Kwara State is tightening its guard against Ebola and diphtheria. The state government has begun training health workers with a focus on surveillance. The point of the exercise is to catch suspected cases earlier and push reports up the chain faster. Speed matters with both diseases, which can move through a community quickly once they take hold. The push suggests officials see gaps in how cases come to light at the local level. Health workers are usually the first contact a sick person has with the system, so their ability to spot symptoms decides whether detection works. Neither the number of workers trained nor any current case figures were spelled out in the announcement.
