Dear Editor-in-chief, This letter is regarding the article by Daoudi et al. entitled “Study of bacterial contamination of mobile phones and stethoscopes in Neonatal Intensive Care Unit” published in International Journal of Pediatrics DOI: 10.22038/IJP.2017.25504.2170 (1). The authors have evaluated the microbial contamination of mobile phones and stethoscopes used by medical and paramedical staff. They reported that 100% of mobile phones and stethoscopes studied by their team showed bacterial contamination. Based on their findings, Daoudi et al. suggested that medical staff should wash their hands with care and use hydro-alcoholic solutions after using mobile phones and stethoscopes.Although the paper authored by Daoudi et al. addresses a challenging issue, it has at least one major shortcoming. The main shortcoming of this paper comes from this key point that the authors were unaware of the effects of electromagnetic fields generated by mobile phones on bacterial resistance against antibiotics which can strongly worsen the bacterial contamination of mobile phones and make it a life-threatening problem. Over the past decade, we have studied the health effects of exposure to different sources of electromagnetic fields such as mobile phones (2-6). While in some cases exposure to mechanical waves such as diagnostic ultrasound could make the antibiotic-resistant bacteria susceptible (7), we showed that bacteria can become more resistant to antibiotics after a pre-exposure to ionizing electromagnetic (8), or non-ionizing electromagnetic radiation (9). In this light, not only bacterial contamination of mobile phones of physicians and medical/paramedical personnel is of great importance, the increased resistance against antibiotics induced by exposure to mobile phone radiation strongly increases the risk of nosocomial infection.
