Three separate teams of scientists on two continents have found that Omicron infections more often result in mild illness than earlier variants of the coronavirus, offering hope that the current surge may not be quite as catastrophic as feared despite skyrocketing caseloads.

The researchers examined Omicron’s course through populations in South Africa, Scotland and England. The results in each setting, while still preliminary, all suggested that the variant was less likely to send people in hospitals.

“Given that this is everywhere and given that it’s going to be so transmissible, anything that would lower severity is going to be better,” said Natalie Dean, a biostatistician at Emory University in Atlanta.
