Any acute or chronic infection requiring systemic antibiotic treatment or antiviral therapy within the last 7 days.
They have experienced fever (i.e., axillary temperature ≥ 38°C) within the last 3 days
Simultaneous participation in another clinical study.
Any condition, which, in the opinion of the investigator, might prevent the subject from participation or interfere with the evaluation of the study objectives.
