Dengue severe phase is around 7 days long, when the platelet count drops like waterfall. If her infection has continued for 5-6 days and her count has stayed above 20,000, then she will start recovering on her own.
Give her lots of fluids, juices and multivitamins and get the Blood platelet count done daily. Even the hospitals will be following the same course of treatment. Just in case, make sure that the hospital in Moradabad has Apheresis machines that can provide platelets from donors, if required.
All the best and wish her a speedy recovery. more
