The coded 900. 00 condemning is said to have jumped from animals to humans starting with pangolin and bats in china. It would be easy to demonize some animals as dirty and transmitters of a disease that can be deadly to humans but some Scientists Say they present an opportunity for better understanding how the stars cope to virus works 19 began in animals could be answer to finding a vaccine for the corona virus also. The question welcome to you covered 19 special here on news monica jones in berlin good to have you with us now we share the same planet we breathe the same air and drink the same water and often we are the best of friends humans and animals but now the pandemic overshadows our happy coexistence all Available Evidence for 900 suggests that sars co 2 is transmitted between animals and humans where do we go from here in a moment we ask an expert but 1st lets remind ourselves whether this virus supposedly came from. Their reputation has taken a battering lately since the outbreak of the noble corona virus pandemic some people are afraid of being infected by bouts. Florian. Head of the natalee spot center in the german town of bad sega bag gets a lot of anxious queries. Vantive. They found viruses related to the corona virus in chinese baths and said bats have the virus in the past to humans but its not that simple. Theyre intermediate hosts and we dont know their identity yet our native bats have nothing to do with us god its. Just warns against taking nest boxes down out of fear bats are vital for our ecosystem in areas like the. Control in 2007 together with the virologist christian toast and flora and lots of house carried out a study on the bats in the cult back caves in pots a good bag they found coronavirus in the bats there but a harmless for. Didnt was and as of a very high natural diversity of coronaviruses its not just the sars like corona virus is but also range of others too and corona viruses are not restricted to bats they exist in many mammals they even found the corona virus in a palooka whale and its not just mammals fish to. Want to buy fish and. The friedrich lefler institute on the island of reims is researching which animals carry the virus that is currently causing so much anxiety around the world. Their work takes place under high security. So far cats dogs and minx have become infected naturally now just recently it happened in to make farms in the netherlands. The votes have been experimental infections of ferrets in hamsters and rob its pretty bad i. Think it is the. Ferrets are playing their part in developing a vaccine against the corona virus farm animals like pigs have so far not become infected they appear to be not susceptible to the virus but even animals that have the corona virus do not necessarily infect people some fear with pets for example. That you follow the animals which have so far tested positive are associated with the sars coronavirus to infection or a cold 1000 illness in people that means we believe it was human to animal transmission. There is no epidemiological evidence anywhere in the world that animals be they wild animals farm animals or domestic. Pets play any kind of epidemiological role in the spread of the pathogen these animals are not identified as risk factors the pandemic thrives on direct human to human transmission. Anyone who is sick with code 19 should avoid close contact with pets so as not to infect them but which animal originally transmitted the virus to humans possible candidates are the rakuten dog pangolin under service but so far there are only indications not Firm Evidence florian gloats of hopes that there will be certainty soon meanwhile dr alice but center has reopened understanding an exhibition on bats in the virus to explain why no one has to be too afraid of the nocturnal creatures. We have someone here with us to explain a bit more professor Thomas Leiter who weve just seen in this report he of course is of our ologist and the president of the institute thats the federal Research Institute for Animal Health here in germany good to have you with us and youve been doing research on a covert 1000 vaccine using ferrets what are you finding so far. Hello from insole riggs i mean 1st of all i have to have the animal model and for testing that seems to be used in humans afterwards the animal model needs to mimic the human situation as closely as possible and we find in ferrets that there are susceptible to replicator multiplied a virus takes created and they can transmitted by they dont get sick so they are a model of asymptomatic infections that still lead to infectious change in contrast to for example harms that pastors that get sick in our 1st year yourself experiments we tested 3 different essays i mean one was an infection reading leap to an immunity which is solid enough to prevent a 2nd infection and at least in the short run we can say yes that is the case saw ferrets that recover from the 1st infection they have a very solid immunity and they completely resist a 2nd infection after he became. We tested them in a debate that theyve seen preparation which didnt really work or well we have tested one of the candidate big scenes which is a big scene that we tested which has been developed by didnt Maximillian University community i cant tell you about a finally solved yet but there are some promising results are showing that its its all still work in process but it sounds very promising already whats interesting though is i mean we saw this in a report as well that pits such as cats talks they can catch the virus lifestar seems to be immune what does this tell us about the virus and how it chooses its host. It is an interesting question there are many scientists for bio actually chasing at there is a lot of molecular modeling going on in trying to predict which animal species could be susceptible to the virus and its not just as more or less of a lock and key principle that is used by a virus is to enter cells where and organisms but unfortunately does this doesnt really match that well so for example for pigs there was the idea that there would be a good effect of all susceptible to the virus and if youre really infect them in real life theyre proved to be resistant so i think for the time being were still have to really believe they are in detroit modeling data infecting the real organism and the results could be quite different now of course especially now in times of a pandemic when we talk about viruses we talk about something bad something we must fight but we mustnt forget the viruses also play an Important Role for our ecosystem and certainly dont harm bats as weve learned is there such a thing such as a good virus and a bad virus. I mean any viruses good and bad is more i mean what they do to us as humans so whether we have a direct or indirect harm done we say they are bad and if we dont feel anything there might be good i mean viruses are the most prevalent lifeform on this planet they have to highest rate of biodiversity or genetic diversity that we know and viruses are at the basis of life as we know it or at least virus like elements and without bias as we would actually not be here they are the major drivers of nutrient turn over for example india in the oceans so far all looks just as myself just fascinating tiny little tiny in the bin beings as predicted after i called them and they are most fascinating organisms to study very well professor let me lie to covert 19 weve heard that many times now isnt the 1st soul knows this a probably isnt the last what can we learn from this one. Its definitely not the last and in fact i mean all scientists have been saying there will be another pandemic and for all we dont know where and when and which agent infectious agent would be involved what we can learn from this one here is will be another pandemic and for all we dont know where and when and which agent infectious agent would be involved what we can learn from this one here as we would probably never be able to prevent reflections from animals to humans because humans are we are biologically part of the Animal Kingdom so this is just a continuum there on the other hand what we need to be alert on has the 1st infection chains that develop so if the new agent that enters the human population learns to be transmitted efficiently from human to human these are then all local epidemics and we need to find them and detect them arrest early as possible and then also do their controlled infection at this very early stage where we can improve our pets i think i would agnostic procedures are specific and sensitive enough to detect these events but we have to be on the alert ok professor leiter thank you so much for your time and to stay healthy as always you are a coming yourself as well. Well time for youll questions now and that means over to a science correspondent derrick williams. What is the size of the corona virus and microphones. With all of these large scale animations of coronaviruses that i look at every day sometimes its hard to remember how tiny they actually are to answer this question lets 1st get the terms down micron is an old way to say micro meter which is one millionth of a meter to put that maybe in terms that we can visualize it takes a 1000 micro meters to make a single millimeter now this small ones that is a virus is much smaller its down in whats called the nanometer range a 1000 nanometers makes up a single microcontroller at around 125. 00 nanometers in diameter source code 2 is actually a pretty large virus at least among the viruses that in fact humans but it would still take 8 of them lined up to stretch a single micro metre or micron if you prefer. Hair is always used to illustrate stuff like this a human here is around 50 microns across so it would take around 400. 00 coronaviruses end to end just to span the width of a human hair you know a triple check my mouth on this one but it isnt really my strong suit i hope i got it right im sure that somebody will tell me if i did. And thats all for this edition of out in 1000 special today we want to leave you with beautiful images of very happy dolphins off the coast of south california thanks for watching. Good.
