Case Ascertainment of Measles during a Large Outbreak-Laboratory Compared to Epidemiological Confirmation.

Measles is a highly contagious viral disease, and hence, sufficient herd immunity is obligatory to prevent infection transmission. Measles is still a cause of considerable disease burden globally, mainly in children. During a national measles outbreak in Israel in 2018-2019, the peak incidence rates occurred in the Jerusalem district.

SARS-CoV-2 infection characteristics among students and staff in a large high school COVID-19 outbreak and secondary transmission in households.

Background: SARS-CoV-2 clinical presentation is associated with the patients' age group. Overall, young individuals present higher proportions of asymptomatic or mild COVID-19 infection, compared to adults. Data on secondary COVID-19 transmission in households, according to the cases' age group, are accumulating.

Invasive Disease Due to : Surveillance and Trends in Israel Prior to and during the COVID-19 Pandemic.

Invasive meningococcal disease (IMD) is a devastating disease with significant mortality and long-term morbidity. The COVID-19 pandemic and containment measures have affected the epidemiology of infectious pathogens. This study's aim was to assess IMD trends in Israel prior to and during the COVID-19 pandemic.

Pertussis outbreak mainly in unvaccinated young children in ultra-orthodox Jewish groups, Jerusalem, Israel 2023.

Despite being a vaccine-preventable disease for decades, pertussis control is still a public health challenge. A pertussis outbreak emerged in Jerusalem ( = 257 cases, January to June 2023). Most cases were young children (median age 1.

Hospitalizations and Clinical Severity of COVID-19 Among Infants Under 1-Year-old.

This study evaluated COVID-19 hospitalizations and clinical severity in infants (<1-year-old, n = 2,667), March 2020-March 2021. Hospitalizations were associated with younger age [OR (95%CI): <1 month, 26.3 (16.

Measles clinical presentation, hospitalization and vaccination status among children in a community-wide outbreak.

Background: In 2018-2019, a measles outbreak emerged in Israel (4158 notified cases). We aimed to evaluate the measles characteristics and the vaccination status among children during the outbreak.

Methods: We performed a cross-sectional study of measles cases in children under 18 years, residing in the Jerusalem district (2254 notified measles cases, June 2018-May 2019).

Breastfeeding challenges and support in a high initiation population.

Background: The breastfeeding initiation rate in Israel is approximately 90%, yet exclusive breastfeeding drops sharply in the early postnatal period. The study objective was to assess early postpartum professional breastfeeding support, its association with breastfeeding success and identification of risk factors for early breastfeeding discontinuation.

Methods: As part of a post-discharge newborn follow-up study, a convenience sample of 868 mothers attending Maternal and Child Health Centers (MCHCs) up to three months post-partum were interviewed using a 26-item questionnaire.

Eligibility for growth hormone therapy in children born small for gestational age is substantially lower than expected.

Background: Growth hormone therapy is indicated for children who are both born 'small for gestational age' (SGA) and do not achieve adequate catch-up growth (ACUG).

Objective: To evaluate the actual incidence of infants born SGA and their actual ACUG.

Methods: Birth weight data from the newborn registry at two hospitals were analysed during four consecutive years.

A large COVID-19 outbreak in a high school 10 days after schools' reopening, Israel, May 2020.

On 13 March 2020, Israel's government declared closure of all schools. Schools fully reopened on 17 May 2020. Ten days later, a major outbreak of coronavirus disease (COVID-19) occurred in a high school.

Post-discharge neonatal hyperbilirubinemia surveillance.

Aim: To assess implementation of the Israel Neonatal Society's 2008 guidelines for universal community assessment of jaundice within 72 hours of discharge from birth hospitalisation.

Methods: Mothers of newborns were interviewed at Maternal Child Health Clinics in the Jerusalem District, Israel, and asked whether their newborn had been evaluated for jaundice within the recommended time frame. Newborn discharge letters from Israeli hospitals were assessed for appropriate inclusion of instructions for early follow-up for jaundice.

Community-Oriented Epidemic Preparedness and Response to the Jerusalem 2018-2019 Measles Epidemic.

Measles epidemics are still a public health challenge worldwide, necessitating a rapid response. The Jerusalem District Health Office applied a community-oriented intervention during the 2018-2019 epidemic (2150 notified cases). Program development targeted the socioeconomic and cultural characteristics of high-incidence Jewish ultraorthodox communities.

Invasive meningococcal disease epidemiology and characterization of Neisseria meningitidis serogroups, sequence types, and clones; implication for use of meningococcal vaccines.

Background And Aims: Neisseria meningitidis (N. meningitidis) is a Gram-negative bacterium that can cause life-threatening invasive infections referred to as invasive meningococcal disease (IMD). In the last decade the incidence of IMD in Israel is about 1/100,000 population annually.

Pertussis in infants under one year old: risk markers and vaccination status--a case-control study.

Background: Pertussis is a contagious bacterial disease causing substantial health burden. Pertussis-related morbidity and mortality are highest in young infants. We investigated risk markers for pertussis and vaccination status in infants.

The clinical features and long-term sequelae of invasive meningococcal disease in children.

We evaluated the outcome of invasive meningococcal disease in children <15 years of age (n = 181). Neisseria meningitidis serogroup B comprised 78% of bacterial isolates. Case fatality rate was 11.

Figuring out food labels. Young adults' understanding of nutritional information presented on food labels is inadequate.

Nutritional labelling of packaged foods, mandated by law, includes details of the food content and composition - information that can affect individual and public lifestyle decisions and health status. We studied the comprehension of food labels among 120 young adults (mean age 24.1 years) attending an international travel immunization clinic.

The impact of additional pertussis vaccine doses on disease incidence in children and infants.

Background: Pertussis remains a cause of considerable morbidity in children worldwide. Due to the resurgence of the disease, two vaccine doses for schoolchildren were added to the routine Israeli schedule. In 2005 a 5th dose was introduced for second-graders (aged 7-8), and in 2008 an additional catch-up dose in the eighth grade (13-14 year-olds).

Salmonella enterica outbreak in a banqueting hall in Jerusalem: the unseen hand of the epidemiological triangle?

Background: Foodborne Salmonella enterica outbreaks constitute both a threat to public health and an economic burden worldwide.

Objectives: To characterize the pathogen(s) involved and possible source of infection of an outbreak of acute gastroenteritis in a banqueting hall in Jerusalem.

Methods: We conducted interviews of guests and employees of the banqueting hall, and analyzed food items, samples from work surfaces and stool cultures.

A total of 161 cases of cutaneous leishmaniasis caused by Leishmania tropica occurred in the Jerusalem district during 2004-2005; 127 (79%) cases were in a town just outside Jerusalem. Environmental models suggest that in the context of global warming, this outbreak has the potential to extend into Jerusalem.
