Hospitalizations related to meningococcal infection in Spain from 1997 to 2018

Abstract Background Baseline hospitalization, mortality, and in-hospital fatality rates for meningococcal infection are required to evaluate preventive interventions, such as the inclusion of the conjugated quadrivalent meningococcal vaccine and serogroup B based protein vaccines. Methods All meningococcal infection–related hospitalizations in any diagnostic position in Spain from 1st January 1997 through 31st December 2018 were analysed. The annual hospitalization rate, mortality rate and case-fatality rate were calculated. Results The average hospitalization rate for meningococcal infection was 1.64 (95% CI 1.61 to 1.66) hospitalizations per 100,000 inhabitants during the study period and significantly decreased from 1997 to 2018. Hospitalizations for meningococcal infection decreased significantly with age and were concentrated in children under 5 years of age (46%). The hospitalization rates reached 29 per 100,000 and 24 per 100,000 children under 1 and 2 years of age, respectively. The in-hospital case-fatality rate was 7.45% (95% CI 7.03 to 7.86). Thirty percent of the deaths occurred in children under 5 years of age, and more than half occurred in adults. The case fatality rate increased significantly with age (p < 0.001). Conclusion It is necessary to maintain epidemiological surveillance of meningococcal infection to determine the main circulating serogroups involved, track their evolution, and evaluate preventive measures whose effectiveness must be assessed in all age groups.

To assess the epidemiological trend in hospital admission, including morbidity and mortality pattern of illness in the pediatric population, it needs to develop effective health care planning, appropriate resource allocation, and integration of existing health care service facilities. Objective: To evaluate the diseases and deaths of children admitted in the department of pediatrics, Rajshahi medical college hospital, Rajshahi. Materials and methods: This is a retrospective study. The collected case records of all patients admitted in the department of pediatrics from 1st January 2017 to 31st December 2019 (3 years) were analyzed. Result: A total of 62000 children were admitted during the mentioned study period. All the patients were distributed into three age groups infant, under five, and more than five, contributing 22%, 27.5%, and 19%, respectively. Acute watery diarrhea (21%), hereditary hemolytic anemia (18%), bronchopneumonia (10.4%), acute gastritis (9.4%), and acute bronchiolitis and wheezy child (7.17%) were the top five diseases in each of the three years of admission. Among the total admitted patients, 1003 (1.61%) patients died. Infant, under five, and more than five age groups constitute 61.3%, 28.1%, and 15.1%, respectively. Encephalitis and fulminant hepatic failure found the top two diseases causing death with a case fatality rate was 61% and 43%, respectively. The next highest case fatality rate was found in acute leukemia (15%). Other common causes of death include meningitis, cerebral palsy with complications (7.5%), bronchopneumonia with complications (3.8%). Conclusion: An admission-related comprehensive evaluation of this study will help to understand the diseases and death patterns of a hospital, leading to the development of more effective planning and case management strategies.

The study was conducted on 106 E. coli isolates to determine the phylogenetic group, serotype and carriage of Class 1 integrons in isolates and ascertain their association along with other parameters with vital disease measures in broiler flocks affected with colibacillosis. Out of 32 isolates of which “O” antigen was characterized, serogroup O2 comprising of 12 (37.5%) isolates was most prevalent in the present study. Most of the isolates (85/106; 80.19%) belonged to phylogenetic group B2. Mean apparent morbidity, mortality and case fatality rate (CFR) were 3.77%, 2.32% and 61.49%, respectively. There was significant difference in number of outbreaks reported in different age groups (p less than 0.0001). Also, there was significant association between phylogenetic group and age of outbreak due to E. coli (p=0.024). Comparatively, no significant association was observed between age of outbreaks and serotypes (p=0.980). There was significant association between various disease measures and E. coli isolates affiliated to various phylogenetic groups and serotypes. All the measures (apparent morbidity, mortality and CFR) of disease were highest in outbreaks due to isolates of phylogenetic group B2 and serogroup O20. However, the measures were not significantly affected by the presence of integrons in the E. coli.

