Resúmen

Deskripshon

English: When a critical portion of a community is immunized against a contagious disease, most members of the community are protected against that disease. This is known as "community (or 'herd') immunity." The principle of community immunity applies to control of a variety of contagious diseases, including influenza, measles, mumps, rotavirus, and pneumococcal disease.

The top box depicts a community in which no one is immunized and an outbreak occurs. In the middle box, some of the population is immunized but not enough to confer community immunity. In the bottom box, a critical portion of the population is immunized, protecting most community members.

not immunized, healthy

immunized, healthy

	16:38, 30 mart 2020	784 × 962 (436 KB)	Gretarsson	Sorry, I have to upload another version because the code of the last one was not valid according to W3C because of double ID occurrences (these fuing IDs are so fuing annoying when revising code by text editor): When I inserted the additional lines in the Dutch text, I c-&-pd the respective text and span elements, and didn’t mind to change their IDs...
	16:18, 30 mart 2020	784 × 962 (436 KB)	Gretarsson	Added width and height information to the svg tag; deleted property and value 'white-space:pre' from switch tag because it caused an offset of the labels in the original file view; revised Dutch labels in order to make the text fit better between the left and right graphic elements (inserted one more line below the fat black arrow in the middle and lower panels); made some minor formal edits (minor improvements of the code structure for better readability)
	23:08, 27 mart 2020	512 × 629 (436 KB)	Gretarsson	sorry, my bad, the last version was a test version, nor the Catalan text is correctly adjusted/justified
	23:02, 27 mart 2020	512 × 629 (439 KB)	Gretarsson	minor adjustments in English (word "contained" was missing in the lowest panel) and Catalan translations
