With 53 primary and secondary contacts of the 27-year-old woman testing negative to COVID-19 on the confirmatory RT-PCR test, Bhutan technically does not have a local transmission as of yesterday evening.

This, however, is the first COVID-19 positive case outside the secure boundaries of the quarantine facilities.

Prime Minister Dr Lotay Tshering said that a local transmission would happen only when the source of the infection cannot be traced. If a person tests positive without any recent travel history abroad or any contact with a positive case, then it would qualify as a local transmission, he added.

In the recent case, Lyonchhen said that the person came from a highly infectious country. “Moreover, she was IgG positive, meaning that she was exposed to the infection before.”
