RESUMO
Enteroviruses are common causes of infections of the central nervous system (CNS) that in temperate climates tend to peak in the summer. The aim of the study was to describe epidemiology, drivers of seasonality, and types of enteroviruses causing infections of the CNS in children in Northeastern Poland. We prospectively collected data on children hospitalized with infection of the CNS attributed to enteroviruses in Bialystok, Poland, from January 2015 to December 2019. In total, 224 children were included. Nineteen different enterovirus types were identified in isolates collected from 188 children. Coxsackie B5 (32%), echovirus 30 (20%), and echovirus 6 (14%) were the three most common types. Enteroviruses were more prevalent during the summer-fall season. Infections caused by echovirus 30 peaked early in June and coxsackievirus B5 in July, whereas echovirus 6 peaked late in October. Phylogenetic analyses of these three enterovirus types showed multiple lineages co-circulating in this region. Mean air temperatures and precipitation rates were independently associated with monthly number of cases. Considering lack of effective treatment or vaccine, easy transmission of enteroviruses between susceptible individuals, their high mutation rate and prolonged time of viral shedding, continued monitoring and surveillance are imperative to recognize enteroviral infections of the CNS and the changes in circulation of enteroviruses in Poland.

Jamestown Canyon virus (JCV), a mosquito-borne Orthobunyavirus (within the California serogroup), can cause severe neuroinvasive disease. According to national data during 2000-2013, 42% of the 31 documented JCV disease cases in the United States were detected in residents from Wisconsin. The Wisconsin Division of Public Health enhanced JCV surveillance by implementing routine use of JCV-specific immunoglobulin M (IgM) antibody testing followed by confirmatory JCV-specific plaque reduction neutralization testing on all patients with suspected cases of arboviral infection who had tests positive for arboviral immunoglobin at commercial laboratories. During 2011-2016, of the 287 Wisconsin specimens tested on the Arbovirus IgM Antibody Panel, 30 JCV cases were identified (26 confirmed and four probable). Twenty-seven (90%) JCV cases were detected after 2013. Among all cases, 17 (56%) were male and the median age was 54 years (range: 10-84 years). Fifteen patients had neuroinvasive disease, including meningitis (n = 9) and meningoencephalitis (n = 6). Although historically considered rare, the relatively high rate (0.12 cases/100,000 population) of diagnosis of JCV infections among Wisconsin residents during 2013-2016 compared with that in previous years suggests occurrence is widespread throughout Wisconsin and historically may have been under-recognized. This study aims to raise awareness of JCV infection for differential diagnosis among the arboviral diseases. Improved and timely diagnosis of arboviral disease is important in that it will provide more information regarding emerging infections and promote preventive measures to avoid mosquito-borne exposure and infection among residents of and visitors to affected areas.

BACKGROUND: The "health spillover" of patient illness on family members is important to capture in economic evaluation. This study compares the construct validity and responsiveness of 2 widely used health-related quality-of-life instruments, the EQ-5D-5L and SF-6D, in capturing health spillover effects for family members with and without an informal care role (carers and noncarers). METHODS: Construct validity and responsiveness were assessed using data from a 2012 UK survey of the family impact of meningitis-related sequelae. Construct validity was assessed by testing associations between family members' health status and variables anticipated to be associated with spillover effects (patient health status and informal care). Responsiveness was assessed by testing associations between the longitudinal change in family members' health status and longitudinal change in patient health and caring hours. RESULTS: Among noncarers, both the EQ-5D-5L and the SF-6D exhibited construct validity with 10 of the 11 associations that were hypothesized being statistically significant on both measures. There was less clear evidence of responsiveness of the measures for noncarers. Among carers, the EQ-5D-5L exhibited greater construct validity, as well as responsiveness, with respect to spillovers from patient health. This was evidenced by the EQ-5D-5L detecting 9 significant associations compared with 4 on the SF-6D. However, the SF-6D exhibited greater construct validity with respect to spillovers generated from informal care provision (5 associations significant compared with 2 on the EQ-5D-5L). CONCLUSION: Both the EQ-5D-5L and the SF-6D exhibited a degree of validity that could justify their use as measures of health-related quality-of-life spillovers on family members in economic evaluation.

