ROME, Italy — The new Covid variant Omicron has many more mutations than the Delta variant, according to a first "image" of this new variant initially detected in South Africa, produced and published by the prestigious Bambino Gesu hospital in Rome.

On the three-dimensional "image", which looks like a map, "we can clearly see that the Omicron variant presents many more mutations than the Delta variant, concentrated above all in one area of the protein that interacts with human cells", the team of researchers said in a statement Sunday.

"This does not automatically mean that these variations are more dangerous, just that the virus has further adapted to the human species by generating another variant," the researchers said.

"Other studies will tell us if this adaptation is neutral, less dangerous or more dangerous," they added.

The research team focused on the search for mutations in "the three-dimensional structure of the spike protein", Claudia Alteri, professor of clinical microbiology at Milan State University and a researcher at Bambino Gesu, told AFP.

The image was produced "from the study of the sequences of this new variant made available to the scientific community" coming mainly "from Botswana, South Africa and Hong Kong".

"This image, which represents a map of all the variations, describes the mutations of Omicron but does not define its role," she said.

"It will now be important to define through laboratory experiments whether the combination of these mutations can have an impact on transmission or on the effectiveness of vaccines, for example," she added.

The Philippines reports the detection of 492 additional cases of the hyper-transmissible Omicron variant of COVID-19.

Of the total, 332 are locals, while 160 are returning overseas Filipinos.

This brings the total number of Omicron cases in the country. — Gaea Katreena Cabico

France's daily reported new coronavirus cases broke a new record on Tuesday with an average of over 300,000 a day in the past week, with the headline figure approaching half a million.

The latest data issued by Public Health France showed that there were 464,769 new cases in the last 24-hour period as the Omicron variant of Covid-19 spread unabated.

A day earlier, 102,144 people had tested positive for the virus. — AFP

China's postal service has ordered workers to disinfect international deliveries and urged the public to reduce orders from overseas after authorities claimed mail could be the source of recent coronavirus outbreaks.

China Post on Monday published a statement ordering workers to disinfect the outer packaging of all international mail "as soon as possible" and requiring employees handling foreign letters and packages to receive booster vaccine shots.

The postal service also asked the public to reduce purchases and deliveries from "countries and regions with a high overseas epidemic risk" and said domestic mail should be handled in different areas to prevent cross-contamination. — AFP

Preliminary data from a trial shows AstraZeneca's COVID-19 vaccine increased antibodies against the coronavirus Omicron variant for a booster dose.

The British-Swedish pharmaceutical reports that the response against both Omicron and Delta variants was seen in those who received the booster while initially vaccinated with either the AstraZeneca shot or another mRNA vaccine.

Omicron is now the dominant COVID-19 variant in the Philippines says Health Secretary Francisco Duque III, citing results of the latest genome sequencing on January 3.

The newest "variant of concern" has surpassed the Delta variant, believed to be behind the second wave of the pandemic in March last year.

Omicron is even more transmissible than the Delta variant.
