The high transmissibility of SARS-CoV-2 before and shortly after the onset symptoms suggests that only diagnosing isolating symptomatic patients may not be sufficient to interrupt spread infection; therefore, public health measures such as personal distancing are also necessary. Additionally, it will important detect newly infected individuals who remain asymptomatic, which account for 50% or more cases. Molecular techniques “gold standard” diagnosis infection. However, massive use these has...
