The WHO is concerned Tanzania may be hiding Ebola cases

The WHO is concerned Tanzania may be hiding Ebola cases

On Saturday, the World Health Organization issued an unusual news alert: It essentially chastised the government of Tanzania for not responding to requests for information about possible Ebola cases within its borders.

Amid an Ebola outbreak in the Democratic Republic of Congo, WHO said that it learned — through unofficial channels — about three recent cases in Tanzania. The country took four days to respond to WHO’s initial ask, eventually denying that it has identified any Ebola and declining to share its lab data.

“Despite several requests, WHO did not receive further details of any of these cases from Tanzanian authorities,” the press release stated.

Ebola is a “notifiable disease,” according to the International Health Regulations, an international treaty that governs global health emergency responses. Under the IHR, WHO member countries are supposed to report cases of notifiable diseases to WHO within 24 hours of identifying them. Countries are also obliged to share details of their investigations, and even lab tests with WHO for validation.

Tanzania is a WHO member country, but it didn’t follow protocol, the organization says.

If Ebola did make its way to Tanzania, it wouldn’t be entirely surprising. The outbreak in nearby DRC has lasted more than a year, killed more than 2,000 people, and already spread to Uganda. That’s why the WHO is already urging countries in the region to get ready for potential outbreaks.

But the fact that WHO has gone public about its concern over Tanzania has Ebola cases is significant. “It shows how seriously the WHO is taking the possibility of Ebola cases in Tanzania, and how much of a priority they are placing on full transparency about the identification of cases,” Tom Inglesby, director of the Center for Health Security of the Johns Hopkins Bloomberg School of Public Health, told Vox.

A WHO spokesperson said the agency “is mandated by the IHR to inform member states of issues of concern. It is also committed, via its constitution, to help countries respond to health emergencies.” But without more information from Tanzania, doing so will be difficult.

There’s another reason to be concerned: One of the major reasons West Africa’s 2014-2016 Ebola epidemic became the largest in history was that the virus turned up in countries that had never been affected by Ebola. Tanzania would be another country that’s never battled Ebola. If it has been hiding Ebola cases, this could be the start of another challenging, deadly outbreak.

What led WHO to go public about Tanzania’s possible cases

In the WHO’s news alert, the agency described a series of attempts at trying to get information from Tanzania about possible Ebola cases, and the Tanzanian health authorities’ repeated unwillingness to comply.

  • On September 10, the WHO learned of a suspected Ebola death in Dar es Salaam, Tanzania’s largest city and former capital. That individual’s personal contacts were reportedly put under quarantine. At that point, WHO says it immediately sent Tanzania a request for information.
  • A day later, WHO didn’t get any word from Tanzanian officials but it learned — again through unofficial channels — that the Tanzanian National Health Laboratory had tested that initial case positive for Ebola.
  • WHO also learned of another suspected Ebola case in Mwanza, a northern port city in Tanzania. This second case reportedly later tested negative for Ebola.
  • By September 12, WHO was informed of a third patient who had been admitted to a hospital in Dar es Salaam with suspected Ebola.
  • On September 14, four days after WHO first reached out — an eternity in a potential outbreak situation involving a notifiable diseases — Tanzania responded to WHO’s request, saying they had no confirmed Ebola cases. The WHO also learned that Tanzania’s health authorities were not considering seeking the necessary confirmation testing for Ebola at a WHO lab, despite the organization’s urging.
  • On September 19, WHO learned that a contact of the person in the initial possible case was sick in hospital. Again, the WHO asked for information and to verify the person’s lab tests. The response WHO reportedly got: “the United Republic of Tanzania does not have any EVD case” and does not “have any suspected case admitted anywhere.”

According to the WHO spokesperson, as of Monday, the situation hadn’t improved. “Despite several requests, WHO has so far not received the information required to fully assess the potential risk posed by this event,” they said.

It’s possible there are no confirmed cases in Tanzania — but there’s no way to know that for sure without them handing over their lab tests to WHO for confirmation. It’s also possible they’re hiding cases, potentially for fear of travel and trade repercussions. Either way, “it’s the ambiguity that’s a very serious matter internationally,” said Inglesby.
