Diphtheria, pertussis, and tetanus are potentially deadly bacterial infections that are largely preventable through vaccination, though they remain in the population. This issue reviews the epidemiology, pathophysiology, diagnosis, and current recommended emergency management of these conditions. Disease-specific medications, as well as treatment of the secondary complications, are examined in light of the best current evidence. Resources include obtaining diphtheria antitoxin from the United States Centers for Disease Control and Prevention and best-practice recommendations with regard to testing, involvement of government health agencies, isolation of the patient, and identification and treatment of close contacts...

In the United Kingdom, pertussis guidance recommends prophylaxis for household contacts within 21 days of case symptom onset if the household includes a vulnerable contact. The aim of our study was to identify characteristics associated with cases reported late for public health action. We reviewed the epidemiology of cases reported in London and South East England for the period 2010 to 2015. We characterised risk factors associated with late reporting of cases and described public health actions taken on timely reported cases...

Pertussis is most severe among unvaccinated infants (< 1 year of age), and still leads to several reported deaths in the Netherlands every year. In order to avoid pertussis-related infant morbidity and mortality, pertussis surveillance data are used to guide pertussis control measures. However, more insight into the accuracy of pertussis surveillance and control, and into the range of healthcare and public health-related factors that impede this are needed. We analysed a unique combination of data sources from one Dutch region of 1...

Whooping cough, or pertussis, is a contagious disease of the respiratory tract that is re-emerging worldwide despite high vaccination coverage. The causative agent of this disease is the Gram-negative Bordetella pertussis. Knowledge on complement evasion strategies of this pathogen is limited. However, this is of great importance for future vaccine development as it has become apparent that a novel pertussis vaccine is needed. Here, we unravel the effect of Virulence associated gene 8 (Vag8) of B. pertussis on the human complement system at the molecular level...

Humans are often colonized by polymorphic bacteria such as Streptococcus pneumoniae, Bordetella pertussis, Staphylococcus Aureus, and Haemophilus influenzae. Two co-colonizing pathogen clones may interact with each other upon host entry and during within-host dynamics, ranging from competition to facilitation. Here we examine the significance of these exploitation strategies for bacterial spread and persistence in host populations. We model SIS epidemiological dynamics to capture the global behavior of such multi-strain systems, focusing on different parameters of single and dual colonization...

PURPOSE: The purpose of the study was to describe the patterns of use of universally recommended adolescent vaccines in the United States. METHODS: We identified 11-year-olds using the MarketScan insurance claims database (2009-2014). Human papillomavirus (HPV), tetanus-diphtheria-acellular pertussis (Tdap), and meningococcal (MenACWY) vaccination claims were identified using diagnosis and procedure codes. Generalized linear models estimated vaccination incidence rates and correlates of adolescent vaccination and timely vaccination...

BACKGROUND: Pertussis in young infants is a unique, severe, afebrile, cough illness that is frequently fatal. METHODS: All pertussis cases ≤ 120 days of age admitted to a pediatric intensive care unit (PICU) in California between October 1, 2013 and April 25, 2015 were evaluated. RESULTS: Of 100 pertussis patients ≤ 120 days of age admitted to PICU's, there were 5 deaths. The white blood cell (WBC) counts in the fatal cases were significantly higher than in the non-fatal cases...

In the Republic of Ireland, the schedule of state-funded immunisation for children is comprehensive and includes diphtheria, pertussis, tetanus, pneumococcus, hepatitis B, meningococcus C, haemophilus B, polio, measles, rubella and mumps. Varicella and meningococcal B vaccines are commercially available but are not currently funded by the government. Each of the illnesses preventable by these vaccines can cause substantial morbidity, and rarely mortality, in infants and children. Our PICU continues to see serious illness due to avoidable infection...

Whooping cough is an immune preventable disease that can be life threatening. Despite infant immunization starting at 2 month of age, there are many cases and outbreaks in our country and also around the world, with a high risk of mortality specially in infants under 6 month of age. It has been proposed that antenatal vaccination with acellular pertussis component (Tdap) would be useful, safe and effective since it transfers a high antibody rate to the child, reducing the incidence of pertussis in this group by 85%...

