Geneva, Jul 2: The World Health Organization (WHO) has estimated the overall number of coronavirus cases globally at 10,357,662, with 508,055 people having died from the disease.

The UN health agency said in the situation report published on late Wednesday that 163,939 new cases had been recorded in the past day, while further 4,188 patients had died.

Americas continue to lead the count with over 5.2 million cases, followed by Europe with more than 2.7 million.

The WHO declared the COVID-19 outbreak a pandemic on March 11.

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.

Seoul, Apr 15: Wearing masks and gloves, South Korean voters cast their ballots on Wednesday to elect 300 parliamentary lawmakers amid the coronavirus outbreak.

Voting kicked off at 6 am (local time) and was to run until 6 pm (local time) at 14,330 polling stations across the country, according to the National Election Commission (NEC). The number of eligible voters is 44 million, according to Yonhap news agency.

The once-in-four-years legislative election is widely seen as a referendum on President Moon Jae-in, whose five-year term will end in mid-2022, as well as a test of the country's fight against COVID-19 under the leadership of Moon, The Strait Times reported.

South Korea has received international praise for its massive testing capability and other innovative measures, such as drive-through testing and high-tech contact tracing.

Experts, therefore, expect the ruling Democratic Party (DP) to extend its lead in Parliament, given that the government's handling of the virus outbreak is viewed positively both at home and abroad, as per The Strait Times.

At least 10,564 people in the country have been infected by coronavirus, which has claimed 222 lives. About 2,800 patients are undergoing treatment.

The number of new cases has fallen from a high of 813 on February 29 to below 50 for six days in a row as an intensive social distancing campaign that started on March 21 remained in place.

Several surveys cited by the newspaper also showed that voters consider the pandemic as the biggest factor in their decision. A recent poll showed that 72.6 per cent of respondents rated the government's response to the outbreak as positive.

The NEC has said that public safety at polling stations will be a priority to prevent any possible spread of the virus.

All 14,330 polling stations and 251 counting stations will be disinfected on polling day, the NEC was quoted.

Voters will undergo temperature screening and those registering temperatures of 37.5 degrees Celsius or higher or display respiratory symptoms will have to exercise their franchise at a separate booth.

Tuesday was the last of 13 days of campaigning, which saw most candidates reducing their ground activities and face-to-face encounters with voters. Instead, the candidates boosted their online presence with videos and social media engagements in a bid to win votes, according to The Strait Times.

In addition, the government has also decided to temporarily lift quarantine rules to permit self-isolators to vote in the elections. Some 50,000 people in self-isolation who have no symptoms and expressed a willingness to vote will be allowed to cast ballots after the regular voting ends in the evening.
