Doctors at the All India Institute of Medical Sciences (AIIMS) has said that the two-year-old girl, Falak, is critical with meningitis and brain fluid function. She still remains on ventilator.

Doctors will decide Wednesday on a new set of antibiotic treatment which will depend on the reaction of the antibiotics given to her till now.

With the infection in her brain, the chances of her survival have dipped considerably.

Investigation reports of the fluid that had been taken out of her brain through surgery yesterday [Monday] have shown presence of infection. That is why her condition is still critical, M.C. Misra, head of the Jai Prakash Narayan Apex Trauma Centre at the AIIMS, said Tuesday.

She has contracted meningitis. We are administering all antibiotic cover to fight the infection. If she responds well, we will immediately conduct another surgery of the brain and extract the remaining infectious fluid, he added.

There has not been any significant improvement in the condition of the Falak. The Delhi police have not yet tracked her parents and Rajkumar, who supposedly handed her over to his 14-year-old girlfriend who admitted Falak in the hospital.

We are working towards catching Rajkumar as soon as possible. We are trying to find the parents of the baby, said Deputy Commissioner of Police (south) Chhaya Sharma.

However, police have traced a woman identified as Munni, a domestic maid who left the two-year-old toddler in her employer Laxmi's house in west Delhi.

Munni came to Laxmi's house in September for job, saying that she was a widow and wants to take care of the baby. After working there for around 20 days, she left the place leaving the baby at Laxmi's home.
