China's SARS and SARS-CoV-2 outbreak management in comparative perspective

A new study compares the current SARS-CoV-2 outbreak with the earlier SARS-CoV epidemic to understand the best way to respond to it sensitively and flexibly. This involves early detection, using multiple screening tests, followed by management of the clinical features as required, in order to prevent disease-related injury.

Self-sterilizing polymers are effective at inactivating SARS-CoV-2 virus

Researchers from North Carolina State University, Boston University, and Kraton Corporation have demonstrated a family of self-sterilizing polymers that are effective at inactivating coronaviruses, including SARS-CoV-2 - the virus that causes COVID-19.

New type of antibody marks infected cells, makes them visible to the immune system

Scientists at Cardiff University have discovered a unique way to target a common virus that affects one in 200 newborn babies in the UK but for which there is only limited treatments available.

Study shows how SARS-CoV-2 uses an immune system defense for replication

The immune system actually wants to fight SARS-CoV-2 with antiviral signaling molecules. But a research team from Charité and MDC has now shown how such a signaling molecule can promote the replication of the virus. The results have been published in the journal EMBO Molecular Medicine.

Antibody testing is key to understand immune response to SARS-CoV-2

While PCR testing has been used widely for COVID-19 diagnosis, it only provides information on who is currently infected. Antibody testing can tell who has been previously exposed to SARS-CoV-2, the virus that causes COVID-19, a metric that is essential for tracking spread across a population.
