More details on this epidemic have been published (J Pediatr 2012; 161: 1091-6, editorial 980).  There have been more Pertusis cases than in any period in the past 50 years.  Part of the problem is due to pertusis’ high reproduction number, 92-95% of the population must be protected against pertusis to halt transmission.
