  • On 1 December, the United Kingdom of Great Britain and Northern Ireland reported the first case of person-to-person transmission of Zika virus. The case had no history of travel outside the country in the six months prior to symptom onset. The partner of the case had recently travelled to areas which have reported recent Zika virus circulation.

Analysis

  • Overall, the global risk assessment has not changed. Zika virus continues to spread geographically to areas where competent vectors are present. Although a decline in cases of Zika infection has been reported in some countries, or in some parts of countries, vigilance needs to remain high.
