A nursing student wants to know the differences between hospital-associated methicil-lin-resistant Staphylococcus aureus (HA-MRSA) and community-associated methicillin-resistant Staphylococcus aureus (CA-MRSA)

Question

Which statements about CA-MRSA are true? (Select all that apply.) a. 20% to 30% of the general population are colonized with CA-MRSA.
b. Boils caused by CA-MRSA can be treated without antibiotics.
c. CA-MRSA is less dangerous than HA-MRSA.
d. CA-MRSA does not cause necrotizing fasciitis.
e. CA-MRSA is transmitted by airborne droplets.

Answer 1

A, B, C
CA-MRSA is thought to be present in 20% to 30% of the population, and many of these indi-viduals are asymptomatic carriers. Boils caused by CA-MRSA can often be treated by surgical drainage alone. CA-MRSA is less dangerous than HA-MRSA but more dangerous than methicil-lin-sensitive Staphylococcus aureus (MSSA). CA-MRSA generally causes mild skin infections but can cause more serious infections, such as necrotizing fasciitis. CA-MRSA is transmitted by skin-to-skin contact and by contact with contaminated objects.
