() is a frequent cause of serious health problems with high morbidity and mortality. The risk of infections is increased with the emergence of methicillin-resistant (MRSA). This study aims to determine the nasal carriage rate of both and MRSA among schoolchildren in Sana'a city.
This is a cross-sectional study conducted from January 2018 to May 2020. Five hundred and thirty-six students were enrolled. Their age ranged from 5 to 19 years with the mean age and standard deviation equal to 13.3 ± 3.5 years. Nasal swabs were collected from each student for culturing and methicillin susceptibility testing.
Students with positive culture were 271 (51%) males and 265 (49%) females. was isolated from 129 (24%) students whereas the overall prevalence of MRSA was 8 (1.5%). was significantly recovered from students at the age group of 10-14 years ( = 7.02; =0.03), females than males (OR = 1.96; = 10.75; =0.001), and students who were admitted into hospitals (OR = 1.6; = 4.89; =0.03). Nevertheless, there were no significant differences between MRSA carriage and students' age ( = 2.3; =0.32), gender (OR = 1.02; = 0.001; =0.63), and hospital admission (OR = 1.4; = 0.25; =0.62).
The prevalence of MRSA is low among schoolchildren in Sana'a city. Age, gender, and previous hospital admission were statistically associated with nasal carriage of but not MRSA nasal carriage.
（）是严重健康问题的常见病因，发病率和死亡率都很高。耐甲氧西林（MRSA）的出现增加了感染风险。本研究旨在确定萨那市学童中（）和MRSA的鼻腔携带率。
这是一项于2018年1月至2020年5月进行的横断面研究。共纳入536名学生。他们的年龄在5至19岁之间，平均年龄和标准差分别为13.3±3.5岁。从每名学生采集鼻拭子进行培养和甲氧西林敏感性测试。
培养结果呈阳性的学生中，男性有271名（51%），女性有265名（49%）。从129名（24%）学生中分离出了（），而MRSA的总体患病率为8名（1.5%）。在10 - 14岁年龄组的学生中（=7.02；=0.03）、女性学生中（OR = 1.96；=10.75；=0.001）以及曾住院的学生中（OR = 1.6；=4.89；=0.03），（）的检出率显著更高。然而，MRSA携带情况与学生年龄（=2.3；=0.32）、性别（OR = 1.02；=0.001；=0.63）和是否住院（OR = 1.4；=0.25；=0.62）之间没有显著差异。
萨那市学童中MRSA的患病率较低。年龄、性别和既往住院情况与（）的鼻腔携带在统计学上相关，但与MRSA的鼻腔携带无关。
