Launch of the BSC website: ‘www.bode-science- centre.com ’ as a knowledge portal for all questions relating to disinfection and infection protection (with pathogen search, concentration calculator, articles on hygiene measures and current topics, etc.) eLearning programmes on hand hygiene: Learning important measures in a playful way Placing a peripheral venous catheter (only when indicated) Position patient Open sterile package of the catheter Disinfect hands Select insertion site (preferably back of the hand and forearm) , compress vain and palpate Disinfect the skin (pay attention to exposure time!) Afterwards, do not palpate puncture site (unless aseptic technique is maintained) Put on gloves Disinfect hands Puncture vein and insert catheter Remove tourniquet and needle Aseptically connect sterile plug / infusion Apply sterile dressing to puncture site and fix Remove gloves Disinfect hands Disinfect contact surfaces Pay particular attention to these critical moments to prevent infections. 1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 Example checklist.

Coronaviruses belong to the family of Coronaviridae . These enveloped viruses may cause respiratory tract infections, such as colds, bronchitis or pneumonia and gastrointestinal infections. In December 2019, several cases of pneumonia caused by a novel coronavirus (SARS-CoV-2) were reported in Wuhan City (China). The disease is called Coronavirus disease 2019 (COVID 19). Further important representatives within the family of Coronaviridae are: SARS-CoV (Severe Acute Respiratory Syndrome coronavirus) and MERS-CoV (Middle East Respiratory Syndrome coronavirus). Hygiene measures can considerably reduce the risk of infection with coronaviruses. One crucial element of infection prevention is a consequent basic hygiene including hand disinfection and surface disinfection. What symptoms does a SARS-CoV-2 infection have? The symptoms of an infection with SARS-CoV-2 can vary but often include often fever and dry cough. Most infections are mild to moderate. However, there are also severe and life-threatening courses of disease with pneumonia up to acute lung failure. Severe courses of the disease usually occur in elderly and previously ill persons. Which disinfectants can be used? For the inactivation of coronaviruses such as SARS-CoV, MERS-CoV and SARS-CoV-2, disinfectants that are at least virucidal against enveloped viruses should be used. HARTMANN disinfection products for hands (Sterillium range), skin, surface (Bacillol range, Kohrsolin range, Mikrobac range, Dismozon range) and instruments (Bomix plus, Korsolex range) fulfil the requirements and can be used. What are the paths of infection? Transmission path Carrier Droplet Airborne droplets that are produced during infection speaking, sneezing or coughing can be transported short distances and by this reach other persons´ respiratory tracts and mucous membranes. Direct Transmission via hands, e.g. of patients or transmission medical and nursing staff Indirect When touching contaminated transmission surfaces, e.g. bedside tables, bedframes, stethoscopes, etc., the hands can be contaminated with virus particles which can then be transmitted to other persons. 2012 SOPs for PVC - from research to practice: Development of SOPs with hygiene-relevant steps for the placement of a peripheral venous catheter (PVK); applied in a joint study with multimodal intervention at the Univer- sity Medical Centre Hamburg-Eppendorf.[1,2] 2013 Reprocessing of wipe dispensers for surface disinfection: Collection and examination of contaminated wipe dispensers; develop- ment and publication of a new set of reprocessing guidelines.
