The authors give an account of the development of the definition and context of epidemiological surveillance during the past decades in Czechoslovakia and in the world. They analyze views of epidemiologists who contributed in a major way to the modern concept of surveillance. The concept of surveillance reflects social conditions in the widest sense of the word and its contents are and probably will also in future be the subject of lively discussions. The authors assume that in the near future a more important part will be played by an active approach to surveillance of infections, as no modern system of health care can do without its development. Contemporary social changes will play a decisive role.

Hepatocelulární karcinom (HCC) je celosvětově druhou nejčastější příčinou úmrtí na nádorová onemocnění. V 90 % případů vzniká HCC v souvislosti s anamnézou jaterní cirhózy, nejčastěji při hepatitidě B a C. Surveillance HCC je založena na pravidelném vyšetření pacientů ve zvýšeném riziku vzniku nádoru s cílem snížit mortalitu spojenou s onemocněním. Cílovou populací k surveillance HCC jsou pacienti s jaterní cirhózou, nezávisle na její etiologii. Screening HCC můžeme provádět pomocí sérologických testů a zobrazovacích metod. V současné době je nej-užívanější vyšetřovací metodou pro screening HCC ultrasonografie (USG), která má přijatelnou diagnostickou přesnost. Ze sérologických testů je nejčastěji používaným markerem ve screeningu HCC α-fetoprotein, má být však ve screeningu použit pouze v situacích, v nichž USG vyšetření není dostupné. USG vyšetření je v současné době vše-obecně doporučovanou metodou surveillance HCC s 6měsíčním intervalem mezi jednotlivými vyšetřeními.

BACKGROUND: Meningococcal disease continues to be a global public health concern due to its epidemic potential, severity, and sequelae. The global epidemiological data on circulating meningococcal serogroups have never been reviewed concurrently with the laboratory capacity for meningococcal surveillance at the national level. We, therefore, aimed to conduct a country-level review of meningococcal surveillance, serogroup distribution, and vaccine use. METHODS: We conducted a systematic literature review across six databases to identify studies (published January 1, 2010 to October 16, 2017) and grey literature reporting meningococcal serogroup data for the years 2010-2016. We performed independent random effects meta-analyses for serogroups A, B, C, W, X, Y, and other. We developed and circulated a questionnaire-based survey to surveillance focal points in countries (N = 95) with known regional bacterial meningitis surveillance programs to assess their surveillance capacity and summarized using descriptive methods. RESULTS: We included 173 studies from 59 countries in the final analysis. The distribution of meningococcal serogroups differed markedly between countries and regions. Meningococcal serogroups C and W accounted for substantial proportions of meningococcal disease in most of Africa and Latin America. Serogroup B was the predominant cause of meningococcal disease in many locations in Europe, the Americas, and the Western Pacific. Serogroup Y also caused many cases of meningococcal disease in these regions, particularly in Nordic countries. Survey responses were received from 51 countries. All countries reported the ability to confirm the pathogen in-country, while approximately 30% either relied on reference laboratories for serogrouping (N = 10) or did not serogroup specimens (N = 5). Approximately half of countries did not utilize active laboratory-based surveillance system (N = 22). Nationwide use of a meningococcal vaccine varied, but most countries (N = 36) utilized a meningococcal vaccine at least for certain high-risk population groups, in private care, or during outbreaks. CONCLUSIONS: Due to the large geographical variations in circulating meningococcal serogroups, each country should continue to be monitored for changes in major disease-causing serogroups in order to inform vaccine and control policies. Similarly, laboratory capacity should be appropriately scaled up to more accurately understand local epidemiology and disease burden, as well as the impact of vaccination programs.

Surveillance is a comprehensive system of epidemiological work involving continuous collection, analysis and distribution of data on all characteristics of the disease. Among health professionals, surveillance in connection with noninfectious diseases is not as known as in infections where it has clearly proven successful. The principle of epidemiological surveillance may be applied in chronic noninfectious diseases but certain pitfalls and differences between this category and infectious diseases need to be borne in mind. These diseases have multifactorial etiology; their development is contributed to by several risk factors, mainly those associated with lifestyle; they have a long preclinical period with no apparent problems; data on their prevalence in populations may vary depending on the definition and diagnostic criteria used. Epidemiological surveillance as a continuous process aids in understanding the extent of the risk of a disease in a population, contributes to provision of early and effective care and control over their prevalence. The paper aims to describe the specific aspects of surveillance in chronic noninfectious diseases.

OBJECTIVE: Acute flaccid paralysis (AFP) is a major neurological problem. Turkey has accepted over 4 million refugees since 2011 due to the wars in neighbouring countries. In the long term, refugees can have adverse effects on the limited resources of health, sanitation, water supply, foodstuff, and shelter services of host countries, precipitating the transmission and spread of enteroviruses causing AFP. This study examines the 13-year surveillance and incidence of AFP cases in southeast Turkey, and questions possible impact of refugee movements on these parameters, comparing the periods before (2007-2010) and after (2011-2019) 2011, when the refugee movements emerged. METHODS: The records of cases reported from southeast part of Turkey with suspected AFP between January 2007 and December 2019 were reviewed retrospectively. RESULTS: Of the patients, 121 (58.5%) were male. Mean age was 80.36 ± 46.67 months. Eighty-five (41.1%) were aged 60 months or younger. The number of patients under 60 months increased significantly after 2011. Mean incidence was calculated as 0.88 cases/100,000 person years versus 1.58 cases/100,000 person years in the period before and after 2011, respectively. Guillain-Barré syndrome (GBS) was the most common cause of AFP in both periods. As of 2011, however, the incidence of acute transverse myelitis increased approximately 4 times and GBS decreased proportionally. Non-polio enteroviruses were the most frequent isolates, detected from 9.1% of stool samples. CONCLUSION: Although refugee movements appear to may have adverse effects on AFP incidence and surveillance outcomes, larger studies involving the whole country, particularly at places where no refugees settled, are needed to achieve more conclusive evidence.

