“…A total of 133 stool samples from a large outbreak of gastroenteritis that occurred in Samokov town between the 5th and 24th of February 2007 were investigated. A total of 977 people were reported to be involved, including individuals of all ages (epidemiological details were published elsewhere [Kamenov et al, 2007]). Stool samples were split into two portions-one for bacterial and parasitic testing and the second stored at þ48C until sending to the National Reference Enterovirus Laboratory (NREL) for virus detection.…”

Noroviruses constitute a genetically diverse group of viruses in the Caliciviridae family, and are recognized as an important cause of acute non‐bacterial gastroenteritis worldwide. To date there are no data on the incidence of noroviruses as a cause of gastroenteritis in Bulgaria. Fecal samples from an outbreak, and sporadic cases of diarrhea that occurred between December 2006 and April 2007 were tested for the presence of noroviruses. From a total of 474 stools (341 from sporadic cases and 133 cases from a single outbreak) examined, 72 samples (37 from sporadic cases and 35 from the outbreak) were positive using a norovirus‐specific enzyme immunoassay. Fifty‐nine specimens were confirmed and genotyped by RT‐PCR and sequencing of regions of the RNA‐dependent RNA polymerase and/or capsid. Sequence and phylogenetic analyses of 29 norovirus strains revealed a great diversity of norovirus genotypes among the sporadic cases including: GGII.3, GGII.4/2006a, GGII.4/2006b, GGII.20, and GGII.Karachi. A single norovirus genotype (GGII.4/2006b) was identified as the causative agent of the outbreak. This first investigation on the prevalence and molecular epidemiology of noroviruses demonstrates the significant role of these viruses as etiologic agents in acute gastroenteritis in Bulgaria. J.

The aim of the first study of viral gastroenterocolitis epidemic outbreaks during a 15-year period in a region of Bulgaria, with the elucidation of epidemiological characteristics in terms of etiological structure, clinical diversity and severity, intensity, dynamics, as well as an outline of their significance in the context of the modern level of medical development and current organization of healthcare in this country. The subject of the epidemiological survey was Sofia Province, which has specific geographic, economic, ethnic and social characteristics as neighboring with the capital. The epidemiological study considers thirteen viral gastroenterocolitis epidemic outbreaks during the period under review, characterized by intensity, range, etiology and clinical diversity. Between 2007 and 2022, 4 municipalities in the region with compact Roma population were affected - Samokov, Ihtiman, Pravets and Elin Pelin, as well as a university hospital in Sofia, providing services also to the population in the region.
