Shanghai studio JWDK creates posters to help fight against coronavirus, inspired by vintage Chinese public health notices

With a theme of 'Stay Clean, Stay Strong' and a palette of soft colours, the four artworks are to help companies maintain good hygiene in and around the workplace. It comes after many workers return to their offices after a long period of homeworking due to the Covid-19 outbreak.

Each poster touches on a different workplace theme, echoing advice laid out by the Chinese government and the World Health Organisation. The first reads, "Make it a team effort! Covid-19 Stay Clean, Stay Strong" – encouraging everyone to take individual action to stop the spread of germs and demonstrates that "every little helps" in the fight against infection.

Another says, "Get a handle on virus prevention. Covid-19 Stay Clean, Stay Strong", a reminder to wash your hands after touching well-handled objects. The third urges people to have better habits of hygiene in shared workspaces and offers suggestions of things that can protect against infection. While the final poster reads, "Your hands are your first line of defence. COVID-19 Stay Clean, Stay Strong" – telling us to sing Happy Birthday twice when washing our hands thoroughly.
