Check in with grandparents during coronavirus lockdown, WHO says

People should check in with their grandparents every day during the coronavirus lockdown to stop them becoming lonely, World Health Organisation boss says

• Hans Kluge, WHO director for Europe, said it’s important to talk every day
• He urged people to support the elderly, but cautioned not to meet in person
• Experts also encouraged elders to keep active to beat the blues
• Most can expect to be ‘shielded’ for at least another eight weeks from now 

People should check in with their grandparents every day during the coronavirus lockdown, World Health Organisation bosses have said.

Hans Kluge, WHO regional director for Europe, said it is ‘everyone’s business’ to support the elderly – particularly those who live alone.

Everyone should take daily actions to help their elderly neighbours, parents and grandparents, he said.

Issuing a ‘message to younger people’, he said: ‘Keep your grandparents safe – but it is vital you don’t visit them in person.

‘Talk to them, talk to them every single day so they don’t feel alone.

‘It is crucial to ensure we stay connected.’

Dr Kluge, speaking in Copenhagen during a WHO briefing on helping the elderly survive the coronavirus crisis, said people should have a daily telephone call with older relatives or use video messaging to keep in touch.

‘Physical distancing is not social isolation,’ he said.

‘Remember, leave no one behind.’

Dr Kluge said it is particularly important that relatives make sure elderly people understand the measures that are in place to protect them.

They should also check they are not ill and are keeping active.

WHAT IS SOCIAL DISTANCING? 

Social distancing measures are used to slow the spread of disease by keeping an appropriate distance between people.

This is two metres in the UK and US, but is 1.5 metres in Australia.

This is because coronavirus can be transmitted by coughing, sneezing, or being in the same space as someone who has the coronavirus for a long period of time.  

The aim of social distancing is also to limit physical contact with each other as much as possible, with the encouragement of working from home, avoiding crowded spaces and public transport as much as possible. 

Social distancing is a behavioral method that buys time for scientists to develop a vaccine. 

However, World Health Organization Director-General Tedros Adhanom Ghebreyesus has said ‘on their own, these measures will not extinguish epidemics’. He has urged for testing to be done on large scale in order to contain cases.

Social distancing measures are: 

• Avoid contact with someone who is displaying symptoms of coronavirus (COVID-19) – these symptoms include high temperature and/or new and continuous cough.
• Avoid non-essential use of public transport – when possible, alter your travel times to avoid rush hour.
• Work from home, where possible – your employer should support you to do this.
• Avoid large gatherings and small gatherings in public spaces – pubs, restaurants, leisure centres and similar venues are currently closed as infections spread easily in closed spaces where people gather together.
• Avoid gatherings with friends and family – keep in touch using remote technology such as phone, internet, and social media.
• Use telephone or online services to contact your GP or other essential services

Alana Officer, health advisor at the WHO, said all people – especially the elderly – should be aiming to do 30 minutes of exercise a day to make sure the lock-down does not result in long-term health impacts, particularly on balance and strength.

Even if they cannot get outside they must try to do exercises in the house – and it is up to family members to encourage them, she said.

Catherine Smallwood, WHO health emergency officer, said encouraging elderly people to do things they enjoy each day can help keep loneliness at bay.

This could involve doing hobbies, speaking to loved ones, or going for a walk, she said.

People must stay indoors if they are suffering coronavirus symptoms or have been told they must be ‘shielded’ because they have other serious health conditions.

But if they are not in these groups a daily walk is to be recommended, Dr Smallwood said.

‘Going for gentle walks is certainly a good way to keep healthy to get some exercise and to preserve our mental wellbeing, Dr Smallwood said.

‘Remaining cooped up at home is challenging for all of us and this especially for those who are older.’

Dr Kluge said young people must also take the social-distancing more seriously to protect the elderly.

Older people are far more vulnerable to coronavirus, he said.

Some 95 per cent of European deaths so far have been among the over-60s and 50 per cent among over-80s.

But young people are not immune and they risk spreading the virus to the old if they ignore distancing measures.

‘Young people are not invincible,’ Dr Kluge said, warning that there have been deaths among people in their teens or 20s – such as the tragic case of a healthy 13-year-old boy who died in London earlier this week.

But he said getting coronavirus, even in old age, is not necessarily a death sentence.

Even for people in their 70s, nine in ten patients will recover.

‘On a positive note there are reports of people over the age of 100 who were admitted to hospital for Covid-19 who have made a full recovery,’ Dr Kluge said.

