Syria-bound Russian military jet crashes with 92 onboard

Washington, May 27: Most viruses and other germs do not spread easily on flights, the US Center for Disease Control and Prevention has said in its COVID-19 guidelines which do not recommend following social distancing between two passengers inside a plane or keeping the middle seat unoccupied.

As a result of coronavirus pandemic, air traffic inside the US has come to a near halt. Air traffic is said to be down to about 90 per cent. For all travellers coming from overseas, the Center for Disease Control and Prevention (CDC) has recommended 14 days quarantine.

"Most viruses and other germs do not spread easily on flights because of how air circulates and is filtered on aeroplanes," the CDC has said in its set of COVID-19 guidelines for air travellers.

However, it noted that the air travellers were not risk-free especially in the time of the coronavirus pandemic and recommended Americans to avoid travel as far as possible.

"Air travel requires spending time in security lines and airport terminals, which can bring you in close contact with other people and frequently touched surfaces," it said.

"Social distancing is difficult on crowded flights, and you may have to sit near others (within six feet), sometimes for hours. This may increase your risk for exposure to the virus that causes COVID-19," the CDC said.

But instead of recommended social distancing inside commercial planes, the CDC has advised a series of preventive and hygienic measures to be taken by the airlines pilot and crew to prevent the spread of coronavirus.

The US Department of Transportation and Federal Aviation Administration in its latest safety alerts for operators on May 11 said that air carriers and crews conducting flight operations having a nexus to the US, including both domestic and foreign air carriers, should follow CDC's occupational health and safety guidance.

The CDC issued its guidelines in first guidelines for the airlines and airline crew on March and again in May.

The CDC, which has issued an exhaustive social guideline measures in various sections, is silent on keeping the middle seat of a plane unoccupied so as to maintain the six feet distance between two passengers.

It calls for the plane crew to report to the CDC a traveller with specific COVID-19 symptoms like fever, persistent cough, difficulty in breathing and appearing unwell.

Asking the airlines and cabin crew to review infection control guidelines for cabin crew, the CDC recommends several measures for cabin crew to protect themselves and others, manage a sick traveller, clean contaminated areas, and take actions after a flight.

Prominent among them include washing hands often with soap and water for at least 20 seconds, particularly after assisting sick travellers or touching potentially contaminated body fluids or surfaces and use of alcohol-based hand sanitizer (containing at least 60 per cent alcohol) if soap and water are not available.

Airlines should consider providing alcohol-based hand sanitizer to cabin and flight crews for their personal use, it said.

The CDC guidelines do not recommend following social distancing inside a plane between two passengers or keeping the middle seat unoccupied. But it asks to minimise contact between passengers and cabin crew and the sick person.

"If possible, separate the sick person from others (by a distance of 2 meters or 6 feet, ideally) and designate one crew member to serve the sick person. Offer a facemask, if available and if the sick person can tolerate it. If a facemask is not available or cannot be tolerated, ask the sick person to cover their mouth and nose with tissues when coughing or sneezing," said the CDC guidelines.

If no symptomatic passengers were identified during or immediately after the flight, the CDC recommends airlines to follow routine operating procedures for cleaning aircraft, managing solid waste, and wearing PPE.

"If symptomatic passengers are identified during or immediately after the flight, routine cleaning procedures should be followed, and enhanced cleaning procedures should also be used," it said.

Clean porous (soft) surfaces (e.g, cloth seats, cloth seat belts) at the seat of the symptomatic passengers and within 6 feet of the symptomatic passengers in all directions, it added.

Jun 9: The World Health Organization says it still believes the spread of the coronavirus from people without symptoms is “rare,” despite warnings from numerous experts worldwide that such transmission is more frequent and likely explains why the pandemic has been so hard to contain.

Maria Van Kerkhove, WHO''s technical lead on COVID-19 said at a press briefing on Monday that many countries are reporting cases of spread from people who are asymptomatic, or those with no clinical symptoms.

But when questioned in more detail about these cases, Van Kerkhove said many of them turn out to have mild disease, or unusual symptoms.

Although health officials in countries including Britain, the U.S. and elsewhere have warned that COVID-19 is spreading from people without symptoms, WHO has maintained that this type of spread is not a driver of the pandemic and is probably accounts for about 6 per cent of spread, at most.

Numerous studies have suggested that the virus is spreading from people without symptoms, but many of those are either anecdotal reports or based on modeling.

Van Kerkhove said that based on data from countries, when people with no symptoms of COVID-19 are tracked over a long period to see if they spread the disease, there are very few cases of spread.

“We are constantly looking at this data and we''re trying to get more information from countries to truly answer this question,” she said. “It still appears to be rare that asymptomatic individuals actually transmit onward.”

Sheikhupura, May 26: Younus, the brother-in-law of Asia Bibi, a Christian woman convicted of blasphemy by a Pakistani court, was killed in Sheikhupura city of Punjab province in Pakistan on Monday.

According to the FIR, Younus had gone to his farms on May 24 and did not return home at night. His body with throat slit was traced in the farm the following morning.

It is believed that, hailing from minority Christian community, Younus was killed in a rivalry.

This is not the first time that somebody associated with Asia Bibi has been murdered in cold blood.

In 2011, Salman Taseer, the influential governor of Punjab was assassinated after he made headlines by appealing for the pardon of Asia Bibi, who had been sentenced to death for allegedly insulting Prophet Muhammad.

A month after Taseer was killed, Religious Minorities Minister Shahbaz Bhatti, a Christian who spoke out against the laws, was shot dead in Islamabad, underlining the threat faced by critics of the law.

Asia Bibi is now living in exile after the Supreme Court of Pakistan acquitted her based on insufficient evidence in October 2018.

Recounting the hellish conditions of eight years spent on death row on blasphemy charges but also the pain of exile, Asia Bibi recently broke her silence to give her first personal insight into an ordeal that caused international outrage.

French journalist Anne-Isabelle Tollet, who has co-written a book about her, was once based in the country where she led a support campaign for her."You already know my story through the media," she said in the book.

"But you are far from understanding my daily life in prison or my new life," she said. "I became a prisoner of fanaticism," she said. In prison, "tears were the only companions in the cell".

She described the horrendous conditions in squalid jails in Pakistan where she was kept chained and jeered at by other detainees.

Pakistan's blasphemy laws carry a potential death sentence for anyone who insults Islam. Critics say they have been used to persecute minority faiths and unfairly target minorities.

Pakistan's Prime Minister Imran Khan defended the country's strict blasphemy laws during his election campaigns. The status quo is still in place.

No government in Pakistan was ready to make changed to the blasphemy law due to fears of a backlash.
