Coronavirus: Vorbeugende Maßnahmen zur Verhinderung einer Infizierung mit COVID-19 im Gesundheitswesen

Ecolab Healthcare Infection Control Precautions for 2019-nCoV

Human coronaviruses1 are common throughout the world. Human coronaviruses commonly cause mild to moderate illness. Zwei neuere, menschliche Coronaviren, MERS-CoV and SARS-CoV, verursachen bekanntermaßen schwere Erkrankungen. A novel coronavirus, SARS-CoV-2, which causes a respiratory infection called COVID-19, emerged in 2019.  Chinese authorities identified the new coronavirus originating in Wuhan, China.  Since its emergence, this virus has resulted in hundreds of thousands of confirmed cases globally.  On March 11, 2020, the World Health Organization declared the situation a pandemic because the disease has spread over many countries and continents and affects a large percent of the population.  In the United States, the Centers for Disease Control and Prevention (CDC) is working closely with state health departments and healthcare facilities on disease testing, surveillance, contact tracing, and interim guidance for clinicians on identifying, containing and treating COVID-19 infections.

What is COVID-19?2

  • Zu den Anzeichen und Symptomen zählen Fieber und leichte Atembeschwerden (z. B. Husten und Atemnot).
  • Viele Patienten aus Wuhan hatten darauf hingewiesen, dass sie einen großen Fisch- und Tiermarkt besucht hatten, sodass angenommen wird, dass das Virus von Tieren auf Menschen übertragen wurde. However, as the outbreak has evolved, community person-to-person spread is occurring. The situation with COVID-19 is evolving rapidly. While severe illness has been reported globally, other patients have had milder illness requiring no medical care. Person-to-person transmission has been reported in healthcare workers.
  • People of all ages can be infected by COVID-19. Older people, and people with pre-existing medical conditions (such as asthma, diabetes, heart disease) appear to be more vulnerable to becoming severely ill with the virus.

What are the healthcare infection control precautions for COVID-19 as it relates to hand hygiene and environmental hygiene?3

Although the transmission dynamics have yet to be fully determined, CDC currently recommends a cautious approach to patients under investigation for COVID-19:

  • Bei diesen entscheidenden Schutzmaßnahmen sind vor allem eine sorgfältige Händehygiene und Flächendesinfektion zu nennen.
  • Mitarbeiter im Gesundheitswesen sollten vor und nach jedem Patientenkontakt, der Berührung potenziell infektiöser Materialien und vor und nach der Nutzung von PPE wie Handschuhen eine angemessene Händehygiene sicherstellen. Nutzen Sie bei sichtbar schmutzigen Händen zuerst Wasser und Seife und anschließend ein Händedesinfektionsmittel auf Alkoholbasis.
  • Gesundheitseinrichtungen sollten sicherstellen, dass überall Möglichkeiten zur Händehygiene zur Verfügung stehen.
  • Healthcare professionals must be cleared, trained and fit tested for respiratory protection device use, and educated, trained and have practiced appropriate PPE use including correct use to prevent contamination of skin, clothing or the environment, prior to caring for a patient with known or suspected cases of COVID-19.
  • Das Patientenzimmer betretende Mitarbeiter sollten standardmäßige Maßnahmen ergreifen, um sich gegen Infizierungen durch Kontakt und die Luft schützen, beispielsweise indem sie einen Augenschutz (z. B. Schutzbrillen und einen Gesichtsschutz) tragen. In situations where N95 respirators are in short supply, healthcare professionals may wear surgical masks for patient contact except in instances where aerosol-generating procedures are being performed, where an N95 must be worn.
  • The EPA and the CDC recognize environmental surfaces as a vector for transmission of coronaviruses. The CDC has developed a hospital preparedness checklist4 which recommends that hospitals assess the effectiveness of environmental cleaning and consider providing refresher training on environmental hygiene best practices as outlined in the CDC Toolkit: Options for Evaluating Environmental Cleaning.5
  • Die CDC verpflichtet Gesundheitseinrichtungen dazu, Mitarbeitern eine berufs- oder aufgabenspezifische Bildung und Trainings zur Übertragung von Infektionen zur Verfügung zu stellen, einschließlich Trainings, um Kenntnisse aufzufrischen.
  • Standardmäßige Reinigung und Desinfektion sind effektive Maßnahmen zum Schutz vor dem COVID-19 im Gesundheitswesen, einschließlich bei der Behandlung von Patienten mit Aerosol.

What hand hygiene products are effective against COVID-19?

Das häufige Waschen der Hände mit Wasser und Seife ist eine der besten Möglichkeiten, die Übertragung aufkommender Krankheitserreger zu vermeiden. The World Health Organization recommends performing hand hygiene with soap and water or alcohol-based hand rub if soap and water are not available. The US Food and Drug Administration regulates claims on both medicated, antimicrobial soaps and on alcohol-based hand sanitizers. Claims related to efficacy against viruses are not allowed on any medicated, antimicrobial soaps nor on any alcohol-based hand sanitizers in the United States.

What disinfectants are effective against COVID-19?

COVID-19 is caused by SARS-CoV-2. The EPA has developed the “Guidance to Registrants: Process for making claims against emerging viral pathogens not on EPA-registered disinfectant labels”.6 This document provides general guidance to disinfectant manufacturers and addresses public concerns on a process that can be used to identify effective disinfectants for use against emerging viral pathogens. It permits manufacturers to make limited claims about their product’s efficacy against such pathogens once the EPA confirms the product meets the eligibility criteria outlined in the guidance.  In addition, the EPA has published List N: Disinfectants for Use Against SARS-CoV-2.7  See graphic below which shows how to know if a product is approved for use against COVID-19.

In addition, the table below lists Ecolab products that meet the criteria for claims against emerging viral pathogens and therefore can be used against COVID-19 when used in accordance with the directions for use against the listed supporting virus on hard, non-porous surfaces.

DAZO™ fluorescent marker is an objective method to evaluate the thoroughness of the cleaning process, rather than the presence of organic material or pathogens.5 Other environmental monitoring methods intended to measure organic load (e.g. ATP)6 or bacterial burden (e.g. bacterial cultures) do not detect viruses. Even with the best EVS staff in the world, without an effective environmental hygiene monitoring tool such as DAZO fluorescent marker, there is no way to determine the effectiveness of their cleaning practices.
