Insights

Pertussis (whooping cough) hospitalizations and deaths significantly increased in Brazilian children from 2011-2013. Infants under one year old were the most affected group, highlighting a critical public health concern.

Area of Science:

  • Pediatrics
  • Infectious Diseases
  • Public Health Epidemiology

Background:

  • Pertussis, also known as whooping cough, is a highly contagious respiratory infection.
  • Vaccination has historically reduced pertussis incidence, but outbreaks can still occur.
  • Understanding temporal trends in pertussis is crucial for public health interventions.

Purpose of the Study:

  • To analyze the trends in pertussis-related hospitalizations and deaths among Brazilian children between 1996 and 2013.
  • To identify specific age groups and geographical regions most impacted by pertussis during the study period.

Main Methods:

  • A descriptive ecological study design was employed.
  • Data on pertussis hospitalizations and deaths in children up to 19 years of age were obtained from the DATASUS database (1996-2013).
  • Descriptive statistical analyses were used to assess temporal trends.

Main Results:

  • A total of 19,047 pertussis hospitalizations and 498 deaths were recorded during the study period.
  • Infants under one year old accounted for 88.2% of hospitalizations and 96.8% of deaths.
  • A notable increase in hospitalizations and deaths occurred in the years 2011, 2012, and 2013 across all Brazilian regions, particularly in the Southeast, North, and Northeast.

Conclusions:

  • A significant surge in pertussis hospitalizations and deaths was observed in Brazilian children during 2011-2013.
  • Infants under one year represent the most vulnerable population to severe pertussis outcomes.
  • These findings underscore the need for enhanced pertussis surveillance and vaccination strategies in Brazil.

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...

Pneumonia I: Introduction01:30

Pneumonia I: Introduction

Pneumonia is an acute respiratory infection that targets the lungs, specifically the alveoli. These tiny air sacs, essential for oxygen exchange, become engorged with pus and fluid, severely hindering breathing, decreasing oxygen absorption, and causing significant pain and discomfort during respiration.
Risk Factors
Various factors influence the likelihood of developing pneumonia. Age plays a crucial role, with infants, children under two, and individuals over 65 at increased risk due to their...

Pulmonary Tuberculosis V

Medical management of tuberculosis (TB) patients involves a comprehensive approach that includes diagnosis, treatment, and monitoring. The specific strategies can vary depending on the type of tuberculosis (latent or active), the patient's overall health status, and other considerations.
Latent tuberculosis infection occurs when TB bacteria are present in a person's body, but are not causing illness or symptoms. It is not contagious, and preventive treatment is crucial to avoid the...

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.

Infectious Diseases and Their Occurrence01:28

Infectious Diseases and Their Occurrence

Infectious diseases appear in populations through various transmission patterns, influenced by pathogen characteristics, population immunity, environmental conditions, and social behavior. Understanding these patterns is essential for effective public health surveillance and intervention. These categories—sporadic, outbreak, epidemic, pandemic, and endemic—help frame the nature and scope of disease events.Sporadic diseases occur irregularly and infrequently, without a predictable...
