The prevalence of symptoms that characterise an omicron infection differs from those of the delta SARS-CoV-2 variant, apparently with less involvement of the lower respiratory tract and reduced probability of hospital admission. Our data indicate a shorter period of illness and potentially of infectiousness which should impact work–health policies and public health advice.

The duration of current symptoms in dually vaccinated subjects averaged:
8.3 days for Omikron and
9.6 days for Delta.
Here, the differences were less pronounced.
The duration of acute symptoms in triple vaccinated persons was on average:
4.4 days for Omikron and
7.7 days for Delta.
Thus, the difference in symptom duration was particularly evident in the triple vaccinated. Triple vaccinated individuals thus overcome delta symptoms about two days faster than double vaccinated individuals. According to the study, symptoms of an omicron infection disappeared almost four days earlier after booster vaccination.
