ZIKA VIRUS SITUATION REPORT SUMMARY (June 22, 2016)

Key Findings and Data

• Global Spread: By June 22, 2016, Zika virus was reported in 61 countries and territories through ongoing mosquito-borne transmission. This includes:
  • First outbreaks in 47 countries since 2015, with no prior evidence of circulation, and ongoing transmission.
  • Ongoing or historical transmission in 14 countries previously affected.
  • Evidence of sexual transmission in 10 countries, likely non-vector-borne.
• Health Associations: Zika virus is established as a cause of microcephaly and Guillain-Barré syndrome (GBS) based on scientific consensus. Microcephaly cases, potentially linked to Zika, were reported in twelve countries; for instance, Brazil had 1616 cases.
• WHO Response: The World Health Organization declared a public health emergency, launched a Strategic Response Framework, and emphasized vector control, risk communication, and research. By June 17, 2016, a revised strategy was published for 2016-2017.
• Risk Assessment: Overall risk remains high; the virus continues to spread geographically, with no significant decline reported. PAHO/WHO categorized countries into those experiencing first outbreaks and those with prior transmission.

Additional Notes

• Transmission Variations: Evidence shows sexual transmission in specific countries, and the Asian lineage virus was found in Cabo Verde, raising uncertainty.
• Surveillance and Data: Microcephaly cases were reported worldwide, with interdisciplinary efforts to monitor and respond.

Recommendations and Actions

• WHO focuses on coordinated risk communication, vector control, health system strengthening for affected individuals, and ongoing surveillance to mitigate the virus's impact.
