MRSA cases increase by 20 percent in 2012

The Statens Serum Institut said on Wednesday that the number of reported methicillin-resistant Staphylococcus aureus cases increased by 20 percent in 2012.

A total of 1,556 new cases of MRSA were reported, the majority of which were people with no direct contact with hospitals or nursing homes. The number of hospital-acquired cases remained low.

In 2012, cases with MRSA CC398, a pig-related MRSA, continued to increase, and are now recorded separately. Doctors determined that this type of MRSA is spread differently. It if primarily seen in people who work with pigs and their family members, and makes up approximately 15 percent of MRSA cases.

A revised MRSA guideline was published in November 2012 and included pigs as a risk factor for infection. SSI expects attention to the revised guideline to increase the number of diagnosed cases of MRSA CC398.

MRSA is a staph infection that creates a small red bump on the skin, similar to a spider bite. The bumps turn into painful abscesses that require draining by a doctor. In some cases, the bacterium goes beneath the skin and can cause life-threatening infections in bones, joints, wounds, bloodstream, heart valves and lungs, according to the Mayo Clinic.

SSI is a part of the Danish Ministry of Health. It conducts international research, production and service enterprise to prepare for infectious diseases and congenital disorders.
