Indoor air quality has an influence on how many corona virus infections occur there. This has now been shown for the first time in a pilot project involving Empa researchers in 150 primary school classrooms in Graubünden. The analysis also showed that the air quality in many classrooms is poor. The study concluded that regular ventilation of classrooms is therefore very important, even in winter months.

Like many viruses, SARS-CoV-2 relies on lipid modifications carried by host enzymes to organize their membrane structure and coordinate the function of virulence proteins. Scientists at EPFL have discovered the enzymes that transfer fatty acids to one of the main components of SARS-CoV-2, its fusion protein Spike. The findings reveal that such fatty acids are important for the production of infectious SARS-CoV-2 particles, and can help develop new drugs for treating coronaviruses and other viruses like herpes and influenza.

Scientists at Lausanne University Hospital (CHUV) and EPFL have discovered a highly potent monoclonal antibody that targets the SARS-CoV-2 spike protein and is effective at neutralizing all variants of concern identified to date, including the delta variant. Their findings are published in the prestigious journal Cell Reports.

An international collaboration with EPFL has developed a method to improve the performance of COVID-19 contact-tracing apps by taking into account a user’s recent contacts, risk levels and shared information about tests and symptoms.

EPFL has teamed up with Vaud Canton’s Office for Civil Protection and General Health Office to deploy targeted mobile COVID vaccination centers and inform high risk groups about the importance of getting vaccinated in order to stem the pandemic.
