MRSA
Methicillin-resistant Staphylococcus aureus (MRSA) is a form of the Staphylococcus aureus bacterium that is resistant to antibiotics and as a result is very difficult to treat. MRSA now kills more Americans every year than HIV/AIDS, and the rates of infection are rising.
Methicillin is an antibiotic that was introduced in the 1960s as a way of combating the Staphylococcus aureus bacterium that is ubiquitous in hospitals. Within a year, doctors began finding strains of bacteria that had already developed immunity to methicillin. By the 1990s, MRSA had become the leading hospital-acquired skin infection in the United States. At the same time MRSA started appearing outside of hospitals. These were different strains of the bacteria, but just as dangerous, and spreading just as quickly. In the past 15 years, MRSA bacteria have become ubiquitous not only in hospitals, but in gyms, locker rooms, swimming pools, and any other settings where human contact is common.
Researchers in Ireland are developing a technology that may significantly halt the spread of the hospital-associated MRSA bacteria. They have developed a textile consisting of nanomaterials 1,000 times smaller than a human hair; these textiles are shown to halt the spread of infection and can be used for linens, drapes, and upholstery in hospitals. The potential for this technology to reduce the instances of hospital associated MRSA is staggering.
You can reduce your risk for community-associated MRSA infection by regularly washing your hands, covering all open wounds with a clean bandage, and not sharing any personal items like razors or towels.
As used in the second paragraph, what does the term ubiquitous mean?
-
A
Indigenous
-
B
Often ignored
-
C
Found everywhere
-
D
Dangerous
In the context describing MRSA's spread through hospitals and community settings, ubiquitous means found everywhere, pervasive presence across multiple environments.
A) Indigenous
Indigenous refers to native origin within a specific region, unrelated to widespread distribution. MRSA isn't described as native to hospitals; it's an introduced pathogen that became pervasive.
B) Often ignored
Ignorance concerns human awareness, not physical presence. The passage emphasizes MRSA's visibility through rising infection rates and mortality statistics, contradicting "ignored" characterization.
C) Found everywhere
Found everywhere precisely captures ubiquitous's meaning in epidemiological contexts: MRSA became "the leading hospital-acquired skin infection" by the 1990s, then spread "outside of hospitals" to "gyms, locker rooms, swimming pools, and any other settings where human contact is common", demonstrating pervasive environmental presence.
D) Dangerous
Danger describes threat level, not distribution pattern. While MRSA is dangerous, ubiquitous specifically addresses its spatial prevalence across environments, not its virulence.
Conclusion
Contextual analysis reveals ubiquitous operates as a spatial descriptor tracking MRSA's expansion from hospital confinement to community saturation. Only "found everywhere" captures this connotation of pervasive environmental presence across multiple settings where human contact occurs.
