Islamabad, Jun 3: Pakistan has reported a record 4,132 fresh cases of the coronavirus in the last 24 hours, taking the total number of infections to 80,463, the health ministry said on Wednesday.

The Ministry of National Health and Services said the new infections were detected after conducting a maximum of 17,370 tests in a day.

Of the total cases, Sindh has so far detected 31,086 patients of the coronavirus, Punjab 29,489, Khyber-Pakhtunkhwa 10,897, Balochistan 4,747, Islamabad 3,188, Gilgit-Baltistan 779 and Pakistan-occupied Kashmir reported 289 patients of the viral disease.

"In total 67 patients died in the last 24 hours, taking the tally of deaths to 1,688. Another 28,923 people have fully recovered from the disease," the ministry said in a statement.

The authorities have so far carried out 595,344 tests in the country.

Officials said that Pakistan has more than 100 labs that can conduct over 30,000 tests per day and the number of daily tests will be gradually increased to the maximum level.

Melbourne, Apr 10: Scientists have identified six drug candidates from more than 10,000 compounds that may help treat COVID-19.

The research, published in the journal Nature, tested the efficacy of approved drugs, drug candidates in clinical trials and other compounds.

"Currently there are no targeted therapeutics or effective treatment options for COVID-19," said Professor Luke Guddat from the University of Queensland in Australia.

"In order to rapidly discover lead compounds for clinical use, we initiated a programme of high-throughput drug screening, both in laboratories and also using the latest computer software to predict how different drugs bind to the virus," Guddat said.

The project targeted the main COVID-19 virus enzyme, known as the main protease or Mpro, which plays a pivotal role in mediating viral replication, the researchers said.

This makes it an attractive drug target for this virus, and as people don't naturally have this enzyme, compounds that target it are likely to have low toxicity, they said.

"We add the drugs directly to the enzyme or to cell cultures growing the virus and assess how much of each compound is required to stop the enzyme from working or to kill the virus. If the amount is small, then we have a promising compound for further studies," said Guddat.

After assaying thousands of drugs, researchers found of the six that appear to be effective in inhibiting the enzyme, one is of particular interest.

"We're particularly looking at several leads that have been subjected to clinical trials including for the prevention and treatment of various disorders such as cardiovascular diseases, arthritis, stroke, atherosclerosis and cancer," Guddat said.

Researchers said compounds that are already along the pipeline to drug discovery are preferred, as they can be further tested as antivirals at an accelerated rate compared to new drug leads that would have to go through this process from scratch.

"With continued and up-scaled efforts we are optimistic that new candidates can enter the COVID-19 drug discovery pipeline in the near future," Guddat said.

Rome, Mar 21: Italy on Friday reported a record 627 new deaths from the novel coronavirus, taking its overall toll past 4,000 as the pandemic gathered pace despite government efforts to halt its spread.

The total number of deaths was 4,032, with the number of infections reaching 47,021.

Italy's previous one-day record death toll was 475 on Wednesday.

The nation of 60 million now accounts for 36.6 percent of the world's coronavirus deaths.

Italy has seen more than 1,500 deaths from COVID-19 in the past three days alone.

Its current daily death rate is higher than that officially reported by China at the peak of its outbreak around Wuhan's Hubei province.