BACKGROUND: The Global Influenza Hospital Surveillance Network (GIHSN) aims to determine the burden of severe influenza disease and Influenza Vaccine Effectiveness (IVE). This is a prospective, active surveillance and hospital-based epidemiological study to collect epidemiological data in the GIHSN. In the 2016-2017 influenza season, 15 sites in 14 countries participated in the GIHSN, although the analyses could not be performed in 2 sites. A common core protocol was used in order to make results comparable. Here we present the results of the GIHSN 2016-2017 influenza season. METHODS: A RT-PCR test was performed to all patients that accomplished the requirements detailed on a common core protocol. Patients admitted were included in the study after signing the informed consent, if they were residents, not institutionalised, not discharged in the previous 30 days from other hospitalisation with symptoms onset within the 7 days prior to admission. Patients 5 years old or more must also complied the Influenza-Like Illness definition. A test negative-design was implemented to perform IVE analysis. IVE was estimated using a logistic regression model, with the formula IVE = (1-aOR) × 100, where aOR is the adjusted Odds Ratio comparing cases and controls. RESULTS: Among 21,967 screened patients, 10,140 (46.16%) were included, as they accomplished the inclusion criteria, and tested, and therefore 11,827 (53.84%) patients were excluded. Around 60% of all patients included with laboratory results were recruited at 3 sites. The predominant strain was A(H3N2), detected in 63.6% of the cases (1840 patients), followed by B/Victoria, in 21.3% of the cases (618 patients). There were 2895 influenza positive patients (28.6% of the included patients). A(H1N1)pdm09 strain was mainly found in Mexico. IVE could only be performed in 6 sites separately. Overall IVE was 27.24 (95% CI 15.62-37.27. Vaccination seemed to confer better protection against influenza B and in people 2-4 years, or 85 years old or older. The aOR for hospitalized and testing positive for influenza was 3.02 (95% CI 1.59-5.76) comparing pregnant with non-pregnant women. CONCLUSIONS: Vaccination prevented around 1 in 4 hospitalisations with influenza. Sparse numbers didn't allow estimating IVE in all sites separately. Pregnancy was found a risk factor for influenza, having 3 times more risk of being admitted with influenza for pregnant women.

Poliomyelitis anterior acuta is an acute infectious disease caused by polioviruses of three antigenic types. First epidemics of poliomyelitis emerged at the end of the 19th century. The World Health Organization launched the poliomyelitis eradication program in 1988. The incidence of poliomyelitis in the world decreased from 350,000 cases in 1988 to 1918 cases in 2002 when poliomyelitis eradication was certified in three WHO regions, the European Region (2002), American Region (1994) and West Pacific Region (2000). Systematic clinico-virological surveillance of poliomyelitis has been carried in the Czech Republic since 1961, including annual vaccination campaigns with living OPV vaccine, clinical screening, virological screening of clinical specimens and sewage water (environmental) samples and sera screening within serological surveys mapping the vaccination immunological efficacy. From 1961 to 2003, 21,423 stool specimens of vaccinated healthy children, 62,440 stool specimens of patients, 6250 cerebrospinal fluid specimens and 2100 throat swab specimens were screened. Within the outdoor environment surveillance, 15,460 sewage water samples were analysed. From 1995 to 2003 129 cases of acute flaccid paresis were investigated in children under 15 years of age and 28 stool samples from their contacts were screened. Over the same period, 1280 sewage water samples from refugee camps were analysed. For serological surveys, about 60,000 sera from healthy individuals of all age categories were investigated. No case of paralytic poliomyelitis has been reported and no wild virus has been isolated in the Czech Republic since 1961.

OBJECTIVES: Seasonal influenza causes high morbidity worldwide and high mortality in developing countries. As a result, the development of systems for seasonal influenza surveillance has been of great interest. The aim of this study is to explore the potential role of an Emergency Medical System (EMS) call centre to complement traditional surveillance systems of seasonal influenza. METHODS: Retrospective observational study in which data on influenza from the system of Notifiable Diseases List (Spanish acronym EDO) and Sentinel Physicians Network (Spanish acronym RMC) were compared with information on calls made to the Principality of Asturias EMS call centre that covers all the region population (1,027,659 inhabitants) based on a set of specific criteria to determine differences and explore this emergency call system as a complementary epidemiological surveillance system. Cases registered by different systems have been compared to the same 68 weeks period, from week 45 of 2011 to week 8 of 2013. RESULTS: RMC reported a total of 2,354 cases of influenza, EDO 43,071 cases and EMS call centre 4,360 "case calls" out of 180,720 total emergency calls. Case series of EDO and EMS call centre have shown a positive correlation (R = 0.42, p = 0.003). Case series from EMS call centre and RMC were correlated (R = 0.38, p = 0.007). Case series from EDO and RMC have shown a strong positive correlation (R = 0.91, p < 0.001). Correlation analysis of the cases reported by the three systems have shown a significant positive correlation between them (p < 0.001). The spike of EMS calls related to the studied influenza syndrome occurs one week in advance compared to traditional epidemiological surveillance systems. CONCLUSIONS: EMS call centre data on influenza could be potentially used as a complementary surveillance system to the traditional epidemiological surveillance systems for influenza.
