was applied, treatment was effective in about one in three cases. As of 2005, there were twelve cases where famciclovir had been used, eight of which were fatal. As a fraction of the overall population, it has been calculated that of the 78 Asian elephants born in captivity in North America between 1978 and 2007, 19 are known to have died of EEHV, and five more were successfully treated with antiviral medication. The affected animals are mostly young Asian elephants that had been born in captivity, with half the cases in North America being between the ages of one and four years (and three-quarters between one and eight years old). Some cases have affected newborns or adult elephants born in the wild (oldest aged 40 years), and three recorded cases have affected African elephants. The first documented fatal case for African elephants was Kijana, an eleven-month-old male in 1996. Since 2008, a number of cases have been attributed to EEHV1 among wild Asian elephants. The first suspected case in Asia was in 1997, though it was not until the fifth suspected case that the presence of the virus could be confirmed. This case was reported in 2006, with the death of a young wild-born female calf at an elephant sanctuary in Cambodia. The virus was identified as part of the EEHV1 group, the same as previously identified in the North American and European captive populations. In 2013, nine lethal cases from India were extensively characterized and found to consist of a wide variety of genetically diverged strains of EEHV1A and EEHV1B matching the subtypes and genetic range of nearly all those found previously in Europe and North America. Cases attributed to EEHV1A and EEHV4 have also been reported in Thailand and there is both confirmed and anecdotal evidence for similar hemorrhagic disease deaths of between 16 and 30 more calves in Asian countries including Thailand, India, Nepal, Myanmar and Indonesia within the past five years. Thus, this is not just a disease of captive elephants, but is endogenous to and possibly rampant in Asian elephants in the wild also. Further research has been noted as "urgently required" to study the situation in regions with wild Asian elephant populations. On 12 June 2019 it was reported that in Chester Zoo the 2-year-old Indian elephant calf Indali Hi Way had fully recovered from EEHV, after numerous treatments over 2 weeks, and that
