What does the commercial lab data say about parvovirus B19 detection rates recently?
Recent commercial lab data indicates that human parvovirus B19 detection rates have gone up. In 2024, there were more positive test results than in the years 2018 through 2019 1. This trend continued into early 2025, where labs found more specimens with B19 antibodies between January and May 2025 compared to the same time in 2024 3.
What the research says
A report from commercial labs highlights a clear increase in positive human parvovirus B19 test results in 2024 when compared to the 2018-2019 period 1. This suggests the virus is being detected more frequently in recent years.
Specific attention has been paid to certain groups, such as pregnant persons in Minnesota, where field reports note an increase in infection frequency 2.
The upward trend appears to be ongoing. Data from early 2025 shows that the number of blood samples positive for B19 antibodies rose during January through May 2025 compared to the same months in 2024 3.
