WHO says coronavirus is not necessarily 'the big one' and a more deadly pandemic could sweep the globe

 

Dr Mike Ryan said the pandemic was a 'wake-up call' that the planet is fragile.

He said it had shown science, logistics, training and government needed to improve to manage future global health crises  better.

Experts from the WHO spoke at the year's final press briefing on Tuesday.

Director General Tedros Adhanom Ghebreyesus praised progress made so far but noted new variants of Covid-19 and pandemic fatigue as challenges ahead.

As the world struggles with the problems created by the coronavirus pandemic outbreak, the World Health Organization (WHO) has issued a grim warning that the worse may yet to come.

The news report from Mail, it states that the World Health Organization has warned that the coronavirus pandemic is 'not necessarily the big one' and that a more deadly virus could yet sweep the globe.

Dr Mike Ryan, head of the WHO emergencies programme, said on Tuesday that the pandemic was a 'wake-up call'.

'This pandemic has been very severe… it has affected every corner of this planet. But this is not necessarily the big one,' he told a media briefing.

The coronavirus has so far killed 1,799, 337 people world wide and the most recent SAGE estimates put its infection fatality rate at 0.5%, meaning it kills one of every 200 people infected.  

Spanish Flu was the last major global pandemic and killed in excess of 50million people between 1918 and 1919. It was much more deadly to younger people and there was a high mortality rate among those aged 20-40 years old. 

It's Infection fatality rate was 2.5%, and it is feared that a similarly deadly global pandemic today would shut down global civilisation, potentially disrupting food supplies as workers in global supply chains stay home over fears for them and their families. 

Food shortages could spark global unrest much bigger than the riots that were provoked by outrage over the death of George Floyd in the middle of the pandemic this year. 

And the stability of governments across the globe could be threatened by such widespread unrest. 

The Black Death is believed to be the world's deadliest pandemic and killed between 75million and 200million people across Africa, Europe and Asia between 1347 and 1351. 

Dr Ryan added: 'This [coronavirus] is a wake-up call. We are learning, now, how to do things better: science, logistics, training and governance, how to communicate better. But the planet is fragile.

'We live in an increasingly complex global society. These threats will continue. If there is one thing we need to take from this pandemic, with all of the tragedy and loss, is we need to get our act together. We need to honour those we've lost by getting better at what we do every day.'

Ryan also said that the virus was likely to remain part of our lives despite the introduction of vaccines that have started to be rolled out in Europe and the United States. 

'The likely scenario is the virus will become another endemic virus that will remain something of a threat, but a very low-level threat in the context of an effective global vaccination programme.'

'It remains to be seen how well the vaccines are taken up, how close we get to a coverage level that might allow us the opportunity to go for elimination.

'The existence of a vaccine, even at high efficacy, is no guarantee of eliminating or eradicating an infectious disease. That is a very high bar for us to be able to get over,' he said. 

Ryan said that was why the vaccine distribution is designed to save lives by protecting the most vulnerable, The Guardian reported.

'And then we will deal with the moonshot of potentially being able to eliminate or eradicate this virus.'

Professor David Heymann, chair of the WHO's strategic and technical advisory group for infectious hazards, told the briefing earlier that it was the 'destiny' of the virus to become endemic.  

'The world has hopes for herd immunity, that somehow transmission would be decreased if enough persons were immune' Heymann said at a media briefing, before explaining that the concept of herd immunity was misunderstood. 

'It appears the destiny of SARS-CoV-2 [Covid-19] is to become endemic, as have four other human coronaviruses, and that it will continue to mutate as it reproduces in human cells, especially in areas of more intense admission.

'Fortunately, we have tools to save lives, and these in combination with good public health will permit us to learn to live with Covid-19.'  

Being vaccinated against the virus did not mean an end to social distancing and other public health measures, chief scientist Dr Soumya Swaminathan told the briefing on Tuesday.

'I don't believe we have the evidence on any of the vaccines to be confident that it's going to prevent people from actually getting the infection and therefore being able to pass it on.

'So I think we need to assume that people who have been vaccinated also need to take the same precautions,' Swaminathan said, adding that the vaccine is intended to prevent symptomatic disease as well as severe cases of infection and deaths.  

At the briefing, which was the global health body's last of the year, director general Tedros Adhanom Ghebreyesus said it was a time to reflect on both the toll of the pandemic and progress made. 

He pointed to new variants of Covid-19 and pandemic fatigue as likely challenges to expect in the year ahead. 

'New ground has been broken, not least with the extraordinary cooperation between the private and public sector in this pandemic. And in recent weeks, safe and effective vaccine rollout has started in a number of countries, which is an incredible scientific achievement,' he said.

'This is fantastic, but WHO will not rest until those in need everywhere have access to the new vaccines and are protected.'

Israel is leading the global vaccination race with more than seven per cent of its population already given the jab in the space of nine days. 

Some 644,000 people have received a dose of the Pfizer/BioNTech jab in the country of 8.7million, the highest per-capita rate in the world. 

The rapid rollout in a country that prides itself on self-reliance comes after Israel's health minister ordered a 24/7 vaccination drive, hundreds of military medics were drafted in to help with the effort and the country ordered shots from all three of Pfizer, Moderna and AstraZeneca in advance. 

Israel is expected to launch a so-called 'green passport' scheme in January which means people immunised against Covid-19 will avoid having to quarantine if they travel from abroad or come into contact with a virus patient.  

Bahrain is second in the global vaccine table, while Britain is third after handing out 800,000 doses in barely two weeks by Christmas Eve - with the UK set to ramp up its vaccine drive after today's approval of the Oxford/AstraZeneca jab. 

The US has given out the most vaccines outright after injecting more than 2.1million people, but president-elect Joe Biden has criticized delays in the rollout. 

Europe started its own programme at the weekend after an EU regulator finally approved the Pfizer jab, with Portugal and Denmark making the fastest progress on the continent so far.
