(RSV) accounts worldwide for more than 60% of acute respiratory infections in children and more than 80% in infants younger than 1 year and at the peak of viral season.
RSV is also a problem for SENIORS in the winter Oct 2017
- Most people contract the virus by age 2 and get it repeatedly throughout life.
- For healthy people, RSV feels like a cold.
- Its symptoms can be indistinguishable from the flu, except for the fact that RSV is less likely than the flu to cause fever.
RSV is also known as Human orthopneumovirus - Wikipedia
- " It is a major cause of lower respiratory tract infections and hospital visits during infancy and childhood."
- "In temperate climates there is an annual epidemic during the winter months; in tropical climates, infection is most common during the rainy season."
- "In the United States, 60% of infants are infected during their first HRSV season,[2] and nearly all children will have been infected with the virus by 2–3 years of age"
- RSV is an enveloped virus, similar to Coronavirus

- What is the role of vitamin D supplementation in respiratory syncytial virus (RSV) infection prevention? Feb 2019
- "neonates born with 25-OHD concentrations lower than 50 nmol/L had a 6-fold greater risk of RSV LRTI in the first year of life than neonates with 25-OHD concentrations of 75 nmol/L or less. "

Low levels of blood vitamin D have been reported in children who have frequent respiratory tract infections. We measured serum concentrations of 25-hydroxy (OH) vitamin D in Japanese infants less than 3-months old infected with respiratory syncytial virus (RSV). Serum levels of 25-OH vitamin D of the 10 infants, excluding those with underlying diseases, were between less than 4 to 29.8 ng/mL. In 8 out of 10 subjects (80.0%), serum 25-OH vitamin D levels were less than 20 ng/mL. There was no statistically significant association between levels of 25-OH vitamin D and age, duration of admission, respiratory severity score, white blood cell count, blood gas levels, and NT-proBNP levels. Levels of serum 25-OH vitamin D in children who required hospitalization owing to RSV infection were low, indicating deficiency. These results suggested that vitamin D deficiency affects the susceptibility to RSV infection, but not the severity of the RSV respiratory infection.
