COVID-19 Delta Variant Likely To Worsen Pandemic's Intensity; Research
SARS-CoV-2 variation with properties comparable to the Delta variant might trigger a more severe pandemic with more breakthrough infections/reinfections than variants with either trait alone, according to a study published in Journal Cell. The Delta variant has increased transmissibility and the capacity to infect those who have already been infected or vaccinated. "This can lead to an increase in the severity of the COVID disease", said a researcher.
