I am confused about those difference between them.
36714388 Influenza caused by seasonal influenza virus
37394478 Influenza due to seasonal influenza virus

Also I tried to figure out them on SNOMED -CT, but only ’ Influenza caused by seasonal influenza virus’ is found on SNOMED-CT.

Please tell me about them.

Thank you in advance.

@Aelan:

Yeah, that’s something that does happen, even though very rarely: Duplicates in SNOMED. The first one is SNOMED International, and it’s the one you should use. The second one is from SNOMED UK. It will eventually be de-duplicated and removed.

How do you know which is the right one? Unfortunately we don’t have a good way for that. Here are the tricks I am using:

  • Check the concept_code. The shorter one is the SNOMED International one. This will make you pick 36714388.
  • Check the hierarchy in CONCEPT_ANCESTOR. Usually, the good concept has lots of ancestors and descendants, the bad one doesn’t. In this case this doesn’t work, both ancestors and descendants are identical.

Thank you for your good advice.
