Hello dear ,
I read and understand your concern.
I am Dr Arun Tank, infectious disease specialist answering your concern.
Pin
worm infection is caused by
Enterobius vermicularis infection. It is notorious for its reinfection. If all the members of the family is not treated than you are on risk of reinfection.
Pin-worm requires treatment with
mebendazole or
albendazole single dose treatment. If the symptoms is still there second dose at the end of two weeks cures all the infections and you are free from the remaining infection.
Here both you and your daughter are infected so treatment of both the person is necessary. If any one is having infection than it will recurr.
Please adopt good hygienic hand wash practice itching with the hand and re itching will cause you reinfection. Please avoid such a bad practice.
It can also spread via air, so please wash the undergarments effectively this will cure your infection.
You can ask me for further clarification here or you can ask me on bit.ly/DrArun.
Thank you,
Dr Arun Tank
Infectious Disease Specialist
