Hello. This is 6 Minute English from BBC Learning English. Im Neil.
Georgina
And Im Georgina.
Neil
Covid-19 has changed everyday life for people in countries around the world. But coronavirus wasnt the first pandemic to cause mass sickness and disrupt daily life.
Georgina
Between 2002 and 2004 an outbreak of the disease known as SARS or 'severe acute respiratory syndrome' caused hundreds of deaths in southern China before spreading to other parts of the world.
Neil
The virus that caused SARS survived by mutating changing as it reproduced itself in the bodies of infected people and this caused the virus to create strains slight variations of the original.
Georgina
Covid-19, the disease caused by the strain of the original SARS virus we are experiencing now, has been called SARS 2.
Neil
In this programme, well be looking at the origins of Covid-19 and hearing new evidence about the scale of the threat we face from the disease. And of course well be learning some new vocabulary as well. But first its time for our quiz question. We know that white blood cells make up part of the immune system our body needs to fight infectious diseases like Covid-19. But how many white blood cells per microlitre does the average adult human need? Is it:
a) 7,000,
b) 17,000, or
c) 70,000?
Georgina
Hmmm, in that case Id say more is better, so c) 70,000.
Neil
OK, well find out the answer at the end of the programme. Now, Georgina, you mentioned that the disease spreading across the world today wasnt the first Covid-19-type disease.
Georgina
Thats right. In fact a recent research project in China has identified over 700 different types of coronavirus carried by bats. Some of these virus strains are thought to have already crossed over to humans.
Neil
Dr Peter Daszak of New Yorks Eco-Health Alliance thinks that new strains of the virus have the potential to cause future pandemics. He spent years in the Chinese countryside looking for the coronaviruses that could jump from bats to humans.
Georgina
Here he is talking to the BBC World Service programme, Science in Action
Dr Peter Daszak
It would have been great to have found the precursor to SARS 2, but what would have been even better was to have found it before SARS 2 emerged and raise the red flag on it and stop the outbreak. But we didnt do that. What we were looking for were at the time our hypothesis was that SARS 1, the original SARS virus which we all thought had disappeared , was still out there in bats and that was what we were looking for. So we found a lot of SARS 1-related viruses.
Neil
Covid-19 may have been contained if scientists had known more about the diseases precursor that's a situation which existed before something and led to the development of that thing. Here, the precursor of Covid-19 was the original SARS 1.
Georgina
Any new cases of the virus would have been a red flag for another outbreak - a symbol of danger and that some action needs to be taken.
Neil
Dr Daszak believed that some form of SARS remained in bats and based his investigations on this hypothesis an idea which is suggested as a possible explanation of something but which has not yet been proved correct.
Georgina
Another scientist working to prevent new epidemics is the pathologist Professor Mary Fowkes.
Neil
The original SARS was treated as a respiratory disease which attacks the lungs.
Georgina
But when working with infected patients, Professor Fowkes noticed that Covid-19 was damaging the brain, blood and other organs as well.
Prof Mary Fowkes
Clinicians have recognised that a lot of patients that have Covid-19 are exhibiting confusion, are not necessarily aware of their environment appropriately, some are having seizures,so there are some central nervous system abnormalities. And as you know, a lot of patients are exhibiting loss of sense of smell and that is a direct connection to the brain as well.
Neil
In some infected patients coronavirus attacks the central nervous system - the bodys main system of nerve control consisting of the brain and spinal cord.
Georgina
When severe, this can cause seizures - sudden, violent attack of an illness, often affecting the heart or brain.
Neil
It seems that Covid-19-type diseases are not going to disappear any time soon.
Georgina
Reminding us of the importance of the scientific research weve heard about today.
Neil
And the importance of boosting your immunity which reminds me of todays quiz question.
Georgina
You asked me how many white blood cells per microlitre the human body has. I said c) 70,000.
Neil
Well, if thats true youve definitely boosted your immunity, Georgina, because the correct answer is c) 7,000.
Georgina
Today weve been discussing the strains or slight variations, of the virus which causes Covid-19.
Neil
Covid-19 has a previous disease called SARS as its precursor a situation which existed before something and caused the development of that thing.
Georgina
Researchers used the idea that the virus have passed to humans from bats as their hypothesis possible explanation for something which has not yet been proved true.
Neil
By identifying new virus strains, doctors hope unexplained cases can act as a red flag a warning sign of danger, to prevent further outbreaks.
Georgina
Knowing about new strains is increasingly important as we find out more about how coronavirus attacks the bodys central nervous system the brain and spinal cord, which in some patients can cause seizures - sudden, violent attacks of an illness, especially affecting the heart or brain.
Neil
So try to stay safe, wash your hands and remember to join us again soon. Bye for now!
Georgina
Bye!
