If you've been wondering how Tula-Tu is doing, the news is good. The Oregon Zoo's elephant calf is holding steady after a week and a half of emergency care, and Dr. Carlos Sanchez, the zoo's director of animal health, said her viral load is trending down.
Tula-Tu's infection follows a loss the zoo knows well

She's also been out and about. Tula-Tu spent time with dad Samson and aunties Sung-Surin and Chendra, and she's been playing with a large blue ball that used to be her mom Rose-Tu's.
- Status: guarded, with white-cell counts nearly back to normal
- Strain: EEHV-1B, not the 1A her vaccine targets
- Treatment: antivirals, fluids and plasma transfusions
- Blood tests: Oregon State, Baylor and the Smithsonian's lab
“We do not know whether the EEHV-1A vaccine is protective for the -1B variant.”
Her shot targeted EEHV-1A, and Sanchez said the blood samples will help researchers understand how the vaccine responds.
EEHV is a serious threat to young elephants
- 1 to 8
- age range when calves are most susceptible
