Remdesivir protective in NHP Nipah models within 24 hours of exposure
No direct HeV human data
Early post-exposure window critical
Favipiravir protective in hamster Nipah models
No human data for HeV
May warrant compassionate consideration
Chloroquine not recommended despite in-vitro activity
Animal model failure
QTc risk without benefit
Prevention and One Health strategy
Equivac HeV equine vaccine
Reduces equine cases and therefore human exposure risk
Voluntary in Australia with variable uptake
PPE education for horse workers and veterinarians
Full face shield, N95 respirator, waterproof gown, gloves
No PPE compromise when handling sick horses in endemic area
Biosecurity measures
Prevent horse grazing under flying fox roost trees
Water source protection from bat contamination
Patient Discharge Instructions
copy discharge instructions
Hendra virus infection home care after hospitalization
Complete all prescribed medications as directed
Strict activity rest until cleared by your doctor
Attend all scheduled follow-up appointments
No blood or tissue donation until cleared by public health authorities
Warning signs to return to Emergency Department immediately
New or returning headache, especially severe
Confusion, memory problems, or personality change
Seizures or convulsions
Difficulty breathing or shortness of breath at rest
High fever (temperature > 38.5 degrees Celsius)
Weakness in arms or legs
Vision changes or double vision
Any new neurological symptom at any time within 18 months of illness
Long-term monitoring requirements
Hendra virus can cause delayed brain infection months after your initial illness
Report any new neurological symptom promptly
Scheduled brain MRI at intervals as advised by neurology
Follow-up with infectious disease clinic as scheduled
Follow-up with neurology as scheduled
Occupational and safety considerations
Do not return to working with horses until cleared by your doctor and public health
Ensure all horses in your care are vaccinated with Equivac HeV vaccine
Always use full PPE when handling sick horses in Queensland or New South Wales
Report any sick horse to a veterinarian and public health authorities immediately
Psychological support
This was a serious and rare infection
Psychological counseling is recommended given the high fatality rate in other cases
Contact your GP for referral to mental health support
