Anez becomes the second South American president in a matter of days to contract the coronavirus after Brazil's Jair Bolsonaro announced his positive result on Tuesday.
Earlier, Anez had declared herself interim president of Bolivia after the armed forces pressured elected head of state Evo Morales into resigning sent a bill to Congress calling for elections in 2020.
Bolivia was incensed by what it called an attempt by Spanish embassy staff to infiltrate the Mexican mission in La Paz last Friday to extract Quintana, who has been Morales' right-hand man since his early days in power.
During a press briefing on Wednesday, Jeanine Anez said that the aim of her proposed legislation is to ensure a "transparent" electoral process leading to a result which is "respected".
Justiniano further said, "Unfortunately, no progress has been made with the MAS bloc".
The violence came as Bolivia’s interim president, Jeanine Áñez, said Morales would face possible legal charges for election fraud if he returned home, even as the ousted leader contended he is still president, despite resigning after massive protests against him.
The President has been ousted and there need be no quibbling over semantics.
"I speak of a change of regime of reversing the conditions that turned us into a totalitarian country, to build fully democratic values, institutions and procedures," she further added.
It was unclear if the move would quell unrest in the highland capital, La Paz, and other cities unleashed by Morales' disputed bid for a fourth term.
