Omicron causes more reinfections but symptoms less severe, says scientist
Scientist studying outbreak of new Covid-19 variant warns of a higher rate of repeat infections
Katharine Houreld and Ayenat MersiePicture: 123RF/PERIG76SA is seeing an increase in Covid-19 reinfections due to the Omicron variant but symptoms for reinfected patients and those infected after vaccination appear to be mild, a scientist studying the outbreak of the new strain say.
The new variant, which has caused global fears of a surge in infections, was first detected in Southern Africa and is fast overtaking Delta to become the dominant variant in SA, where case numbers are rising dramatically.“Previous infection used to protect against Delta but now with Omicron that doesn’t seem to be the case,” said Anne von Gottberg, microbiologist at SA’s National Institute for Communicable Diseases.
She told an online news conference hosted by the World Health Organization (WHO) that she and her colleagues believed reinfections with Omicron and breakthrough infections in vaccinated patients would feature less severe symptoms.Von Gottberg said the travel bans imposed by many countries on passengers from SA were having an adverse effect on the logistics of scientific research into Omicron. headtopics.com
“There are fewer flights to choose from to bring in reagents, to bring in equipment, in addition to send out specimens and isolates for people to be able to then work with Omicron,” she said.Isolates are cultures of micro-organisms isolated for study.
African leaders have complained about the travel restrictions, saying their countries were being penalised for their transparency in reporting data on the new variant.More than 50% of African nations can now do the genomic sequencing to identify the variant, the WHO said, and those that cannot are partnered with nations that can.
WHO officials told the same event Covid-19 vaccination was improving in Africa, with five countries including SA now having vaccinated more than 40% of their populations, though coverage remained low elsewhere.At a separate online news conference, the head of the
Africa Centres for Disease Control and Prevention, Dr John Nkengasong, said supplies of vaccines to the continent had improved.“Vaccines are beginning to flow to the continent in a very predictable and steady manner,” he said, adding that the challenge now was to ensure those supplies were used, in a context where vaccine hesitancy remains high. headtopics.com
“The uptake is not as we would have loved to see,” he said.Some African countries had delayed the deliveries of vaccines, including those of doses provided under the AU’s African vaccine acquisition task team, he said.Read more: Business Day »

Lift travel bans, Omicron has ‘probably already spread globally’, say top SA scientistsBy their nature‚ Sars-CoV-2 variants are several steps ahead of the international travel curve and travel bans are pointless, say scientists
Omicron had 'probably already spread globally', say top SA scientists as they slam travel bansTop SA scientists slam the global travel bans, saying they were not only ineffective but did significantly more harm than good. I wonder why they have not slammed masks and lockdowns and natural immunity. Strange hey. I of course the travelbans are now a pesky inconvenience to them 🤡🤡🤡🤡 Fully Agree! The sad part bayogcina ngokukhuluma nje.nothing can change that.they're afraid of Europe

Omicron spreads like wildfire | CitypressOmicron spreads like wildfire | Preliminary information from around the world suggests that Omicron is significantly more contagious than its Sars-CoV-2 predecessors, but perhaps also less fatal If it’s in US already why close of South Africa Omicron is not as severe as feared by expert 🤔 But you left out the juicy part
WHO says no Omicron deaths yet, as variant spreads worldwideThe US and Australia became the latest countries to confirm locally transmitted cases of the variant, as Omicron infections pushed SA's total cases past three million. Tell WHO to go fuck themselves. Gee I wonder why 🙄 Manje Laba balana ekhaya bona bathi cha kuyafiwa umkhroni ,ibaphi abafayo Kanti yo
