Danger! Vibrio infections: Bathing waters in Saxony-Anhalt at risk!

The sun is burning and the temperatures are rising, but with the heat the danger from harmful bacteria also increases. Current reports indicate that the risk of Vibrio infections in German waters increases significantly, especially in summer heat. That's how it puts it n-tv found that alarming cases were documented, especially in Saxony-Anhalt. The latest investigations by the State Office for Consumer Protection show that vibrios, which can lead to serious wound infections or even diarrhea, were detected in two bodies of water: in the Strandsolbad Staßfurt and in the Angersdorfer Teiche natural pool near Halle.

The likelihood of coming into contact with these dangerous bacteria is increasing. The Geo reports that vibrios multiply rapidly in surface waters at water temperatures above 20 degrees. Flat coastal areas that warm up quickly, as is the case in the Baltic Sea, are particularly affected. Open wounds and a weakened immune system significantly increase the risk of infection, which is why affected waters should be avoided.

The dangers of vibrios

There has been a worrying development in recent years: Since 2020, there has been a reporting requirement for non-cholera vibrios (NCV) in Germany. That too Robert Koch Institute (RKI) has already registered at least two infections in Germany by the beginning of July 2023. The increase in water temperatures and the associated changes in the ecosystem promote the spread of these pathogens.

The symptoms that can be caused by vibrios range from skin reactions to serious wound infections and blood poisoning (sepsis). The species Vibrio vulnificus is particularly feared because it can quickly cause tissue damage. In addition to increasing bacterial concentrations in water bodies, climate change is also encouraging the establishment of new pathogens, which further complicates the situation.

Precautions and outlook

The EU Bathing Water Directive currently does not require specific testing for vibrios in bathing water, which has sparked discussion about new regulations. Some federal states have already begun to examine water quality more closely in areas where Vibrios are often found. Despite the increasingly serious situation, the danger from vibrios does not disappear, as their occurrence is widespread in saline waters and also in slightly saline inland waters.

Climate change is making the problem worse. Not only are water temperatures rising, extreme weather events can also flush harmful viruses into our waters. A circumstance that further challenges the work of the health authorities and the vigilance of bathers.

It remains to be hoped that increased awareness and adapted measures can significantly reduce the risk to the health of the population. Anyone planning to go to the Baltic Sea or similar waters should keep an eye on the current warnings from the authorities before swimming.
