Omicron may have a higher risk of reinfection

The World Health Organization said early data indicates that Omicron, the latest variant of the SARS-CoV-2 first found in South Africa, may easily infect people who have either been infected earlier or vaccinated. But the disease will be milder than what the Delta variant led to, WHO said.

The new variant was found in the last week of November and since then it has now spread to around 57 countries. No death has been linked to this variant and patients are recovering without hospitalisation, without requiring oxygen support.
