Even the Congress has issued a statement saying she was a victim of viral fever.
This is the second time in the past three months that the Congress president has been admitted to a hospital.
Last week, Sonia along with her daughter Priyanka Vadra and children vacationed at Wildflower Hall, an Oberoi Group luxury resort, 15 km uphill from Shimla.
They also visited Charabra where Priyanka’s cottage is being constructed, an official there was quoted as saying.
“In the resort, they spent the entire day there,” as per media reports.
