My father (age 52) was diagnosed with weakly positive malaria 2 months back as well as typhoid and he was given arthemeter tablet. The major symptoms he was suffering from are fever all day long and trouble in bowel movement and stomach irritation. The temperature changed again and again. Also he feels his head spinning as the temperature rises. He also took sulphadoxin for malaria. The doctors stressed on typhoid and he took stronger antibiotics monocef for it for 10 days. His problem in the stomach was cured and today his typhoid reports were negative but he is now diagnosed with vivax malaria . He had given up cereals in his diet and is now on a very low diet and his weight has drastically reduced. Now he has taken primaquine and is now looking for a medicine that works against the resistive strain of vivax. Please help me in right diagnosis and cure.
