WWII inspired posters

I think this is propaganda that's using the "Activate Emotion" Technique because its using the image of nurses and doctors who are at the "frontlines" trying to combat the COVID-19 virus, and is trying to direct the audience to be more mindful about the spread starting from home in order to help those nurses and doctors. I think this is beneficial, its not spreading negative information, it does play on human emotions, specifically sympathy but I don't think it's harmful and ultimately it leads to a goal that benefits public health while not causing hysteria amongst the population.
