Brief Answer:
Titers suggest ongoing typhoid infection.
Detailed Answer:
Hello, Sir.
I understand your concern.
I have gone through the reports you attached.
As per the results, there seems to be a four fold rise of titers wrt to H antigens, particularly wrt to paratyphi A.
This can point to Typhoid infection caused by Salmonella paratyphi A.
H titers are more significant than O titers.
The increase in titers particularly happens in the 2nd and 3rd week of illness.
You need not worry of this elevation much.
Also, your child is placed on a right antibiotic Cefixime.
You can expect your child to become normal soon.
Post your further queries if any.
Thank you.
