An Overview of Signs and Symptoms to Determine Coronavirus and Omicron Patients in Primary Care and Hospitals

Coronaviruses, a type of virus family, cause severe respiratory diseases in people. The coronavirus is most frequently linked to the common cold, but in persons with SARS (severe acute respiratory syndrome) virus infection, it can also lead to serious respiratory sickness. The spread of the coronavirus is by having direct contact with infected saliva, mucus, or blood. Infected surfaces, such as those in hospitals or other healthcare facilities, can potentially spread the infection when touched. Now spreading globally is the Omicron version of the severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2). According to preliminary studies, the Omicron variant of SARS-CoV-2 has a higher probability of re-infection. To recognize COVID-19 as well as omicron people in hospitals and primary health care, this review study focuses on the symptoms and indications. The data was collected and analyzed from more than one hundred high-impact original research papers to conclude their results and make a comparison between methods and findings.
