Today, infectious diseases are the second leading cause of death globally, surpassed only by heart diseases. Traditionally, the most common strategies to mitigate disease-causing agents' spread are based on chemical disinfect...

New study tests how mutations in SARS-CoV-2 affect antibody neutralization Using pseudoviruses with single amino acid substitutions, researchers found that mutations in severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) reduce monoclonal antibody neutralization differently. However, convalescent sera samples did not lose neutralization potency many and were also effective against the B.1.1.7 (UK-derived) strain. As SARS-CoV-2 continues to infect people around the world, it is also mutating. The majority of the mutations are on the virus spike protein, the key viral component that bi...

SARS-CoV-2 can infect blood monocytes and trigger inflammation, finds study Researchers found about 10% of blood monocytes in coronavirus disease 2019 (COVID-19) patients are infected with severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2). These monocytes then die, leading to the release of cytokines – a feature associated with severe and critical COVID-19. In some COVID-19 patients, SARS-CoV-2 infection can lead to acute respiratory distress and multi-organ failure and death. Severe disease has been associated with increased pro-inflammatory cytokines and C-reactive protein. Mye...

Researchers have found a new SARS-CoV-2 variant in California, USA. This variant is more transmissible than circulating strains but slightly less transmissible than the new N501Y variant and moderately resistant to antibodies in convalescent sera and mRNA vaccines.

Although the researchers found that the rats tested negative for the virus, they say it is important to continue monitoring animals for the virus as it mutates, making previously resistant species susceptible to infection.
