Rising COVID-19 cases in California highlight risks of delta variant, as WHO chief warns world in dangerous time of pandemic – .

A 17% increase in cases of illness transmitted by the coronavirus COVID-19 in California over the past 14 days has heightened concerns about the highly infectious delta variant of the virus, which is expected to become the dominant strain in the United States over the course of the year. time, as it has in many other places.

California averages nearly 1,000 cases per day, and Los Angeles County has previously recommended residents resume wearing face masks indoors after finding that about half of new cases were caused by the disease. delta variant, the Associated Press reported.

This variant, which was first identified in India in December, now accounts for nearly half of COVID-19 cases in some regions and a quarter of all cases in the United States, based on samples from viruses that have been sequenced, according to comments made Thursday. by Dr Rochelle Walensky, director of the Centers for Disease Control and Prevention.

Most new infections are in unvaccinated people, underscoring the protection offered by vaccines that have been granted emergency use approval in the United States. adult population by July 4.

Among adults aged 18 and over, 57.7% are fully vaccinated, with 66.7% having received at least one jab, or just 3.3 percentage points compared to the target set two months ago by the President Joe Biden. But vaccination rates vary widely from state to state, and at least 1,000 counties, mostly in the Southeast and Midwest, have vaccination rates below 30%, as reported by Jaimy Lee. from MarketWatch.

“In some of these regions, we are already seeing increased rates of disease,” Walensky said.

There was positive news for those concerned that the Johnson & Johnson vaccine did not protect against the delta variant as well as mRNA vaccines. J&J said blood samples from eight people participating in the Phase 3 clinical trial demonstrated that the shot provided neutralizing antibody activity against delta. The full dataset has not yet been released.

Prior to this announcement, the only data supporting J&J’s shot were inferred, based on what is known about the AstraZeneca vaccine, which uses similar technology.

Elsewhere, the head of the World Health Organization has again warned that the delta variant puts the world in a “very dangerous time” of the pandemic. Dr Tedros Adhanom Ghebreyesus told a briefing that the delta variant is now found in 98 countries and “is spreading rapidly”.

His warning comes as India’s official death toll has surpassed 400,000, though that number is widely seen as grossly underestimated given the state of its healthcare system. Russia, Indonesia and Thailand have all set new daily fatalities, and Japan has said it may not allow spectators at the Olympics from this month.

The UK has seen the number of delta cases quadruple in less than a month, according to Public Health England, and in Ireland vaccines will be made available to 18-34 year olds to slow the spread of the delta variant, which accounts for about 70% of cases.

Portugal is imposing a nighttime curfew in Lisbon, the Guardian reported, and in other parts of the country.

Australia is halving the number of international fights it will allow, as it struggles to contain clusters that have forced four cities to close.
