Clouds do prevent radars from detecting accurately: Air Marshal Raghunath Nambiar

United Nations, Jun 6: The coronavirus disease has not "exploded" in India, but the risk of that happening remains as the country moves towards unlocking its nationwide lockdown that was imposed in March to contain the Covid-19, according to a top WHO expert.

WHO Health Emergencies Programme Executive Director Michael Ryan on Friday said the doubling time of the coronavirus cases in India is about three weeks at this stage.

“So the direction of travel of the epidemic is not exponential but it is still growing,” he said, adding that the impact of the pandemic is different in different parts of India and varies between urban and rural settings.

“In South Asia, not just in India but in Bangladesh and...in Pakistan, other countries in South Asia, with large dense populations, the disease has not exploded. But there is always the risk of that happening,” Ryan said in Geneva.

He stressed that as the disease generates and creates a foothold in communities, it can accelerate at any time as has been seen in a number of settings.

Ryan noted that measures taken in India such as the nationwide lockdown have had an impact in slowing transmission but the risk of an increase in cases looms as the country opens up.

“The measures taken in India certainly had an impact in dampening transmission and as India, as in other large countries, open up and as people begin to move again, there's always a risk of the disease bouncing back up,” he said.

He added that there are specific issues in India regarding the large amount of migration, the dense populations in the urban environment and the fact that many workers have no choice but to go to work every day.

India went past Italy to become the sixth worst-hit nation by the COVID-19 pandemic.

India saw a record single-day jump of 9,887 coronavirus cases and 294 deaths on Saturday, pushing the nationwide infection tally to 2,36,657 and the death toll to 6,642, according to the health ministry.

The lockdown in India, was first clamped on March 25 and spanned for 21 days, while the second phase of the curbs began on April 15 and stretched for 19 days till May 3. The third phase of the lockdown was in effect for 14 days and ended on May 17. The fourth phase ended on May 31.

The country had registered 512 coronavirus infection cases till March 24.

The nation-wide lockdown in containment zones will continue till June 30 in India but extensive relaxations in a phased manner from June 8 are listed in the Union home ministry's fresh guidelines on tackling the Covid-19 pandemic issued last week.

WHO Chief Scientist Soumya Swaminathan said the over 200,000 current coronavirus cases in India, a country of over 1.3 billion people, "look big but for a country of this size, it's still modest.”

She stressed that it is important for India to keep track of the growth rate, the doubling time of the virus and to make sure that that number doesn't get worse.

She said that India is a “heterogeneous and huge country” with very densely populated cities and much lower density in some rural areas and varying health systems in different states and these offer challenges to the control of Covid-19.

Swaminathan added that as the lockdown and restrictions are lifted, it must be ensured that all precautions are taken by people.

“We've been making this point repeatedly that really if you want behaviour change at a large level, people need to understand the rationale for asking them to do certain things (such as) wearing masks,” she said.

In many urban areas in India, it's impossible to maintain physical distancing, she said adding that it then becomes very important for people to wear appropriate face coverings when they are out, in office settings, in public transport and educational institutions.

“As some states are thinking about opening, every institution, organisation, industry and sector needs to think about what are the measures that need to be put in place before you can allow a functioning and it may never be back to normal.”

She said that in many professions working from home can be encouraged but in several jobs, people have to go to work and in such cases measures must be put in place that allow people to protect themselves and others.

“I think communication and behaviour change is a very large part of this whole exercise,” she added.

Kabul, May 11: Four back-to-back roadside bombs exploded in a northern district of Afghanistan's capital Kabul on Monday, wounding four civilians including a child, police said. Kabul police spokesman Ferdaws Faramarz said a clearance team was at the site of the attacks.

Militants have carried out several roadside bombings and rocket attacks in Kabul and other parts of the country in recent weeks, but Monday's four consecutive explosions appeared to be the first coordinated effort for some months.

The Taliban has not carried out any large attacks in the city since they signed a landmark withdrawal deal with the US in February, meant to pave the way for peace in the country. No group has claimed the attacks. The explosions come as authorities are trying to impose a lockdown in the capital to curb the spread of coronavirus in the country.

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.
