Yellow Fever News and Research RSS Feed - Yellow Fever News and Research

Yellow fever virus, a flavivirus, is transmitted to humans through the bite of infected mosquitoes. Illness ranges in severity from a self-limited febrile illness to severe hepatitis and hemorrhagic fever. Yellow fever disease is diagnosed based on symptoms, physical findings, laboratory testing, and the possibility of exposure to infected mosquitoes. There is no specific treatment for yellow fever; care is based on symptoms. Steps to prevent yellow fever include use of insect repellent, protective clothing, and vaccination. Yellow fever occurs in tropical regions of Africa and in parts of South America. Yellow fever is a very rare cause of illness in U.S. travelers. The last epidemic of yellow fever in North America occurred in New Orleans in 1905.
Research reveals how Zika virus arrests fetal brain development in pigtail macaque

Scientists reveal new structural insights on key protein from mosquitoes linked to spread of Zika

Scientists reveal new structural insights on key protein from mosquitoes linked to spread of Zika

As health departments around the U.S. boost efforts to combat Zika, scientists are working on new ways to kill the mosquitoes that carry the virus. One approach involves understanding the molecular mechanisms that keep the bugs alive so we can then undermine them. [More]

Large emergency vaccination campaigns to curb yellow fever outbreak in Angola, Democratic Republic of Congo

One of the largest emergency vaccination campaigns ever attempted in Africa will start in Angola and the Democratic Republic of Congo this week as WHO and partners work to curb a yellow fever outbreak that has killed more than 400 people and sickened thousands more. [More]
New odour-baited traps offer effective and safe solution to fight against malaria mosquito

New odour-baited traps offer effective and safe solution to fight against malaria mosquito

The use of a newly-developed mosquito trap incorporating human odour has resulted in a 70% decline in the population of the most significant malaria mosquito on the Kenyan island of Rusinga. [More]
Scientists modeling new control mechanism to combat Zika-infecting mosquitoes

Scientists modeling new control mechanism to combat Zika-infecting mosquitoes

The images are heartbreaking: thousands of infants born with small, misshapen heads, the result of a rare neurological disorder, called microcephaly, which can cause a myriad of intellectual and developmental disabilities. The culprit? Zika, a mosquito-borne virus that has swept through many parts of South America and more recently surfaced in Florida. [More]
New study provides projections for Zika outbreaks in the Americas through January 2017

New study provides projections for Zika outbreaks in the Americas through January 2017

With the report from Florida Gov. Rick Scott on Monday that 14 people in the state have been infected with the Zika virus most likely through mosquito transmission, the concern about out­breaks in the U.S. has intensified. [More]
Scientists seeking blood donations from people exposed to arboviruses for dengue, Zika vaccine research

Scientists seeking blood donations from people exposed to arboviruses for dengue, Zika vaccine research

Researchers at the University of North Carolina School of Medicine are conducting studies that utilize blood donations from individuals who have been diagnosed with or potentially exposed to mosquito-borne viruses as part of ongoing dengue and Zika research and vaccine development. [More]
WHO supports deployment of mobile lab for fast-tracking diagnosis of yellow fever

WHO supports deployment of mobile lab for fast-tracking diagnosis of yellow fever

“Treating a yellow fever patient is reliant on having the right diagnosis. This is dependent on having the necessary laboratory capacity to quickly identify the disease,” says Dr Pierre Formenty, an expert in haemorrhagic fevers at WHO and Manager of the Emerging Dangerous Pathogens Laboratory Network.
