SINGAPORE: Early clinical observations around the world suggest that the COVID-19 variant of Omicron may be more transmissible and carry a higher risk of reinfection compared to the Has delta and beta variants of the virus, the Ministry of Health (MOH) announced on Sunday (December 5). .

“This means that people who have recovered from COVID-19 are more likely to get infected again with the Omicron variant,” said the Ministry of Health in an update on the Omicron variant. </ As the new variant spreads around the world, Singapore "must expect to discover more cases at our borders and in the future in our community," added MOH.

The ministry said it had reports in recent days from South Africa and other countries and actively engaged experts in affected countries to obtain first hand information.

“This press release updates our understanding of the Omicron variant, even if many questions remain without clear answers,” said MOH. Studies on whether existing COVID-19 vaccines are effective against the new variant are ongoing, but “Scientists around the world are taking the view that existing COVID-19 vaccines are being used by Grandma cron variant will still work, especially in protecting people from serious illnesses “. “Said MOH.

The ministry urged those eligible to get vaccinated or have their booster vaccination, and said there was strong scientific consensus that this should be done before all existing and future variants of COVID- 19.

Another factor could be that existing patients who have been diagnosed with non-COVID-19 related reasons were hospitalized, could have tested positive for the variant in the hospital About the severity of the disease, “said MOH.

” The outbreak was first spotted in a university town with a younger population. According to the South African health experts, hospital stays for this population group have so far been short, around a day or two. “
