BNGRC has published its situation report for October 27, and again it bears little resemblance to the WHO numbers, which are for October 24.
BNGRC counts cases by recovered (948), under treatment (141) and deaths (64). It also reports 21 new cases today, 30 recoveries, and no deaths. These are reported according to the hospital or district dealing with them. It also lists, confusingly, 62 deaths and 77 cases under investigation at the "community level." BNGRC's numbers total 1,053 plague cases.
WHO, meanwhile, counts 1,309 cases including 93 deaths. It breaks cases down by pneumonic, bubonic, and septicemic, as well as some unspecified (in effect, under investigation). It also lists them as confirmed, probable, and suspected. It also states that "The figures in this report are based on a rigorous data cleaning, verification and analysis process aimed to give a better understanding of the dynamics of the epidemic."
BNGRC gets its numbers, as far as I can tell, from the Ministry of Public Health; presumably WHO does as well. So I have no idea why they don't report the same numbers, at the same time. Neither agency, and no Madagascar media I've seen, have mentioned the inconsistency.
