Abstract
Mobile phones, like other inanimate objects, can host germs that cause human infections. Human hands are suitable for harbouring microorganisms that are naturally present in the environment, as well as transient bacteria obtained from the environment It is conceivable that pathogenic microbes could be transferred between human hands and mobile phones.
Mobile phones can act as a reservoir for the development and multiplication of microbes, especially in warm and humid environments; for medical personnel, it can be a way of transmitting hospital-acquired infections. Furthermore, the use of the same mobile phones by medical workers may directly contribute to the transfer of potentially hazardous and nosocomial microorganisms to the general public.
In underdeveloped nations, there is a lack of knowledge regarding potentially harmful germs and hospital-acquired pathogens that can be transmitted amongst healthcare personnel via cell phones. As a result, the current study aims to assess mobile phone contamination among HCWs in various hospital departments, as well as the detection of the presence of the same indicator organism in both HCWs’ hands and cell phones.
This study was conducted in MRI, during the period: from September 2020 till June 2021 which was concomitant with COVID-19 pandemic. Institutional review board approval were obtained prior to samples collection.
The study was conducted on 102 (HCWs) including doctors, nurses and housekeeping who were working in 5 medical and surgical departments among the 32 departments in MRI. All of the HCWs have a smartphone.
Nurses represented the majority of participants representing 68.8%, while the housekeeping was the lowest frequency 14.7 %. The participants among the five departments, the majority of participants were from operation room (24.5%) followed by outpatient clinics (23.5%). While the lowest participants were from endoscopy department (15.7 %).
Gram Positive bacteria were isolated more frequently (85%) than gram negative bacteria (7.8%) in phone swabs. Among the gram positive bacteria, the most isolated bacteria were CONS (39.2%) of phone swabs, followed by S. aureus (24.5 %), MRSA in (12.7%) of swabs. The most detected gram negative pathogen isolated from phone swabs was Pseudomonas spp (3.9 %) followed by E. coli (2.9 %), Klebsiella spp. (1%). While no growth in 92.2% of swabs. Fungi were not commonly detected, both of Candida spp 1.9% and Aspergillus spp 1% were detected in of phone’s swabs .Forty three percent of phone swabs and hand print isolated the same pathogen species. While 14.7 % of phone swabs show no growth and hand print isolated pathogens. But, 41.2% of Phone swabs and Hand print show different pathogens.
Fifty percent of nurses’ phone swabs and hand print isolated the same pathogen species. As well, 40% of house keepings’ phone swabs and hand print isolated the same pathogen species. While 18 % of phone swabs and Hand prints from physicians show the same isolated pathogens.
Staphylococcus aureus were sensitive to Cefoxitin, Amikacin, Clindamycin, Linzeolid, Ciprofloxacin, Levofloxacin, Meropenem, Imipenem and Azithromycin. While MRSA were sensitive to Clindamycin and Linezolid only. Klebsiella and E.coli were sensitive to Meropenem (100%) while Pseudomonas spp. was sensitive to Meropenem by 83% only. There was a statistically significant difference in sensitivity to Amikacin, Merpenem, Impenem and Levofloxacin among gram negative and gram Positive Bacteria.
