The likelihood of a certain type of Methicillin-resistant Staphylococcus aureus infection — community-associated or hospital-associated — depends on age and season, according to a study in American Journal of Epidemiology.
Researchers analyzed national data on hospitalizations and antibiotic resistance to estimate the magnitude and trends in MRSA infection and hospitalization rates from 2005 to 2009. They found that while the hospitalization rate stayed around the same level, the total number of infections increased.
In addition, hospitalizations related to hospital-associated MRSA were more common in older individuals. Community-associated MRSA peaked in late summer and hospital-associated MRSA peaked in the winter.