This report provides an epidemiological description of selected vaccine-preventable diseases in New South Wales (NSW), Australia, for 2014 to inform ongoing disease monitoring and control efforts. A trend of increasing pertussis notifications was observed, beginning midway through 2014 with the highest disease rates in the 5-9 year age group. Measles notifications increased to 67 cases in 2014 from 34 cases in 2013. Measles cases were associated with travel-related importations-predominantly from the Philippines-and secondary transmission increased compared to 2013 involving three main disease clusters...

REVIEW
Thomas C Mitchell, Carolyn R Casella
Development of non-infectious subunit vaccines is hampered by a slow pipeline of new adjuvants to replace or enhance alum in part because expectations of safety are high. Transient vaccine side effects are not clinical priorities because they cause no lasting harm and vaccine development has appropriately been focused on avoidance of serious adverse events. As a result, surprisingly little is known about the extent to which side effects caused by a vaccine's reactogencicity are predictive of successful immunization outcomes...

BACKGROUND: In Germany, pertussis became notifiable in eastern federal states in 2002 and nationwide in March 2013. Infants are at greatest risk for severe disease, with a high proportion requiring hospitalization. We implemented enhanced hospital-based surveillance to estimate the incidence of pertussis requiring hospitalization among infants in Germany and to determine the proportion of infants hospitalized with pertussis too young to have been vaccinated. METHODS: Enhanced surveillance was implemented within a nationwide hospital surveillance network (ESPED)...

The surveillance of infectious diseases is of great importance for disease control and prevention, and more attention should be paid to the Class B notifiable diseases in China. Meanwhile, according to the International Monetary Fund (IMF), the annual growth of Chinese gross domestic product (GDP) would decelerate below 7% after many years of soaring. Under such circumstances, this study aimed to answer what will happen to the incidence rates of infectious diseases in China if Chinese GDP growth remained below 7% in the next five years...

BACKGROUND/PURPOSE: Although assessing the immunogenicity and protective efficacy of acellular pertussis (aP) vaccines via murine model studies faces limitations, preliminary assessments have been achieved by evaluating respiratory challenge and humoral and cellular immunity. METHODS: We performed a long-term intranasal respiratory challenge with reference and clinically isolated strains of Bordetella pertussis. Simultaneously, we assessed humoral and cellular immunity for evaluating the immunogenicity of a newly developed tri-component diphtheria-tetanus-aP (DTaP) vaccine...

BACKGROUND: The Millennium Development Goals (MDGs) are 8 international development goals voluntarily adopted by 189 nations. The goals included health related aims to reduce the under-five child mortality rate by two-thirds (MDG4), and to reduce the maternal mortality ratio by three-quarters (MDG5). To assess the relationship between the healthcare workforce and MDGs 4-5, we examined the physician workforces of countries around the globe, in terms of the Physician Density Level (PDL, or number of physicians per 1000 population), and compared this rate across a number of years to several indicator variables specified as markers of progress towards MDG4 and MDG5...

BACKGROUND: Hexavalent diphtheria (D)-tetanus (T)-acellular pertussis (aP)-inactivated poliovirus (IPV)-hepatitis B (HB)-Haemophilus influenzae type b (PRP-T)-containing vaccines are increasingly the standard of care. This study evaluated the primary series (NCT01177722) and booster (NCT01444781) of a fully liquid DTaP-IPV-HB-PRP-T vaccine in Latin America. METHODS: Infants (N=1375) received HB vaccine at birth and were randomized to one of three batches of the investigational DTaP-IPV-HB-PRP-T or licensed control vaccine (DTaP-HB-IPV//PRP-T) at 2-4-6 months of age, co-administered with 7-valent pneumococcal conjugate vaccine (PCV7) (2-4-6 months) and rotavirus vaccine (2-4 months)...

The Gram-negative bacterium Bordetella pertussis is the causative agent of whooping cough, a serious respiratory infection causing hundreds of thousands of deaths annually worldwide. There are effective vaccines, but their production requires growing large quantities of B. pertussis. Unfortunately, B. pertussis has relatively slow growth in culture, with low biomass yields and variable growth characteristics. B. pertussis also requires a relatively expensive growth medium. We present a new, curated flux balance analysis-based model of B...
