Russian authorities have dug a trench around a remote Siberian village to enforce a quarantine, after dozens of residents contracted the coronavirus, which local officials believe was spread at a traditional shaman ritual, Reuters reported.

The village of Shuluta, located some 30 kilometres south east of Lake Baikal in Siberia's Buryatia region, has 37 confirmed cases of the virus among its 390 residents.

At least 95 other people are believed to have been in contact with those infected and are also required to quarantine, said the head of the local administration, Ivan Alkheyev.
