A two-year-old Asian elephant calf, named Indali Hi Way, has made what keepers are describing as a ‘remarkable recovery’ after undergoing intensive treatment for the EEHV virus.
The baby elephant was seen splashing with her herd at Chester Zoo this week, and experts say she has now made a full recovery from the deadly virus which threatens Asian elephants globally.
Indali’s is thought to be a rare case of an Asian elephant surviving the lethal EEHV illness, which is also known as elephant endotheliotropic herpesvirus.
A large team of specialists continue to watch her closely, and the zoo’s conservationists are wary of the possibility that the disease might return in the future.
Her successful recovery to date is, nonetheless, a momentous and historic step for Chester Zoo and for global conservation efforts.
Chester Zoo conservationists have hailed the ground-breaking developments in early detection and treatment methods – developed in partnership with the Animal and Plant Health Agency (APHA) and the University of Surrey – which enabled them to save the young calf.
Keepers, vets and scientists were able to detect the virus earlier than ever before, thanks to high-tech, on-site blood testing techniques.
This meant specialists began treatment prior to Indali showing any outward signs of illness.
During an intensive two-week period, Indali received round-the-clock care to help her fight for life.
This included nine anaesthetic procedures, blood plasma transfusions, interferon therapy, anti-viral medications and immune boosting treatments as well as very large amounts of intravenous fluids.
On 2nd April 2019, treatments ceased as experts believed she had entered a recovery phase.
Now, after closely monitoring her for two months, conservationists have declared her recovery complete.
During her recovery phase, keepers at Chester Zoo have been helping Indali and the herd return to a normal daily routine.
The team have observed that Indali benefitted greatly from reconnecting with the rest of the close-knit family herd, called the Hi Ways.
She has spent much of her time with her mum, Sundara, and can often be seen playing with her 18-month-old half-brother, Anjan.
The rest of the multi-generational herd has also been seen closely supporting Indali, including her grandmother Thi.
EEHV is a major threat to the long-term survival of endangered Asian elephants. Reports of wild elephant fatalities in India, Nepal, Myanmar and Thailand are on the rise.
It is known to have caused deaths in nine countries across their native range, as well as in zoo breeding programmes worldwide.
It is thought that most Asian elephants carry EEHV, but only young calves tend to develop outward symptoms, typically around weaning age. When they do, it is usually fatal.
A team from Chester Zoo, the APHA and the University of Surrey – backed by more than £240,000 in public donations to the zoo – have been at the forefront of attempts to find a solution.
The ultimate goal is to develop an effective vaccine that could be rolled out worldwide.
Dr Mark Pilgrim, CEO at Chester Zoo, said: “Asian elephants are an endangered species and a world without them is unthinkable.
“We cannot underestimate the threat EEHV poses to their future survival. But Indali, wonderful little fighter that she is, and her incredible survival story, has given us enormous hope.”
He added: “Her recovery is a major milestone for conservation. Only two years ago, the global search for a solution to the EEHV crisis looked unlikely to bear fruit. Now, there is light at the end of the tunnel.”
Dr Pilgrim continued: “Although we are still unable to grow the virus in a lab, our team are exploring new avenues of biomedical science based on characterising the proteins produced by the virus and determining the response to them by the elephant’s immune system.
“This is bringing us closer to the development of a vaccine.
“And now, the early detection methods we’re already deploying in the zoo – alongside the innovative treatment programme – have delivered remarkable results.
“We are eternally grateful to the incredible work of the Animal and Plant Health Agency and experts at the University of Surrey, who have been battling against EEHV side-by-side with us for many years now.
“Indali would not be alive today without this conservation partnership.
“Crucially, we must also thank each and every person and organisation who has donated to the zoo’s Never Forget campaign in recent years.
“Overwhelming public generosity has contributed more than £250,000 to the research fund, accelerating our progress and getting us closer to a vaccine quicker than we ever thought possible.
“Supporters right across the country are part of this ground-breaking conservation journey.”
Chester Zoo is hosting its third annual Summer Stampede fundraising event on Sunday 11th August 2019.
Supporters at the zoo and across the country are invited join in a nationwide sponsored walk, raising money for the Never Forget campaign, which continues to fund EEHV research.
