INTRODUCTION The authors present recent results in the Hungarian hantavirus ecology and epidemiology. Most of the research was done between 1992-2000. AIM To determine the presence and geographic distribution of hantaviruses and to get more detailed information of human and small-mammal infection with these viruses in Hungary. METHODS For diagnostic(More)
Human enteroviruses are associated with various clinical syndromes from minor febrile illness to severe, potentially fatal conditions like aseptic meningitis, paralysis, myocarditis, and neonatal enteroviral sepsis. Between June 2000 and August 2008 echovirus (E) type 2, 4, 6, 7, 9, 11, 13, 25, 30, coxsackievirus (CV) -A16, -A19, -B5, and enterovirus 71(More)
Tick-borne encephalitis (TBE) is a common medical problem in Hungary and throughout much of Europe and Asia. This paper develops a geographic model that helps to predict the distribution of human tick-borne encephalitis cases in Hungary. The model is tested on a dataset of serologically confirmed TBE cases mapped by patients' residences. Case densities(More)
We determined the genetic variability of the 1st (CCC/ACC, P52T polymorphic variant) and 10th exons (bp 1012-1704) of the TSH receptor (TSHR) gene in Graves' disease. A total of 101 Graves' patients and 163 control subjects were screened. The A253 mutant allele was carried by nine patients with Graves' disease (8.91%) and 13 control subjects (7.98%) in(More)
We compared echovirus 11 (E11) strains implicated in a severe epidemic in Hungary in 1989 with the prototype E11 strain Gregory and with other E11 strains, most of which were isolated over the same period in Europe (Finland, The Netherlands, Romania, Russia) from sporadic cases or from environmental water. Partial sequencing indicated that the Hungarian(More)
Echovirus 11' (prime) isolates from an epidemic of haemorrhagic syndrome in departments of obstetrics in Hungary have been characterised. The leading component of the clinical disease was carditis and its lethal outcome occurred in 13 newborn babies. Maternal immunity was found to be absent even in women of 41 years of age. The application of monovalent(More)
Hungarian children were immunized with monovalent oral poliovaccine (mOPV) delivered at 6-week intervals in the order Sabin 1, Sabin 3, Sabin 2, from 1959 until 1992. During that period, 90 cases of vaccine-associated paralytic poliomyelitis (VAPP) were reported, 52 of which were associated with Sabin 3-related virus (76% of VAPP cases with virologic data).(More)
It has been suggested that human herpesvirus 8 (HHV-8), also known as KSHV (Kaposi's sarcoma-associated human herpesvirus), might possess a promoting effect in the development and progression of monoclonal gammopathies. In this study, the presence of Epstein-Barr virus (EBV), human cytomegalovirus (CMV), human herpesvirus 6 (HHV-6) and human herpesvirus 8(More)
Historical records of patients with vaccine-associated paralytic poliomyelitis (VAPP) in Hungary during 1961-1981 were reviewed to assess the risk of VAPP after oral polio vaccine (OPV) administration. A confirmed VAPP case was defined as a diagnosis of paralytic poliomyelitis and residual paralysis at 60 days in a patient with an epidemiologic link to the(More)
We describe severe tick-borne encephalitis (TBE) in a patient who had previously experienced West Nile fever, another flavivirus infection endemic in Hungary. Previous West Nile virus infection does not develop immunity either against TBE virus infection or the disease, and it does not mitigate its clinical course. The possibility of antibody-dependent(More)
