Jun 13: Requiring the wearing of masks to prevent the spread of the novel coronavirus in areas at the epicenter of the global pandemic may have prevented tens of thousands of infections, a new study suggests.

Mask-wearing is even more important for preventing the virus' spread and the sometimes deadly COVID-19 illness it causes than social distancing and stay-at-home orders, researchers said, in the study published in PNAS: The Proceedings of the National Academy of Sciences of the USA.

Infection trends shifted dramatically when mask-wearing rules were implemented on April 6 in northern Italy and April 17 in New York City - at the time among the hardest hit areas of the world by the health crisis - the study found.

"This protective measure alone significantly reduced the number of infections, that is, by over 78,000 in Italy from April 6 to May 9 and over 66,000 in New York City from April 17 to May 9," researchers calculated.

When mask-wearing went into effect in New York, the daily new infection rate fell by about 3% per day, researchers said. In the rest of the country, daily new infections continued to increase.

Direct contact precautions - social distancing, quarantine and isolation, and hand sanitizing - were all in place before mask-wearing rules went into effect in Italy and New York City. But they only help minimize virus transmission by direct contact, while face covering helps prevent airborne transmission, the researchers say.

"The unique function of face covering to block atomization and inhalation of virus-bearing aerosols accounts for the significantly reduced infections," they said. That would indicate "that airborne transmission of COVID-19 represents the dominant route for infection."

The U.S. Center for Disease Control and Prevention on Friday urged organizers of large gatherings that involve "shouting, chanting or singing to strongly encourage the use of cloth face coverings to lower the risk of spreading the coronavirus."

Washington, May 19: As the scientists across the world are struggling to develop a vaccine for combating coronavirus, US drugmaker Moderna announced on Monday (local time) that the phase I trial of its Covid-19 vaccine has shown positive early results.

The company is hopeful that it's vaccine could be available to the public as early as January next year. Several firms across the world are in the race to develop a vaccine for the deadly virus which has claimed over 3 lakh lives worldwide.

CNN citing Dr. Tal Zaks, Moderna's chief medical officer reported that "if future studies go well, the company's vaccine could be available to the public as early as January".

"This is absolutely good news and news that we think many have been waiting for for quite some time," Zaks was quoted as saying.

Moderna, based in Cambridge, Massachusetts announced that the vaccine developed neutralising antibodies to the virus at levels reaching or exceeding the levels seen in people who have naturally recovered from Covid-19, reported CNN.

These will be followed by phase 2 trials and phase 3 trials, which Moderna plans to start in July.

President Donald Trump had on Friday said that that the United States will be able to deliver a few hundred million doses of COVID-19 vaccine, under 'Operation Warp Speed', by the end of this year.

"I have very recently seen early data from a clinical trial with a coronavirus vaccine and this data made me feel even more confident that we'll be able to deliver a few hundred million doses of vaccine by the end of 2020 and we will do the best we can," Trump had said at a press conference at the White House on Friday.

Jan 27: The Andhra Pradesh Cabinet passed a resolution on Monday setting in motion the process for abolishing the state Legislative Council.

A similar resolution will now be adopted in the Legislative Assembly and sent to the Centre for necessary follow-up action.

With just nine members, the ruling YSR Congress is in minority in the 58-member Legislative Council. The opposition Telugu Desam Party (TDP) has an upper hand with 28 members and the ruling party could get a majority in the House only in 2021 when a number of opposition members will retire at the end of their six-year term.

The move by the Andhra Pradesh cabinet came after the Y S Jaganmohan Reddy government last week failed to pass in the Upper House of the state legislature two crucial Bills related to its plan of having three capitals for the state.

Andhra Pradesh Legislative Council Chairman M A Sharrif on January 22 referred to a select committee the two bills -- AP Decentralisation and Inclusive Development of All Regions Bill, 2020, and the AP Capital Region Development Authority (CRDA) Act (Repeal) Bill -- for deeper examination.

The chairman had said that he was using his discretionary powers under Rule 154 while referring the Bills to the select panel in line with the demand of the TDP.

Following this, the chief minister had told the Assembly, "We need to seriously think whether we need to have such a House which appears to be functioning with only political motives. It is not mandatory to have the Council, which is our own creation, and it is only for our convenience."

"So let us discuss the issue further on Monday and take a decision on whether or not to continue the Council," he had said.

In fact, the YSRC had on December 17 first threatened to abolish the Council when it became clear that the TDP was bent on blocking two Bills related to creation of a separate Commission for SCs and conversion of all government schools into English medium.

As the Legislature was adjourned sine dine on December 17, no further action was taken. But last week, the issue cropped up again as the TDP remained firm on its stand on opposing the three-capitals plan.

The YSRC managed to get two TDP members to its side, but the government failed to get the three capitals Bills passed in the Council.

"What will be the meaning of governance if the House of Elders does not allow good decisions to be taken in the interest of people and block enactment of laws? We need to seriously think about it… Whether we should have such a House or do away with it," the chief minister had said in the Assembly.
