treatment. In addition, correct classification will allow identification of
SARS-CoV-2 infected individuals with different risks thereby identifying demand
for treatment, care and support for each individual, improving treatment
effectiveness, and saving resources of medical sector and society. Thus, the
development of criteria for classifying risks and guidelines for initial
response are vital in this stage.
