The spread of Omicron, coupled with enhanced testing and low vaccination rates may have played a role, it added.
The Omicron variant has been reported in 57 nations and the number of patients needing hospitalisation is likely to rise as it spreads, the World Health Organization said on Wednesday.
The WHO, in its weekly epidemiological report, said more data was needed to assess the severity of disease caused by the Omicron variant and whether its mutations might reduce protection from vaccine-derived immunity.
"Even if the severity is equal or potentially even lower than for Delta variant, it is expected that hospitalisations will increase if more people become infected and that there will be a time lag between an increase in the incidence of cases and an increase in the incidence of deaths," it said.
On November 26, the WHO declared the Omicron variant, which was first detected in southern Africa, a variant of concern. It is the fifth SARS-CoV-2 strain to carry such a designation.
