From: Description of a large measles epidemic in Democratic Republic of Congo, 2010–2013
Health Zones in epidemic and on alert for measles, Democratic Republic of Congo, week 34–2011 and week 14–2013. We present two points in time to represent the spatial and temporal evolution of the epidemic. White areas represent health zones (HZ) not in epidemic, yellow areas represent the HZs at risk of epidemic, the red areas represent the HZs in epidemic and the green areas the HZs in post epidemic. In the first map, cross-hatched HZ had been vaccinated between October 2010 and August 2011, in the second, cross-hatched HZ had been vaccinated between January 2012 and April 2013.
