Prevalence of Multidrug-Resistant Bacteria on Mobile Phone Surface

With the introduction of multiple uses of mobile phones, including social networking sites, people are being addicted to the device. Most people carry the device to places which are loaded with possible pathogenic microorganisms such as toilets and washrooms, enabling the device to act as a potent fomite.

This study aims to determine the presence of potential pathogenic and multidrug-resistant (MDR) bacteria on the surface of mobile phones used by different occupational groups. It also aims to identify a possible relationship between mobile phone usage in toilets and mobile phone usage while eating.

Two hundred and sixty-eight interviewees belonging to four different occupational groups; 204 students, 24 security staffs, 21 food vendors, and 19 cleaning staff participated in the study in a university, of which 67.54% (n = 181/268) admitted to carry their mobile phones into toilets and 60.07% (n = 161/268) of the total respondents stated that they used their mobile phones while being confined in toilets.

MDR bacterial presence were observed for both case (90.54%, n = 67/74) and control (73.07%, n = 19/26) study of the 100 swabbed samples and the association between usage of the mobile phone while being confined in toilets and while eating by the same respondent were statistically significant (P = 0.00 ≤ 0.05).

The study signifies that mobile phones are carriers of pathogenic and MDR bacteria. Therefore, cleanliness and hygiene issues should be prioritized with an awareness to minimize or restrict the use of mobile phones in unfavorable and unhygienic environments such as toilets and washrooms.
