My cousin has severe anemia, fever- doctors can’t do anything for him?

Hi I’m not asking for myself actually. Recently my cousin is in hospital and doctors can not do anything. He has severe anemia. As I know the platelet number was 50.000 when it should be somehow 200.000-400.000. Firstly he had fever for several days and after they took him to hospital it reduced and he was very well for one day. But after that day his situation worsened and he became somehow numb. He didn’t recognise anything but had irritability. Now somehow his memory restored (like he has reflection when you call his name) but he is half unconscious. Now he is in reanimation and doctors can not diagnose certain thing. They say he has liver and spleen dysfunction and he needs blood. That’s all. The other things i think you should know is he’s been to Africa at the end of December. And had fever one time there which has passed easily after antibiotic intake. Also he used drug called Lyrica regularly which i think you should know. I will be really thankful if you can help somehow
