Latest sporadic outbreaks triggered by new imported source, determined as Delta variant: health official - Global Times

After tracing the sources and conducting other epidemiological investigations, 106 of them were found to be related to tourist activities involving a total of 13 tour groups or self-driving tours. .

At present, the epidemic is at the stage of rapid development as the cases of infections that are not related to tour groups have been increasing

Authorities demand more groups including staff working at ports, border inspection, quarantine locations and those who attend major activities or plan to go overseas for study or work, as well as groups above 60 years old who have higher risks of being infected, to be included into the groups for enhanced immunity, according to the official.
