Abstract :
Since the emergence of the new Omicron
B.1.1.529 variant of Severe Acute Respiratory Syndrome
Coronavirus 2 (SARS-CoV-2) in November 2021, the
number of positive cases has continued to increase. Due to
its rapid spread, this new variant has become dominant
worldwide. This is also the case in Morocco, where 95%
of SARS-CoV-2 infections are secondary to this variant.
In addition, the high number of mutations in the viral S
protein has raised concerns about the possibility of escape
of the virus from antibodies induced by previous infection
or by vaccination. However, very few studies have
reported the notion of reinfection with this new variant.
We report four cases of Covid-19 reinfection with the
Omicron variant, diagnosed at the Ibn Rochd University
Hospital in Casablanca, in four vaccinated healthcare
professionals.
