“May I use the biological pool?” That is the question that some owners of biological pools pose this spring.

The answer is yes, but there is still a very low water temperature. But this can change quickly as Spring advances.

People want to know what happens with the virus in the water, and it is good to ask this, now or later, in times when the virus will not be talked about so much.

Pathogenic viruses have, just like pathogenic bacteria, enough difficulties to survive outside the human body. Yes, they can withstand up to a few hours above surfaces of some materials, but these observations are results of  laboratory studies. Many pathogens face major problems of survival outside the human body and exposed to the sun because of UV radiation and other types of radiation. While humans, animals and plants have a protective structure against this radiation, such as skin, hair, scales, bark and many others, microbes are left without protection against radiation and die quickly exposed outside.
Viruses like the Corona types don’t even like being outside the human body, nor do they like the aquatic environment very much. There are few studies with viruses in biological pools, but everything indicates that they are facing the same problems as pathogenic bacteria in biological pools. They do not survive in an environment that is not theirs and where zooplankton feed on microbes of all kinds. This time also, zooplankton is a proven agent in the cleaning of water in biological pools.

Generally speaking, as long as it is respected that no sick person enters the biological pool, there is no known high risk of bathing in a biological pool. In Corona times, this assessment is also supported by the Federal Environment Agency of Germany, which recently published a recommendation on swimming pools and biological pools in times of the Corona epidemic.
