Insights

Respiratory Syncytial Virus (RSV) epidemiology in Israel shifted significantly post-2008, with both RSV A and B types co-circulating. RSV infections were also delayed by the 2009 H1N1 pandemic.

Area of Science:

  • Virology
  • Epidemiology
  • Public Health

Background:

  • Respiratory Syncytial Virus (RSV) is a primary cause of infant lower respiratory tract infections.
  • Characterizing RSV epidemiology is crucial for understanding disease burden and informing public health strategies.

Observation:

  • This study analyzed RSV A and B distribution in 11,018 hospitalized patients in Israel from 2005-2012.
  • Pre-2008, a single dominant RSV type circulated annually.
  • Post-2008, both RSV A and B co-circulated significantly, especially in infants aged 0-2 years.

Findings:

  • Significant shifts in circulating RSV A and B subtypes were observed since 2008.
  • The emergence of the H1N1pdm09 influenza virus in 2009 coincided with a delay in RSV infections.
  • RSV infections occurred primarily after H1N1pdm09 circulation declined.

Implications:

  • The changing RSV epidemiology necessitates updated surveillance and intervention strategies.
  • Understanding viral interference, like that observed with H1N1pdm09, is vital for predicting respiratory illness patterns.
  • These findings contribute to the global understanding of RSV dynamics and co-infections.

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.

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,...

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...

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...

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:
