SARS-CoV-2 coronavirus (COVID-19)

What are coronaviruses?

Coronaviruses occur in humans and also in mammals and birds. In humans, they cause gastro-intestinal diseases and flu-like illnesses up to and including pneumonia. Coronaviruses are enveloped lipid-containing viruses. The group of coronaviruses includes the SARS virus that caused epidemics in 2003 and MERS-CoV, which resulted in 38 deaths in the Middle East in 2012/13.

The novel coronavirus, SARS-CoV-2 (COVID-19)

Multiple cases of infection with the novel coronavirus (SARS-CoV-2) had been confirmed in China, specifically in Wuhan, since December 2019. Since then, the virus has been spreading around the world. The disease triggered by SARS-CoV-2 is referred to as COVID-19 (Coronavirus Disease 2019).The symptoms most frequently mentioned are a fever, cough and sore throat. The World Health Organization (WHO) declared COVID-19 a pandemic on 11 March 2020.

Occurrence and transmission

Recent studies show that this infectious virus can be isolated from the pharynx and the lungs. No infectious viruses are detected in faeces, urine and blood. This confirms the assumption that droplet infection is the main mode of transmission. Transmission can also take place via contaminated objects (smear infection).

Hygiene tips for preventing infection in everyday life

Hygiene tips for preventing infection in everyday life (e.g. with coronaviruses, cold viruses or flu viruses):

Wash your hands and keep them away from your face

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.

Cough and sneeze hygienically

Keep your distance from other people when coughing.
Ideally, cough and sneeze into the crook of your elbow.

Blow your nose

Always use disposable tissues, then dispose of them and wash your hands immediately afterwards.

Ventilate regularly

Ventilate rooms for around ten minutes three to four times every day.

Protect yourself and others

Refrain from shaking hands, hugging and kissing people as you greet them.

Effectiveness of Dr. Weigert disinfectants against coronaviruses

According to the RKI (Robert Koch Institut), disinfectants with proven 'virucidal activity against enveloped viruses', 'limited-spectrum virucidal activity' or 'virucidal activity' are effective against coronaviruses and should be used to combat them. When using the products, you should therefore ensure that the application conditions for 'virucidal activity against enveloped viruses' are chosen as a minimum. Dr. Weigert disinfectants have been proven to be suitably effective and can therefore be used.

Disinfecting and decontaminating hands

Hand hygiene measures are among the most important infection prevention measures, because the hands are among the most frequent routes for transmitting pathogens.

For thorough hand hygiene, Dr. Weigert offers the following disinfectants:

Surface disinfection

Surface disinfection is an important measure for preventing the transmission of pathogens via surfaces that frequently come into contact with hands or skin (e.g. door handles). Besides the hands, indirect transmission of the coronavirus via contaminated surfaces in a clinical environment must also be considered according to the RKI.

For surface disinfection, Dr. Weigert offers the following disinfectants:

Instrument disinfection

The reprocessing of medical instruments plays an important part in everyday clinical routines to prevent nosocomial infections. When treating patients demonstrably infected with the coronavirus, the RKI recommends using instruments specific to the individual for direct contact (e.g. ECG electrodes, stethoscopes). Furthermore, reprocessing in accordance with the requirements of the recommendation by the Commission for Hospital Hygiene and Infection Prevention and the German Federal Institute for Drugs and Medical Devices is sufficiently effective.