The factors associated with submersion events among <20-year-old persons that occurred in King County from 1974 to 1983 were studied to focus prevention efforts. Near-drowning (n = 103) and drowning (n = 96) victims were identified from medical examiners' reports, paramedics' reports, and hospital discharge registers. Annual incidence was 5.5; the mortality rate was 2.6 per 100,000 children. Although preschool-aged children had the largest incidence (12.8), followed by older adolescents (4.9), adolescents had the largest case fatality rate, 77%. Lake and river victims had the largest incidence, mortality, and case fatality rate; swimming pools, the smallest case fatality rate (25%). A total of 89% of all victims had absent or no supervision; victims supervised by lifeguards had a 42% case fatality rate. Prior seizures were part of the history of 7.5% of all victims; 25% of fatal submersions by adolescents were associated with alcohol. Bathtub submersions were associated with child abuse in three of 16 preschool-aged children and epilepsy in four of five older children. Certain age groups and sites combined had the greatest incidence: preschool-aged children in swimming pools, infants in bathtubs, teenagers in lakes and rivers. Incidence decreased in public and semipublic pools coincident with fencing regulations. These findings suggest prevention strategies: extending fencing requirements to private pools, discouraging alcohol consumption during water sports, changing bathing practices of epileptics, and improving lifeguard efficacy.

Background. Chagas disease (CD) is associated with excess mortality in infected people in endemic countries, but little information is available in non-endemic countries. The aim of the study was to analyze mortality in patients admitted to the hospital with CD in Spain. Methods. A retrospective, observational study using the Spanish National Hospital Discharge Database. We used the CD diagnostic codes of the 9th and 10th International Classification of Diseases to retrieve CD cases from the national public registry from 1997 to 2018. Results. Of the 5022 hospital admissions in people with CD, there were 56 deaths (case fatality rate (CFR) 1.1%, 95% confidence interval (CI) 0.8%, 1.4%), 20 (35.7%) of which were considered directly related to CD. The median age was higher in those who died (54.5 vs. 38 years; p < 0.001). The CFR increased with age, peaking in the 70–79-year (7.9%, odds ratio (OR) 6.27, 95% CI 1.27, 30.90) and 80–89-year (16.7%, OR 14.7, 95% CI 2.70, 79.90) age groups. Men comprised a higher proportion of those who died compared to survivors (50% vs. 22.6%; p < 0.001). Non-survivors were more likely to have neoplasms (19.6% vs. 3.4%; p < 0.001), heart failure (17.9% vs. 7.2%; p = 0.002), diabetes (12.5% vs. 3.7%; p = 0.001), chronic kidney failure (8.9% vs. 1.6%; p < 0.001), and HIV (8.9% vs. 0.8%; p < 0.001). In the multivariable analysis, the variables associated with mortality were age (adjusted OR (aOR) 1.05; 95% CI: 1.03, 1.07), male sex (aOR 1.79, 95% CI 1.03, 3.14), cancer (aOR: 4.84, 95% CI 2.13, 11.22), and HIV infection (aOR 14.10 95% CI 4.88, 40.73). Conclusions. The case fatality rate of CD hospitalization was about 1%. The mortality risk increased with age, male sex, cancer, and HIV infection.

Abstract The number of coronavirus disease 2019 (COVID-19) cases and deaths registered in Mexico during 2020 could be underestimated, due to the sentinel surveillance adopted in this country. Some consequences of following this type of epidemiological surveillance were the high case fatality rate and the high positivity rate for COVID-19 shown in Mexico in 2020. During this year, the Mexican Ministry of Health only considered cases from the public health system, which followed this sentinel surveillance, but did not consider those cases from the private health system. To better understand this pandemic, it is important to include all the results obtained by all the institutions capable of testing for COVID-19, thus the Mexican Government could make good decisions to protect the population from this disease.

