Hepatitis E virus (HEV) infection is an important public health concern in many developing countries, causing waterborne outbreaks as well as sporadic autochthonous hepatitis. HEV is mainly transmitted by the fecal-oral route in endemic areas through drinking of contaminated water. However, zoonotic transmission from animal reservoirs to humans has also(More)
To the Editor: Hepatitis E virus (HEV) is the only virus in the genus Hepevirus, which is the only member of the family Hepeviridae. HEV is the causative agent of acute hepatitis E, a moderately severe enteric disease with death rates <4% in the general population and >30% in pregnant woman (1). The virus is transmitted primarily by the fecal-oral route(More)
Herpes simplex virus type 1 (HSV-1) infection has a prevalence of 70% in the human population. Treatment is based on acyclovir, valacyclovir, and foscarnet, three drugs that share the same mechanism of action and of which resistant strains have been isolated from patients. In this aspect, innovative drug therapies are required. Natural products offer(More)
BACKGROUND Viral quasispecies can be regarded as a swarm of genetically related mutants. A common approach employed to describe viral quasispecies is by means of the quasispecies equation (QE). However, a main criticism of QE is its lack of frequency-dependent selection. This can be overcome by an alternative formulation for the evolutionary dynamics: the(More)
Two new vaccine candidates against dengue virus (DENV) infection were generated by fusing the coding sequences of the self-budding Z protein from Junin virus (Z-JUNV) to those of two cryptic peptides (Z/DENV-P1 and Z/DENV-P2) conserved on the envelope protein of all serotypes of DENV. The capacity of these chimeras to generate virus-like particles (VLPs)(More)
