Summary
This summary is machine-generated.The COVID-19 pandemic reduced respiratory syncytial virus (RSV) hospitalizations despite increased reported cases. Post-pandemic, older children were more affected, highlighting the need to protect infants from severe RSV illness.
Area Of Science
- Pediatrics
- Infectious Diseases
- Epidemiology
Background
- The COVID-19 pandemic significantly impacted respiratory tract infections, including respiratory syncytial virus (RSV).
- Understanding the post-pandemic epidemiology of RSV is crucial for public health strategies.
Purpose Of The Study
- To investigate the changes in RSV hospitalizations and severe lower respiratory tract infections (LRTIs) in Fukushima Prefecture before and after the COVID-19 pandemic.
- To analyze the age distribution and disease burden of RSV infection in pediatric populations.
Main Methods
- A 10-year retrospective study (2014-2023) of pediatric inpatient facilities in Fukushima Prefecture.
- Collected data on RSV hospitalizations, severe LRTIs requiring respiratory support, and sentinel RSV reports.
- Compared pre-pandemic (2014-2019) and post-pandemic (2021-2023) periods.
Main Results
- Sentinel RSV reports per 10,000 children under 5 increased post-pandemic (611 vs. 445).
- RSV hospitalizations decreased (175 to 104), as did severe RSV-related LRTIs (59 to 43).
- Higher hospitalization rates were observed in children under 1 year; post-pandemic sentinel reports showed an older age distribution.
Conclusions
- Despite increased RSV surveillance reports, hospitalizations decreased post-pandemic, primarily due to a shift in the age of infected children.
- The findings underscore the critical importance of preventing initial RSV infections in infants under 1 year.
- Targeted prevention strategies for high-risk infants are essential to mitigate severe RSV outcomes.

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...
The hosts' susceptibility to infection depends on several factors. The integrity of the skin and mucous membranes helps protect the body against microbial attacks. When the skin is altered, the chance of infection, limb loss, and even death increases.
The integrity and count of the white blood cells help the body resist pathogens and fight infection. When impaired, it reduces the body's resistance to pathogens. The acidic pH levels of the gastrointestinal, genitourinary tracts, and skin...
Overview
Vaccination is the administration of antigenic material from pathogens to confer immunity against a specific microorganism. Vaccination primes the immune system to recognize and mount an immune response faster and more effectively if the real pathogen is encountered. Vaccinations are one of the most efficient ways to protect both individual humans and the general public from disease. A growing anti-vaccination skepticism risks the successes of vaccination programs that helped reduce...
Nursing management of pneumonia involves promoting airway patency, facilitating rest and conserving energy, encouraging fluid intake, maintaining nutrition, and educating patients.
The nurse must practice strict medical asepsis and adhere to infection control guidelines to minimize healthcare-associated infections.
Enhance airway patency
Position the patient correctly to facilitate drainage of the affected lung segments. Manual or mechanical percussion and vibration can also be employed....
In the ever-evolving field of public health, statistical analysis serves as a cornerstone for understanding and managing disease outbreaks. By leveraging various statistical tools, health professionals can predict potential outbreaks, analyze ongoing situations, and devise effective responses to mitigate impact. For that to happen, there are a few possible stages of the analysis:
Predicting Outbreaks
Predictive analytics, a branch of statistics, uses historical data, algorithmic models, and...
When a person's physical, emotional, intellectual, social development or spiritual functioning is compromised, this deviation from a healthy normal state is called illness. Illness creates stress that in turn harms individuals. Irritation, anger, denial, hopelessness, and fear are behavioral and emotional changes an individual experiences in the phases of illness. A variety of factors influence a person's health and well-being.
For instance, risk factors are connected to illness,...
