Welcome to the forum. Typhoid fever
may get well in 10-15 days in some while it may take a longer period in case of other patients. Healthier patients get well faster if they have a milder infection. Recovery of the symptom depends upon the severity of the disease, general health of the patient, proper medication, adequate rest and a proper diet. The recovery time varies from individual to individual.
I will suggest you to consult your treating doctor. Your typhoid fever had been complicated with malaria
( you mentioned mp positive ). Your general health needs attention, care and rest. It is not necessary but if your general health is still weak typhoid fever may relapse. ( recurrences occur)
Low grade fever
will weaken you further, get clinically examined again. Eat boiled, blanched food ( semi solid ) in nature. Take fruits, berries, green veggies and low fat dairy products. Keep well hydrated.
Enjoy good health, take care.
