As of the latest update by the Greek authorities, the total number of confirmed Covid-19 diagnosed cases in Greece 3,252,248. 46 new deaths were reported raising the total number to 28,701. The number of patients treated in intensive care units is currently 298. 10,005 new cases were announced yesterday in Greece. 4,148 of the new cases were found in the Attica region and 1,095 new cases in the Thessaloniki region.
The number of new Covid-19 infections jumped to 10,005 on Tuesday, following 3,868 cases on Monday, the National Organization for Public Health (EODY) said.
EODY said 46 people died from Covid on Tuesday, a drop from 63 the previous day. Data also showed that the number of intubated patients saw a drop with 298, compared with 307 on Monday.
The Health Ministry said it will hold an additional briefing on the course of the pandemic at 11.30 a.m. on Wednesday, in view of the Orthodox Easter recess.
A second Global Covid-19 Summit will be held virtually next month for countries to discuss efforts to end the pandemic and prepare for future health threats, according to a joint statement on Monday.
“The emergence and spread of new variants, like Omicron, have reinforced the need for a strategy aimed at controlling Covid-19 worldwide,” the White House said in a news release with the Group of Seven and Group of 20 nations.
The announcement comes amid a surge of Covid-19 cases in parts of the United States and around the world prompted by easily transmissible variants of the virus.
China’s most populous city, Shanghai, is trying to return to normal after a nearly three-week shutdown, which, along with wider China curbs, are taking a toll on the world’s No 2 economy.
The summit will build on efforts and commitments made at the first global summit in September, including getting more people vaccinated, sending tests and treatments to highest-risk populations, expanding protections to health care workers and generating financing for pandemic preparedness, the statement said.
“We know we must prepare now to build, sustain, and finance the global capacity we need, not only for emerging COVID-19 variants, but also future health crises,” it said.
Unvaccinated people infected with the Omicron variant are unlikely to develop immune responses that will protect them against other variants of the coronavirus, a new study suggests.
Unlike antibodies induced by Covid-19 vaccines or infections with earlier SARS-CoV-2 variants, antibodies induced by the Omicron BA.1 and BA.2 variants do not neutralize other versions of the virus, researchers found when they analyzed blood samples obtained after Omicron infection.
People with Omicron “breakthrough” infections after three doses of the mRNA vaccines designed to neutralize earlier versions of the virus had high levels of neutralizing antibodies against the two Omicron variants, although the efficiency was lower than against previous SARS-CoV-2 versions, according to a report undergoing peer review at Nature Portfolio and posted on Research Square.
But among those whose immune systems had not been primed to recognize the virus through vaccination or by natural infection, antibodies after Omicron infection “were very specific for the respective Omicron variant, and we detected almost no neutralizing antibodies targeting non-Omicron virus strains,” said Karin Stiasny and Judity Aberle of the Medical University of Vienna, Austria in a joint email.
BA.2-induced antibodies appeared to be particularly unlikely to defend against any other variant, they added. The study “emphasizes the importance of booster vaccinations for immune protection.”
