The 38-year-old "Kahaani" actress was detected with dengue last week and has been advised bed rest by her doctor for the next 10-15 days.
"Good morning all. Thank you for the genuine concern, wishes, prayers, love and jokes. I've been resting at home and am recovering well," Vidya posted on Twitter.
The actress will be seen next in "Kahaani 2" which releases in November.
Vidya has wrapped the shoot of "Begum Jaan" and will begin work on her Malayalam film which is a biopic on poetess Kamla Das.
