Venkaiah Naidu takes oath as Vice-President of India

Riyadh, Feb 28: Saudi Arabia on Thursday (Feb 27) suspended visas for visits to Islam's holiest sites for the "umrah" pilgrimage, an unprecedented move triggered by coronavirus fears that raises questions over the annual hajj.

The kingdom, which hosts millions of pilgrims every year in the cities of Mecca and Medina, also suspended visas for tourists from countries with reported infections as fears of a pandemic deepen.

Saudi Arabia, which so far has reported no cases of the virus but has expressed alarm over its spread in neighbouring countries, said the suspensions were temporary. It provided no timeframe for when they will be lifted.

"The kingdom's government has decided to take the following precautions: suspending entry to the kingdom for the purpose of umrah and visit to the Prophet's mosque temporarily," the foreign ministry said in a statement.

"Suspending entry into the kingdom with tourist visas for those coming from countries, in which the spread of the new coronavirus (COVID-19) is a danger."

The move comes as Gulf countries implement a raft of measures, including flight suspensions and school closures, to curb the spread of the disease from people returning from pilgrimages to Iran.

Even as the number of fresh coronavirus cases declines at the epicentre of the disease in China, there has been a sudden increase across the Middle East.

Since its outbreak, the United Arab Emirates has reported 13 coronavirus cases, Kuwait has recorded 43, Bahrain has 33 and Oman is at four cases.

Iran has emerged as a major hotspot in the region, with 19 fatalities from 139 infections - the highest death toll outside China, where COVID-19 originated.

While no cases have been reported in Saudi Arabia, one citizen is reported to be infected in Kuwait along with four Saudi women in Bahrain - all of whom had returned from Iran.

'UNPRECEDENTED' MOVE

The umrah, which refers to the Islamic pilgrimage to Mecca that can be undertaken at any time of year, attracts millions of devout Muslims from all over the globe each year.

There was no clarity over how the move would affect the annual hajj pilgrimage due to start in late July.

Some 2.5 million faithful travelled to Saudi Arabia from across the world to take part in last year's hajj - one of the five pillars of Islam.

The event is a key rite of passage for Muslims and a massive logistical challenge for Saudi authorities, with colossal crowds cramming into relatively small holy sites.

"This move by Saudi Arabia is unprecedented," Ghanem Nuseibeh, founder of London-based risk consultancy Cornerstone Global Associates, told news agency.

"The concern for Saudi authorities would be Ramadan, which starts at the end of April, and hajj afterwards, should the coronavirus become a pandemic."

The holy fasting month of Ramadan is considered a favourable period by Muslim pilgrims to perform the umrah.

Saudi Arabia's custodianship of Mecca and Medina - Islam's two holiest sites - is seen as the kingdom's most powerful source of political legitimacy.

But a series of deadly disasters over the years has prompted criticism of the Sunni kingdom's management of the pilgrimage.

In September 2015, a stampede killed up to 2,300 worshippers - including hundreds of Iranians - in the worst disaster ever to strike the pilgrimage.

The pilgrimage forms a crucial source of revenue for the government, which hopes to welcome 30 million pilgrims annually to the kingdom by 2030.

De facto ruler Crown Prince Mohammed bin Salman's Vision 2030 reform plan seeks to shift the economy of Saudi Arabia - the world's top crude exporter - away from oil dependency towards other sources of revenue, including religious tourism.

The Centre on Sunday extended the COVID-19 lockdown for two more weeks till May 31 with more exemptions as the Centre allowed states more powers for profiling its zones, re-starting of inter-state and intra-state bus travel, plying of autos and taxis and opening of all shops, including in markets but barring those in malls.

Here are the answers to all your questions:

What is 'Lockdown 4.0'?

On March 24, 2020, Prime Minister Narendra Modi announced a 21-day nation-wide lockdown to prevent the spread of the coronavirus outbreak. India follows several countries in its measures to curb the pandemic, which was the first lockdown. Prime Minister then extended the coronavirus lockdown till May 3, which was dubbed as 'Lockdown 2.0'. This lockdown was further prolonged till May 17 which became 'Lockdown 3.0' and now, as the government aims at a staggered re-opening of the country while maintaining the norms such as social distancing, the fourth extension till May 31 is called 'Lockdown 4.0'.

Who issues the guidelines for the lockdown?

The Ministry of Home Affairs (MHA) issues the guidelines for the lockdown.

Are guidelines different during a lockdown compared to normal life?

Well, of course. Guidelines during a lockdown instruct people on all matters from whether you are allowed to leave your house, to whether an MNC is allowed to function and with what percentage of attendance.

Are masks compulsory even now?

Masks are made mandatory in all public places, by the Union Health Ministry. All the states and UTs are to strictly abide by this law. Not wearing masks will attract penalties which are specified by the state.

How would that be determined for an area?

By Lockdown 3.0, all areas of state districts were segregated into containment, red, orange and green zones. In the Lockdown 4.0, states will categorise the areas into red, orange and green zones.

