The actress returned to filming last month after being on maternity leave. She gave birth to a baby boy named Freddie at the beginning of August.
Writing on Twitter today (November 13), Anderson revealed that Alicia's return scenes will air in the middle of December.
She told fans: "I am STILL ill!! Go away cold.
"For those asking, Alicia will be back on screen mid dec....minus the cold hopefully!! Let's see what David's been up to."
Alicia's temporary exit storyline saw her jailed for slapping Val Pollard. To make matters worse, she was heartbroken after realising that David had no romantic feelings for her following their sham wedding.
In Alicia's absence, David has been dating Priya Sharma (Fiona Wade) - and actor Matthew Wolfenden, who plays the shopkeeper, has predicted that a catfight could be on the cards in the love triangle plot.
