Efficacy of biocide-based sanitizer in daily use during the COVID–19 pandemic

BackgroundThe objective of this study was to evaluate the effectiveness of a biocide-based disinfectant against pathogenic flora on the skin of the hands.Material and methodsThis is a prospective study of 30 participants from the general population. The questionnaire, interview data and results of two swab analysis were collected. All the data were statistically analysed.ResultsThe results showed that after the hand disinfection with the biocide based disinfectant, number of colonies on the participants’ skin decreased or completely disappeared, and a significant correlation was found between the number of colonies before and after disinfection. In case of Coagulase – negative staphylococcus the number of Colony – forming unit (CFU) significantly decreased [p<0,001]. Also Bacillus ssp. and Acinetobacter spp. were also found in 17.6 % (n=3) of the cases after the disinfection however the number of the colonies was significantly decreased [p=0,001; p=0,008].ConclusionsOur study demonstrates that a biocide-based disinfectant has high effectiveness against Gram positive, Gram negative, as well as fungal pathogens
