# Natural Hendra Virus Infections in Captive Australian Black Flying Foxes, Queensland, Australia

## TL;DR

This study shows that Australian black flying foxes can naturally catch and develop immunity to Hendra virus.

## Contribution

The study provides evidence of natural Hendra virus infection cycles in flying foxes.

## Key findings

- Flying foxes showed Hendra virus infections and associated serology.
- The findings suggest possible reinfection or recrudescence in flying foxes.

## Abstract

We provide evidence for natural Hendra virus infections and associated serology in a cohort of Australian black flying foxes (Pteropus alecto) transferred from Queensland to the Australian Centre for Disease Preparedness in Victoria, Australia. This study supports the likelihood that flying foxes undergo cycles of infection and reinfection and possibly recrudescence.
