Doctor :   Hi
Doctor :   How can I help you?
Doctor :   Can you describe the symptoms a little?
Doctor :   Does he have skin lesions such as itching, rashes associated with the symptoms?
User :   How would I know if my 5 year old son had toxocara. He has had an abdominal pain once one morning and was sent home from school. A urinary tract infection which the doctors lost the sample for and has only now been treated with antibiotics after having the infection for two weeks he has had flu like symptoms and a fever which have gone since taking the antibiotic. Are these just symptoms of winter bugs and the uti or could it be toxocara he played with the puppy in october?
Doctor :   Toxocaraiasis is a less common condition which is diagnosed based on evaluation.
User :   No skin lesions
Doctor :   Skin condition such as itching rashes (which often occur at multiple places are much commoner symptoms of toxocariasis.
User :   would he have persistent abdominal pain if he had toxocara? Would a precautionary course of mebendazole be advisable
Doctor :   If toxocariaisis is suspected, then the only means of confirming it is by investigations alone
User :   do you think it unlikely without skin lesions
Doctor :   Elevated eosinophil counts is an early indication of toxocariasis.
Doctor :   if such elevated eosinophil counts are seen on blood test,
User :   what should i do?
Doctor :   then further testing in the form of serum ELISA and monoclonal antibodies against toxocara can be done.
User :   should i have my son tested
Doctor :   Having said this, I do not suspect the condition to be associated with toxocariasis as viral infections are much more commoner and can explain the symptoms too.
Doctor :   However, if you are worried of toxocariasis, I suggest you to get complete blood counts done.
Doctor :   Complete blood counts involve eosinophil counts too,
User :   would it be safe to give mebendazole
Doctor :   and if eosinophil counts are abnormal, then further tests can be done in diagnosing the infection.
User :   how long would it take for symptoms of toxocara to present and would they worse
Doctor :   yes, mebendazole can be used safely, however I suggest that you consult your doctor/pediatrician to prescribing the medication to you.
Doctor :   May I know if any one else in your locality is affected by toxocariasis?
User :   no
Doctor :   Ok
Doctor :   Toxocariasis symptoms develop as the larvae begans to form inside the host.
User :   if he had toxocara would his symptoms be getting worse or better and how long does this take
Doctor :   This transformation is dependent widely upon the host infected and the external temperature.
Doctor :   Ideally the eggs need warm temperature for transformation.
User :   it is very cold here
Doctor :   Thus during warmer temperatures, it can take upto 2-3 weeks for transformation, thus for the symptoms of toxocariasis to occur.
Doctor :   The symptoms and effects produced depend on the resting place of the larvae.
User :   my son played with the puppy 5 months ago and has been fine till now
Doctor :   I do not suggest you to worry regarding this condition./
Doctor :   The likely hood of the infection is less common if you do not have any one
Doctor :   else in the community suffering from the illness.
Doctor :   Again since viral and other bacterial infections are much commoner
Doctor :   and you do not report of associated symptoms,
Doctor :   toxocariasis is unlikely.
Doctor :   Normal blood counts with normal eosinophils are against the features of parasitic infections.
Doctor :   So you can get the test done, if anxious.
