Vanuatu Outbreak Alert System

What is the Vanuatu Outbreak Alert System?

The Vanuatu Outbreak Alert System (VOAS) informs the public about outbreaks or increases of communicable diseases.

VOAS has four alert levels:

  • Level 0: Low
  • Level 1: Medium
  • Level 2: High
  • Level 3: Very high

Each level describes the measures that members of the public need to take based on the risk level. Levels are set by the Ministry of Health. The public must follow the appropriate measures indicated.

VOAS was developed in 2021 to support COVID-19 response. Although the current focus is COVID-19, the system has been designed to extend to other communicable diseases if needed. These may include leptospirosis, dengue and cholera. The Ministry of Health will advise the public on which diseases are covered by VOAS.
