'How many will die?': the mysterious ailment killing Kenyan elephants

Veterinary officers from the Sheldrick Wildlife Trust and Kenya Wildlife Service attend to a male elephant lying on the ground after falling ill at Kitenden B Community Conservancy in Amboseli this week.

Lying on the ground and kicking up a cloud of dust, the elephant slowly exhausted himself in futile attempts to stand, the latest potential victim of a still-mysterious ailment in southern Kenya.

Distressed vets administered a glucose injection - the only option, given that the cause of the ailment remains unknown - to the 11-year-old male, known as Genghis Khan, who was struggling to breathe.

The mystery affliction has killed at least 19 pachyderms, mostly females or young males, since June in Kenya - with all of the animals exhibiting identical symptoms, including partial paralysis.

Elephant herds have made Amboseli - overlooked by Africa's highest peak, Mount Kilimanjaro in Tanzania - a lucrative tourist hotspot and the mysterious deaths in the region are a sensitive issue in a country where tourism is a huge source of revenue.

"You would find one struggling for a day, struggling for two or even three days. Until they completely die," said Patrick Papatiti, head of operations for Olgulului communal lands, which includes the Kitenden B reserve where Genghis Khan was found.

In late July, the Kenya Wildlife Service (KWS) said toxicology reports found high concentrations of cyanide in the animals' carcasses, suggesting possible pesticide poisoning from nearby farms' crops.

While observers still question the possible cause of death, several specialists dismiss poisoning.

"It's a disease," said Papatiti, who was born and raised in the local Maasai community, insisting there was "no way" cyanide was involved.

He is one of the very few local voices publicly rejecting the KWS preliminary findings, pointing out that no other animals have died.

Notably, neither scavengers nor flies that fed on the supposedly poisoned carcasses have perished - creatures that typically succumb after consuming poisoned animals.

"If another animal feeds on that carcass and it is not dying, then definitely it is not a chemical," Joel Nyika, the Amboseli ecosystem manager for the Kajiado County authorities, said.

He dismisses the theory, also put forward by the KWS, that the cyanide might have come from a type of foliage, noting local livestock would have died as well.

"As wildlife managers, we believe it could be a disease that is only affecting these elephants."
