PM Modi holds 'productive talks' with Thai counterpart

Washington, Jul 1: The United States has approved four coronavirus vaccine candidates for clinical trials, Food and Drug Administration (FDA) head Stephen Hahn told reporters.

"Four vaccines have been approved for moving into clinical trials... and another six are in the pipeline for us to review," Hahn said during a press briefing on Tuesday.

The US Administration launched in May Operation Warp Speed, a joint project of Health and Defense Departments, which aims to deliver 300 million doses of a vaccine for COVID-19 by January 2021.

The country's top pandemics expert Anthony Fauci warned on Tuesday, however, that there is no certainty the United States will be able to develop a vaccine against COVID-19 that works and will be safe.

Data on vaccine effectiveness, he added, may be available in the winter or early next year.

Islamabad, May 24: Pakistan recorded 32 coronavirus-related deaths during the last 24 hours, taking the total number of fatalities in the country to 1,133, the health ministry said on Sunday.

The total number of COVID-19 patients in Pakistan also jumped to 54,601, it said.

Sindh reported the maximum number of 21,645 coronavirus cases, followed by Punjab at 19,557, Khyber-Pakhtukhwa at 7,685, Balochistan at 3,306, Islamabad at 1,592, Gilgit-Baltistan at 619 and Pakistan-occupied Kashmir (PoK) at 197.

According to the health ministry, 17,198 coronavirus patients have recovered and 473,607 tests, including 12,915 in the last 24 hours, have been conducted so far.

The government also issued strict instructions to observe social distancing while offering Eid prayer and asked people to avoid visiting relatives and hosting parties.

Eid congregations were held at open places, mosques and Eidgahs in all major cities and towns while following strict standard operating procedures (SOPs) of social distancing and other precautionary measures.

Pakistan Prime Minister's Special Assistant on Health Zafar Mirza on Friday said the deadly infection would continue to multiply if precautions are not taken.

Earlier this month, the government had announced the lifting of the countrywide lockdown imposed to curb the spread of the virus in phases, even as infections continued to rise in the country.

Prime Minister Imran Khan had cited the economic havoc the virus restrictions had wreaked on citizens as the reason behind the decision.

The prime minister on Saturday urged Pakistanis to forgo traditional Eid festivity in view of the hundreds of fatalities caused by the coronavirus and the lives lost in Friday's plane crash in Karachi.

Ninety-seven people, including nine children, were killed and two passengers miraculously survived a fiery crash when a Pakistan International Airlines plane with 99 travellers on board plunged into a densely populated residential area near the Jinnah International Airport in Karachi. Most of the victims were travelling home to celebrate Eid.

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."
