Why would you let her go to the hospital? You better be right by her side. Spray her down with some Ivermectin spray when no one is around. They will kill her with pneumonia. Make her walk around often. Gently beat on her back and encourage a cough after.
Praying for her. If it goes in her lungs use hydrogen peroxide in a nebulizer- see link. Keep her moving!
Good luck and God bless.
