Meeting of the Emergency Committee under the International Health Regulations (2005) concerning Yellow Fever
WHO statement [Editor’s text bolding]
19 May 2016
An Emergency Committee (EC) regarding yellow fever was convened by the Director-General under the International Health Regulations (2005) (IHR 2005) by teleconference on 19 May 2016, from 13:00 to 17:15 Central European Time1.
The following affected States Parties participated in the information session of the meeting: Angola and the Democratic Republic of Congo.
The WHO Secretariat briefed the Committee on the history and impact of the Yellow Fever Initiative, the urban outbreak of yellow fever in Luanda, Angola and its national and international spread to the Democratic Republic of Congo, China and Kenya. The Committee was provided with additional information on the evolving risk of urban yellow fever in Africa and the status of the global stockpile of yellow fever vaccine.
After discussion and deliberation on the information provided, it was the decision of the Committee that the urban yellow fever outbreaks in Angola and the Democratic Republic of the Congo is a serious public health event which warrants intensified national action and enhanced international support. The Committee decided that based on the information provided the event does not at this time constitute a Public Health Emergency of International Concern (PHEIC).
While not considering the event currently to constitute a PHEIC, Members of the Committee strongly emphasized the serious national and international risks posed by urban yellow fever outbreaks and offered technical advice on immediate actions for the consideration of WHO and Member States in the following areas:
:: the acceleration of surveillance, mass vaccination, risk communications, community mobilization, vector control and case management measures in Angola and the Democratic Republic of Congo;
:: the assurance of yellow fever vaccination of all travellers, and especially migrant workers, to and from Angola and Democratic Republic of Congo;
:: the intensification of surveillance and preparedness activities, including verification of yellow fever vaccination in travellers and risk communications, in at-risk countries and countries having land borders with the affected countries.
The Committee also emphasized the need to manage rapidly any new yellow fever importations, thoroughly evaluate ongoing response activities, and quickly expand yellow fever diagnostic and confirmatory capacity. Recognizing the limited international supply of yellow fever vaccines, the Committee also advised the immediate application of the policy of 1 lifetime dose of yellow fever vaccine2 and the rapid evaluation of yellow fever vaccine dose-sparing strategies by the WHO Strategic Advisory Group of Experts on Immunization (SAGE).
Going forward, the Committee agreed with the planned review and revision of the global strategy for preventing urban yellow fever outbreaks in keeping with WHO’s assessment that the risk of such events is increasing.
Based on these views and the currently available information, the Director-General accepted the Committee’s assessment that the current yellow fever situation is serious and of great concern and requires intensified control measures, but does not constitute a PHEIC at this time.
The Director-General urges Member States to enforce the yellow fever vaccination requirement for travellers to and from Angola and the Democratic Republic of the Congo in accordance with the IHR (2005)3
The Director-General thanked the Committee for its thorough advice on priority actions for affected and at-risk countries, and on further yellow fever risk management work for WHO. The Director-General appreciated the concurrence of the Committee to be reconvened if needed.

Yellow Fever – Situation Report – 20 May 2016
Full Report:
http://apps.who.int/iris/bitstream/10665/206548/1/yellowfeversitrep_20May2016_eng.pdf?ua=1
Summary:
Three countries have reported confirmed yellow fever cases imported from Angola: Democratic Republic of The Congo (DRC) (39 cases), Kenya (two cases) and People’s Republic of China (11 cases). This highlights the risk of international spread through non-immunised travellers.
Angola: 2420 suspected cases
As of 19 May 2016, Angola has reported 2420 suspected cases of yellow fever with 298 deaths. Among those cases, 736 have been laboratory confirmed. Despite vaccination campaigns in Luanda, Huambo and Benguela provinces circulation of the virus in some districts persists.
Democratic Republic of The Congo: 44 laboratory confirmed cases
On 22 March 2016, the Ministry of Health of DRC confirmed cases of yellow fever in connection with Angola. The government officially declared the yellow fever outbreak on 23 April. As of 19 May, DRC has reported five probable cases and 44 laboratory confirmed cases: 42 imported from Angola, reported in Kongo central province and Kinshasa and two autochthonous cases in Ndjili, Kinshasa and in Matadi, Kongo Central province. The possibility of locally acquired infections is under investigation for at least eight nonclassified cases in both Kinshasa and Kongo central provinces.
Uganda: 60 suspect cases
In Uganda, the Ministry of Health notified yellow fever cases in Masaka district on 9 April 2016. As of 19 May, 60 suspect cases, of which seven are laboratory confirmed, have been reported from three districts: Masaka, Rukungiri and Kalangala. According to sequencing results, those clusters are not epidemiologically linked to Angola.
The risk of spread
The virus in Angola and DRC is largely concentrated in main cities. The risk of spread and local transmission to other provinces in the three countries remains a serious concern. The risk is high also for potential spread to bordering countries especially those classified as low risks for yellow fever disease (i.e. Namibia, Zambia) where the population, travellers and foreign workers are not vaccinated against yellow fever.
Risk assessment
The outbreak in Angola remains of high concern due to:
:: Persistent local transmission in Luanda despite the fact that more than seven million people have been vaccinated.
:: Local transmission reported in seven highly populated provinces including Luanda.
:: The continued extension of the outbreak to new provinces and new districts.
:: High risk of spread to neighbouring countries. Confirmed cases have already travelled from Angola to DRC, Kenya and People’s Republic of China. As the borders are porous with substantial crossborder social and economic activities, further transmission cannot be excluded. Viraemic patients travelling pose a risk for the establishment of local transmission especially in countries where adequate vectors and susceptible human populations are present.
:: Inadequate surveillance system capable of identifying new foci or areas of cases emerging.
:: High index of suspicion of ongoing transmission in areas hard to reach like Cabinda.

IFRC [to 21 May 2016]

Yellow fever: urgent action needed to prevent international crisis
Geneva, 19 May 2016: Fears are growing that a deadly yellow fever outbreak in Angola – which has already spread to Democratic Republic of the Congo, Kenya and China – will continue to spread internationally without immediate action to prevent it, the International Federation of Red Cross and Red Crescent Societies (IFRC) warned today.
The disease is transmitted by the Aedes aegypti mosquito, which is also responsible for spreading the Zika virus, dengue and chikungunya.
Dr Julie Lyn Hall, the IFRC’s Director of Health, said that limited vaccine supplies, inadequate disease surveillance systems, poor sanitation and everyday cross-border economic and social interaction could turn a national outbreak into a global crisis, if no immediate community-based action is taken.
“Unvaccinated travellers could transform this outbreak into a regional or international crisis if we don’t move quickly to protect vulnerable populations and help communities to reduce their risk of infection,” she said.
Yellow fever has killed 293 people in Angola since the beginning of the outbreak in December 2015, and a further 2,267 people are believed to have been infected. The IFRC released 50,672 Swiss francs from its Disaster Relief Emergency Fund (DREF) on 24 February to support Angolan Red Cross work to support the vaccination of 90,000 people, and conducting community mobilization activities with 60,000 others. A further DREF allocation in support of the Red Cross of the Democratic Republic of the Congo will be issued today…
