In December 2019, a new coronavirus emerged and caused an acute respiratory disease now known as coronavirus disease 2019 (COVID-19). The virus was identified to be a beta-coronavirus related to severe acute respiratory syndrome coronavirus (SARS-CoV) and thus was named SARS-CoV-2. Currently, the patients infected by the novel coronavirus are the main source of infection; asymptomatic infected people can also be an infectious source. Based on the current epidemiological investigation, the latent period is 1 to 14 days, mostly 3 to 7 days. The main manifestations include fever, fatigue and dry cough. Nasal congestion, runny nose, sore throat, myalgia and diarrhea are found in a few cases.
SARS-CoV-2 rapid test kits can offer the SARS-CoV-2 antigen and antibody tests to support the professional and layusers use, which are helpful for early screening of COVID-19.
