Correct. Methicillin-Resistant Staphylococcus aureus (MRSA) may result in serious damage or death because it is resistant to commonly used antibiotics, making infection difficult to eliminate.
MRSA is a new more virulent type of bacteria invading hospitals.

Incorrect. Like other bacterial strains, the symptoms during infection by different MRSA strains vary in severity and how easily they are transmitted to others. However, MRSA strains have one dangerous trait in common. Try again.
Question 1 of 2
MRSA is resistant to treatment with most common antibiotics.
Why is infection by MRSA a greater health concern than many other infections?

MRSA has spread from hospital to community environments.
Incorrect. This behavior may promote the spread of bacteria, but does not explain an increase in the presence of MRSA bacteria over other bacterial strains. Try again.
Correct. While poor hygiene and improper hand washing contribute to the spread of all bacteria, an antibiotic is designed to kill infecting bacteria. Widespread use of antibiotics, particularly when patients discontinue treatment early before all bacteria are killed, selects for the growth of bacteria already resistant to antibiotics. The rise in prevalence of bacterial strains like MRSA is a direct result of repeated antibiotic selection for survival of MRSA over other bacterial strains.
Question 2 of 2
inadequate hand washing by healthcare personnel
widespread use of antibiotics
Which of these environmental agents is MOST responsible for the prevalence of MRSA?
