Measles – retrospective study of cases reported in a national notification system, Czech Republic, 2018–2024
In response to the recent increase in measles cases and outbreaks across Europe, Czech surveillance data were analysed. The aim was also to evaluate the effect of vaccination on measles complications. Cases of measles reported to the national surveillance system according to the EU case definition (2018) between 2018–2024, were analysed. Demographic characteristics were assessed using descriptive analysis (counts and proportions). Logistic regres…
Links between influenza epidemics, weather characteristics and all-cause mortality in the Czech Republic, 1982–2020
The findings suggest that weather indicators, particularly air temperature and absolute humidity, play an important role in the timing and severity of epidemics, and that these parameters differ with the predominant influenza virus. In the temperate climate of Central Europe, the circulation of the A/H3N2 virus in the population, combined with prolonged periods of low temperatures, results in influenza epidemics with the largest excess mortality.…
Vaccination against influenza in pregnant women in a maternity hospital in the Czech Republic in the season 2020–2021
The IVC during pregnancy in our study was extremely low. In order to improve IVC among pregnant women, it is necessary to increase awareness of recommendations and vaccination options among the public and professionals and incorporating vaccination recommendation in routine antenatal practice
Influence of air temperature and implemented veterinary measures on the incidence of human salmonellosis in the Czech Republic during 1998–2017
Significant non-linear effects of annual trend, within-year seasonality, and air temperature on the incidence of salmonellosis during 1998-2017 were found. Our study also demonstrates significant direct effect of preventive veterinary measures taken in poultry in reducing incidence of human salmonellosis in the CZ. The annual mean number of salmonellosis cases in the period after introducing the veterinary measures was only 32.5% of what it had b…
Influenza epidemiology and influenza vaccine effectiveness during the 2016–2017 season in the Global Influenza Hospital Surveillance Network (GIHSN)
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
Estimates of global seasonal influenza-associated respiratory mortality
Protective effect of vaccination against mumps complications, Czech Republic, 2007–2012
This study demonstrates a significant preventive effect of two-dose vaccination against mumps complications (orchitis, meningitis, or encephalitis) and hospitalization for mumps. The risk of complications increases with time interval from vaccination. Teenagers and young adults were the most affected age groups
Influenza epidemiology and influenza vaccine effectiveness during the 2014–2015 season
The Global Influenza Hospital Surveillance Network (GIHSN) has established a prospective, active surveillance, hospital-based epidemiological study to collect epidemiological and virological data for the Northern and Southern Hemispheres over several consecutive seasons. It focuses exclusively on severe cases of influenza requiring hospitalization. A standard protocol is shared between sites allowing comparison and pooling of results. During the …
Impacts of hot and cold spells differ for acute and chronic ischaemic heart diseases
The findings show that while excess deaths due to IHD during hot spells are mainly of persons with chronic diseases whose health had already been compromised, cardiovascular changes induced by cold stress may result in deaths from acute coronary events rather than chronic IHD, and this effect is important also in the younger population. This suggests that the most vulnerable population groups as well as the most affected cardiovascular diseases d…
Excess cardiovascular mortality associated with cold spells in the Czech Republic
The results show that cold stress has a considerable impact on mortality in central Europe, representing a public health threat of an importance similar to heat waves. The elevated mortality risks in men aged 25-59 years may be related to occupational exposure of large numbers of men working outdoors in winter. Early warnings and preventive measures based on weather forecast and targeted on the susceptible parts of the population may help mitigat…
