Thanks for your query.
It is common to get hairloss after major illnessess,and fever
,and even jaundice
Presently you recovered from the disease but may be weak so to recover faster take a healthy diet.
Along with diet take multivitamins and calcium tablets by getting them prescribed by your doctor.
After few days the hairfall will reduce and finally stop.
No other treatment may be needed if you regain back your health.
Hope this answer is helpful.
