Abstract

Insights

This study on Bordetella pertussis (whooping cough) in Saudi Arabia found most cases were in infants under six months. Older adults were also significantly affected, highlighting vulnerabilities in a highly vaccinated population.

Area of Science:

  • Infectious Diseases
  • Pediatrics
  • Epidemiology

Background:

  • Pertussis, commonly known as whooping cough, remains a significant public health concern globally.
  • Vaccination strategies aim to control pertussis transmission, but breakthrough infections can occur.
  • Understanding the epidemiology of pertussis in specific regions is crucial for targeted public health interventions.

Purpose of the Study:

  • To characterize the clinical features and demographic patterns of Bordetella pertussis infections.
  • To analyze presentation and outcomes of pertussis cases within the Saudi Aramco Medical Services Organization (SAMSO) in Saudi Arabia.
  • To identify specific age groups most affected by pertussis in this population.

Main Methods:

  • A retrospective analysis was conducted on confirmed Bordetella pertussis cases.
  • Data were collected from January 1996 to December 2004.
  • Patient demographics, vaccination status, and clinical outcomes were reviewed.

Main Results:

  • 156 confirmed cases of Bordetella pertussis were identified.
  • The majority of cases (52%) were infants under six months of age.
  • Hospitalization was required for 42% of patients, with a median stay of five days. Vaccination status varied, with a notable proportion of unvaccinated infants.

Conclusions:

  • Infants under six months and older adults represent the most affected groups for whooping cough in this Saudi Arabian cohort.
  • The findings underscore the importance of continued surveillance and vaccination efforts, particularly for vulnerable age groups.
  • Pertussis poses a risk even in populations with high vaccination coverage.

Overview
Respiratory Syncytial Virus Disease01:29

Respiratory Syncytial Virus Disease

Human respiratory syncytial virus (RSV) is a widespread pathogen that primarily targets infants and young children but also poses a serious health risk to elderly and immunocompromised individuals. Belonging to the Pneumoviridae family, RSV is a negative-sense, single-stranded RNA virus within the Pneumovirus genus. Its global health burden is significant, with millions of cases annually resulting in hospitalizations and mortality, particularly in resource-limited settings. Although most...
Inhalation Anthrax01:25

Inhalation Anthrax

Anthrax is a zoonotic disease caused by Bacillus anthracis, a Gram-positive, spore-forming bacterium. It primarily affects herbivorous animals but can be transmitted to humans through skin contact, ingestion, or inhalation of spores.Cutaneous anthrax, the most common form, typically results from direct contact with bacterial spores through skin abrasions and is generally less severe. Gastrointestinal anthrax results from eating undercooked or contaminated meat. It affects the mouth, throat, or...
Diphtheria01:28

Diphtheria

Diphtheria is an acute, toxin-mediated infectious disease that primarily affects the upper respiratory tract. It is caused by Corynebacterium diphtheriae, a Gram-positive, pleomorphic rod that lacks spore-forming capability and exhibits a characteristic club-shaped morphology under microscopic examination. While C. diphtheriae can asymptomatically colonize mucosal surfaces, clinical disease manifests only when the bacterial strain is lysogenized by a specific β-corynephage. This phage...
Smallpox01:24

Smallpox

Smallpox is a severe contagious disease caused by the Variola major virus, a double-stranded DNA member of the Poxviridae family.Variola major transmission occurs primarily via inhalation of virus-laden droplets or direct contact with infectious scabs. The incubation period averages approximately seven days, although it may range from 7 to 17 days depending on the inoculum and host factors.Clinically, the prodromal phase is marked by an abrupt onset of high fever, malaise, headache, and myalgia.
Pulmonary Tuberculosis I01:29

Pulmonary Tuberculosis I

Tuberculosis, often called TB, is a contagious illness primarily caused by Mycobacterium tuberculosis. It mainly affects the lung parenchyma but can also impact other body parts.
Causative Organism
The primary infectious agent causing tuberculosis is Mycobacterium tuberculosis, a slow-growing, acid-fast, aerobic rod that exhibits sensitivity to heat and ultraviolet light. Instances of Mycobacterium bovis and Mycobacterium avium contributing to the development of TB infection are rare.
