Current active Zika virus transmission

Countries and territories are categorised as currently experiencing active Zika virus transmission if local Zika infections have been reported by health authorities within the last 2 months.

This transmission can be further described as:

  • sporadic transmission, if no more than 10 locally transmitted cases have been reported in a single area within this time period, or
  • increasing or widespread transmission, if
    • more than 10 locally transmitted cases of Zika virus are reported in a single area, or
    • at least two separate areas report locally transmitted cases of Zika virus, or
    • Zika virus transmission is ongoing in an area for more than 2 months.

Countries and territories are removed from this list if no new evidence of Zika virus transmission is provided within 8 weeks.

The first declaration of local Zika virus transmission in a country or territory is based on a laboratory confirmed case reported by competent health authority.
