The true number of Ebola cases in Congo is at least double, and possibly four times, the official tally, the World Health Organization's emergencies chief said on Tuesday. "We think, with some of our support and modelling, the scale of the outbreak is at least 2-4 times the number of cases we are finding," Dr Chikwe Ihekweazu, Executive Director of the WHO's Health Emergencies Program, told reporters in Geneva after a visit to eastern Democratic Republic of Congo, according to Reuters.
