A leading candidate to head the World Health Organization was accused this week of covering up three cholera epidemics in his home country, Ethiopia, when he was health minister — a charge that could seriously undermine his campaign to run the agency.
The accusation against Tedros Adhanom Ghebreyesus was made by a prominent global health expert who is also an informal adviser to Dr. David Nabarro, a rival candidate in the race for W.H.O. director general.
Dr. Tedros, who uses his first name in his campaign, denied the cover-up accusation and said he was “not surprised at all but quite disappointed” that Dr. Nabarro’s camp — which he said included high-ranking British health officials — had switched to running what he called a “last-minute smear campaign.”
The vote for the next director general of the W.H.O. is to take place at a weeklong meeting of the world’s health ministers in Geneva beginning May 22.
Dr. Nabarro, reached by telephone on Saturday in China, said he knew of the accusations — especially because world health officials believe Ethiopia is suffering a cholera outbreak even now, while still denying it — but he insisted that he had not authorized their release.
“I absolutely did not know,” he said.
His adviser, Lawrence O. Gostin, the director of the O’Neill Institute for National and Global Health Law at Georgetown University, called attention to Ethiopia’s long history of denying cholera outbreaks even as aid agencies scramble to contain them. Some of those outbreaks occurred on Dr. Tedros’s watch.
Mr. Gostin said he acted without consulting Dr. Nabarro, and did so because he believed the W.H.O. “might lose its legitimacy” if it is run by a representative of a country that itself covers up epidemics.
“Dr. Tedros is a compassionate and highly competent public health official,” he said. “But he had a duty to speak truth to power and to honestly identify and report verified cholera outbreaks over an extended period.”
In an interview, Dr. Tedros, who was Ethiopia’s health minister from 2005 to 2012 and remains highly regarded for his accomplishments then, denied covering up cholera.
Outbreaks occurring in 2006, 2009 and 2011, he said, were only “acute watery diarrhea” in remote areas where laboratory testing “is difficult.” That is what the Ethiopian government said then and is saying now about an outbreak that began in January.
W.H.O. officials have complained privately that Ethiopian officials are not telling the truth about these outbreaks. Testing for Vibrio cholerae bacteria, which cause cholera, is simple and takes less than two days.
During earlier outbreaks, various news organizations, including The Guardian and The Washington Post, reported that unnamed Ethiopian officials were pressuring aid agencies to avoid using the word “cholera” and not to report the number of people affected.
But cholera bacteria were found in stool samples tested by outside experts. As soon as severe diarrhea began appearing in neighboring countries, the cause was identified as cholera.
United Nations officials said more aid could have been delivered to Ethiopia had the truth been told.
Somalia, which borders Ethiopia, is currently battling a large cholera outbreak, and a new vaccine is being deployed there. Aid officials believe cholera is also circulating in the neighboring regions of Ethiopia, but without confirmation, they cannot release the vaccine. Ethiopia’s health ministry is still calling it “acute watery diarrhea,” and told VOA News last month that it would not change that report without laboratory confirmation, which it said it did not have.
Under the International Health Regulations, which apply to all W.H.O. members, countries must accurately report disease outbreaks. But the W.H.O. can officially report only what countries say. Historically, some countries have tried to cover up or play down outbreaks of human or animal diseases for fear that travel restrictions would be imposed, tourism would suffer or food exports would be curtailed — or simply as a matter of national pride.
The regulations were strengthened after China denied for months in 2003 that it had a serious outbreak of lethal respiratory disease in its southern cities. That outbreak ultimately became known as SARS, for severe acute respiratory syndrome, and spread to several other countries, including Canada.
Dr. Margaret Chan, the current W.H.O. director general, is from China, but was never accused of participating in China’s cover-up. She was the director of health in Hong Kong at the time and led effective responses to both avian flu and SARS.
China has since changed its policy and now is often praised for acknowledging outbreaks promptly, fighting them aggressively and cooperating with other health agencies.
