My 1 year old son was getting fever every month for 2 -3 days( january, february, march) . this time we got to get blood tests done. cbc and urine test is normal. typhoid is typhi 0 1: 160 , typhi h 1:80. What can be the reason. we give him home cooked food and boiled water. he got his typhoid vaccine also at 9 months. then how can it be possible to get typhoid. i am getting very worried. he is not eating/ drinking anything.
