Need help reset count

Hi All,

I've tried to calculate the total infected and recovered users every month, the total recovered doesn't matter but the total infected when the same users are infected again after recovery the calculation doesn't work.

 

My table:

 

This is my DAX for it: 

CountInfected =
VAR CountIf = CALCULATE(DISTINCTCOUNT(Summary[User]),Summary[Infected]=1)
VAR CountRec = CALCULATE(DISTINCTCOUNT(Summary[User]),Summary[Recovered]=1)
RETURN
IF(CountIf=CountRec,0,CountIf-CountRec)
 
I would like Total Infected is 1 not 0
 
Many thanks if any of you can help me!

    I'd recommend looking at whatever the last status was.

     

    Try something like this:

    CountInfected =
VAR LastStatusDates =
    ADDCOLUMNS (
        VALUES ( Summary[User] ),
        "@LastStatusDate", CALCULATE ( MAX ( Summary[Date] ) )
    )
RETURN
    SUMX (
        LastStatusDates,
        LOOKUPVALUE (
            Summary[Infected],
            Summary[User], Summary[User],
            Summary[Date], [@LastStatusDate]
        )
    )

    Anonymous based on the data seems like everyone is recovered, how you expected answer to be 1

    AlexisOlson got it. I missed that. Thanks for pointing that out.

     

    Anonymous Here is a measure.

     

    Total Infected = 
VAR __table = TOPN ( 1, ALLSELECTED ( 'Table' ), CALCULATE ( MAX ( 'Table'[Date] ), VALUES ( 'Table'[User] ) ), DESC )
VAR __totalInfected = 
CALCULATE ( 
    SUM ( 'Table'[Infected] ), 
    KEEPFILTERS ( __table )
) -
CALCULATE (
    SUM ( 'Table'[Recovered] ),
    KEEPFILTERS ( __table )
)
RETURN IF ( __totalInfected  > 0, __totalInfected )
