dot com megacity. get this click. coronavirus has made us reexamined our leadership with animals the virus originated in a species that was not our own 'd and it follows many others swine flu bird flu a bowler and sars are all what are known as a zone not of diseases that means they jump from animals to humans. scientists hope to catch any potential new ones before they make that leap so what can we do took tremendous other worldwide outbreak spreading from the animal kingdom to us. this is your cover 19 special here on the w. i'm chris they were. warm welcome to more than 11000000 people worldwide have
officially contract of the corona virus so far almost 550000 deaths are linked to covered 19 and while we are still battling this pandemic and prepare for future ones scientists believe it's wise to trace back the steps the virus has been taking . scientists believe the corona virus outbreak in humans may well have begun in a market in the chinese city of. researches say leaps between species happened when humans and animals are in close proximity one hypothesis is that the corona virus jumped from bats to pangolin to people into and causing a global health emergency such leaps can happen in so-called wet markets that's where viruses can easily change their host crossing from one species to another china is home to several wet markets and the international community has been calling for that closure. i think you know should shut down those things right away
we can clearly see. the great risk to the work with the rest of the world. it's currently thought there are over 200 diseases that are spread from animals to humans known as do you know cities about 40 have the potential to cause a pandemic sars ebola aids all are examples of viruses that jump from animals to human beings 3 out of 5 new infectious diseases that emerge originate from another species one estimate puts deaths from diseases caused by as you know sees at 2700000 a year and that was in 2012. china is home to a major wildlife market industry and many chinese rely on it for their livelihoods
the question is whether the will is there for people to change some practices the put everyone's lives at risk. now in china researchers have discovered a new version of the swine flu it belongs to the h one n one virus type which in 2009 kicked of a pandemic that killed more than 800000 people scientists warn that the recently discovered version also has all the current characteristics to pose a threat to humans. this farm in guangxi province in southern china is clean and well run but it doesn't reflect the reality in many other parts of the country where things look more like this. poor hygiene and cramped conditions increase the risk of infection of all kinds including swine flu now against the backdrop of
a global health emergency scientists are warning of the danger of a group of flying flu viruses that have adapted to infect humans the chinese government has criticized the study in question. so the experts have concluded that the sample size of the report is small and not representative relevant departments and experts will continue to strengthen monitoring sent early warnings and handle things in a timely manner would you. after the devastation caused by covert 19 it's in china's interest to take the threat seriously after all the country does not want to become the epicenter of another pandemic it's something that still is in the stage of examination it's not so-called an immediate threat we're seeing infections but it's something we need to keep our eye on just the way we did 2009 with the emergence of the swine flu so far there's been no evidence of person to
person transmission of the new strain of swine flu virus but the last few months have shown just how fast that could change. in a short while ago i spoke to. the manages the global influenza program at the world health organization and i asked her how worried she was about this so-called g 4 strain of the swine flu. so the cheapest rent oaks lie in fresno iris is not new iris cece virus come surprise a surveillance program from tucson that you live and you saw the 18. they were human infections e.c.g. for group slam virus reported so of course well we are concerned about the seris as well as our west swine virus he said and any infrared that ara-c. but otherwise saw it reminds us settle we could we should remain vigilance and be aware of this bet friends are those that have the potential to
cause a similar pandemic as the coronavirus now well it's very difficult to to say back to all is it or is it any more in friend of ours he sister asa lion virus isa has a potential we only don't know which maurice would jump out and cause the next in friends of him then. how disease do these viruses transmits give us an idea. well sea surface why virus is as amounting could in friends are a sweetening set to could infect humans bar ethically just a reason place there was a human infection of swine virus is reported from germany was this is a slam virus infection in there in a child who had to sit there and to come back to his pigs so he's typo's them out kicking infection where occurs from time to time. but until the cyrus develops.
efficient human to human chess mission well it has spread his ear but to said let's not append any to what it is causing. one thing 3 out of 5 new insects is diseases that emerge originate from animals wherever you see the biggest risk for the transmission of pathogens from animals to humans. yeah of course well anymore where is a vast reservoir only in viruses so sarah sees circulating in morse's and most has a silent plea what in and more sweetness and more what they want to present it is easy but if aware of so sabera sees a jump rope that species the area infecting human and also well causing sufficient efficient human to human transmission then it'll be
a problem problematic so what we really need to look into is the human animal interface where to be alert when to stage what is possible any virus he said jumping out front end was species went to humans so that we could pick those up and of course so well other efforts into under the law to help us on bryna when we talk about the animal human interface what sort of role do what markets play when it comes to the transmission of these viruses well human and more interface of course a lot oh well well from certainly aware markets a wet market to what is wound zos and also the assa where as you are see as a agriculture amount well for example as a backyard was a backyard poetry well as well so i see what we've been doing is that we said. no i improve oh my rock we stray cats it's a practice what
a human then my interface is a brick her chair set terrorists etc so i think what is it the other efforts need to be done in parallel with street gets a word that went market where becky at as well as those were commercial farming etc . and now it's time for our resident coronavirus expert here is our science correspondent derek williams answering your questions about covert 90. people here at a symptomatic carry the same amount of viruses people who show symptoms. spread from a decent to matic or present a matic patients is one reason covert 19 it has moved with such such lightning speed to our populations live viable sars close to it is clearly being shared by people who often show no symptoms of the disease when they when they test
positive for it so so we know they're playing a role in transmission much more of a role than they did for example during the sars epidemic when when patients were most infectious 5 to 10 days after they began showing symptoms the european centers for disease control say it's difficult to quantify how contagious asymptomatic people are because studies simply don't agree but the general consensus appears to be that they're less contagious than patients with symptoms or recent dramatic patients people who are going to get sick but just don't know it yet however there's also growing evidence that there are no significant differences in viral loads between the groups so to sum it up asymptomatic people appear to carry just as much of the virus as someone with symptoms but they seem to be at least
a little less likely to spread it. and of course you can post your questions to derek on our you tube channel if you'd like to keep up with the latest developments on the coronavirus spend then we do subscribe to our newsletter just log on to w dot com slash corona stash newsletter. and the coronavirus crisis is having a major impact on millions of hiv patients who are reliant on lifesaving drugs it's estimated that nearly 40000000 people across the world are living with h. i.v. although there is no cure for the disease that causes aids anti-retroviral medication helps control it the covert $910.00 demick is interrupting drug supply lines leading the u.s. to war and the long term disruptions could result in an additional half
