The Russian president, Vladimir Putin, has been protected from the coronavirus by a special disinfection tunnel that anyone visiting his residence outside Moscow must pass through, according to state television.

The special tunnel, manufactured by a Russian company based in the town of Penza, has been installed at his official Novo-Ogaryovo residence outside Moscow where he receives visitors.

Demonstration footage of the tunnel showed masked people passing through it being sprayed with disinfectant from the ceiling and from the side.

The Russian news agency described the disinfectant as a fine cloud of liquid that covered people’s clothes and any exposed upper body flesh.
