Shortly after the WHOs first notice a suspected case of omicron SARS-CoV-2 was reported in Liberec, Czech Republic. The primary goal of the following actions was to test the presence of the variant and stop the spread of the virus variant. On November 25 a sixty-year-old lady, who had recently returned from Namibia, visited a GP with flu-like symptoms and a rash on her chest. The antigen test was positive for SARS-CoV-2, a PCR test was planned. At that time, it was not known that a new variant of concern was spreading from Africa. On November 26 in the morning the GP announced a suspected omicron case to the Regional public health authority, who organized the following steps. A mobile sampling team was sent to the patient's home immediately, sample transported into the regional hospital and analyzed with the help of the national reference laboratory. The captured virus SARS-CoV-2 fitted the description of the omicron variant, was shared in the GISAID database and named hCoV-19/Czech Republic/KNL_2021-110119140/2021. Contact tracing was started immediately, eleven persons were tested and quarantined. One of them positive with no further spread. It is the first documented omicron case in the Czech Republic and one of the first cases in Europe, with an excellent systemic response to the alert.
