Study Shows Link Between a Virus and Croup
A New Virus Called NL63 Could Be a Cause of Croup and Other Coughs
A Pattern Established
Previous studies have reported certain trends in croup, including:
- Boys are more susceptible
- Occurs most frequently in the second year of life
- Usually occurs in winter and early spring
Each of these factors is matched by patterns of the new virus' occurrence.
With an overall incidence of 5%, it is the third most frequent cause in this group of patients, they write.
"In conclusion, HCoV-NL63 infections occur frequently in young children with LRTI [lower respiratory tract infection] and show a strong association with croup, suggesting a causal relationship," van der Hoek writes.