But this depends on people staying fit and healthy in old age so that if coronavirus does strike, the body is better able to ward it off.

‘People who age healthily are less at risk,’ Dr Kluge said.

WHAT DO WE KNOW ABOUT THE CORONAVIRUS?

What is the coronavirus? 

A coronavirus is a type of virus which can cause illness in animals and people. Viruses break into cells inside their host and use them to reproduce itself and disrupt the body’s normal functions. Coronaviruses are named after the Latin word ‘corona’, which means crown, because they are encased by a spiked shell which resembles a royal crown.

The coronavirus from Wuhan is one which has never been seen before this outbreak. It has been named SARS-CoV-2 by the International Committee on Taxonomy of Viruses. The name stands for Severe Acute Respiratory Syndrome coronavirus 2.

Experts say the bug, which has killed around one in 50 patients since the outbreak began in December, is a ‘sister’ of the SARS illness which hit China in 2002, so has been named after it.

The disease that the virus causes has been named COVID-19, which stands for coronavirus disease 2019.

Dr Helena Maier, from the Pirbright Institute, said: ‘Coronaviruses are a family of viruses that infect a wide range of different species including humans, cattle, pigs, chickens, dogs, cats and wild animals. 

‘Until this new coronavirus was identified, there were only six different coronaviruses known to infect humans. Four of these cause a mild common cold-type illness, but since 2002 there has been the emergence of two new coronaviruses that can infect humans and result in more severe disease (Severe acute respiratory syndrome (SARS) and Middle East respiratory syndrome (MERS) coronaviruses). 

‘Coronaviruses are known to be able to occasionally jump from one species to another and that is what happened in the case of SARS, MERS and the new coronavirus. The animal origin of the new coronavirus is not yet known.’ 

The first human cases were publicly reported from the Chinese city of Wuhan, where approximately 11million people live, after medics first started publicly reporting infections on December 31.

By January 8, 59 suspected cases had been reported and seven people were in critical condition. Tests were developed for the new virus and recorded cases started to surge.

The first person died that week and, by January 16, two were dead and 41 cases were confirmed. The next day, scientists predicted that 1,700 people had become infected, possibly up to 7,000. 

Where does the virus come from?

According to scientists, the virus almost certainly came from bats. Coronaviruses in general tend to originate in animals – the similar SARS and MERS viruses are believed to have originated in civet cats and camels, respectively.

The first cases of COVID-19 came from people visiting or working in a live animal market in Wuhan, which has since been closed down for investigation.

Although the market is officially a seafood market, other dead and living animals were being sold there, including wolf cubs, salamanders, snakes, peacocks, porcupines and camel meat. 

A study by the Wuhan Institute of Virology, published in February 2020 in the scientific journal Nature, found that the genetic make-up virus samples found in patients in China is 96 per cent identical to a coronavirus they found in bats.

However, there were not many bats at the market so scientists say it was likely there was an animal which acted as a middle-man, contracting it from a bat before then transmitting it to a human. It has not yet been confirmed what type of animal this was.

Dr Michael Skinner, a virologist at Imperial College London, was not involved with the research but said: ‘The discovery definitely places the origin of nCoV in bats in China.

‘We still do not know whether another species served as an intermediate host to amplify the virus, and possibly even to bring it to the market, nor what species that host might have been.’  

So far the fatalities are quite low. Why are health experts so worried about it? 

Experts say the international community is concerned about the virus because so little is known about it and it appears to be spreading quickly.

It is similar to SARS, which infected 8,000 people and killed nearly 800 in an outbreak in Asia in 2003, in that it is a type of coronavirus which infects humans’ lungs. It is less deadly than SARS, however, which killed around one in 10 people, compared to approximately one in 50 for COVID-19.

Another reason for concern is that nobody has any immunity to the virus because they’ve never encountered it before. This means it may be able to cause more damage than viruses we come across often, like the flu or common cold.

Speaking at a briefing in January, Oxford University professor, Dr Peter Horby, said: ‘Novel viruses can spread much faster through the population than viruses which circulate all the time because we have no immunity to them.

‘Most seasonal flu viruses have a case fatality rate of less than one in 1,000 people. Here we’re talking about a virus where we don’t understand fully the severity spectrum but it’s possible the case fatality rate could be as high as two per cent.’

If the death rate is truly two per cent, that means two out of every 100 patients who get it will die. 