Sickle cell disease (SCD) is an inherited hemoglobinopathy that can affect nearly every organ system. Individuals living with SCD are at high risk of developing serious infections which can further trigger disease related complications and attribute additional morbidity and mortality. In light of the evolving pandemic caused by SARS-CoV-2, the causative agent of COVID-19 disease, and the potential for future infectious disease epidemics, it is important to understand the impact that COVID-19 has on hospitalization rates and mortality in this medically vulnerable population. The objective of this study was to describe hospitalization and case fatality rates secondary to COVID-19 among individuals living with SCD in different age groups and compare these to the general population. The Medical College of Wisconsin established the international SECURE-SCD Registry to collect data on pediatric and adult COVID-19 infections in individuals living with SCD. Providers are instructed to report confirmed COVID-19 cases to the registry after sufficient time has passed to observe the disease course through resolution of acute illness and/or death. For each case, providers complete a short form that includes the following data: patient demographics, COVID-19 related hospitalization, COVID-19 severity/management strategies, if the patient died due to COVID, and other information about SCD complications. Data are de-identified and without protected health information to facilitate rapid and increased reporting. We calculated the hospitalization rate and case fatality rate for individuals with SCD by specific age group and contrasted it with the rates publicly available for the general Black population. We utilized data from California Department of Public Health for case fatality rate comparison in Blacks and data from COVID-NET for hospitalization rate comparison. We used indirect age adjustment to calculate standardized mortality ratios using COVID-19 data from California state as the reference population. As of July 17th 2020, 218 cases of COVID-19 in Blacks with SCD in the US were reported to the registry. There was a slight predominance of females (52.8%) and 32.1% of reported cases were patients 18 years and under. There were 15 deaths reported with overall mortality rate of 6.9%. Figure 1 shows the distribution of cases and deaths by age group and gender. Mortality rate in SCD patients was highest in the 50-64 years age group (23.1%) in contrast to mortality rate peaks seen in the general population in patients older than 80 years (Table 1). Young adult SCD patients aged 18-34 years had a case fatality rate of 3.3% and those aged 34-50 years had a rate of 14.9%. California Department of Public Health report case fatality rates for Blacks are less than 1% in both of these comparative age groups. Age-standardized mortality ratio shows that individuals with SCD are 7.7 times more likely to die due to COVID-19 infection compared to the general population. The overall hospitalization rate in individuals with SCD was 72.5% and 18.8% of reported hospitalized cases were children. Among hospitalized adults with SCD, stratification by age showed that 85% were aged 18-49, whereas only 25.7% of people 18-49 years in the general Black population were hospitalized (Table 2). Our findings show that individuals with SCD who have COVID-19 infection have higher rates of death due to COVID-19 than the general Black population. Also, a large proportion of COVID hospitalization for the SCD population occurs among the younger age group. Further analysis is planned to examine effects of underlying comorbidities and prior SCD-associated complications on the severity of COVID-19 in individuals with SCD.

The purpose of the study is to research the morbidity, mortality and case fatality rate y of chronic viral hepatitis B without and with a delta agent from 2010–2017. in Kyrgyzstan.Materials and methods: analyzed state reporting forms No. 12 “Report on morbidity and preventive work (family medicine center, dispensary)” and “C51 — Distribution of deaths by sex, age groups and causes of death” from 2010–2017. Data processed by Microsoft Office Excel.Results: In the country from 2010–2017 3292 cases of chronic viral hepatitis B were detected, 1738 patients of them verified an independent course (СhHBV), and 1,554 patients combined with a delta agent (СhHDV), while the incidence did not have a statistically significant difference (3.80/0000, 95% CI 2.4–4.0 and 3.40/0000, 95% CI 2.2–3.4, СhHBV and СhHDV, respectively) were 20 times lower compared to the HBV Carrier (60 40/0000). There was no statistically significant difference between the cumulative morbidity, mortality, case fatality rate and the proportion of deaths in СhHBV and СhHDV. The death rate СhHBV increased by 4.7 times (0.090/0000 and 0.410/0000), case fatality rate — by 11.8 times (1355.00/0000 and 16025.60/0000) amid a decrease the incidence is 2.5 times (6.40/0000 and 2.50/0000) from 2014 to 2017, respectively. At СhHDV, the mortality rate was also increased by 4.7 times (0.030/0000 and 0.160/0000), case fatality rate — by 32.3 times (793.70/0000 and 25641.80/0000) against the background of a decrease in incidence by 6.9 times (4.40/0000 and 0.60/0000) from 2014 to 2017, respectively.Conclusion: In Kyrgyzstan from 2010–2017, relatively low detectability of chronic forms of HBV infection with and without delta agent was found, compared with the “HBV carrier”. There has been an increase in mortality and case fatality rate over the past 4 years, with a sharp rise in 2017 against the background of a downward trend in the incidence of СhHBV and СhHDV.

