The Committee concurred with the international scientific consensus, reached since the Committee last met, that Zika virus is a cause of microcephaly and GBS, and, consequently, that Zika virus infection and its associated congenital and other neurological disorders is a Public Health Emergency of International Concern (PHEIC).
The Committee restated the advice it provided to the Director-General in its 2nd meeting in the areas of public health research on microcephaly, other neurological disorders and Zika virus, surveillance, vector control, risk communications, clinical care, travel measures, and research and product development.
The Committee noted that mass gatherings, such as the Olympic and Paralympic Games, can bring together substantial numbers of susceptible individuals, and can pose a risk to the individuals themselves, can result in the amplification of transmission and can, potentially, contribute to the international spread of a communicable disease depending on its epidemiology, the risk factors present and the mitigation strategies that are in place.
In the context of Zika virus, the Committee noted that the individual risks in areas of transmission are the same whether or not a mass gathering is conducted, and can be minimized by good public health measures.

委员会重申了在国际旅行者预防感染问题上向总干事提出的以下意见并做了更新：
The Committee reaffirmed and updated its advice to the Director-General on the prevention of infection in international travellers as follows:
6276
应当建议孕妇不要前往正发生寨卡病毒传播的地区旅行。
Pregnant women should be advised not to travel to areas of ongoing Zika virus outbreaks; pregnant women whose sexual partners live in or travel to areas with Zika virus outbreaks should ensure safe sexual practices or abstain from sex for the duration of their pregnancy,
Travellers to areas with Zika virus outbreaks should be provided with up to date advice on potential risks and appropriate measures to reduce the possibility of exposure through mosquito bites and sexual transmission and, upon return, should take appropriate measures, including practicing safer sex, to reduce the risk of onward transmission,
6278
世界卫生组织应当随着与寨卡病毒相关危险的性质和持续时间的演变情况定期对旅行指导做出更新。
The World Health Organization should regularly update its guidance on travel with evolving information on the nature and duration of risks associated with Zika virus infection.
Based on the existing evidence from the current Zika virus outbreak, it is known that this virus can spread internationally and establish new transmission chains in areas where the vector is present.
Focusing on the potential risks associated with the Olympic and Paralympic Games, the Committee reviewed information provided by Brazil and Advisors specializing in arboviruses, the international spread of infectious diseases, travel medicine, mass gatherings and bioethics.
