Staphylococcus aureus nasal carriage among medical students

Abstract

transmission of S aureus to patients, with the caveat that their knowledge of standard infection control measures is poor during the early years of clinical practice, raising the possibility of transmission during this period. Meticillin-resistant Staphylococcus aureus (MRSA) was isolated in two preclinical students.Our findings emphasise the importance of education on standard infection control measures in medical schools as part of global and national action plans to address antimicrobial resistance. 4,5 Further studies are needed to determine the role of S aureus nasal colonisation in medical students in nosocomial transmission.We declare no competing interests. FC-T is founded by a FPU PhD scholarship from the Spanish Ministry of Education, Culture and Sport (FPU15/01930).

Nasal colonization by methicillin-sensitive and methicillin-resistant Staphylococcus aureus among medical students

“…None of these factors were found to play a significant role in S. aureus nasal colonization. This is in agreement with most other studies which reported no correlation between S. aureus nasal colonization and clinical exposure [29,31,33,43,47,48,54,55]. To the contrary, some studies suggested possible correlation between clinical exposure and S. aureus nasal colonization [35,44,49], while a few studies suggested strong correlation [56,57].…”

Carriage of Staphylococcus aureus among Portuguese nursing students: A longitudinal cohort study over four years of education

“…However, the number of students that were colonized at some point during the four years increased considerably (72%). This value was much higher than the rates reported among medical students in other European countries, namely in France (27%) [ 20 ], Spain (35%) [ 21 ], Austria (25%) [ 22 ], and Bosnia (11%) [ 23 ] or in other continents, namely in the USA (16%) [ 24 ], Malaysia, Taiwan and Japan (10–36%) [ 25 – 27 ] and Colombia (25%) [ 28 ]. These differences may be due to the fact that the present study included a considerably higher number of screening time points (n = 14) compared to the previous studies; most were cross-sectional and therefore performed at a single screening point and the few prospective longitudinal studies usually evaluated the nasal carriage up to three time points.…”

MRSA nasal carriage among Taiwanese senior high school students and a narrative review of local metadata

“…This study investigated MRSA carriage in Taiwanese male high school students during the later stages of the COVID-19 pandemic. The study discovered that 50% of the students had S. aureus in their nasal passages, and 7% carried MRSA — a rate higher than what is typically reported among healthy adults [ 36 , 37 , 39 , 40 , 42 ]. The most common MRSA genotype was ST45, which differs from the previously recognized ST59 Taiwan clone.…”

“…Given that high school students are nearing adulthood, we also reviewed comparative studies on S. aureus nasal carriage among healthy adults in various countries and the details are provided in Table 3 [ [36] , [37] , [38] , [39] , [40] , [41] , [42] ]. The prevalence of S. aureus nasal carriage among healthy adults has been reported to range from 7.4% to 32.4%, while MRSA colonization rates remain low, at approximately 0.12–7.4% across various countries.…”
