Safety of the yellow fever vaccine in people living with HIV: a longitudinal study exploring post-vaccination viremia and hematological and liver kinetics
CONCLUSIONS: 17DD was safe and well-tolerated in PLWH with CD4 ≥ 200 cells/µL. Post-vaccination viremia was more frequent in PLWH than in controls. Transient and self-limited decreases in lymphocytes and neutrophils occurred early after vaccination. 17DD viremia was associated with lower lymphocytes and platelets nadir after vaccination. We did not observe elevations in ALT after 17DD vaccination.PMID:38341187 | DOI:10.1016/j.bjid.2024.103719 (Source: Braz J Infect Dis)

Diurnal variation of the chemical composition and insecticidal activity of essential oils of three aromatic plants of the Togolese flora against the dengue vector Aedesaegypti
Exp Parasitol. 2024 Feb 5:108708. doi: 10.1016/j.exppara.2024.108708. Online ahead of print.ABSTRACTThe present reported work deals with the ability of Togolese plants' essential oils (EOs) to act as repellents for Aedes aegypti mosquitoes in order to use them as personal protective requirements or actions against mosquito bites and therefore to drastically reduce the risk of contracting dengue or yellow fever. EOs studied here were extracted from dry leaves of Ageratum conyzoides L., Eucalyptus citriodora Hook, and Lantana camara Linn, three plants that were collected at different daytimes (7 a.m., 1 p.m., and 7 p.m.) at ...

Viruses, Vol. 16, Pages 242: The Role of Noncoding RNA in the Transmission and Pathogenicity of Flaviviruses
ong Cheng
Noncoding RNAs (ncRNAs) constitute a class of RNA molecules that lack protein-coding capacity. ncRNAs frequently modulate gene expression through specific interactions with target proteins or messenger RNAs, thereby playing integral roles in a wide array of cellular processes. The Flavivirus genus comprises several significant members, such as dengue virus (DENV), Zika virus (ZIKV), and yellow fever virus (YFV), which have caused global outbreaks, resulting in high morbidity and mortality in human populations. The life cycle of arthropod-borne flaviviruses encompasses their transmission between hematophagous ...

Vaccination against yellow fever in fractionated doses without a previous skin test and egg anaphylaxis
Yellow fever is a public health problem with a high morbimortality. The vaccine against yellow fever (YFV) is effective but represents a risk for patients with egg allergy because of its ovalbumin content. (Source: Journal of Allergy and Clinical Immunology)

Yellow fever virus infection in human hepatocyte cells triggers an imbalance in redox homeostasis with increased reactive oxygen species production, oxidative stress, and decreased antioxidant enzymes
Free Radic Biol Med. 2024 Mar;213:266-273. doi: 10.1016/j.freeradbiomed.2024.01.042. Epub 2024 Jan 24.ABSTRACTYellow fever (YF) presents a wide spectrum of severity, with clinical manifestations in humans ranging from febrile and self-limited to fatal cases. Although YF is an old disease for which an effective and safe vaccine exists, little is known about the viral- and host-specific mechanisms that contribute to liver pathology. Several studies have demonstrated that oxidative stress triggered by viral infections contributes to pathogenesis. We evaluated whether yellow fever virus (YFV), when infecting human hepatocytes ...

The spread of Aedes albopictus (Diptera: Culicidae) in the islands of S ão Tomé and Príncipe
We report the presence of the species in Príncipe for the first time, suggesting that the range of Ae. albopictus is larger than previously thought. Finally, we use bioclimatic niche modeling to infer the potential range of Ae. albopictus and infer that the species has the potential to spread across a large portion of São Tomé and Príncipe. Our results suggest that Ae. albopictus has established itself as a resident species of the islands of the Gulf of Guinea and should be incorporated into the list of potential vectors that need to be surveyed and controlled.PMID:38185188 | DOI:10.1016/j.actatropica.2023.107106 (Source: Acta Tropica)

Viruses, Vol. 16, Pages 84: Mechanisms of Yellow Fever Transmission: Gleaning the Overlooked Records of Importance and Identifying Problems, Puzzles, Serious Issues, Surprises and Research Questions
o
In viral disease research, few diseases can compete with yellow fever for the volume of literature, historical significance, richness of the topics and the amount of strong interest among both scientists and laypersons. While the major foci of viral disease research shifted to other more pressing new diseases in recent decades, many critically important basic tasks still remain unfinished for yellow fever. Some of the examples include the mechanisms of transmission, the process leading to outbreak occurrence, environmental factors, dispersal, and viral persistence in nature. In this review, these subjects are analyze...
