Pak Bans 1st Class Air Travel By Leaders, Officials, Work Hours Revised

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."

Tehran, Jun 29: Iran has issued an arrest warrant and asked Interpol for help in detaining President Donald Trump and dozens of others it believes carried out the drone strike that killed a top Iranian general in Baghdad, a local prosecutor reportedly said Monday.

While Trump faces no danger of arrest, the charges underscore the heightened tensions between Iran and the United States since Trump unilaterally withdrew America from Tehran’s nuclear deal with world powers.

Tehran prosecutor Ali Alqasimehr said Trump and more than 30 others whom Iran accuses of involvement in the Jan. 3 strike that killed Gen. Qassem Soleimani in Baghdad face “murder and terrorism charges,” the semiofficial ISNA news agency reported.

Alqasimehr did not identify anyone else sought other than Trump, but stressed that Iran would continue to pursue his prosecution even after his presidency ends.

Interpol, based in Lyon, France, did not immediately respond to a request for comment.

Alqasimehr also was quoted as saying that Iran requested a “red notice” be put out for Trump and the others, which represents the highest level arrest request issued by Interpol. Local authorities end up making the arrests on behalf of the country that request it. The notices cannot force countries to arrest or extradite suspects, but can put government leaders on the spot and limit suspects’ travel.

After receiving a request, Interpol meets by committee and discusses whether or not to share the information with its member states. Interpol has no requirement for making any of the notices public, though some do get published on its website.

It is unlikely Interpol would grant Iran’s request as its guideline for notices forbids it from “undertaking any intervention or activities of a political” nature.

The U.S. killed Soleimani, who oversaw the Revolutionary Guard’s expeditionary Quds Force, and others in the January strike near Baghdad International Airport. It came after months of incidents raising tensions between the two countries and ultimately saw Iran retaliate with a ballistic missile strike targeting American troops in Iraq.

Feb 22: A 20-year-old Chinese woman from Wuhan, the epicentre of the coronavirus outbreak, travelled 400 miles(675 km) north to Anyang where she infected five relatives, without ever showing signs of infection, Chinese scientists reported on Friday, offering new evidence that the virus can be spread asymptomatically.

The case study, published in the Journal of the American Medical Association, offered clues about how the coronavirus is spreading, and suggested why it may be difficult to stop.

"Scientists have been asking if you can have this infection and not be ill? The answer is apparently, yes," said Dr. William Schaffner, an infectious disease expert at Vanderbilt University Medical Center, who was not involved in the study.

China has reported a total of 75,567 cases of the virus known as COVID-19 to the World Health Organization (WHO) including 2,239 deaths, and the virus has already spread to 26 countries and territories outside of mainland China.

Researchers have reported sporadic accounts of individuals without any symptoms spreading the virus. What's different in this study is that it offers a natural lab experiment of sorts, Schaffner said.

"You had this patient from Wuhan where the virus is, travelling to where the virus wasn't. She remained asymptomatic and infected a bunch of family members and you had a group of physicians who immediately seized on the moment and tested everyone."

According to the report by Dr Meiyun Wang of the People's Hospital of Zhengzhou University and colleagues, the woman travelled from Wuhan to Anyang on Jan. 10 and visited several relatives. When they started getting sick, doctors isolated the woman and tested her for coronavirus. Initially, the young woman tested negative for the virus, but a follow-up test was positive.

All five of her relatives developed COVID-19 pneumonia, but as of Feb. 11, the young woman still had not developed any symptoms, her chest CT remained normal and she had no fever, stomach or respiratory symptoms, such as cough or sore throat.

Scientists in the study said if the findings are replicated, "the prevention of COVID-19 infection could prove challenging."

Key questions now, Schaffner said, are how often does this kind of transmission occur and when during the asymptomatic period does a person test positive for the virus.
