were detected (52.1 per 100,000 inhabitants). this was at the same high level as ob- served in 2014 in denmark (figure 8.13). a case was defined as a person found positive for the first time with a specific mrsa strain regardless whether the patient was infected or colonized only. mrsa isolates were confirmed by detection of either the meca or more uncommonly, the mecc gene. in 2015, the number of new mrsa cases stabilized for the first time since 2009. cc398 cases constituted 39% (n=1,173) of new mrsa cases in 2015, which is a slight decrease compared to 2014 (table 8.6). this decrease was expected to occur at some point, since the intensive screening of people with contact to livestock introduced in the mrsa guidelines in 2012 has detected many cc398 cases in previous years, thus reach- ing a saturation in this sub-population. mrsa isolates carrying mec c were demonstrated in 61 cases (2.1%) in 2015 (9 in 2009, 21 in 2010, 37 in 2011, 24 in 2012, 41 in 2013 and 53 in 2014). thirty-nine of the cases (64%) had infections at the time of diagnosis. only two pos- sible livestock contacts were registered for the 61 mec c cases. the total number of cases and the number of cases presenting with infection according to epidemiological classification are danmap 2015 0 500 1000 1500 2000 2500 3000 3500 1994 1995 1996 1997 1998 1999 2000 2001 2002 2003 2004 2005 2006 2007 2008 2009 2010 2011 2012 2013 2014 2015 number of cases number of cases 3 years moving average 0 100 200 300 400 500 600 2007 2008 2009 2010 2011 2012 2013 2014 2015 no. of infections imported (imp) hospital-acquired (ha) health-care associated, community onset (haco) community -acquired (ca) cc398 figure 8.13. number of methicillin-resistant staphylococcus aureus cases, with a three years moving average, denmark danmap 2015 sab mrsa spa type cc group (a) no. of cases spa type cc group (a) no. of cases no. causing infections (%) t127 cc1 96 t002 cc5 173 94 (54) t084 cc15 89 t127 cc1 148 75 (51) t002 cc5 84 t008 cc8 122 79 (65) t230 cc45 82 t304 cc8 112 46 (41) t091 cc7 60 t019 cc30 90 60 (67) t012 cc30 57 t223 cc22 87 37 (43) t015 cc45 53 t044 cc80 48 22 (46) t021 cc30 46 t437 cc59 44 31 (70) t701 cc8 45 t032 cc22 40 21 (53) t008 cc8 36 t843 cc130 38 21 (55) table 8.5. the ten most prevalent spa types demonstrated in sab and in non- cc398 mrsa cases, denmark 2015 a) cc = clonal complex