ABSTRACTImportanceCOVID-19 case fatality and hospitalization rates, calculated using the number of confirmed cases of COVID-19, have been described widely in the literature. However, the number of infections confirmed by testing underestimates the total infections as it is biased based on the availability of testing and because asymptomatic individuals may remain untested. The infection fatality rate (IFR) and infection hospitalization rate (IHR), calculated using the estimated total infections based on a representative sample of a population, is a better metric to assess the actual toll of the disease.ObjectiveTo determine the IHR and IFR for COVID-19 using the statewide SARS-CoV-2 seroprevalence estimates for the non-congregate population in Connecticut.DesignCross-sectional.SettingAdults residing in a non-congregate setting in Connecticut between March 1 and June 1, 2020.ParticipantsIndividuals aged 18 years or above.ExposureEstimated number of adults with SARS-CoV-2 antibodies.Main Outcome and MeasuresCOVID-19-related hospitalizations and deaths among adults residing in a non-congregate setting in Connecticut between March 1 and June 1, 2020.ResultsOf the 2.8 million individuals residing in the non-congregate settings in Connecticut through June 2020, 113,515 (90% CI 56,758–170,273) individuals had SARS-CoV-2 antibodies. There were a total of 9425 COVID-19-related hospitalizations and 4071 COVID-19-related deaths in Connecticut between March 1 and June 1, 2020, of which 7792 hospitalizations and 1079 deaths occurred among the non-congregate population. The overall COVID-19 IHR and IFR was 6.86% (90% CI, 4.58%–13.72%) and 0.95% (90% CI, 0.63%–1.90%) among the non-congregate population. Older individuals, men, non-Hispanic Black individuals and those belonging to New Haven and Litchfield counties had a higher burden of hospitalization and deaths, compared with younger individuals, women, non-Hispanic White or Hispanic individuals, and those belonging to New London county, respectively.Conclusion and RelevanceUsing representative seroprevalence estimates, the overall COVID-19 IHR and IFR were estimated to be 6.86% and 0.95% among the non-congregate population in Connecticut. Accurate estimation of IHR and IFR among community residents is important to guide public health strategies during an infectious disease outbreak.

BACKGROUND As a consequence of war and collapse of health system in Yemen, diphtheria fatal epidemic occurred at the end of 2017 OBJECTIVE This study aims to describe epidemiology of diphtheria in Yemen, determine its incidence and case fatality rate METHODS Data of patients with diphtheria was obtained from the Diphtheria program in a form of line list which were collected on daily basis by electronic Diseases Early Warning System (eDEWS). Probable case was defined as any person suffered from laryngitis or pharyngitis or tonsillitis and adherent membrane of the tonsils, pharynx and/or nose. Confirmed case was defined as probable case that is laboratory-confirmed or linked epidemiologically to laboratory-confirmed case RESULTS A total of 2,243 cases were reported during the period between July 2017 and August 2018. About 49% of cases were males and 51% of cases were females. About 44% of cases were 5 -15 years old. Respiratory tract infection was the predominant symptoms (91%) followed by psedumembrane (81%). Based on the vaccination status, the percentage of partial vaccinated patients, vaccinated, unvaccinated, and unknown were 7%, 31%, 48% and 14%, respectively. The overall incidence of diphtheria was 8 per 100,000 of population. The highest incidence was among age group <15 years (11 per 100,000) and the lowest incidence was among age group of ≥ 15 years (5 per 100,000). The overall case fatality rate (CFR) among all age groups was 5%, being higher (10%) in the age group < 5 years. . Five of difficult to access governorates had double CFR (22%) which were Raymah, Abyan , Sa'ada, Lahj, Al Jawf. CONCLUSIONS : Diphtheria in Yemen in 2017-2018 affected a significant number of people. The majority of patients were partially or not vaccinated. Children ≤ 15 years were more affected with higher fatality among children < five years. Five of difficult to access governorates had double CFR of WHO estimate. To control diphthereia epidemic in Yemn, it is recommended to increase vaccination coverage through campaigns and boosters, increase public health awareness toward diphtheria and strengthen the surveillance system for early detection and immediate response and provide antitoxin for management of severe cases.
