Experimental set-up.

Hospitals are highly dynamic environments where Covid-19 is highly transmissible if effective measures are not taken. General preventive policies are not necessarily effective; however, agent-based modelling can offer a way to tailor policies in such specific settings. In this paper, we develop an agent-based model to simulate a hospital as a multi-agent system and examine the influence of well-established Covid-19 factors on transmission, based on the Susceptible-Exposed-Infected-Recovered epidemic model. These factors include the mask efficacy, the mask-wearing percentage, the vaccination percentage, the room ventilation, the distancing rule, and the screening policy. This study, conducted in 2023, simulates agent interactions in a hospital setting using Python. We apply different parametrisations and employ a local sensitivity analysis to isolate the effect of each factor on transmission. We perform statistical analysis using independent two-sample t-tests, with a significance threshold of p
