WHO statement on the third meeting of the International Health Regulations (2005) (IHR(2005)) Emergency Committee on Zika virus and observed increase in neurological disorders and neonatal malformations
WHO statement
14 June 2016
The third meeting of the Emergency Committee (EC) convened by the Director-General under the International Health Regulations (2005) (IHR 2005) regarding microcephaly, other neurological disorders and Zika virus was held by teleconference on 14 June 2016, from 13:00 to 17:15 Central European Time. In addition to providing views to the Director-General on whether the event continued to constitute a Public Health Emergency of International Concern (PHEIC), the Committee was asked to consider the potential risks of Zika transmission for mass gatherings, including the Olympic and Paralympic Games scheduled for August and September 2016, respectively, in Rio de Janeiro, Brazil.
The Committee was briefed on the implementation of the Temporary Recommendations issued by the Director-General on 8 March 2016 and updated on the epidemiology and association of Zika virus infection, microcephaly and Guillain-Barré Syndrome (GBS) since that time. The following States Parties provided information on microcephaly, GBS and other neurological disorders occurring in the presence of Zika virus transmission: Brazil, Cabo Verde, Colombia, France, and the United States of America. Advisors to the Committee provided further information on the potential risks of Zika virus transmission associated with mass gatherings and the upcoming Olympic and Paralympic Games, and the Committee thoroughly reviewed the range of public perspectives, opinions and concerns that have recently been aired on this subject.
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. The Committee reaffirmed and updated its advice to the Director-General on the prevention of infection in international travellers as follows:
:: 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,
:: 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. The Committee concluded that there is a very low risk of further international spread of Zika virus as a result of the Olympic and Paralympic Games as Brazil will be hosting the Games during the Brazilian winter when the intensity of autochthonous transmission of arboviruses, such as dengue and Zika viruses, will be minimal and is intensifying vector-control measures in and around the venues for the Games which should further reduce the risk of transmission.
The Committee reaffirmed its previous advice that there should be no general restrictions on travel and trade with countries, areas and/or territories with Zika virus transmission, including the cities in Brazil that will be hosting the Olympic and Paralympic Games. The Committee provided additional advice to the Director-General on mass gatherings and the Olympic and Paralympic Games as follows:
:: Countries, communities and organizations that are convening mass gatherings in areas affected by Zika virus outbreaks should undertake a risk assessment prior to the event and increase measures to reduce the risk of exposure to Zika virus,
:: Brazil should continue its work to intensify vector control measures in and around the cities and venues hosting Olympic and Paralympic Games events, make the nature and impact of those measures publicly available, enhance surveillance for Zika virus circulation and the mosquito vector in the cities hosting the events and publish that information in a timely manner, and ensure the availability of sufficient insect repellent and condoms for athletes and visitors,
:: Countries with travellers to and from the Olympic and Paralympic Games should ensure that those travellers are fully informed on the risks of Zika virus infection, the personal protective measures that should be taken to reduce those risks, and the action that they should take if they suspect they have been infected. Countries should also establish protocols for managing returning travellers with Zika virus infection based on WHO guidance,
:: Countries should act in accordance with guidance from the World Health Organization on mass gatherings in the context of Zika virus outbreaks, which will be updated as further information becomes available on the risks associated with Zika virus infection and factors affecting national and international spread.
Based on this advice the Director-General declared the continuation of the Public Health Emergency of International Concern (PHEIC). The Director-General reissued the Temporary Recommendations from the 2nd meeting of the Committee, endorsed the additional advice from the Committee’s 3rd meeting, and issued them as Temporary Recommendations under the IHR (2005). The Director-General thanked the Committee Members and Advisors for their advice.

Zika virus outbreak global response – Updated 17 June 2016
WHO/PAHO and partners have set out their strategic response to Zika which will place a greater focus on preventing and managing medical complications caused by Zika virus infection. To date, US$121.9 million are necessary to effectively implement the Zika Strategic Response Plan, July 2016 to December 2017.
The revised Zika Strategic Response Plan includes a greater focus on preventing and managing medical complications caused by Zika virus infection and expanding health systems’ capacities for that purpose. Risk communication targeting pregnant women, their partners, households and communities will be central to prevention efforts to ensure they have the information they need to protect themselves.
Other elements include integrated vector management, sexual and reproductive health counselling as well as health education and care within the social and legal contexts of each country where Zika virus is being transmitted.
The plan highlights several specific characteristics of the Zika outbreak that require a collaborative, global response and support. These include:
:: the potential for further international spread of Zika virus given the wide distribution of Aedes mosquitoes that are capable of transmitting Zika virus,
:: the lack of population immunity in areas where Zika virus is circulating for the first time and which allows the disease to spread quickly,
:: the absence of vaccines, specific treatments and rapid diagnostic tests, and
:: inequalities in access to sanitation, information and health services in affected areas.
