2 Acknwledgements This guidance was prepared by WHO in cllabratin with experts frm WHO and with the Internatinal Civil Aviatin Organizatin, the Internatinal Air Transprt Assciatin and the US Centers fr Disease Cntrl and Preventin, Atlanta, USA. 2

3 I. Intrductin As the Ebla virus disease (EVD) cntinues t claim lives and put pressure n health systems in West Africa, its transmissin acrss brders has prmpted a need t manage suspected cases at Pints f Entry (PE).1 This shuld be cnducted accrding t WHO recmmendatins and risk assessments, and adapted accrding t the unique characteristics f each PE. It shuld als be cnsistent with internatinal best practices and standard peratinal prcedures (e.g. fr air pints f entry by the Internatinal Civil Aviatin Organizatin and Internatinal Air Transprt Assciatin). This interim guidance dcument is intended fr Natinal Fcal Pints fr the Internatinal Health Regulatins (IHR)(2005) 1, PE public health authrities, PE peratrs, cnveyance peratrs, crew members and ther stakehlders invlved in the management f Public health event It shuld be used as a reference and in cnjunctin with WHO publicatins n cntingency planning at PE, lcal established capacities and emergency plans. It is recmmended that the cntents f this dcument be adapted t the present situatin, lcal requirements and cmmn practice. Public health emergency plans and standard peratinal prcedures shuld be in place at designated PEs, in accrdance with internatinal best practices, agreements, and the IHR. The aim is t prvide: early detectin f ptentially infected persns; t assist in implementing WHO recmmendatins related t Ebla management; and t prevent the internatinal spread f the disease while allwing PE authrities t avid unnecessary restrictins and delays. T mitigate the risk f infectius travellers barding aircraft and ther mdes f transprtatin, and minimize the interference t PE peratins, the fllwing measures shuld be established. States with Ebla virus disease (EVD) transmissin: Cnduct exit screening f all persns at internatinal airprts, seaprts and majr land crssings fr unexplained febrile illness cnsistent with ptential Ebla infectin. At a minimum, the exit screening shuld cnsist f a questinnaire, a temperature measurement and, if there is a fever, an assessment f the risk that the fever is caused by EVD. Fr all pints f entry: Ensure a public health emergency cntingency plan is in place at each designated PE. Fr internatinal airprts, the aerdrme emergency plan shuld include a public health cmpnent, in accrdance with Internatinal Civil Aviatin Organizatin Health related requirements. Allcate a place at PE fr health assessments, in the event f suspected illness detected in a traveller. Establish standard perating prcedures fr refer ill travellers t designated hspitals, including the identificatin f adequate ambulance services. 1 PE- Pints f Entry: a passage fr internatinal entry r exit f travellers, baggage, carg, cntainers, cnveyances, gds and pstal parcels as well as agencies and areas prviding services t them n entry r exit. Frm the Internatinal Health Regulatins (2005). 3

4 Ensure a sufficient number f trained staff, with apprpriate and sufficient Persnal Prtective Equipment (PPE) and disinfectant. Raise awareness amng cnveyance peratrs f the need t immediately ntify PE health authrities prir t arrival f any suspected cases. Ensure that passenger lcatr frms are n bard flights and at the airprt, and that airprt grund staff and flight crew are trained in managing EVD and envirnmental cntaminants. Maintain effective and rapid cmmunicatin between PE health authrities and the natinal health surveillance system. Prmptly establish lines f cmmunicatin between public health and transprt sectr fficials, e.g. representatives f the natinal civil aviatin authrity, airprt peratrs and aircraft peratrs. Raise awareness f EVD and disseminate infrmatin amng all relevant stakehlders at PE. 4

5 II. Management f events During travel, a ptential case may be detected at varius pints. The apprpriate respnse depends n the nature f the expsure, the status f glbal alerts and awareness f varius parties. (Figure 1) Figure 1. Ptential pints f public health hazard detectin r ntificatin. Preliminary standard respnse at PE: recmmended actins t be taken at specified stages f travel (see figure 1) Steps Questins Surce f infrmatin Recmmendatins fr actin Detectin at PE at departure Des the passenger appear t be unwell? Are the symptms cnsistent with suspected EVD? Symptms may include: fever, weakness, muscle pain, headache, sre thrat, vmiting, diarrhea, rash, r bleeding If the cuntry is unaffected by Ebla: - Has the passenger had previus cntact with anyne suspected r cnfirmed t have Ebla? - Des the passenger s recent travel histry include a cuntry where there is an EVD utbreak? If Yes t any f the abve questins, please refer t recmmendatins fr Ebla case management at PE f rigin in cuntries with EVD transmissin. Health authrity at PE and ther PE staff (custms, brder security, grund staff, etc.) The PE health authrity shuld cnsider making prir arrangements in crdinatin with the PE peratr, cnveyance peratr, ther stakehlders at PE, and the natinal health authrity fr early detectin and t prevent ill persns with symptms f EVD frm disembarking prvide infrmatin t travellers at pints f entry n the ptential risk f EVD - prvide reginal r natinal public health cntact infrmatin - ensure any persn with an illness cnsistent with EVD is nt permitted t travel unless the travel is part f an apprpriate medical evacuatin, if PE is at the cuntries with EVD transmissin - identify interpreters if needed. If the traveller has recently travelled t an EVD-affected area, and is shwing symptms indicative f EVD, the PE health authrity shuld cnsider the fllwing actins: - activating the public health emergency plan at the PE - arranging medical examinatin - arranging transprt f suspected cases t designated hspitals - arranging cllectin f clinical specimens r envirnmental specimens 5

6 - arranging transprt and delivery f clinical specimens t an apprpriate labratry - strengthening surveillance and public health measures at PE - maintaining effective and rapid cmmunicatin between PE health authrities and the natinal health surveillance system. At the PE f a cuntry with EVD transmissin, exit screening f all persns shuld be cnducted at internatinal airprts, seaprts and majr land crssings, fr unexplained febrile illness cnsistent with ptential EVD infectin. At a minimum, the exit screening shuld cnsist f a questinnaire, a temperature measurement and, if there is a fever, an assessment f the risk that the fever is caused by EVD. Ensure persnal prtective equipment (PPE) and hand hygiene practice and prducts are available (alchl-based hand-rub slutins, running water, sap, and single-use twels). Staff cnducting exit screening shuld be trained in the crrect use f PPE and infectin cntrl in handling suspected cases. Additinal actins fr travellers with suspected EVD at PE, prir t embarking (either at the cunter, in the passenger lunge prir t barding r at the time f barding) Is the traveller/crew symptmatic (number f affected passengers/crew)? What was the time/date f illness nset? Des travel histry imply cntact with anyne suspected f having EVD, r with a histry f previus travel in EVD- affected areas? Has any death ccurred? What is the traveller s health status? (Symptmatic? High risk f EVD expsure?) Cnveyance peratrs, agents, staff, passengers, PE persns, r ther authrities Fr PE f cuntries with EVD transmissin, any persn with an illness cnsistent with EVD shuld nt be allwed t travel unless the travel is part f an apprpriate medical evacuatin Air Travel/Aircraft If traveller/crew member displays symptms related t EVD r is cnsidered t be in clse cntact with EVD (r ther cmmunicable diseases) - Medical clearance is required by the airline - If a traveller des nt present medical clearance t the airline and refuses t delay his/her travel, the airline may exercise its right t refuse barding, in the case f air travel - Ensure Public Health Passenger Lcatr Frms (PLFs) see are available n bard the aircraft and/r at the destinatin PE.
