His final sparring match with his challenger. Oh all right all eyes on tennessee this evening a lets go to our washing corresponds all resound who will be following that debate for you now the candidates biden and trump facing off squaring off for the last time on the same stage before the election is what can we expect. Its certainly going to be the last big clash of the 2 and as you know President Trump is trailing behind in polls some see him behind and more than 2 digits to an extent where even allies are distancing themselves from them fearing that theyre going to be dragged down by President Trump and of course he knows something has to happen this might be his last chance he received he got a big hit by the 1st debate so we can expect him tonight to go into attack mode he will probably target joe bidens son hunter biden president tom has been working on creating such a Corruption Case here against him without evidence of course. Very likely that tonight as an attempt to attack joe biden were not going to see a performance like the one in the 1st debate as you remember that was dubbed the worst president ial debate in history because a President Trump interrupted consequently and did not let his opponent joe biden finish his sentences now there are new rules in place for tonight and that means that the 1st 2 minutes every candidate will be able to speak and the microphones of the other the other candidate will be muted during that time so it will be a very different kind of debate were going to hear and see tonight the president as weve just heard also is very clear he believes all of that is unfair he doesnt like the questions he doesnt like the moderator that also being his kind of rhetoric that he sees himself as an underdog him against the establishment and thats also something were going to witness tonight in the president ial debate now is speaking of the election on a related note there are some concerning reports of foreign interference in this years election what more can you tell us about that. Right the director of the National Intelligence d. N. I. Ratcliffe yesterday reported that iran allegedly sent out emails to voters and that were coming flash coming from far right militia groups such as the problem and we remember President Trump neglected several times to distance himself from those groups and in those mails. Voters were threatened as so we do not know a lot a whole lot more on those a lot of an answer question questions also with regards to what was actually being tried to achieve there that the in eyes is making the case that these males were sent out to damage donald trump and his campaign it could also be vice versa since these males were threatening democratic voters now if youll fortys also say theres not a lot they can do about it except going public which is what theyre doing and warning voters that they should not feel threatened about this this is just a sham and yet another attempt to mingle in the u. S. Elections all over south reporting from washington for you thank you.

Germanys Public Health body is warning that the country could face an uncontrolled spread of corona virus infections the robert Coffee Institute has recorded a new high for daily cases and is warning that covert 9000 death rates are set to rise well authorities have issued new travel warnings and are urging people to stick to the rules in an attempt to curb the spread of the virus but stricter measures could be yet to come. More than 11000 new cases in one day its the highest number of new covert 19 infections germany has reported since the pandemic began these maps show in red where there have been more than 50 new infections per 100000 inhabitants over 7 days left is a map of germany 2 months ago now to the right its clear half of germany has changed color and solutions to talk to on the situation is now very serious the number of infections is rising quickly in many places and we dont know where that number is headed but we can still slow the spread of everyone can play their part we are not powerless if we follow all of the rules conduct to bar talking while some germans are worried many a came to play their part in helping to slow the spread of the virus. Before moved by suspect we will have to face even more restrictions i think thats justified because we have to live with this pandemic somehow and you. Can be really most likely to i still feel good because im taking care of myself and if everyone does well get through it well you want the government is doing enough i hope that our people do enough thats respecting the rules keeping distance hand washing and wearing masks. And then theres ventilating rooms as well if we do it all but i hope we can get by without too much trouble over the winter. Are you ready or youre not even. Germanys Public Health body says that the majority of people dont catch the virus at work or on public transport but in private settings like parties daughter mentioned get on the desirous of threads where people enjoy coming together and where they want to get to know each other there is more intense interactions in those settings you discuss things you laugh youre having a good time then the. This naturally has a much better chance of spreading if theres an infected person present years with infection rates accelerating fast some labs will in that smaller facilities are already working at full capacity and might not be able to close with rising numbers theres also concern that more areas in germany will have to implement hotshoe restrictions again like hit in best discover the land in bavaria where schools have closed down again to cope the spread. Of it you know with some of the other developments in the Global Pandemic w h o officials.