Colourful... but what are red, orange and green zones?

According to the guidelines issued by the Ministry of Health and Family Welfare, states can categorise districts or municipal corporations as red or orange zones.

"States may, however, also choose to categorise a sub-division or ward or any other appropriate administrative unit as red/orange/green zone after detailed analysis at their end, duly taking into consideration the geographical spread of cases, contacts and their zone of influence in terms of disease spread," the ministry said.

With the commencement of the third phase of lockdown, the Union Health Ministry listed 130 districts across the country in the red zone, 284 in the orange zone and 319 in green zones based on the incidence of cases of COVID-19, doubling rate, the extent of testing and surveillance feedback.

Districts were earlier designated as hotspots/red-zones, orange zones and green zones primarily based on the cumulative cases reported and the doubling rate.

A district will be considered under green zone if there have been no confirmed cases of COVID-19 so far or there is no reported case since last 21 days in the district, according to the letter.

Now, what is a buffer zone?

A buffer zone is an area of spread in a 5-kilometre radius (7 Kms in rural areas) of a containment zone.

How do I find out the zone I am in?

You either look at your state or city's municipal corporation pages to avail the zone details. You can also look at your district magistrate's Twitter handle or Facebook account to find out the list of the zone under which your area falls.

Can I leave my home now?

That depends. If you are in a containment zone or a red zone, you may not be allowed to leave your residence. Otherwise, in the other zones, the state governments and the district magistrates will decide upon the level of movement within and outside the zones.

Can I shift from a red zone to an orange or green zone?

You cannot. The residents of a red or containment zone cannot move out of their zones, nobody may enter the zones as well.

What about my office?

The private offices can operate in non-containment zones. The guidelines for offices to work will be listed by the state governments and the DMs (district magistrates).

Will I be allowed to use my bike/car or any other personal vehicle?

There is a likely chance of you being allowed to take out your bike or car or other vehicles (not helicopters or aeroplanes), if you are not in a containment zone. You need to check the rules listed by your state government or DM. The number of people who can ride at one time will also be decided by the state.

Can my driver, house help or neighbour drive me to my office/destination? Will I be allowed to take them to my workplace?

Yes, provided they are not from a red zone which may be risky for the passenger. This facility is prohibited in a containment zone. Also, check with your workplace regarding the norms to follow within the office. For the details on travelling with others in the car, look into the info provided by your state government, DM and Resident Welfare Association (RWA).

Will be able to fill petrol or diesel for my vehicle?

Definitely, yes. All petrol pumps, LPG and oil agencies will continue to be open.

What if I need to take a cab, auto or book one via Ola/Uber?

The same rules apply to them as well. Unless you are in a containment zone, the restrictions for using cabs and autos will be eased.

What if I need to use public transport like buses?

Some states have allowed buses to run, such as in Tamil Nadu in certain areas. You will have to check with the state government or DM's regulations enlisted for knowing the routes and norms to follow inside a bus.

Can I use my city's Metro line?

Unfortunately, metro lines are not allowed to open and will remain closed until further notification from the Centre.

Can I walk around in my area?

Walking will be permitted under the guidelines issued by the state and DM. Walking in groups will be prohibited and social distancing norms are to be followed in public at all times. Movement is allowed between 7 am to 7 pm in any zone - containment, red, orange or green.

Can I take my grandparents/kids out for a walk?

People older than 65 years of age, or younger than 10, persons with co-morbidities, pregnant women are not allowed to venture out of their residences, as they are highly susceptible to the infection.

Can I go out with my friends?

A group of less than 5 people are allowed to walk together. If you are planning to use vehicles such as bikes, every induvial must have their own as more than one person on atwo-wheeler is not allowed in certain areas. Curfew timings are from 7 am to 7 pm as movent is prohibited beyond these timings. Check the regulations issued by your local DM or state government to know further details.

What if I need to see my friends, relatives or others?

The Resident Welfare Association (RWA) will make a decision about allowing visitors inside a zone, barring containment zones. Nobody is allowed within the containment zone or permitted to leave.

Can we now go to restaurants?

Restaurants are still closed irrespective of the zone. Take-away or delivery services will be available, nevertheless.

Can we go to malls?

Malls and restaurants and shops in the malls will remain closed irrespective of the zone, as these are crowd-pulling zones.

Does that mean multiplexes, theatres and drama/concert halls are closed as well?

Cinema halls, theatres, multiplexes and drama/concert halls will remain closed regardless of which zone they are in, till further instructions are sent by the Centre.

Can I go to the beach or a monument/heritage site?

Since such public places will attract a huge crowd that will be tough to control, beaches, monuments, heritage sites and such public places will be closed.

Can I go to coffee shops?

As coffee shops will fall under the category of restaurants, they will also be closed. Take-away and delivery services can be availed from the shops.

What about essentials?

Grocery shops, milk vendors, newspaper circulation are allowed to stay open. Proper sanitisation must be done from time-to-time to ensure customer and vendors’ safety.

