The world is still at the beginning of the coronavirus pandemic and it will take some time to work out how to deal with it, an expert has told British MPs.
David Nabarro, who is one of the World Health Organisation's special envoys on COVID-19, told the Foreign Affairs Committee the present situation is horrible and grotesque.
He said the outbreak is worse than any science fiction movie and appears to be getting nastier as cases re-emerge in Europe.
"None of us find the present situation, anything other than horrible grotesque, really embarrassing," Nabarro told MPs on Tuesday.
"It's a terrible situation, a health issue has got so out of control it's knocking the world into, not just a recession, but a huge economic contraction which would probably double the number of poor people, double the number of malnourished, lead to hundreds of millions of small businesses going bankrupt."
He added there was also a risk of the pandemic ruining educational opportunities for a lot of children around the world.
"It's awful. And we really, really are, all of us, deeply saddened and troubled by it," he said.
"But that applies to most people in our world who are all having to make sense of something that they couldn't imagine. It's much worse than any of the science fiction about pandemics."
Nabarro said things were likely to get worse before they get better.
"This is really serious - we're not even in the middle of it yet. We're still at the beginning of it," he said.
"And we're beginning to see what damage it's going to cause the world. And it's getting nastier as we go into this particular phase in Europe of watching the thing come back again."
His comments came in response to a question from Labour MP Chris Bryant, who asked what he should tell his constituents who believe COVID-19 is just a big conspiracy.
Nabarro said that he understood why people thought such things and that everyone would love to find a convenient explanation for the virus.
"I think we've got to entertain the fact that everybody everywhere is looking for an explanation, and we need to level with them and say 'we quite understand it'," he added.
"Based on my understanding this virus was visited on us at the very end of last year, and we've been learning to live with it for this year, and we will make sense of it, and we will be able to work out how to do it but it's going to take us quite a bit longer."
Globally, more than 29.39 million people have been reported to be infected by the coronavirus and 928,463 have died.
