The Reds will be without their star forward for the next three games after a second positive test for the disease this week.
With reports of Salah flying back to England on a special plan from Egypt international duty, there have been concerns about how Liverpool will cope against the Foxes.
But the Reds boss has given a positive update on the 28-year-old and his his return to the squad.
Speaking in the pre-match press conference, Klopp said: “He is probably back today. In close contact and how it always is.
“He's in a good place, feels well. No symptoms. Nothing to say in public about [the wedding].”
Klopp went on detail his own experience of managing Covid-19 difficulties with social occasions.
The manager added: “What I can say, I was in Germany in the summer and a friend moved a birthday party [for me] and I decided not to go.
“It was allowed. In other countries there's more social pressure and a bros wedding is a special moment. My players are incredibly disciplined.”
They will miss the Egyptian in the European campaign, with the forward grabbing a goal and an assist in Italy earlier this month.
While the forward has played a big part in all six league wins, scoring five goals and making three assists for his side.
A bigger concern for Klopp against Leicester will be his lack of defenders, missing Virgil van Dijk and Joe Gomez due to injury.
