Covid-19 live updates: Delhi reports 77 new coronavirus cases and 2 more deaths

A small randomised experiment in individuals with post-COVID syndrome discovered that hyperbaric oxygen therapy improves the heart's capacity to contract normally. The research is presented at EACVI 2023, a scientific congress of the European Society of Cardiology (ESC). "The study suggests that hyperbaric oxygen therapy can be beneficial in patients with long COVID," said study author Professor Marina Leitman of the Sackler School of Medicine, Tel Aviv University and Shamir Medical Centre, Be'er Ya'akov, Israel. "We used a sensitive measure of cardiac function which is not routinely performed in all centres. More studies are needed to determine which patients will benefit the most, but it may be that all long COVID patients should have an assessment of global longitudinal strain and be offered hyperbaric oxygen therapy if heart function is reduced."

Mumbai on Wednesday reported 47 new Covid-19 cases, taking the overall tally to 11,63,399, while no fresh death linked to the infection was reported in the city, the Brihanmumbai Municipal Corporation (BMC) said.

A state of emergency was first declared in the United States in January 2020, more than three years ago.Authorities have spent months preparing for its eventual May 11 end. Covid vaccines and treatments, such as anti-viral drug Paxlovid, will mostly remain covered under public and private health insurance plans after the emergency ends, though policies for reimbursing test purchases vary. Other anti-Covid health measures were wrapped up this month as well, including vaccine requirements for US officials and foreign visitors arriving by air.

Talks on raising the US federal government's $31.4 trillion debt ceiling enter a new phase on Wednesday, after Democratic President Joe Biden and top congressional Republican Kevin McCarthy's first negotiating meeting in three months. Biden signaled an openness to Republicans' demand to claw back some unused money for COVID relief, which is less than $80 billion. House of Representatives Speaker McCarthy told reporters that Biden also indicated a willingness to work on speeding up permitting for energy projects, a goal that went unmet in 2022.

Scientists have developed a new laser-based breathalyser test powered by artificial intelligence (AI) that they say can detect Covid-19 in real-time with excellent accuracy. The team from the University of Colorado (CU) Boulder in the US hopes that the frequency comb breathalyser—essentially using laser light to distinguish one molecule from another—could revolutionise medical diagnostics.

Mexico has declared an end to the Covid-19 health emergency in keeping with World Health Organization (WHO) guidelines, Undersecretary of Prevention and Health Promotion Hugo Lopez-Gatell said.

At 21,406, the active cases comprise 0.05 per cent of the total infections. The national Covid-19 recovery rate was recorded at 98.77 per cent, the ministry said.

India has recorded 2,109 fresh Covid-19 infections, while the number of active cases have come down to 21,406 from 22,742, according to the Union Health Ministry data on Wednesday. The Covid-19 tally now stands at 4.49 crore (4,49,74,909).

The disruptions caused by the pandemic have revealed deep flaws in our supply chain for physical goods. Certain market failures that had been festering for years were suddenly exposed. But long before Covid-19 arrived, various forms of childcare, daycare, eldercare and healthcare had already seen costs explode and services unevenly distributed, even as those working in the care economy remained poorly compensated.

A primary school teacher in the Puranpur area here has been caught submitting a fake Covid-19 positive medical certificate to get exempted from polling duty in the upcoming municipal elections, an official said.

The United States is girding for the arrival of thousands of migrants this week, with the expiry of pandemic-era rules that have made claiming asylum at the border all-but impossible. The country's deep divisions over immigration are expected to be laid bare as a wave of people try to get a foothold in a place founded on the promise of safety and shelter, but where a rising tide of nationalism makes the welcome uncertain.

Fresh cases of Covid-19 continued to fall steeply for the second week running with numbers dropping to less than half of the previous week’s tally, indicating that the surge in infections was waning across the country. Deaths from the virus and other key indicators too were on the decline.

Speaking to ANI, Dr Rakesh Mishra said, "Corona is already in the endemic stage. The level of infection we saw recently from Bengaluru data was more significant than the third wave and would have had a big problem. However, it did not happen because of vaccination, or hybrid immunity. Clinically, the virus is more infectious, but clinically less harmful as it affects the body like the common cold."
