Common exposure to STL polyomavirus during childhood

Area of Science:

• Virology
• Epidemiology
• Public Health

Background:

• STL polyomavirus (STLPyV) is a recently identified virus found in human specimens.
• Understanding the prevalence and transmission patterns of novel viruses is crucial for public health.

Purpose of the Study:

• To determine the seropositivity rate of STL polyomavirus in human populations.
• To investigate the age distribution of STLPyV infection.

Main Methods:

• Development of an enzyme-linked immunosorbent assay (ELISA) for STLPyV antibody detection.
• Screening of human serum samples from Denver, Colorado (n=500) and St. Louis, Missouri (n=419).

Main Results:

• Overall seropositivity for STLPyV ranged from 68% to 70% across both study locations.
• Age-stratified analysis indicated a higher prevalence in younger age groups, suggesting childhood acquisition.

Conclusions:

• STL polyomavirus infection is widespread in the studied US populations.
• The findings suggest that STLPyV is commonly acquired during childhood, highlighting its endemic nature.
