Mumps in Ireland, 2004-2008

Following a national mumps outbreak that began in November 2004 and continued into 2005, the number of mumps notifications in Ireland waned in the latter half of 2006 and during 2007 (Figure 1). However, mumps notifications have started to increase again in 2008 (Figure 1). The number of mumps notifications annually between 1988 and 2008 and the number of confirmed mumps notifications by year from 2004 to 2008 are shown in Figure 2. In total, there were 420 mumps notifications in 2004, 1,079 in 2005, 427 in 2006, 150 in 2007 and to date there are 153 notifications in 2008 (Figure 2). In contrast, there were 40 mumps notifications in 2003 (Figure 2).
