Twelve scientists from the Bonn Institute of virologists Hendrik Streeck took the opportunity to a German Corona-Hotspot to conduct their study, the virus load in quarantine households. The result is published now on the Preprint Server medrxiv.org with the remark that it is unverified results that have not yet been reviewed by other scientists.

Gangelt The Covid-19-outbreak in the district of Heinsberg, to the municipality, had recognized the Bonn virologist Streeck at an early stage as an ideal scenario to investigate Sars-CoV-2 in a everyday environment. Known to be the "Heinsberg-study" that calculated, among other things, a high level of immunity dark figure for Germany was, by a dispute among virologists. Both the high as well as the hasty publication and the public presentation prior to Easter have been criticized.

Now, a Team led by Hendrik Streeck and Ricarda Schmit published Hausen a further study in this research context: the virus emergence in air, waste water, and on surfaces of quarantine households. In 21 randomly selected households in which at least one Infected person lived, the researchers took 119 swabs of doorknobs, remote controls, pieces of furniture, 66 samples from waste water from showers, sinks and toilets, as well as 15 indoor air samples.

corona viruses in the quarantine budget: in the shower water, not in the air
The samples were tested by PCR-Test on the genome of the Coronavirus. The viral load in the home environment was surprisingly low, although, of the 43 tested adults 26 Sars-Cov-2-were positive:
most viruses, the expiry was the end of water from showers and sinks : Approximately 20 percent of Tests were positive.
The Toilet water was in ten percent of the samples virus-loaded.
the tested surfaces had only a little more than three percent of the genome of Sars-CoV-2: two doorknobs, remote control, and a wooden cover plate.
The low Numbers confirm the finding that the smear plays by the touch of objects of a subordinate role in the spread of the new Coronavirus. Neither food nor clothes, or plants were found in the quarantine-house to keep the pathogens.
the air in The room brought only negative results. This is astounding because the risk of Infection by aerosols in closed spaces as a particularly high applies. The air samples were taken with special devices, which were placed in the middle of the most frequently used area. There was not an exchange of air by an air conditioning system. From the study it is not clear why all of the air samples viruses were free.

Whether or not the detected viruses were contagious, were not able to find out, the researchers. The attempt to Sars-CoV-2 from the samples in the laboratory to breed, succeeded in a single case. But this would not necessarily mean that the virus could no longer be infectious.
the study results, the researchers see as a confirmation of the fact that hand hygiene after contact with sewage is of great importance. In addition, it is useful to close when flushing the toilet lid – not only, but especially, if someone in a household lives with a positive impact on the new Coronavirus Tested.