Were being told to keep things clean. d d d through direct contact or through the air traces of corona virus can be transferred to the objects we touch and in turn transfer to us. To keep that from happening weve come up with innovative ways to avoid having to touch things. And to keep surfaces clean. Living our lives means its impossible to avoid all types of contact so we need to understand the real risks in our environments. How long does the virus remain viable in surfaces and is it ever there in dangerous amounts to surfaces pose the threat we once thought they did. And this is the covert 900 special hello and welcome to the show im Stephen Beardsley in berlin good to have you with us money shopping cards door handles just about everything we touch is getting a 2nd look these days or even a clever work around like that elevator we just saw but are our anxieties over surface contacts backed up by the research of the virus and its 5 ability to look. Weaving in and out among the commuters a london Simpang Chris has this futuristic path. Theyve been brought in by one of the british capitals Busiest Railway stations to help with the fight against coronavirus. One sweeps and mops the other uses a powerful ultraviolet light to kill microorganisms including those the coup was copied 19. Keeping coronavirus off the station surfaces is a constant battle. What we need technology were our cities have our style focusing on the hardtops points so that the automatic machines can then go and train them on dining areas and that allows us to ensure that were doing exactly what we need to do with santa concorde. Scientists have been trying to work out how long the virus remains active on surfaces for searches in australia recently tested its survival when left in ideal conditions. Metrics resembles. Humans christians. First dropped out of the forests onto. Drive. 20. Years and then resume regular wants to see if we can recover. The scientists concluded that corona virus can remain infectious on surfaces such as glass steel and polymer banknotes when kept at 20 degrees celsius for at least 4 weeks thats more or less Room Temperature however move up to 30 degrees and the virus survives for just 7 days at an even higher temperature 40 degrees celsius he remains infectious for just 24 hours. The researchers are however keen to point out that outside of their strictly controlled Lab Conditions coronavirus may find it a lot harder to survive. In the real world. Encounter someone. The real. Results like. The amounts of virus used in the study are also likely to be much greater than would be encountered in the real world nevertheless Global Health officials have taken note of the findings we use this information to look at our disinfectants the good news is that this virus can be disinfected with with disinfectants with chlorine with different types of very very quickly. And that swear the same pancreas robots come in through their work and that of their human colleagues the station stands a better chance of stopping the fire in its tracks. Im joined now by a man your goldman is professor of microbiology of brokers university in the u. S. Emmanuels good to have you with us this australian story that we just mentioned in that piece does it tell us anything relevant for normal people about how they should interact with their environments. No i do not believe so the conditions that they used for these experiments were just completely out of touch with reality. Says if. The 50 scientists set down and said what what can we devise a way to protect this virus as long as possible what can we do to extend this life time thats less what they were doing for example they did their study in the dark viruses kept in the dark viruses killed by light ultraviolet light youre already mentioned that in your broadcasts. All light has some some component of ultraviolet. They used. A material in the virus preparation. That they were aiming to imitate human secretions but they use something called bovine serum albumin bovine stands for cattle. This is a protein from cow cows and its already been published bovine serum help human protects the virus and professed from decaying. The virus is killed by being dried out they took their experiment in 50 percent humidity now thats relatively normal humidity in indoors but humidity is a variable it doesnt always stay at that a percent and its turns out that 50 percent humidity is the maximum spume in the for the virus survival. Rates are the stories dries out the dogs so its going to study it looks like the got a lot of attention obviously because of this this figure of over 28. 00 days survivability what do we know about the actual survivability of the virus under normal conditions. Everybody else has looked at it. Including including many papers that i have criticised find much much less survival the virus and surfaces. The journal of medicine paper. Found a couple of days. Other papers have found a comparable in actual human eucharist the virus finds a half life of 3 hours what we mean by half life is that extra set amount of time half the virus is dead and half remains and then same amount of time again half of what was left at that point the scar and half or mains were quarters left so you do the math and you go through 456 half lives and youre down to much much lower levels of virus. And the half life that most people have measured in one paper. Order of an hour or 2 maybe 3 hours new england journal of medicine paper and plastic and still the papers had about a 6 hour halflife i think people are overly concerned about surface transmission that theyre more worried than they should be. Yes yes i do believe that they are. Definitely more more concerned than they should be the main concern should be in what you breathe. This virus is contracted by breathing its not contracted by surfaces and in fear radically you can get it from a surface there is no case confirmed in the scientific literature with this wires has been transmitted by a surface there are 2 possible papers that suggest that but even there it could just as well have been transmitted by aerosols but the air that you breathe for says this is a study in south korea. A case in south korea where there was a misuse building of offices and residences of that loving 100 people in the building one of the this is in that building. People got sick with the corona virus and everybody in that office got sick the rest of the building almost nobody got sick. And if there had been surface transmission we would have seen a lot more in that case briefly if i may ask you just on the piece there about cleaning Solutions Like these robots to go around the station fact do you think thats helpful or is that just for peace of mind as a gesture briefly if you can. I think its peace of mind its just a gesture again of the look the problem with focusing on surfaces so the takes your focus away from it really is important which is what you breathe all right and then you will have to leave it there professor Emanuel Goldman at Rutgers University thank you so much thank you. And now its time for your questions its the part of the show where our science correspondent Derek Williams answers the questions you posted to you tube channel over there. How long does an asymptomatic person or one who has overcome cope at 19 remain a possible source of infection. Regardless of whether you have symptoms or if youre asymptomatic if youve been diagnosed with coke at 19 its important not to leave isolation until your local Health Authority says you no longer pose a danger to others and its recommended guidelines the w. H. O. Says that on average positive patients who show symptoms could be infectious for up to 10 days after symptoms 1st appear it also says patients should wait at least that long plus 3 days after theyre symptom free without any medication so a person with an average case of coke at 19 if there is such a thing should isolate a minimum of 13 days for asymptomatic people the w. H. O. Recommendation is to isolate for at least 10 days since your last positive test various National Health authorities have interpreted those recommendations in different ways there is no 0 risk scenario but as a rule of thumb people who test positive whether theyre there symptomatic or asymptomatic are no viewed as being no longer infectious after 2 weeks. Or so and corresponded their claims there and before we let you go were also learning how to incorporate social distancing into our routines well heres a school in italy thats found a novel way to bring children to class while staying safe with a socalled petty bus or foot bus thats basically a rope with distance handles the Children Wear face masks and pull their book bags alongside the system was originally designed to limit air pollution from cars but has been updated for the coronavirus era.
