And the studies even state that there is no increase in nosocomial infection from artificial vs long natural. So short artificial should be ok
Short natural nails are what healthcare providers should have. That's what policies require in most institutions anyways. Short artificial IS NOT OK because they still promote the growth of microorganisms that real nails don't. Until you can prove that the increased amount of pathogens on your hands doesn't pose a health risk, you have to err on the side of caution and deal with having real nails. PLease read this from the CDC. Length is not the issue. You can stop biting your nails, you can't stop your fake nails from harboring pathogens.
.... HCWs who wear artificial nails are more likely to harbor gram-negative pathogens on their fingertips than are those who have natural nails, both before and after handwashing (347--349). Whether the length of natural or artificial nails is a substantial risk factor is unknown, because the majority of bacterial growth occurs along the proximal 1 mm of the nail adjacent to subungual skin (345,347,348).
Recently, an outbreak of P. aeruginosa in a neonatal intensive care unit was attributed to two nurses (one with long natural nails and one with long artificial nails) who carried the implicated strains of Pseudomonas spp. on their hands (350). Patients were substantially more likely than controls to have been cared for by the two nurses during the exposure period, indicating that colonization of long or artificial nails with Pseudomonas spp. may have contributed to causing the outbreak. Personnel wearing artificial nails also have been epidemiologically implicated in several other outbreaks of infection caused by gram-negative bacilli and yeast (351--353). Although these studies provide evidence that wearing artificial nails poses an infection hazard, additional studies are warranted.
