Since Dec. 5, 2015, Luanda, Angola, has been contending with a yellow fever outbreak.
On Mar. 21, the World Health Organization (WHO) provided information about the progress of the fever, stating that only two of the 18 provinces in Angola are yellow fever-free.
Angola has seen 1,132 cases of yellow fever and 168 deaths since the outbreak began. Luanda is the confirmed source of the outbreak and has the most amount of suspected cases at 818 -- although other provinces may be catching up soon.
A WHO-supported task force has been sent to Angola to combat the Grade 2 emergency with vaccines and medical treatment as reported by the Emergency Response Framework (ERF).
The WHO also continually tracks the fever to detect its infection patterns and where it may head next. The organization is particularly concerned that yellow fever will be transmitted across the border and become an international problem; there have already been rumors of its transmission to China, Kenya and the Democratic Republic of Congo.
Consequently, there are more stringent vaccination regulations for those attempting to enter Asia, specifically from Africa or Latin America. Still, the WHO declares that travel to Angola is safe as long as people attempt to prevent mosquito bites and are vaccinated against yellow fever.
