Spanish-originated SARS-CoV-2 variant A222V shows rapid spread in Lazio, Italy

A startling new study reports the rapid rise to dominance of a new severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) strain in Italy. This strain, termed the GV clade, is characterized by a single point mutation.

New and sudden headaches may be a symptom of COVID-19

Researchers report a case of a young male patient who came in with a headache to an emergency room. He had increased intracranial pressure and tested positive for SARS-CoV-2, suggesting new headaches during the pandemic should not be ignored.

Scientists detect a sarbecovirus phylogenetically related to SARS-CoV-2 from bats in Japan

A team of researchers at the University of Tokyo in Japan have detected a sarbecovirus, called Rc-o319, which is phylogenetically positioned in the same clade as SARS-CoV-2 in Rhinolophus cornutus bats in Japan.

Particulate matter levels can play a significant role in SARS-CoV-2 transmission

A new study has found that particulate matter (PM) plays a role in providing surfaces for SARS-CoV-2 transmission and interaction, enabling fomite transmission through deposition.

SARS-CoV-2 deletion mutations may have attenuated infectivity in some strains

A team of researchers at the University of Hong Kong has identified a panel of SARS-CoV-2 variants, called Del-mut, which contains a deletion in the S1/S2 junction. Upon investigating one of the deleted variants in animal models, they found that Del-mut-1 is attenuated in its ability to cause disease or pathological changes.

Does smoking increase risk of COVID-19 hospitalization?

A study conducted by UK researchers has found that patients hospitalized with coronavirus disease 2019 (COVID-19) were less likely to be current smokers than patients who had been admitted with other types of respiratory viral infections last year (2019).