I need to repair my phone. Will stand-alone non-essential services be open?

Such non-essential services are allowed to open in non-containment zones. Refer the state governments and DMs rules for knowing the type of shops and state and districts they are permitted in.

What about in-house repairs or services? Can I call a mechanic to my house?

Yes, provided your RWA has permitted to allow mechanics, workmen and labourers inside in non-containment zones.

New Delhi, May 23: The nationwide lockdown will no longer help India in its fight against COVID-19, and in its place community-driven containment, isolation and quarantine strategies have to be brought into play, leading virologist Shahid Jameel said.

The recipient of Shanti Swarup Bhatnagar Prize for Science and Technology also stressed that testing should be carried out vigorously to identify coronavirus hotspots and isolate those areas.

"Our current testing rate at 1,744 tests per million population is one of the lowest in the world. We should deploy both antibody tests and confirmatory PCR tests. This will tell us about pockets of ongoing infection and past (recovered) infection. This will provide data to open up gradually and let economic activity resume," Jameel told PTI in an interview.

He stressed that testing has to be dynamic to continuously monitor red, orange and green zones and change these based on that data.

About community transmission of COVID-19 in India, Jameel said the country reached that stage long ago.

"We reached community transmission a long time ago. It's just that the health authorities are not admitting it. Even ICMR's own study of SARI (severe acute respiratory illness) showed that about 40 per cent of those who tested positive for SARS-CoV-2 did not have any history of overseas travel or contact to a known case. If this is not community transmission, then what is?" he posed.

Lockdown bought India time in its fight against coronavirus, but continuing it is unlikely to yield any further dividend, Jameel said.

"Instead, community-driven local lockdowns, isolations and quarantines have to come into play. Building trust is most important so that people follow rules. A public health problem cannot be dealt with as a law-and-order problem."

The nationwide lockdown, initially imposed from March 25 to April 14, has been extended thrice and will continue at least till May 31. The virus has claimed 3,720 lives and infected over 1.25 lakh people in the country so far.

Jameel has expertise in the fields of molecular biology, infectious diseases, and biotechnology. He is the CEO of Wellcome Trust/Department of Biotechnology's India Alliance and is best known for extensive research in Hepatitis E virus and HIV.

He said COVID-19 will eventually be controlled through herd immunity, which is acquired in two ways – when a sufficient fraction of the population gets infected and recovers, and with vaccination.

"It is estimated that for SARS-CoV-2 at least 60 per cent of the population would have to be infected and recovered, or vaccinated. This will happen over the course of the next few years," Jameel said.

Herd immunity is reached when the majority of a population becomes immune to an infectious disease, either because they have become infected and recovered, or through vaccination. When that happens, the disease is less likely to spread to people who aren't immune, because there just aren't enough infectious carriers.

"India has 1.38 billion people, a population density of about 400/sq km and a healthcare system ranked at 143 in the world. If we allow 60 per cent people to get infected quickly in the hopes of herd immunity, that would mean 830 million infections," Jameel said.

"If 15 per cent need hospitalization that means about 125 million isolation beds (we have 0.3 million). If five per cent need oxygen and ventilatory support, this amounts to about 42 million oxygen support and ICU beds; we have 0.1 million oxygen support beds and 34,000 ICU beds. This would overwhelm the healthcare system causing mayhem," he said.

Jameel said if the population level mortality is 0.5 per cent that would mean 40 lakh deaths. "Are we prepared to pay this price for herd immunity in the short term? Clearly not," he said.

He said it is unlikely that a vaccine would be available by the end of the year.

"Even then, we don't know yet how long it would give protection – weeks, months, one year, a few years? I don't think we will return to pre-coronavirus days for at least the next 3-5 years. This is also a chance to evaluate if we want to return to those unsustainable, environment-damaging ways. COVID-19 is a timely warning to reform our way of living," he said.

Jameel said it is hard to predict but plausible that COVID-19 would return in second or third wave.

"Later waves come when we don't understand the disease and become lax. A comparison to Spanish Flu is not entirely valid because in 1918 no one knew what caused it. No one had seen a virus till the mid-1930s as the electron microscope needed to view those was invented in 1931," he said.

"Today we know a lot more about the pathogen, its genetic makeup, how it transmits and how to prevent it. We need to be sensible and follow expert advice," he said.

If there is any scientific evidence linking deforestation, rapid urbanisation, climate change with pandemics like COVID-19, he said zoonotic viruses -- those that jump from animals to humans -- happen so when wild animal–human contacts increase.

"Deforestation destroys animal habitats bringing them closer to humans. When you cut forests, bats come to roost on trees closer to human habitations. Their viruses in secretions/stool get transmitted to domestic animals and on to humans. This happened clearly with Nipah virus outbreak in Malaysia in 1997-98 from fruit bats to pigs to humans," he said.

"COVID-19 possibly arose in wet animal markets due to dietary habits that bring all kinds of live and dead wild animals in close contact with humans," Jameel added.
