Coronavirus infections in Germany are primarily driven by variant B117
Headline: B117 (Alpha) Variant Accounts for Over Two-Thirds of COVID-19 Cases in Germany, Posing Airborne Transmission Risks
In a recent report by the Robert Koch Institute (RKI), it has been revealed that the B117 variant, first identified in the UK, now accounts for 64% of COVID-19 infections in Germany. This alarming increase in the prevalence of the B117 variant has led to concerns about its potential for airborne transmission and the subsequent risk it poses in community and workplace settings.
According to an analysis by a lab consortium, the B117 variant was found in 72.2% of samples analyzed. This high proportion has led experts to predict an overall continued exponential increase in COVID-19 cases in Germany. The RKI report also states that the B117 variant is currently considered more infectious than other variants.
The B117 variant is noted for increased airborne transmission potential, with reports of transmission occurring beyond 2 meters, linked to higher secondary attack rates during events such as singing or in enclosed spaces with insufficient ventilation. In Germany, a documented outbreak in a meat processing plant with B117 involved 31 confirmed cases, highlighting the variant's ability to spread rapidly in indoor environments with limited air circulation.
While other variants, such as the Delta variant, are known to be more infectious, the data lacks updated quantitative transmission rates or a direct variant-to-variant transmission rate comparison specific to Germany. However, the increased airborne transmission risk associated with the B117 variant raises concerns about its potential for community spread, even in settings where distancing measures and adequate ventilation are in place.
The RKI's analysis of the 7-day incidence rates shows an exponential increase in the B117 variant since the second calendar week. This trend suggests that the B117 variant is driving the current surge in COVID-19 cases in Germany.
The search results provide limited direct data specific to the B117 variant transmission rates and concerns in Germany compared to other variants as of mid-2025. For precise current transmission rates and epidemiological surveillance data, German public health authorities such as the Robert Koch Institute would be the best source.
In light of these findings, it is crucial for individuals to continue following public health guidelines, such as wearing masks, maintaining social distancing, and ensuring adequate ventilation in indoor spaces, to mitigate the risk of COVID-19 transmission.

In the context of the concerns surrounding the B117 (Alpha) variant in Germany, it's important to note that this variant, according to recent health-and-wellness reports, is currently considered more infectious than other variants, particularly when it comes to airborne transmission risks (Other science). Furthermore, medical-conditions experts predict an overall continued exponential increase in COVID-19 cases in Germany due to the high prevalence of the B117 variant (Other science).