‘My feeling is it’s lower,’ Dr Horby added. ‘We’re probably missing this iceberg of milder cases. But that’s the current circumstance we’re in.

‘Two per cent case fatality rate is comparable to the Spanish Flu pandemic in 1918 so it is a significant concern globally.’

How does the virus spread?

The illness can spread between people just through coughs and sneezes, making it an extremely contagious infection. And it may also spread even before someone has symptoms.

It is believed to travel in the saliva and even through water in the eyes, therefore close contact, kissing, and sharing cutlery or utensils are all risky. It can also live on surfaces, such as plastic and steel, for up to 72 hours, meaning people can catch it by touching contaminated surfaces.

Originally, people were thought to be catching it from a live animal market in Wuhan city. But cases soon began to emerge in people who had never been there, which forced medics to realise it was spreading from person to person. 

What does the virus do to you? What are the symptoms?

Once someone has caught the COVID-19 virus it may take between two and 14 days, or even longer, for them to show any symptoms – but they may still be contagious during this time.

If and when they do become ill, typical signs include a runny nose, a cough, sore throat and a fever (high temperature). The vast majority of patients will recover from these without any issues, and many will need no medical help at all.

In a small group of patients, who seem mainly to be the elderly or those with long-term illnesses, it can lead to pneumonia. Pneumonia is an infection in which the insides of the lungs swell up and fill with fluid. It makes it increasingly difficult to breathe and, if left untreated, can be fatal and suffocate people.

Figures are showing that young children do not seem to be particularly badly affected by the virus, which they say is peculiar considering their susceptibility to flu, but it is not clear why. 

What have genetic tests revealed about the virus? 

Scientists in China have recorded the genetic sequences of around 19 strains of the virus and released them to experts working around the world. 

This allows others to study them, develop tests and potentially look into treating the illness they cause.   

Examinations have revealed the coronavirus did not change much – changing is known as mutating – much during the early stages of its spread.

However, the director-general of China’s Center for Disease Control and Prevention, Gao Fu, said the virus was mutating and adapting as it spread through people.

This means efforts to study the virus and to potentially control it may be made extra difficult because the virus might look different every time scientists analyse it.   

More study may be able to reveal whether the virus first infected a small number of people then change and spread from them, or whether there were various versions of the virus coming from animals which have developed separately.

How dangerous is the virus?  

The virus has a death rate of around two per cent. This is a similar death rate to the Spanish Flu outbreak which, in 1918, went on to kill around 50million people.

Experts have been conflicted since the beginning of the outbreak about whether the true number of people who are infected is significantly higher than the official numbers of recorded cases. Some people are expected to have such mild symptoms that they never even realise they are ill unless they’re tested, so only the more serious cases get discovered, making the death toll seem higher than it really is.

However, an investigation into government surveillance in China said it had found no reason to believe this was true.

Dr Bruce Aylward, a World Health Organization official who went on a mission to China, said there was no evidence that figures were only showing the tip of the iceberg, and said recording appeared to be accurate, Stat News reported.

Can the virus be cured? 

The COVID-19 virus cannot be cured and it is proving difficult to contain.

Antibiotics do not work against viruses, so they are out of the question. Antiviral drugs can work, but the process of understanding a virus then developing and producing drugs to treat it would take years and huge amounts of money.

No vaccine exists for the coronavirus yet and it’s not likely one will be developed in time to be of any use in this outbreak, for similar reasons to the above.

The National Institutes of Health in the US, and Baylor University in Waco, Texas, say they are working on a vaccine based on what they know about coronaviruses in general, using information from the SARS outbreak. But this may take a year or more to develop, according to Pharmaceutical Technology.

Currently, governments and health authorities are working to contain the virus and to care for patients who are sick and stop them infecting other people.

People who catch the illness are being quarantined in hospitals, where their symptoms can be treated and they will be away from the uninfected public.

And airports around the world are putting in place screening measures such as having doctors on-site, taking people’s temperatures to check for fevers and using thermal screening to spot those who might be ill (infection causes a raised temperature).

However, it can take weeks for symptoms to appear, so there is only a small likelihood that patients will be spotted up in an airport.

Is this outbreak an epidemic or a pandemic?   

The outbreak was declared a pandemic on March 11. A pandemic is defined by the World Health Organization as the ‘worldwide spread of a new disease’. 

Previously, the UN agency said most cases outside of Hubei had been ‘spillover’ from the epicentre, so the disease wasn’t actually spreading actively around the world.
