Question

The population of a city was 145,000 on March 30, 2004. The number of new cases of TB occurring between January 1 and June 30, 2004 was 19. The number of active TB cases according to the city register on June 30, 2004 was 211. The point prevalence on June 30, 2004 was:

		211
		19
		144.789
		144,981

Answer 1

Answer ; 144.789

Reason ; Here the active TB case on the date of June 30, 2004 was 211
The population of city at march 30, 2004 would be 1,45,000
( The population should be raised slightly at the date of June 30 )

To calculate the point prevalence the above two values are divided as follows,
= 211 / 145000 x 100,000  
It would give the rounded value of 145.
