Clinical manifestation, diagnosis, prevention and control of SARS-CoV-2 (COVID-19) during the outbreak period

Abstract

The novel coronavirus SARS-CoV-2 (Covid-19), spreading from Wuhan, China, is one of the causes of respiratory infections that can spread to other people through respiratory particles, and can cause symptoms such as fever, dry cough, shortness of breath, anorexia, fatigue and sore throat in infected patients. This review summarizes current strategies on the diagnosis. Additionally, treatments, infection prevention and control of the SARS-CoV-2 are addressed. In addition to the respiratory system, this virus can infect the digestive system, the urinary system and the haematological system, which causes to observe the virus in the stool, urine and blood samples in addition to throat sample. The SARS-CoV-2 causes changes in blood cells and factors and makes lung abnormalities in patients, which can be detected by serological, molecular, and radiological techniques by detecting these changes and injuries. Radiological and serological methods are the most preferred among the other methods and the radiological method is the most preferred one which can diagnose the infection quickly and accurately with fewer false-negatives, that can be effective in protecting the patient's life by initiating treatment and preventing the transmission of infection to other people.
