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.

Argentinian researchers develop plastic ovitrap to monitor, control Aedes aegypti mosquito

Argentinian researchers from the Centro de Investigaciones de Plagas e Insecticidas have developed a new trap that can be used to effectively monitor and control the Aedes aegypti mosquito, which is the primary transmitter of Zika, dengue, chikungunya, and yellow fever. The trap is described in the Journal of Medical Entomology. [More]

Tackling Zika virus: Challenges ahead

Tackling Zika virus: Challenges ahead

Health officials, drug companies, governments and the public are scrambling to understand and combat the Zika virus. The virus was first identified almost 70 years ago, but little is known about it. And now, officials suspect it could be related to a rise in microcephaly cases in affected countries. [More]

UF study shows effective way to control damaging health impacts of mosquito-borne diseases

UF study shows effective way to control damaging health impacts of mosquito-borne diseases

A common toxin used to kill yellow fever mosquito larvae - the most prevalent transmitter of dengue, chikungunya and zika viruses - is highly effective. While there are some fitness advantages to surviving adults, this is still an effective way to control the damaging health impacts of these mosquito-borne diseases, a new University of Florida study shows.
