Because they may increase morbidity, death, and healthcare expenditures, HAIs are a serious problem. Finding a solution that is affordable, easily accessible, user-friendly, and environmentally friendly is a good method to deal with this issue. Sodium Dichloroisocyanurate (NaDCC) is one such remedy. Due to its great efficacy against a variety of pathogens, sodium dichloroisocyanurate (NaDCC), a commonly used disinfectant, has gained importance recently. NaDCC, the active ingredient in Ef- Chlor BIO-TAB/ Effi- Sept/ Effi- Kleen (1.67 mg), is extremely effective in eliminating almost all known microorganisms. The World Health Organization (WHO), the European Union (EU), and the United States Environmental Protection Agency (US EPA) have all given their approval for the use of NaDCC as a disinfectant. Gram's staining method was employed in this experiment to identify the bacteria and to identify fungus lacto phenol cotton blue stain is used that cause HAI, and Agar- well diffusion method was used to determine the antimicrobial activity of the tablet. When tested against diverse surfaces, the product was found to be 99.99% effective against E. coli, Shigella, MS2 phage, Staphylococcus, Streptococcus, Aspergillus, etc.
