Purpose of review Mass gathering events bring people from across all continents increasing the risk of spread of aerosol transmissible respiratory tract infections. Respiratory tract infections for instance in pilgrims attending the world's largest recurring annual pilgrimage, the Hajj are common. We review recent literature on viral and bacterial infectious diseases with special focus on the Hajj. Recent findings The prevalence of bacterial and viral infections continue to increase, because of the acquisition of rhinovirus, coronaviruses (229E, HKU1, OC43), influenza A H1N1, Streptococcus pneumoniae, Haemophilus infl...

Purpose of review This manuscript reviews the recent literature related to new developments in the understanding of existing and novel virulence factors of the pneumococcus that are of potential importance in the development of novel preventive and therapeutic strategies. Recent findings The pneumococcal capsule and pneumolysin have long been recognized as being two of the most prominent virulence factors, with much recent research having revealed previously unrecognized mechanisms by which they contribute to the pathogenesis of infection. Although the pneumococcal capsule has been considered a sine qua non for virule...

ConclusionsHigher frequency of hematopoietic malignancy in CVID than in the other PADs and association of lower NK cell counts with non-infectious complications in CVID suggest a relationship between immune alterations and the development of non-infectious manifestations in PADs.

Abstract BACKGROUND: Otitis is a frequently occurring condition in young children and involves considerable use of antibiotics. The most common bacterial cause is pneumococci. The pneumococcal vaccine was introduced as part of the Childhood Immunisation Programme in Norway in 2006. The purpose of the study was to investigate whether this vaccination may have reduced the number of otitis cases presenting at emergency primary health care units. MATERIAL AND METHOD: The material consists of data from all electronic reimbursement claims from emergency primary health care doctors in the period 2006-18. Annual cons...

Pneumococcal disease is characterized by diverse clinical manifestations, but the overall burden is dominated by pneumonia which accounted for 15% of all pediatric deaths in 2017 (World Health Organization, 2019). Furthermore, up to 81% of pneumonia deaths occur in the first two years of life and nearly all pneumonia deaths are recorded in low- and middle-income countries, with Sub-Saharan Africa bearing a great share of pneumonia burden (43% of global pneumonia deaths)(Walker et al., 2013). In 2016, pneumonia was the third most frequent cause of visit to hospital outpatient clinics in Burkina Faso, representing 5 ·...

In this study, we report the impact of the pneumococcal conjugate vaccine (PCV), PCV7/PCV13 sequential implementation on serotype distribution, and on the prevalence of piliated strains among carried pneumococci during the pre- and post-vaccine eras. METHODS: During 2002-2016, 12 repeated cross-sectional surveillances of nasopharyngeal S. pneumoniae carriage were conducted among 8,473 children

, SIREVA II Group Abstract Streptococcus pneumoniae is a major cause of morbidity and mortality worldwide, especially among children and the elderly. S. pneumoniae serotype 19A has emerged as a major cause of invasive disease in many countries, regardless of whether pneumococcal conjugate vaccines are used. The aim of this study was molecular characterization of invasive S. pneumoniae serotype 19A isolates recovered between 2000 and 2015 from 13 National Laboratories through the laboratory-based surveillance of invasive S. pneumoniae program SIREVA II in Latin American countries. The isolates were submitted with a...
