Those at risk of occupational exposure on affected or at-risk farms can be protected via antiviral prophylaxis (oseltamivir) or post-exposure prophylaxis.3.

Measures recommended below aim to protect persons from direct exposure to infected or possibly infected poultry and wild birds and, should this fail, to protect them post-exposure.

There is no evidence to support the role of ribavirin as post-exposure prophylactic treatment for Lassa fever.
