Enterovirus 71-Associated Infection in South Vietnam: Vaccination Is a Real Solution.

Hand-foot-and-mouth disease (HFMD) is the most common enteroviral infection in South-East Asia. When evaluating the role of enterovirus 71 (EVA71) as an etiological agent of infectious disease in South Vietnam, we revealed a high proportion of EVA71 among identified species A enteroviruses found in 3542 samples from HFMD cases; 125 samples from cases of enteroviral meningitis; and 130 samples from acute flaccid paralysis (AFP) cases. These represent 50%, 54.

Cases of Acute Flaccid Paralysis Associated with Coxsackievirus A2: Findings of a 20-Year Surveillance in the Russian Federation.

Surveillance for acute flaccid paralysis syndrome (AFP) in children under 15 is the backbone of the Global Polio Eradication Initiative. Laboratory examination of stool samples from AFP cases allows the detection of, along with polioviruses, a variety of non-polio enteroviruses (NPEV). The etiological significance of these viruses in the occurrence of AFP cases has been definitively established only for enteroviruses A71 and D68.

[Group enterovirus infection due to coxsackievirus A16 in Northwestern Russia].

Aim: Study features of epidemic process and etiology of oral cavity and limb enterovirus exanthema group diseases in a number of territories of Northwestern Russia.

Materials And Methods: Isolation and identification of non-poliomyelitis enteroviruses from material of patients was carried out according to WHO recommendations. Phenotyping and phylogenetic analysis of enteroviruses was carried out.

[Molecular genetic echovirus 9 variants identified in patients with aseptic meningitis in Russia in 2007-2009].

In 2009 echovirus 9 caused a higher seasonal incidence of enterovirus infection (EVI) and its several outbreaks in a number of regions of Russia. Analysis of the partial VP1 coding region differentiated 4 phylogenetic lineages of echoviruses 9 variants identified in patients with aseptic meningitis and EVI in 2007-2009. One variant of echovirus 9 was most commonly encountered in 2009.

[Aseptic meningitis season caused by enteroviruses in 2007: molecular-epidemiological aspects].

Aim: Analysis of manifestation of epidemic process of aseptic meningitis and causes of its activation using molecular genetic methods.

Materials And Methods: Samples of feces and CSF, nasopharyngeal swabs from 296 patients with aseptic meningitis (AM), as well as 240 samples of drinking water and 6 samples of lake water were studied. Epidemiologic analysis, isolation of enteroviruses in Hep-2 and RD cell cultures, RT-PCR, partial sequencing of 5'NTR and genome region coding VP1 were performed.
