Iconfinder gives away over 300 vector icons on hand washing and hygiene measures
Iconfinder is a website specialized in vector icons, formed by an international team of designers based in Copenhagen, Denmark. It brought together a group of designers to generate a pack of over 300 Covid-19 related free icons. You will find packages with topics such as hand washing, hygiene recommendations and social distancing.
The icons are available in PNG and SVG formats (to scale any size in vectors). They come under the Creative Commons BY-SA 3.0 license, and you'll find icons of many different design styles.
You can use them in your communications and designs, such as flyers, notices and all the material you must design to spread information and raise awareness. Remember to look for information on reliable and official sites of health institutions, such as the World Health Organization.
