Editor’s Note:
Without any specific advisory or context information, WHO posted a report on a new ‘Yellow Fever” page titled: “Situation Report – Zika Virus Disease, Yellow Fever, Ebola Virus Disease.” The report appears to revive the previously discontinued Ebola Situation Report, partially duplicate the Zika Situation Report (which still appears as a free-standing report as below), and includes a “Risk Assessment” statement for each disease area:

Zika Virus Disease
Risk assessment
Overall, the global risk assessment has not changed since April 21. Zika virus continues to spread geographically to areas where competent vectors are present. Although a decline in cases of Zika infection has been reported in some countries, or in some parts of countries, vigilance needs to remain high. At this stage, based on the evidence available, WHO does not see an overall decline in the outbreak.

Yellow Fever
Risk assessment
:: The outbreak in Angola remains of high concern due to:
:: Persistent local transmission in Luanda despite that fact that almost six million people have been vaccinated.
:: High risk of spread to neighbouring countries. Confirmed cases have already travelled from Angola to China, DRC and Kenya.
:: A field investigation concluded there is a high risk of local transmission of Yellow Fever in DRC.

Ebola Virus Disease
Risk assessment:
Although all of the previous outbreaks have been stopped, the performance indicators suggest that the three countries still have variable capacity to prevent (care for survivors), detect (epidemiological and laboratory surveillance) and respond to new outbreaks (Table 7). The risk of additional outbreaks remains.

Yellow fever vaccination essential for Angola, WHO reminds travellers
WHO News release
26 APRIL 2016 | GENEVA – As efforts to bring an outbreak of yellow fever in Angola under control continue, WHO is reminding all travellers to the country that they are required to receive the yellow fever vaccination and to have a valid certificate of vaccination to prove that they are protected from the disease and to prevent its further spread.

Since the outbreak in Angola began in December 2015, 1 975 suspected cases of yellow fever (618 laboratory confirmed) and 258 deaths have been reported, the majority of them in the capital, Luanda, and in 2 other provinces. Amid concerns that the virus will spread to other urban areas and to neighbouring countries, a large-scale vaccination campaign was launched in February 2016 and has so far reached almost 7 million people.

“Cases of yellow fever linked to this outbreak have been detected in other countries of Africa and Asia. We are particularly concerned that large urban areas are at risk and we strongly urge all travellers to Angola to ensure they are vaccinated against yellow fever and carry a valid certificate,” said Dr Margaret Chan, WHO Director-General…
