- Delta has kept some of the most successful mutations found in earlier variants, but also contains new genetic changes that enable it to spread twice as fast. Delta is more dangerous in many ways. It has an incubation period of four days, rather than six, making people contagious sooner.

Data indicate that Delta is 40-60% more transmissible than Alpha and almost twice as transmissible as the original Wuhan strain of SARS-CoV-2. Furthermore, significantly more viral particles have been found in the airways of patients infected with the Delta variant. A Chinese study reported that viral loads in Delta infections were ~1,000 times hig...
According to surveys conducted in the U.K., where Delta accounts for ~90% of current COVID-19 cases, symptoms of Delta tend to be a little different than other strains, but that does not necessarily mean the associated symptoms are more severe. Fever, headache, sore throat and runny nose are common, while cough and loss of smell are not. Other repo...
Studies show that 2 doses of vaccines are effective at preventing hospitalization and death, but neutralization levels of vaccinated sera are lower against the Delta variant compared to the original strain. A study published in the New England Journal of Medicine tested neutralization activity of serafrom individuals who had recovered from natural ...
Without a doubt, increased transmissibility, coupled with potential increases in disease severity and immune escape, makes Delta especially dangerous. The SARS-CoV-2 spike protein is the main target of COVID-19 vaccines, and most serum neutralizing antibody responses elicited during natural SARS-CoV-2 infection are directed at the receptor binding ...
Humanity has its hands full as the virus continues to mutate and evolve potential mechanisms to escape the immune defenses its hosts have worked so hard and sacrificed so much to develop. In addition to the variants of concern currently being monitored, researchers are keeping an eye on a number of variants of interest, including Lambda. When speci...

Oct 5, 2021 · These data signify that the Delta variant of SARS-CoV-2 (B.1.617.2) is more infectious than smallpox, which has an R 0 of 3.5–4.6. 22 Hence, it is crucial for people to comply with physical distancing and other precautionary measures to better take control of the infection caused by the Delta variant.
