Key Updates
:: Countries and territories reporting mosquito-borne Zika virus infections for the first time in the past week:
…Malaysia has reported one locally acquired mosquito-borne Zika infection in the past week. Prior to this, the only evidence of Zika in Malaysia had been a scientific publication that had reported a case of Zika infection identified in Germany in an individual with travel history to Malaysia.

:: 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:

:: Countries and territories reporting Guillain-Barré syndrome (GBS) cases associated with Zika virus infection for the first time in the past week:
The Netherlands reported evidence of person-to-person transmission of Zika virus (probably via a sexual route) for the first time in the past week.

:: Operational updates from the WHO Regional Office for the Americas:
…WHO convened a workshop in Barbados on clinical management of neurological complications.
…A technical mission to Brazil by WHO/PAHO for laboratory assessment and strengthening of Zika diagnostic capacity of State laboratories was completed in August.
…WHO facilitated two meetings in Panama for updating the strategic plan for vector surveillance and control.
…WHO/PAHO carried out missions to Colombia and El Salvador to organize and help launch “Mosquito Awareness Week”.
…In Haiti, WHO and the Ministry of Public Health and Population’s Division of Epidemiology, Laboratory and Research (DELR) held three train-the-trainer workshops on epidemiological surveillance of Zika and its complications in August.

:: The results from the sequencing analysis of Zika virus cases in Singapore indicate that the virus belongs to the Asian lineage and likely evolved from the strain that was previously circulating in Southeast Asia. The recent cases in Singapore do not appear to be the result of imported virus from South America.
:: The 2016 Summer Paralympic Games opened in Rio de Janeiro, Brazil, on 7 September. WHO continues to provide technical support to the Ministry of Health to ensure the 2016 Summer Paralympic Games are as safe as possible for all athletes, volunteers, visitors and residents. There is a low, but not zero, risk of Zika transmission in this setting. All persons should continue to follow guidance on avoiding Zika infection.
:: The fourth meeting of the Emergency Committee was held on 1 September 2016. Having considered the evidence presented, the Committee agreed that due to continuing geographic expansion and considerable gaps in understanding of the virus and its consequences, Zika virus infection and its associated congenital and other neurological disorders continues to be a Public Health Emergency of International Concern.
:: Based on a systematic review of the literature, WHO has concluded that Zika virus infection during pregnancy is a cause of congenital brain abnormalities, including microcephaly, and that Zika virus is a trigger of GBS.
:: Revised guidance on the prevention of sexual transmission was published on 6 September 2016.

Updated guidance on prevention of sexual transmission of Zika virus
6 September 2016 – The interim guidance on prevention of sexual transmission of Zika virus has been updated with new evidence and advice. The primary transmission route of Zika virus is via the Aedes mosquito, however mounting evidence shows that sexual transmission of Zika virus is possible and more common than previously assumed. This is of concern due to an association between the Zika virus and adverse pregnancy outcomes.
