Clinical Manifestations and Diagnostic Methods of Covid-19

The high prevalence of Covid-19, which has been spreading from Wuhan, China since late December 2019, has led to a sharp rise in global mortality, so that we are witnessing a global viral pneumonia, which has led to a major health problem in the world. Therefore, in order to control the prevalence of this disease, it is necessary to early prevention of virus infection through proper and timely diagnosis of this disease, especially in certain patients and asymptomatic patients and also to prevent its recurrence.

 In this study, according to the results of research published in ISI, Wiley, Science direct, PubMed, Scopus, etc. from January to July 2020, diagnostic methods based on the structural features (Serological techniques including ELISA kits) and clinical manifestations (Lung CT scan) of covid-19 have been used for accurate and timely diagnosis of this disease.

Due to its 2 to 14-day incubation period, the similarity of its symptoms to the common cold, and its high transmission capacity among different people, Covid 19 has become very prevalent around the world and it is currently considered a major health problem. Therefore, using appropriate and efficient diagnostic methods is one of the most important options for controlling this disease. The results of published research show that the covid 19 diagnostic kits and methods, which are based on serological, molecular and CT scan techniques, are among the most common diagnostic methods in the world. However, in some cases, these methods have false positive and negative results. Among them, false results from CT scans have been reported less than other methods.

It is recommended to diagnose this disease correctly and in a timely manner especially in asymptomatic people, diagnostic testing should be performed using several diagnostic methods and different patient samples.
