st: Combining 7 variables with the same output into a single frequency table

[Astha Ramaiya <aramaiya@ihi.or.tz>]

Dear Nicholas, 

I have 7 different variables (fever 1, fever 2, fever 3….fever7) with the same output (0=No, 1 = Yes). I want to combine all these variables so that i can calculate prevalence of the morbidity. For example: 

Fever 1-7 give the output: 

 m_fever1 |      Freq.     Percent        Cum.
------------+-----------------------------------
          1 |         50       14.3       14.7
          2 |        300       85.7      100.00
------------+-----------------------------------
      Total |        350      100.00


 m_fever2 |      Freq.     Percent   Cum.
------------+-----------------------------------
          1 |         0       	0      	 0
          2 |        350      100.00      100.00
------------+-----------------------------------
      Total |        350      100.00

 m_fever3 |      Freq.     Percent        Cum.
------------+-----------------------------------
          1 |         100       28.6       28.6
          2 |        250       71.4      100.00
------------+-----------------------------------
      Total |        350      100.00

How can i combine the 3 tables above to give me the following table? 

 m_fever |      Freq.     Percent        Cum.
------------+-----------------------------------
          1 |         150       14.3       14.7
          2 |        900       85.7      100.00
------------+-----------------------------------
      Total |        1050      100.00

I have been trying to find something the entire day but haven't been successful. Any help would be very much appreciated.

Regards, 

Astha.
