Diverse clinical manifestations of Parvovirus B19 infections during the 2024 outbreak in Germany.

What it found
Each row is one number read from the abstract, on the scale the paper reported it, with its interval. Left of the dashed line favours the treatment, right favours the comparator. Under each row is the sentence it came from. New to these charts? A ten-minute tutorial.
The abstract states no effect estimate the extractor could read, or names no intervention and outcome on the map, so this paper lights no cell and moves no belief. It is still indexed, cited and linked below.
The trial behind it
Trials whose registry record cites this paper, or whose number appears in the abstract. A trial that started after this paper was published is citing it as background, not reporting it.
Neither the registry nor the abstract names a trial number. If this is a trial report, that itself is worth knowing.

Abstract
purposeIn 2024, human parvovirus B19 (PB19V) infections have increased in Germany and globally. It is an infection associated with a broad spectrum of clinical manifestations. To raise awareness, we present representative cases and virological data from different specialties across three German university hospitals.
methodsFollowing a nationwide survey by the AGIHO in March 2024 indicating increased PB19V infections, we conducted a retrospective, multi-center descriptive study across Munich, Cologne, and Magdeburg. Anonymized clinical and virological data from 2022 to 2024 were collected, including patient demographics, underlying diseases, and diagnostic findings. Acute PB19V infection was defined by real-time quantitative PCR-based detection of PB19V DNA in any specimen.
resultsClinical manifestations of acute PB19V infections can range from severe anemia and pancytopenia in hematologic patients, to fetal hydrops in pregnant women, and systemic inflammatory symptoms in patients with chronic conditions. In 2024, the Max von Pettenkofer Institute in Munich conducted 936 PB19V PCR tests. A marked increase in positive cases was observed in early 2024, with positivity rates of 16% in Q1 and 18.2% in Q2, compared to an annual positivity rate of 2.3% in 2023. Similar trends were seen at the University Hospitals Cologne and Magdeburg. Most infections were acute with high viral loads. Most cases originated from pediatric, gynecologic, and hematologic departments, highlighting particularly vulnerable patient populations.
conclusionsThis resurgence in symptomatic PB19V infections, likely driven by pandemic-related shifts in immunity and exposure, underscores the need for heightened clinical awareness, early testing in high-risk populations, and sustained surveillance to anticipate future outbreaks.
