Ganguly is double vaccinated and has been traveling extensively, taking part in all professional activities.
The 49-year-old was rushed to a hospital late on Monday night as a precautionary measure after his RT-PCR test returned positive.
"He was taken to Woodlands Nursing Home last night. He has been given medication and is currently stable," a BCCI source, who is keeping track of Ganguly's health, told PTI.
Ganguly was admitted to hospital twice earlier this year and underwent emergency angioplasty after having some cardiac issues.
His elder brother Snehasish Ganguly had also tested positive for COVID early this year.