AIM: Study the manifestations of epidemic process and leading transmission routes of causative agents of enterovirus serous meningitis (SM) by results of laboratory studies and epidemiologic examination of epidemic nidi. MATERIALS AND METHODS: During 2010 - 2014 a study for enterovirus was carried out in cerebrospinal fluid in 743 patients, hospitalized into medical organizations of Perm with primary diagnosis "serous meningitis", feces of 426 individuals, that had communicated with patients with SM of enterovirus etiology; 827 water samples from the distribution network, 295 water samples from open water and 57 washes from surface of vegetables and fruits. All the samples were studied in polymerase chain reaction, part--by a virological method. Epidemiologic examination of 350 epidemic nidi of SM was carried out. RESULTS: Enterovirus and (or) its RNA were detected in 62.0% of patients and 61.9% of individuals that had communicated with patients with enteroviris SM. ECHO 6 serotype enterovirus dominated among the causative agents. Maximum intensity of epidemic process of enterovirus SM, based on data from laboratory examination of patients, was detected in a group of organized pre-school and school age children during summer-autumn period. CONCLUSION: . Examination of epidemic nidi and laboratory control of environmental objects have shown that CV causative agent transmission factors are, in particular, unboiled water from decentralized sources (boreholes, wells, springs), water from open waters during bathing, as well as fresh vegetables, fruits, berries and meals produced from them. .

In cases of central nervous system infection, it is crucial for the neuroradiologist to provide an accurate differential diagnosis of the possible pathogens involved so that treating physicians can be aided in the choice of empiric therapy. This approach requires the radiologist to be aware of local epidemiology and have knowledge of infectious agents that are endemic to their area of practice. This article reviews and discusses the changing epidemiology of pathogens most often observed in meningitis, brain abscess, epidural abscess, postoperative infections, and human immunodeficiency virus infection.

Toscana virus which is an arbovirus transmitted to humans by sandflies (Phlebotomus spp.), can cause febrile illness and meningitis mainly during summer. It has a tropism for central nervous system and is a major cause of meningitis and encephalitis in endemic countries. Majority of the clinical and epidemiologic studies on Toscana virus have been reported from Italy, France, Spain, Portugal and other Mediterranean countries. Although Toscana virus infections has been identified, data on virus activity in Turkey are limited. In this review article, the epidemiological, clinical and laboratory features of Toscana virus as a cause of febrile diseases, meningitis and encephalitis during summer in Turkey were discussed.

Presentamos un caso de meningitis por enterovirus diagnosticada mediante reacción en cadena de polimerasa en una recién nacida en 37 semanas de edad gestacional y seis días de vida, de probable etiología congénita. Las infecciones por enterovirus constituyen una causa frecuente de infección en recién nacidos pese a no estar incluidas en el diagnóstico diferencial habitual de la sepsi neonatal. La presencia de clínica materna compatible puede orientar el diagnóstico en los casos de transmisión vertical. Su identificación precoz en estos casos permite acortar el tratamiento antibiótico empírico innecesario y la hospitalización y realizar un adecuado seguimiento de las posibles complicaciones. El tratamiento antiviral con pleconaril se contempla en casos graves, aunque actualmente la indicación de tratamiento en neonatos no está bien establecida. El caso descrito siguió una evolución favorable con pruebas de neuroimagen y seguimiento neurológico hasta los seis meses de vida normal. En el trabajo se revisan las manifestaciones clínicas, el diagnóstico y las perspectivas actuales de tratamiento de las infecciones neonatales pro enterovirus (AU)
We report a case of a 36 week gestational age female diagnosed with enterovirus meningitis by polymerase chain reaction at 6 days of age, probably by congenital transmission. Enterovirus are a common cause of neonatal infection, frequently under diagnosed because they are not usually included in the differential diagnoses of the neonatal sepsis. Maternal compatible symptoms could help to the diagnoses in the cases with vertical transmission. An early enterovirus identification may reduce the length of antibiotic treatment and hospitalization and allow an accurate follow up, alerting of complications. Antiviral treatment with pleconaril is accepted in severe cases, but nowadays there is a lack of consensuate indication for the treatment of neonatal a enterovirus infections. The evolution of the present case was favorable with a normal neurological development until the sixth month of age and without abnormalities in the neuroimaging. This article reviews the clinical manifestations, the diagnoses and the potential treatment for enterovirus infections in (AU)

