The covert 900 pandemic is said to have jumped from animals to humans starting with pangolin send 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 sauce coast to virus works kovac 19 began in animals could the answer to finding a vaccine for the corona virus also dying from. Welcome to you covered 19th special here on news America Johnson 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 the 900 suggests that sars cove 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 facts. Head of the naacp spot center in the german town of bag gets a lot of anxious queries and. They found viruses related to the corona virus in chinese bats and said parts of the virus and of pasta to humans but its not that simple. There intermediate hosts and we dont know their identity yet are native bots and nothing to do with us. Just warns against taking nest boxes down out of fear bats are vital for our ecosystem in areas like pest control in 2007 together with the virologist christian 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. Do that was and is a bunch 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. Run opposition. 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. Have also been experimental infections of ferrets in hamsters and in rabbits 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 with 19 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 coburg 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 record dog the pangolin and the civil. But so far there are only indications not Firm Evidence florian gloats of house hopes that there will be certainty soon meanwhile the knocked out center has reopened and is planning an exhibition on bats on 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 to must. We just seen in this report he of course is of iraq a just 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 establish to the animal model and forecasting 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 they are susceptible to replicate to multiply the virus states 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 we did 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 recovered from the 1st infection they have a very solid immunity and they completely resist the 2nd infection after he beaks we tested them in a debate that theyve seen preparation which didnt really work or well we have tested one of the candidates scenes which is a better big scene that we tested which has been developed by didnt Maximillian University community i cant tell you about the final resolved 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 cap stocks they can catch the virus lifestyle 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 the cells or into 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 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 can be trolled modeling data by 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 do you do to us as humans so whether we have a direct line in direct harm and then 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 viruses we would actually not be here they are the major drivers of nutrient turn over for example indeed 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 that lie to cope with 19 that weve heard that many times now isnt the 1st soul knows this it probably isnt the last what can we learn from this one. Its definitely not the last in it 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 we will probably never be able to prevent all rejections 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 the rest early as possible and then also do their controlled infection at this very early stage 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 other ok a professor i met in lighter thank you so much for your time and to stay healthy as always you are a common yourself as well. Well time for your questions now and that means over to a science correspondent derrick williams. What is the size of the coronavirus in microns. 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 metres to make a single millimeter now the small ones that is a virus is much smaller its down in whats called the nanometer range a 1000 nanometers makes up a single microcomputer 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 9000 special today we want to leave you with beautiful images of very happy dolphins off the coast of south california thanks for watching. Grand visions.
