Additional health measures under the InternationalHealth Regulations (2005)
κ Unjustified restrictions of travel or trade during outbreaks can have a massiveeconomic impact on affected countries.
κ Article 43 of the IHR: if States Parties implement health measures that restrictinternational traffic, they are obliged to report to WHO the rationale and publichealth justification within 48h.
κ WHO is required to share such information with other States and may askStates to reconsider the measures.
κ If measures are unjustified, WHO may escalate to national authorities, butthere is no enforcement mechanism under the IHR to ensure compliance withrequirements related to unjustified measures, only peer pressure/moralobligation.

Impact of additional health measuresImpact of additional health measures
κ Harm national economies of affected countries
κ Discourage countries from openly reporting outbreaks
κ Do not delay much the international spread
κ Create barriers for the response
κ Impact travellers at personal level

κ WHO advice for international travellers:– Published on 3 October - aligned with ECDC
and CDC advisories– Risk of international spread considered very
low– WHO does not recommend any restrictions to
travel and trade
κ Emergency Committee (EC) under the IHR:– EC not called: based on the Secretariat's
assessment, the event did not constitute a"public health emergency of internationalconcern"
κ Exit screening protocol at internationalairport in Madagascar
– Early October by national authorities– WHO and GOARN partners (CDC, INVS)
further strengthened the protocol
κ WHO provided support for preparednessand readiness for neighbouring countriesand territories

κ WHO actively tracking health measures related to international traffic– Media signals– Regular communication with ICAO, IATA, IMO (International Maritime Organization)– Information included in sitreps for transparency and peer-pressure
κ Preparedness in neighbouring countries– Draft Guidance note on IHR provisions related to international traffics shared with neighbouring countries– Increase awareness, preposition equipment's and supplies, contingency planning, and technical assistance
κ AirSeyechelles, stopped the flights to Madagascar, at the request of Public Health Authority,as of 8 October:
– Rationale sent to WHO 3 weeks after the implementation of the measure• only suspension of travel considered (protection of the population and limited capacity of response)• other measures including isolation of passengers coming from Madagascar not addressed
– WHO provided technical support to Seychelles for epidemiological surveillance and risk communication

Guidelines on effectiveness and impact of travel andtrade restrictions
Guidelines on effectiveness and impact of travel andtrade restrictions
κ Following WHO guidelines review process
κ Internal Steering group
κ External guidelines development group
κ Develop PICO questions, identify or commission systematic review
κ Formulate recommendations, taking into account benefits and harms,values and preferences
International Health Regulations10 |
Elements of the PICO questionsElements of the PICO questions
κ Target population for the intervention: international travellers, local population (in bothaffected and receiving countries)
κ Interventions: exit screening, entry screening, quarantine, closure of borders (visarefusal, denial of entry for more than 24h), trade bans
κ Comparison: absence of the intervention
κ Outcomes: detection of cases at border/prevention of international spread/ delay ofinternational spread; economic impact, impact on tourism and trade.
κ Events: contaminated goods, Cholera, Ebola (and other viral haemorrhagic fevers), Food-borne diseases, Influenza, Meningitis, MERS, Pneumonic Plague, Rift Valley Fever, SARS,Yellow fever, Zika.
κ Out of scope for these guidelines: interventions governed by OIE standards

Objectives
κ to review the effectiveness of travel or traderestrictions on the prevention of internationalspread of diseases.
κ to develop specific recommendations on therelevance and justification of public healthmeasures for:
– preventing the exportation/importation ofdiseases via movement of people, vectors orgoods
– managing the risk perception of populationsin non-affected areas, preventing thuseconomic losses and political concerns.
Deliverablesκ repository of evidence-base on the
effectiveness of travel and trade restrictions onthe prevention of international spread ofdiseases and their economic and trade impact(focus on VHFs, selected air-borne and food-borne diseases)
κ evidence-based guidance on the relevance andjustification of public health measures atborders during outbreaks
κ research agenda on the benefits and harms oftravel and trade restrictions during outbreaks(including the role of modelling to informdecision-making on travel and traderestrictions)
