England are playing two Tests against Sri Lanka in Galle. Despite strict efforts to enforce a bio-secure bubble, they have already seen all-rounder Moeen Ali test positive since arriving in the South Asian nation.

The England cricket board said they were not worried about the infections.

"Our protocols have been excellent and we continue to be vigilant," spokesman Danny Reuben told AFP.

He said players respected social distancing, wore masks in indoor settings at the hotel and where possible dined outdoors.

Reuben said Moeen was still isolating at a different hotel in Galle and would return to the team as soon as it was safe.

England arrived in Sri Lanka on January 3 and spent a week in isolation in the southern town of Hambantota before travelling to Galle.
