DAX for Measure

[TSK]

I need help in creating measure, I have 3 tables 1) Patient Name 2) Patient Diagnosis 3) Medicene Consumed. I have linked diagnosis and medicene table with Patient Name table via ID. Now I want a measure which can calculate that how many patients are diagnosed as "Fever" and consumed "Panadol" and "Arinac". Below are the tables for reference in this case answer is 2, Patient with ID 1 and 5 are Diagnosed as Fever and Consumed "Panadol" and "Arinac". How can I achieve this via measure.

Patient Name:

ID	Name
1	Ahmed
2	Rafiq
3	Saleem
4	Jospeh
5	David

Patient Diagnosis:

ID	Diagnosis
1	Fever
2	Flu
3	Flu
4	Flu
5	Fever

Medicene Consumed:

ID	Medicine Name
1	Panadol
1	Brufen
1	Arinac
2	Panadol
2	Arinac
3	Panadol
4	Panadol
5	Panadol
5	Arinac

Hi , @TSK 

You may check if the following measure helps.

Measure 1 = 
VAR tab =
    SUMMARIZE (
        'Patient Name',
        'Patient Name'[ID],
        'Patient Name'[Name],
        "flag",
        VAR _id = [ID]
        RETURN
            IF (
                LOOKUPVALUE ( 'Patient Diagnosis'[Diagnosis], 'Patient Diagnosis'[ID], _id ) = "Fever"
                    && "Arinac" IN DISTINCT ( 'Medicene Consumed'[Medicine Name] )
                    && "Panadol" IN DISTINCT ( 'Medicene Consumed'[Medicine Name] ),
                1,
                0
            )
    )
RETURN
    SUMX ( tab, [flag] )

Want to ask one more thing, if I have lots of kind of fever like, fever dengue, fever malaria, fever covid, in that case how can I catch any diagnosis which contains the word fever rather than hard coded "Fever"
