Nine villages in Tak Bai district, where the first cases of the South African variant of Covid-19 were detected on Saturday, remained closed.
Nine villages were under
lockdown
after health authorities found the South African
variant
in three people, who recovered from the infections.
The South African
variant
is more
contagious
and could be more
resistant
to vaccines, it was reported on Saturday.
The
strain
was imported into Thailand by a Malaysian woman who illegally crossed the border to Thailand with her son and mother-in-law to visit her husband in Tak Bai from April 12-May 4.
Aside from the 32-year-old husband, details remained
sketchy
about the other three people infected with the B.1.351
strain
. The man's wife had already returned to Malaysia.
The first person found infected with the South African
variant
was a Thai
national
who returned from Tanzania in February. The cases in Tak Bai were believed to be first local
transmission
of the
strain
.
