The findings, published in JAMA Network Open, showed that only 44 per cent of participants with newly positive SARS-CoV-2 antibodies had awareness of being infected with the virus. The majority (56 per cent) were unaware of any recent Covid-19 infection.

According to a new study, the latest Omicron sub-variants -- including the BA.4 and BA.5 which are causing new global surges in infections -- are even better at eluding vaccines and most antibody treatments than previous variants. Sub-variants BA.2.12.1, BA.4, and BA.5 are rapidly expanding worldwide, with BA.4/5 now making up more than 50 per cent of new Covid cases in the US.

On COVID-19, globally reported cases have increased nearly 30 per cent over the past two weeks. Four out of six of the WHO sub-regions saw cases increase in the last week, Ghebreyesus said at a press briefing Wednesday.

Subvariants BA.2.12.1, BA.4, and BA.5 are rapidly expanding worldwide, with BA.4/5 now making up more than 50 per cent of new Covid cases in the US.

According to the the ICMR study, administering of Covaxin booster dose will enhance the vaccine effectiveness against the Delta variant infection and give protection against the Omicron variants BA.1.1 and BA.2.

BA.4 made up 5.4 per cent of the new cases, while BA.5 made up 7.6 per cent, according to CDC estimates.

The genome sequencing body further said that the contact tracing of the BA.4 and BA.5 patients is being undertaken as a precautionary measure.

The outbreak forced leader Kim Jong Un to wear a mask in public likely for the first time since the start of the pandemic, but the scale of transmissions inside North Korea wasn't immediately known. A failure to slow infections could have serious consequences because the country has a poor health care system and its 26 million people are believed to be mostly unvaccinated. Some experts say the North, by its rare admission of an outbreak, may be seeking outside aid.

New Zealand is currently under the orange settings of the Covid-19 Protection Framework, where there is no limit for gatherings.

While existing vaccination can still reduce the risk of severe Covid disease, the variants can evade many of the neutralising antibodies that are the immune system's front line of defence.

NSW Health reported that the state's first case of BA.4 was a traveller who returned from South Africa, reports Xinhua news agency.

The team explained that SARS-CoV-2 can cause severe paediatric disease, including acute Covid-19 and multisystem inflammatory syndrome. Published reports associating SARS-CoV-2 with upper airway infection, such as laryngotracheobronchitis (croup), have been limited to small case series.

A massive crowd was seen at a three-day flea market festival at the JLN Stadium here that ended on Sunday. Very few people were seen wearing mask at the venue. The visuals from the festival have been widely shared on social media.
