One of the places you can get free professionally designed infection control images is the website for Webber Training, an organization committed to infection prevention education. You can download the images directly from Webber Training’s website.
Once you choose an infection control image, click on it to enlarge the view or to download it as it is in the JPG version. However, if you wish to adjust the resolution of the image and get a PDF, click on the Print Resolution Tab positioned next to the image. Printed images are also available in A4 size upon request. Downloading the files is entirely legal, according to Webber Training.
