Insights

Respiratory syncytial virus (RSV) infections occur year-round in Puerto Rican infants, impacting children under two. Enhanced surveillance is recommended to understand RSV epidemiology and improve immunoprophylaxis strategies.

Area of Science:

  • Pediatrics
  • Infectious Diseases
  • Virology

Background:

  • Respiratory syncytial virus (RSV) is a major cause of infant bronchiolitis and pneumonia.
  • In tropical regions, RSV infections can occur year-round.

Purpose of the Study:

  • To assess RSV infections in children under two during the 2009-2010 season in Puerto Rico.
  • To evaluate trends in positive RSV tests from 2007 to 2009.

Main Methods:

  • Retrospective data review from six hospitals in Puerto Rico.
  • Inclusion of patients with confirmed RSV bronchiolitis.

Main Results:

  • A total of 4,678 patients were analyzed, with a mean age of 7 months.
  • RSV infections were detected throughout the year during the study period.

Conclusions:

  • RSV demonstrates a year-round presence in Puerto Rico.
  • Strengthening RSV surveillance is crucial for understanding epidemiology and refining immunoprophylaxis guidelines.

Rous Sarcoma Virus (RSV) and Cancer

Rous Sarcoma virus or RSV was discovered by F. Peyton Rous in the year 1911 as a filterable transmissible agent that could cause tumors in chickens. He won a Nobel Prize for this discovery in 1966. His experiments clearly demonstrated that some cancers could be caused by infectious agents and led to the discovery of many more cancer-causing viruses in animals as well as humans.
RSV is a retrovirus that contains two copies of a plus-strand  RNA genome. Its genome consists of four main open...

Common Respiratory Disorders01:31

Common Respiratory Disorders

Respiratory disorders, a prevalent health concern globally, are generally divided into two primary categories: upper and lower respiratory tract disorders. The categorization is based on the area of the respiratory system they affect.
Upper respiratory disorders impact the airways above the vocal cords, encompassing areas like the nose, sinuses, and throat. Various conditions fall under this category, including the common cold and allergic rhinitis. These disorders can stem from several causes,...

Pulmonary Cycle: Exhalation01:17

Pulmonary Cycle: Exhalation

In terms of human respiration, the act of expelling air, known as exhalation (or expiration), operates on the principle of pressure gradients. During expiration, the pressure within the lungs exceeds that of the surrounding atmosphere. Under normal conditions, quiet breathing involves passive exhalation and is free of muscular contractions. This is because the exhalation process is driven by the natural elastic recoil of the lungs and chest wall, both of which have an inherent tendency to...

Influenza01:27

Influenza

Influenza is an acute, highly communicable viral disease that affects the respiratory tract and is responsible for seasonal epidemics worldwide. Influenza A is the most prevalent type associated with widespread outbreaks and is subtyped based on two surface glycoproteins: hemagglutinin (H) and neuraminidase (N), as in H1N1. These glycoproteins are essential for viral infectivity, transmission, and immune recognition. Transmission occurs primarily through respiratory droplets and contaminated...

Acute Respiratory Failure-II01:21

Acute Respiratory Failure-II

Type I Respiratory Failure, or hypoxemic respiratory failure, occurs when the partial pressure of oxygen (PaO2) in arterial blood falls below 60 mmHg while breathing room air without a corresponding increase in arterial carbon dioxide levels (PaCO2). This condition highlights a significant impairment in the lungs' capacity to oxygenate the blood.
The underlying physiological abnormalities that contribute to hypoxemic respiratory failure include:
