Recently, a cluster of epidemics occurred in Belgium's "Princess Elizabeth Polar Station" in Antarctica, and 16 of the 25 staff members were diagnosed with the new crown virus.
The Belgian side believes that the members of the Princess Elizabeth station have all been vaccinated against the new crown vaccine, and the infection is likely to be caused by the Omi Keron variant.
It is reported that the Chinese scientific expedition team has always followed strict epidemic prevention measures. Before that, it had been forbidden to go to sites in other countries to "drop in". The team members are currently all normal.
