Brief an die Politik

Wir sind über den aktuellen Ansatz zur Reduzierung der Covid-19 Luftübertragung in Schulen in Deutschland besorgt und empfehlen dringend, die neuesten Richtlinien der WHO in Bezug auf Belüftung, und wo dies nicht möglich ist, betreffend mechanischer Luftreinigung, zu berücksichtigen. Darüber hinaus besteht bei uns Sorge, dass die in einigen öffentlichen Ausschreibungen genutzten Kriterien für die Anschaffung von Luftreinigungsgeräten nicht ausreichend sind und die Schulen daher das Risiko tragen, in unangemessene und nicht nachhaltig nutzbare Geräte zu investieren. Laut internationalen Studien, präsentiert durch den Biochemiker und Aerosolforscher Dr. Gerhard Scheuch in der ZDF Sendung "Markus Lanz" vom 14. April 2021, erfolgen 95% bis 99% der Infektionen mit Covid-19 in Innenräumen. Wir bitten Sie dringend, Richtlinien zu etablieren, sodass Schulen passende Geräte kaufen, welche einen relevanten Unterschied erzielen und das Übertragungsrisiko in der Luft zwischen Schülern, Lehrern, Professoren und Mitarbeitern bestmöglich reduzieren.
