Coronaviruses occur in humans but also in numerous mammals and birds. In humans they cause gastro-intestinal diseases and flu-like illnesses up to pneumonia. Coronaviruses are enveloped lipid-containing viruses.
Coronaviruses include the SARS virus, which caused epidemics in 2003, and MERS-CoV, which led to 38 deaths in the Middle East in 2012/13.
More than 358 million Covid-19 cases have been confirmed worldwide since December 2019. The WHO speaks of a pandemic.
Studies show that infectious virus can be isolated from the throat and lungs. No infectious viruses are detected in stool, urine and blood. This confirms the assumption that the main transmission routes are droplet infections and aerosol transmissions. Transmissions via contaminated objects (smear infections) play a minor role, since they were not yet confirmed beyond the health care sector.
Thus, personal hygiene rules, wearing a proper face mask, regular room ventilation and keeping a minimum distance of 1,5 meters (5 feet) to other persons are appropriate actions to reduce the prevalence of SARS-CoV-2 virus. Besides, hand and surface disinfection are the most important disinfection measures.

Hygiene tips for preventing infection in everyday life (e.g. with coronaviruses, cold viruses or flu viruses):
Wash your hands with soap for 20 to 30 seconds many times each day.
Avoid touching the mucous membranes of your mouth, nose and eyes.
Keep your distance from other people when coughing.
Ideally, cough and sneeze into the crook of your elbow.
Always use disposable tissues, then dispose of them and wash your hands immediately afterwards.
Ventilate rooms for around ten minutes three to four times every day.
Refrain from shaking hands, hugging and kissing people as you greet them.

When using the products, at least the application conditions for activity against enveloped viruses must be selected!
Treatment of dishes and cutlery does not require any alterations. They can be cleaned as usual with temperatures above 60 °C, since SARS-CoV-2 virus is relatively sensitive to high temperatures. An additional measure could be transportation of the wash ware to the dish washer in closed containers.