To date, the International Committee for Taxonomy of Viruses recognizes that the family Arenaviridae contains a unique genus Arenavirus that includes 22 viral species. There are nine additional arenaviruses that either have been discovered recently, or which taxonomic status remains pending. Arenaviruses have been classified according to their antigenic properties into two groups, the Lassa-Lymphocytic choriomeningitis (LCM) serocomplex and the Tacaribe serocomplex which has been further divided into four evolutionary lineages. Each arenavirus is more or less tightly associated with a mammal host. The distribution of the host dictates the distribution of the virus. Humans may become infected by arenaviruses through direct contact with infected rodents, including bites, or through inhalation of infectious rodent excreta and secreta. Lassa, Junin, Machupo, Guanarito, and Sabia viruses are known to cause a severe hemorrhagic fever, in western Africa, Argentina, Bolivia, Venezuela, and Brazil, respectively. Infection by LCM virus can result in acute central nervous system disease, congenital malformations, and infection in organ transplantation recipients. Detection of arenaviruses in their animal host can be achieved by virus isolation, and has recently taken advantage of PCR-based techniques. The approach based on consensus degenerate primers has shown efficient for both detection of known arenaviruses, and discovery of new arenaviruses.

In middle and eastern European countries, tick-borne encephalitis (TBE) is one of the most important human infections of the central nervous system. TBE virus (TBEV) is mainly transmitted by tick bites and rarely by unpasteurized milk. In European countries, TBE presents as meningitis in about 50% of patients, as meningoencephalitis in 40%, and as meningoencephalomyelitis in 10%. The severity of TBE increases with age; in children and adolescents, meningitis is the predominant form of the disease. The long-term prognosis is unfavorable in about 40% to 50% of patients who sustain sequelae for months to years, mainly in terms of pareses, ataxia, and other gait disturbances. No specific treatment for TBE is known. It can be successfully prevented by active immunization.

HISTORY AND CLINICAL FINDINGS: A 69-year-old man was admitted to our hospital with severe headache, recurrent episodes of fever and deterioration of general health. He returned from a vacation in Tuscany (Italy) a few days before admission. Physical examination revealed slight nuchal rigidity and an elevated body temperature of 37.8 C but was otherwise unremarkable. INVESTIGATIONS: Differential blood count showed a lymphocytopenia. Other abnormal laboratory findings included an elevated blood sedimentation rate and a slightly increased C-reactive protein value. Abdominal sonography demonstrated a marginally enlarged spleen. DIAGNOSIS, TREATMENT AND CLINICAL COURSE: A lumbar puncture was performed. Cerebrospinal fluid analysis revealed a lymphocytic meningitis. Serological examination of a blood sample showed specific IgM-antibodies against sandfly fever Naples virus (SFNV), subtype Toscana virus (TOSV). After this diagnosis had been made initially instituted intravenous administration of antibiotics and antiviral medication were discontinued. The patient's symptoms improved rapidly under symptomatic treatment. Slight headaches without episodes of fever persisted for a few weeks without residual neurological symptoms. CONCLUSIONS: A history of travel should always be sought in patients with clinical signs for meningitis. Considering the increasing spread and incidence of SFNV and its subtype Toscana in mediterranean countries, such virus should be kept in mind when treating patients who present such symptoms after returning from those countries during the summer season.

