Zika Virus – Global Epidemiological situation as of 16 September 2016

___

Since 1 February 2016, Zika virus infection and the related clusters of microcephaly cases and other neurological disorders constitute a public health emergency of international concern (PHEIC).

Since 2015, and as of 15 September 2016, there have been 64 countries and territories reporting mosquito-borne transmission.

According to WHO and as of 15 September 2016, 20 countries or territories have reported microcephaly and other central nervous system (CNS) malformations potentially associated with Zika virus infection or suggestive of congenital infection.

 

Update on the number of cases

  • The USA
    • Twenty-two new locally acquired cases have been recorded in Florida over the past week.
    • To date, 78 locally-acquired and 650 imported cases of Zika have been reported in Florida.
    • The distribution of the locally-acquired cases is as follow:
      • 71 in Miami-Dade,
      • five in Palm beach,
      • one in Pinellas and
      • one in Broward.
  • Malaysia
    • Six cases have been reported by national authorities between 1 and 13 September.
  • Singapore
    • As of 15 September 2016, the Singapore National Environment Agency (NEA) records 355 locally-acquired ZIKV cases, an increase of 88 cases since the last CDTR.
    • To date, ZIKV has been confirmed in eight pregnant women.
  • Thailand
    • As of 15 September 2016 and according to media quoting the Ministry of Health, Thailand records about 200 cases since the beginning of the year in 16 provinces.
    • Five provinces are under active control: Bangkok, Chiangmai, Buengkarn, Phetchaboon, Chantaburi.
  • Publication
    • The Lancet published the preliminary findings of a case-control study confirming the association between microcephaly and inutero Zika virus infection.

 

EU/EEA imported cases

  • Since week 45/2015, 19 countries (Austria, Belgium, Czech Republic, Denmark, Finland, France, Ireland, Italy, Luxembourg, Malta, Netherlands, Norway, Portugal, Romania, Slovakia, Slovenia, Spain, Sweden, United Kingdom) have reported 1 614 travel-associated Zika virus infections through The European Surveillance System (TESSy).
  • This corresponds to an increase of 57 cases since the last update.
  • Since week 45/2015, seven EU countries reported 80 Zika cases among pregnant women.
  • Zika virus infections through The European Surveillance System (TESSy).   

 

EU’s Outermost Regions and Territories

  • As of 15 September 2016:
    • Martinique:
      • 36 100 suspected cases have been reported, an increase of 305 since last week. The weekly number of cases is stable.
    • French Guiana:
      • 9 710 suspected cases have been detected, an increase of 86 cases since last week. The weekly number of cases is stable.
    • Guadeloupe:
      • 29 850 suspected cases have been detected, an increase of 380 suspected cases since last week. The weekly number of cases is stable.
    • St Barthélemy:

    • St Martin:
      • 2 265 suspected cases have been detected, an increase of 100 suspected cases since last week. The weekly number of cases is stable.
  • Since February 2016, 12 countries have reported evidence of person-to-person transmission of Zika virus, probably via a sexual route.

 

Update on microcephaly and/or central nervous system (CNS) malformations potentially associated with Zika virus infection

  • As of 8 September 2016, microcephaly and other central nervous system (CNS) malformations associated with Zika virus infection or suggestive of congenital infection have been reported by 20 countries or territories.
  • Brazil reports the highest number of cases.
  • Eighteen countries and territories worldwide have reported an increased incidence of Guillain-Barré syndrome (GBS) and/or laboratory confirmation of a Zika virus infection among GBS cases.
  • In the EU, Spain (2) and Slovenia (1) have reported congenital malformations associated with Zika virus infection after travel in the affected areas.
  • Cases have also been detected in the EU’s Outermost Regions and Territories in Martinique, French Guiana and French Polynesia.

ECDC assessment

  • The spread of the Zika virus epidemic in the Americas is likely to continue as the vectors (Aedes aegypti and Aedes albopictus mosquitoes) are widely distributed there.
  • The likelihood of travel-related cases in the EU is increasing.
  • A detailed risk assessment is available here.
  • As neither treatment nor vaccines are available, prevention is based on personal protection measures.
  • Pregnant women should consider postponing non-essential travel to Zika-affected areas.
