Clinical Features and Diagnosis of Yellow Fever
Clinical considerations Yellow fever virus is a mosquito-borne flavivirus endemic in tropical areas of Africa and South America. Although most infections are asymptomatic, clinical disease ranges from a mild febrile illness to severe disease with hepatitis and hemorrhagic manifestations. Preliminary diagnosis of yellow fever is based on the patient's clinical features, vaccination status ...
Yellow fever: Epidemiology, clinical manifestations, and ...
Yellow fever is a mosquito-borne viral hemorrhagic febrile disease with a high case-fatality rate. Clinical manifestations include hepatic dysfunction, renal failure, coagulopathy, and shock. Travelers to tropical regions of South America and sub-Saharan Africa where the disease is endemic are at risk for acquisition of infection and require ...
Yellow Fever Clinical Presentation
The clinical presentation is divided into 3 stages: the period of infection, the period of remission, and, if it progresses, the period of intoxication. Period of infection. More serious illness develops in 15% of cases and presents with the abrupt onset of general malaise, fever, chills, headache, lower back pain, nausea, and dizziness.
Yellow Fever
Yellow fever is a mosquito-borne viral illness found in tropical and subtropical areas in South America and Africa. Transmission is primarily via Aedes and Haemagogus species of mosquito. It can present with varying clinical features ranging from a self-limited, mild febrile illness to severe hemorrhage and liver disease. The "yellow" comes from jaundice that affects some patients with ...
Yellow Fever: Symptoms, Diagnosis, and Treatment
People with severe symptoms of yellow fever infection should be hospitalized for close observation and supportive care. If after returning from travel you have symptoms of yellow fever, protect yourself from mosquito bites for up to 5 days after symptoms begin.

WHO fact sheet about yellow fever, an acute viral haemorrhagic disease transmitted by infected mosquitoes. It provides key facts and information on signs and symptoms, populations at risk, transmission, treatment, prevention, WHO response.
About Yellow Fever
Key points Yellow fever virus is transmitted to people primarily through the bite of infected mosquitoes. Illness ranges from a fever with aches to severe liver disease with bleeding and yellowing skin and eyes. A vaccine is available for at risk travelers. You can also reduce your risk by avoiding mosquito bites.

Yellow fever
A viral haemorrhagic fever caused by a flavivirus transmitted by the Aedes or Haemagogus mosquito. It is endemic in South America, the Caribbean, and Africa, and has been resurging in the last 2 decades. [1] [2] The clinical disease is variable, ranging from a non-specific viral illness to haemorrhagic fever and death. WHO: yellow fever.
Yellow Fever: Practice Essentials, Background, Etiology
Yellow fever is a mosquito-borne disease that is endemic to tropical South America and Sub-Saharan Africa (see the image below). Its presentation can range from asymptomatic illness to acute-onset viral hepatitis and hemorrhagic fever. [ 1, 2] This female Aedes aegypti mosquito is shown after landing on a human host.
Yellow fever
Yellow fever is an epidemic-prone vector-borne vaccine preventable viral disease that is transmitted to humans by the bites of infected mosquitos. In some of the unvaccinated individuals, the virus can cause severe illness including jaundice and bleeding (severe cases).
Yellow Fever: A Reemerging Threat
The phases of yellow fever, indicating the clinical symptoms in the periods of infection, remission, and intoxication, alongside the pathogenesis of infection. In approximately 20% of patients, illness reappears in a more severe form, the "period of intoxication," with high fever, vomiting, epigastric pain, prostration, and dehydration.
Pediatric Yellow Fever Clinical Presentation
The clinical spectrum of yellow fever (YF) ranges from a minimally symptomatic flulike illness to a catastrophic illness complicated by hemorrhage and organ failure (primarily the liver and kidney). It develops in a number of distinct phases (not all of which invariably occur). The incubation period typically lasts 3-6 days.
Yellow Fever
Typically, yellow fever is suspected on the basis of clinical presentation and confirmed later, since definitive diagnosis requires testing available only in specialized laboratories.
Yellow Fever: Origin, Epidemiology, Preventive Strategies and Future
Symptoms include fever, headache, jaundice, muscle pain, nausea, vomiting, and fatigue. Such variety in the clinical spectrum makes YF diagnosis difficult. In those patients presenting a severe infection, hemorrhagic fever can develop leading to the death of the infected subjects.

INTRODUCTION Yellow fever is a mosquito-borne viral hemorrhagic fever with a high case-fatality rate. Clinical manifestations include hepatic dysfunction, renal failure, coagulopathy, and shock. Travelers to tropical regions of South America and sub-Saharan Africa where the disease is endemic are at risk for acquisition of infection and require immunization.
Yellow Fever: Epidemiology and Prevention
The presentation of yellow fever disease ranges from subclinical infection to systemic disease including fever, jaundice, hemorrhage, and renal failure. Differences in virus strains, as well as incompletely understood host immune factors, are likely responsible for the range of clinical symptoms.

Yellow fever: an update
In these patients, the clinical presentation and liver histopathology resembled that caused by wild-type yellow fever virus. There was no evidence for immune suppression or other known risk factors for enhanced infection.
Yellow Fever
Yellow fever is an infectious disease caused by yellow fever virus (YFV), Flavivirus genus of the Flaviviridae family, which is endemic in South America and Africa, and periodically has caused limited outbreaks or large epidemics in the endemic regions.
Safety and immunogenicity of a next-generation live-attenuated yellow
The yellow fever microneutralisation assay (developed by Sanofi) employed in this study was previously shown to have suitable precision, accuracy, and specificity for the detection and quantification of yellow fever NAb titres in human clinical serum samples (unpublished).
Yellow fever in the diagnostics laboratory
YEL-AVD clinical presentation is similar to wild-type YF disease with nonspecific initial symptoms, including fever, headache, malaise, myalgia, arthralgia, nausea, vomiting, and diarrhea, starting 2-8 days after vaccination.
Safety and immunogenicity of a next-generation live-attenuated yellow
A next-generation live-attenuated yellow fever vaccine candidate (vYF), produced in a Vero cell line has shown similar immunogenicity to licensed yellow fever vaccines in preclinical studies. In this study, we aimed to report the safety and immunogenicity of vYF in human clinical trial participants.
The promising prospects of a new yellow fever vaccine
In this issue of The Lancet Infectious Diseases, Kayvon Modjarrad and colleagues1 report on the safety and immunogenicity of a next-generation life-attenuated Vero cell line derived yellow fever vaccine, vYF-247. The prospect of a new yellow fever vaccine is good news, and the results of this first in-human trial are highly promising. But the bar is set high if bioequivalence with the current ...
