Wrong babies?

It is has been reported by different studies that 100,000 to 500,000 newborns are accidentally switched at birth every year -- and given to wrong parents! According to the 1998 Edition of the Tanderberg Report, (an annual medical study by sociologist Dr. Morton Tanderberg, and as reported by Ann Victoria in Weekly World News, p. 22, on 9-8-98), 500,000 or 1 out of every 8 babies born in American hospitals is sent home with the wrong parents. In many cases, these oversights are caught and corrected within a few days and the babies are returned to their mothers. But on the other end of the scale, Dr. Tanderberg says that in some overcrowded facilities, particularly in large metropolitan areas like New York, Los Angeles and Chicago, the number of switched babies could be considerably higher -- possibly as high as 3 out of 8.

This is weired because it is happening in USA, you would think something like this happens in Africa.
