Speaking exclusively over the telephone from his hotel room on Monday late afternoon, the South Africa-born Luden said, "yes, I've tested positive. It was last Tuesday".
"But it is all good this side. There are no symptoms and I am being looked after very nicely by the medical staff".
Luden, who has worked with the Pakistan (2014-2019) and Bangladeshi (2008-2013) national teams in the past was hired by the Sri Lanka Cricket (SLC) board earlier this year.
A Degree holder in Sports and Exercise Technology, Luden has obtained his Level 3 Cricket Coaching certificate from Cricket South Africa, where he has also worked with the players in the past.
His main job at the High-Performance Center of the SLC is to look after the fitness of the national and elite players. His extensive experience is being used when injured players are referred to him.
