METHODS: We recruited 279 patients who confirmed COVID-19 and the data of liver biomarkers and complete blood count of patients were defined as the day onset when the patients admitted to the hospital. RESULTS: The average of LDH value was 621.29 U/L in all patients with COVID-19, and CPK was 286.90 U/L. The average AST was 44.03 U/L in all patients, and ALT was 31.14 U/L. The AST/ALT ratio was 1.64 in all patients. The measurement of CRP was increased by 79.93% in all patients. Average ALT and AST values of patients with elevated ALT were significantly increased in comparison to patients with normal ALT (P-value = 0.001), while AST/ALT ratio was significantly decreased compared to patients with normal ALT (P-value= 0.014). In addition, the average LDH of patients with elevated ALT was significantly increased compared to patients with normal ALT (P-value = 0.014). CONCLUSION: Hepatic injury and abnormal liver enzymes related to COVID-19 infection is an acute non-specific inflammation alteration.
