World leaders ‘stand' with Britain after London attack

Islamabad, Jun 6: Pakistan has reported a record 97 COVID-19 deaths in a single day, taking the total number of fatalities to 1,935, while the number of confirmed cases in the country approached 94,000 after over 4,700 infections were detected, the health ministry said on Saturday.

Punjab registered 35,308 COVID-19 cases, Sindh 34,889, Khyber-Pakhtunkhwa 12,459, Balochistan 5,776 Islamabad 4,323, Gilgit-Baltistan 897 and Pakistan-occupied Kashmir 331 cases, the Ministry of National Health Services said.

The total number of COVID-19 cases reached 93,983 after 4,734 new infections were detected across the country, it said.

With a record 97 fatalities in one day, the death toll in the country has reached 1,935, while 32,581 people have recovered from the disease.

The ministry said that the total number of active COVID-19 cases in Pakistan are 59,467, out of which 1,265 patients are in critical condition.

More than 100 labs in the country have so far conducted 660,508 tests, including 22,185 in the last 24 hours.

There are 747 hospitals across the country with COVID-19 treatment facilities where 5,060 patients are being treated. Others have been asked to self-isolate at home.

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.

Washington, Jul 7: President Donald Trump on Tuesday formally started the withdrawal of the United States from the World Health Organization, making good on threats to deprive the UN body of its top funding source over its response to the coronavirus.

Public health advocates and Trump's political opponents voiced outrage at the departure from the Geneva-based body, which leads the global fight on maladies from polio to measles to mental health -- as well as Covid-19, at a time when cases have again been rising around the world.

After threatening to suspend the $400 million (Dh1.47 billion) in annual US contributions and then announcing a withdrawal, the Trump administration has formally sent a notice to UN Secretary-General Antonio Guterres, a State Department spokesperson said.

The withdrawal is effective in one year -- July 6, 2021 -- and Joe Biden, Trump's presumptive Democratic opponent, is virtually certain to stop it and stay in the WHO if he wins the November election.

A spokesman for Guterres and the global health body itself confirmed that the United States, a key founding WHO member, gave its notice.

In a speech earlier in the day, WHO chief Tedros Adhanom Ghebreyesus said of Covid-19, "National unity and global solidarity are more important than ever to defeat a common enemy."

In line with conditions set when the WHO was set up in 1948, the United States can leave within one year but must meet its remaining assessed financial obligations, the UN spokesman said.

'Total control'

In late May, Trump said that China exerted "total control" over the WHO and accused the UN body led by Tedros, an Ethiopian doctor and diplomat, of failing to implement reforms.

Blaming China for the coronavirus, Trump, a frequent critic of the UN, said the United States would redirect funding "to other worldwide and deserving, urgent, global public health needs."

Democratic lawmakers have accused Trump of seeking to deflect criticism from his handling of the pandemic in the United States, which has suffered by far the highest death toll of any nation despite the president's stated hope that the virus will disappear.

"To call Trump's response to Covid chaotic and incoherent doesn't do it justice," said Senator Robert Menendez, the top Democrat on the Foreign Relations Committee.

"This won't protect American lives or interests -- it leaves Americans sick and America alone," he wrote on Twitter.

Representative Ami Bera, himself a physician, said that the United States and World Health Organization had worked "hand in hand" to eradicate smallpox and nearly defeat polio.

"Our cases are increasing," Bera said of Covid-19. "If the WHO is to blame: why has the US been left behind while many countries from South Korea to New Zealand to Vietnam to Germany return to normal?"

Even some of Trump's Republican allies had voiced hope that he was exerting pressure rather than making a final decision to abandon the World Health Organization.

The investigative news outlet ProPublica reported last month that most of Trump's aides were blindsided by the WHO withdrawal announcement, which he made during an appearance about China. 

The Trump administration has said that the WHO ignored early signs of human-to-human transmission in China, including warnings from Taiwan -- which, due to Beijing's pressure, is not part of the UN body.

While many public health advocates share some criticism of the WHO, they question what other options the world body had other than to work with China, where Covid-19 was first detected late last year in the city of Wuhan.

The anti-poverty campaign ONE said the United States should work to reform, not abandon, the WHO.

"Withdrawing from the World Health Organization amidst an unprecedented global pandemic is an astounding action that puts the safety of all Americans the world at risk," it said.
