Since announcement of the Chinese authorities in  Wuhan city on novel corona virus disease (COVID- 19) in December 2019, the epidemic has expanded from Wuhan throughout China and disseminated to every country across the world. As of 10 June, there were 7.5 million confirmed COVID-19 cases and 410 thousand deaths worldwide (Zhang et al., 2020).

COVID -19 infection occurs mainly by contact or droplet transmission. At this time, there are no  specific vaccines or treatments for COVID-19. The ward education is widely regarded as the most suitable method for teaching and has consistently been identified as the preferred place for learning by nurses. Much of the literature refers specifically to those undertaking pre-registration programs and post basic courses. However, with the arrival of word based education selecting the most appropriate venue for learning

This research aimed to assess the potential of active food packaging as an innovative approach to enhance the
quality of fresh food products. Specifically, our focus was on developing chitosan edible films combined with
rosemary nanoemulsion (Ch-RNE) and carvacrol nano-emulsion (Ch-CNE) as effective antibacterial food packaging
solutions. The efficacy of these films against artificially inoculated L. monocytogenes (NCTC 13372\ ATCC®
7644) as a Gram-positive bacterium, and S. enterica serovar Typhimurium (ATCC 14028) as a Gram-negative
bacterium, in ground meat was investigated. The size of the prepared nano-emulsions was characterized using
zeta sizer, FTIR and HRTEM. The MIC of both nano-emulsions against both pathogens was found to be 0.78 %
and 1.56 %. Filmogenic mixtures were casted using these concentrations, which were then dried and evaluated
for their physical and mechanical properties.