From July to October 2001, 215 cases of aseptic meningitis occurred among the inhabitants of the German city of Kassel and neighbouring counties. A matched case-control study identified bathing in a public, nature-like pond during the beginning of the outbreak as a risk factor for disease [matched odds ratio (mOR) 44.8, 95% confidence interval (CI) 3.9-515.6]. Among bathers, patients with meningitis spent more time in the water (mOR 18.8, 95% CI 2.0-174.1) and swallowed water more frequently (mOR = 7.3, 95% CI 0.7-81.8). Of 30 cerebrospinal fluid samples tested, echovirus 30 was cultured from 16, and echovirus 13 from seven. An echovirus 30 sequence obtained from one pond water sample showed a 99% nucleotide and 100% amino-acid homology with patient isolates. This outbreak demonstrates the potential of nature-like swimming ponds to cause widespread community infection with substantial public health impact.

We investigated six cases of enterovirus infection in a neonatal unit. The index patient, a 5-day-old boy, was admitted with aseptic meningitis due to echovirus 30 (E30). Secondary infections with E30 occurred in five babies. Comparison of the complete VP1 sequences showed that the isolates recovered from the index patient and his mother were closely related to those recovered from the five babies with secondary infections, demonstrating a nosocomial transmission of the virus. In the phylogenetic tree reconstructed from the VP1 sequences, the isolates formed a monophyletic cluster related to an E30 strain collected in June 1997 during an outbreak of aseptic meningitis.

OBJECTIVE: A report of five cases of viral meningitis among adults with children enrolled in a child care center prompted an investigation of risk factors for viral transmission from children to adult household members. METHODS: To determine recent echovirus 30 (E30) infections, the authors conducted a serologic survey. To determine risk factors for infection among adult household members, they conducted a retrospective cohort study using written questionnaires. RESULTS: Recent E30 infections were found in 84% of children tested, 57% of adult household members tested, and 47% of staff members tested. Infected adults were more likely than infected children to have clinical meningitis. Among adult household members, changing diapers was a risk factor for recent infection. Women who changed > or = 90 diapers per month had a higher infection rate than women who changed fewer diapers; in contrast, men who changed > or = 90 diapers per month had a lower infection rate than men who changed fewer diapers. Handwashing was protective: there was a negative correlation between handwashing after diaper changes and E30 infection among adults with infected children in diapers. CONCLUSIONS: Because child care centers can be a source of enteroviral infections among adult household members, adults with viral meningitis should be questioned about their children's day care or preschool attendance. The importance of handwashing should be stressed to adults with children in day care.

This article discusses the infectious disease meningitis--a notifiable disease since 1912 (Payling, 1994). The major concern is bacterial meningitis and in particular the meningococcal cause. Viral meningitis is also considered. Some 50% of cases of meningitis in the UK are of the viral kind, where the patient usually makes a full recovery and in some instances may not be aware of having contracted the disease (Payling, 1994). Cases of bacterial meningitis are few and if treated effectively and with urgency can result in full recovery; however, any delay may result in fatal sequelae. Bacterial meningitis occurs mainly as a result of meningococcal, pneumococcal or Haemophilus influenzae type B (Hib) infection. The latter has largely been eradicated in England and Wales as a result of effective immunization programmes. The nurse must develop an awareness of the disease, and diagnose it at an early stage. He/she should know the procedures for referring the patient to prevent an escalation of the infection and to reduce the severity of its effects.

Sandfly fever virus is known to cause pappataci fever. The sandfly fever virus belongs to the Genus Phlebovirus (family: Bunyaviridae) and is endemically found in areas of South Europe, Asia and Africa. In Germany, pappataci fever is only described in connection with travelling to endemic areas. We report on a 15 year-old girl suffering from sandfly fever virus infection after vacation in Turkey. The initial symptoms started with fever for about three days, frontal headache, nausea and arthralgia. After a short time of clinical improvement symptoms recurred and our patient entered hospital with signs of severe meningitis. Liquor analysis showed a lymphocytic meningitis. Due to multiple insect bites on her legs sandfly fever was suspected. Blood analysis confirmed an acute infection with sandfly virus Sicilian from which she completely recovered. ELISA and immunoblot analysis revealed an infection with sandfly virus serotype Sicilian, which was not encountered with meningitis so far. Our case report illustrates that due to increased tourism sandfly fever virus infection has to be considered as a cause of aseptic meningitis in travellers.
