Sudan: Third phase in yellow fever vaccination campaign in Darfur to commence this weekend
The Darfur yellow fever outbreak has affected more than 840 people, killing 171 people in 35 localities in Darfur since the outbreak began during the last months of 2012. Thanks to the international donor community, two phases of a mass vaccination campaign have been completed from late November through early January 2013, which covered some 3 million-plus people.
The third phase of the yellow fever vaccination campaign is scheduled to begin Jan . 26 and is expected to cover more than 2 million more people at risk, according to a World Health Organization in Sudan news release Jan. 23.
According to the WHO, the operational requirements as well as costs of vaccines for Phases I and 2 of the emergency vaccination campaign were supported by the European Commission Directorate General for Humanitarian Aid and Civil Protection (ECHO), the Central Emergency Response Fund (CERF), and the Government of Sweden.
The United Kingdom’s Department for International Development (DFID) and the United States Agency for International Development (USAID) are supporting phase 3 of the campaign.
Yellow fever is an acute viral hemorrhagic disease transmitted by infected mosquitoes. The “yellow” in the name refers to the jaundice that affects some patients. The yellow fever virus is an arbovirus of the flavivirus genus, and the mosquito is the primary vector. It carries the virus from one host to another, primarily between monkeys, from monkeys to humans, and from person-to-person.
Once contracted, the virus incubates in the body for 3 to 6 days, followed by infection that can occur in one or two phases. The first acute phase usually causes fever, muscle pain with prominent backache, headache, shivers, loss of appetite, and nausea or vomiting. Most patients improve and their symptoms disappear after 3 to 4 days.
The current outbreak in Darfur has seen a 20 percent case-fatality rate.
