Mosquito surveillance report

The department conducts mosquito surveillance throughout the Victorian mosquito breeding season, which in inland areas typically occurs from early November through to late April the following year, with coastal areas typically starting earlier and ending later. 

The reports contain a range of indicators relating to mosquito-borne diseases actively monitored by the department. 

The indicators used in these reports are sourced from the following surveillance systems:

  • Human surveillance (notified confirmed and probable cases and/or modelled predictions of vector-borne disease)
  • Mosquito surveillance (adult mosquitoes)
