University of Oxford researchers have claimed that a cheap and widely available drug called dexamethasone can help save the lives of patients who are seriously ill with coronavirus.

Scientists working on the Recovery Trial found the drug could help patients on ventilators and oxygen, but had no effect on those who did not need help breathing.

“Based on these results, one death would be prevented by treatment of around eight ventilated patients or around 25 patients requiring oxygen alone,” researchers said in a statement.

Matt Hancock, the health secretary, tweeted: “This global first exemplifies the power of science.”

“I’m absolutely delighted that today we can announce the first successful clinical trial for a treatment for Covid-19,” Mr Hancock said.

Recovery Trial experts said a randomised group of 2,104 patients was given 6mg of dexamethasone per day for 10 days, while another group of 4,321 were given normal treatment.

Dexamethasone reduced deaths by one-fifth in patients on oxygen feeds and by one-third in those who needed a ventilator to breathe, preliminary results showed.

Mr Hancock added: “This is a huge step forward and it’s because we’ve backed the science.”

Martin Landray, professor of medicine and epidemiology at the Nuffield Department of Population Health, University of Oxford, and one of the trial’s chief investigators, said in a statement: “These preliminary results from the Recovery Trial are very clear – dexamethasone reduces the risk of death among patients with severe respiratory complications.

“Covid-19 is a global disease – it is fantastic that the first treatment demonstrated to reduce mortality is one that is instantly available and affordable worldwide.”

Bengaluru, Mar 4: With the number of Coronavirus positive cases in India increasing, health department officials in Karnataka are working round the clock to keep citizens safe.

But citizens are already panicking with 97 people in Bengaluru rushing to the government-run Rajiv Gandhi Institute for Chest Diseases (RGICD) on Tuesday with symptoms matching the coronavirus.

Karnataka Chief Minister BS Yediyurappa has now appealed for calm saying there is no coronavirus in the state.

"There is a difference in what appears in the media and what is on the ground. No need to panic. PM Modi is also looking into this. My health minister addressed the media and no one needs to panic. We are ready to tackle the situation," he added.

Dr. Nagaraj, director of RGICD, said the screening process began at the hospital on January 22 and they would see some 15-20 patients and take 5-6 swabs.

"Because of apprehensions, we saw 978 patients and took 27 swabs. We have also admitted 4 patients in the isolation ward," he added.

As of today, there are 5 patients admitted in the isolation ward of RGICD. Two came in close contact with the infected techie in Telengana and three foreign nationals from Japan, Saudi Arabia, and Iran.

It says that the associate was advised to receive necessary screening and observation as mandated by the Karnataka State Health Department. The associate was screened by an authorized medical agency and determined to be asymptomatic.
