List of countries and territories reporting mosquito-borne Zika virus transmission (Table 1.)
- Countries and territories reporting mosquito-borne Zika virus infections for the first time in the past week:
- Countries and territories reporting microcephaly and other central nervous system (CNS) malformations potentially associated with Zika virus infection for the first time in the past week:
- Bolivia, Trinidad and Tobago, and Viet Nam
- Countries and territories reporting Guillain-Barré syndrome (GBS) cases associated with Zika virus infection for the first time in the past week:
- The Ministry of Health and Sport of Myanmar reported a confirmed case of Zika virus. The case is under investigation as to determine if this is an autochthonous (locally-acquired) or imported case.
- Overall, the global risk assessment has not changed since last week.
- Viet Nam is the second county in South-East Asia to report microcephaly cases potentially linked with Zika virus. This follows the 2 microcephaly cases reported in Thailand in the 6 October Zika situation report. Similar to the cases reported in Thailand, genetic sequencing of the virus was not possible therefore it is not known whether the mother was infected with a virus related to the same lineage as previously isolated in South-East Asia, or if there has instead been transmission of a virus imported from another location. The mother of the baby with microcephaly reported in Viet Nam had no history of travel outside of the country. To date, there have been no imported Zika virus cases reported in Viet Nam.
