how does the virus spread. why do we have it and when will. we just threw the tags and the weekly radio show is called spectrum if you would like any more information on the chrono lara's or any other science topic you should really check out our podcast you can get it wherever you get your pod cast can also follow us and. science. in. sweden opted against a lockdown when it came to measures against spreading cope with 19 observers watch the country closely to see whether enough of the population would eventually become immune to the disease. the strategy has arguably led to one of the highest per capita death tolls in europe calling into question the scandinavian countries

decision. 6 months into the pandemic it's still unclear when those infected with the coronavirus really are immune and how long one recent study shows steep drops in patient antibody levels within months of getting coated 19 so just how long would it take to be reinfected with a coronavirus. welcome to your cover not in special here on the news i'm monica jones good to have you with us of course we all want to be in you into sars cove too we could go about our lives without worrying about getting infected or infecting others and the key to our newly won freedom could be an immunity passport but that's highly controversial. it could be embedded in a chip card an immunity id that says the behavior has survived covert 19 or been immunized a contentious issue for political leaders. and when you take it creates
12:47 pm
a fatally false incentive to get infected deliberately in order to have more freedom afterwards it also divides our society because asia it's been i think the question of immunity has not yet been settled on a scientific level until it is we cannot introduce something like this i don't want to split the population into sick and healthy people. but health minister yet doesn't want to let go of the idea even in the face of opposition. that there are fundamentally good arguments on both sides that get as and with on the $100.00 many of our citizens feel a need to know if they've had covert 19 and there will also be countries that will demand this kind of proof. for done so far no country is seriously considering a compulsory immunity passport for incoming travelers. but iceland has discussed making a fresh negative covered 1000 test a requirement for entry. instead of
12:48 pm
a 2 week or untying one can take a test at reykjavik airport or provide a doctor statement recognized by the icelandic health ministry to me at this it is the least as compared even with. a cologne startup is already working on a digital covert 1000 passport but would use block chain technology to store a negative test result for 3 days the length of time before an infected person becomes contagious. before fame views on you have to think about it like an inner clean boarding pass that shows a fresh covert 19 test result which indicates that i don't have a virus no then i can always have it ready i keep it in my pocket for it so i can decide myself whether or not to show it and to whom as it were not going to stop people from getting tested at their own expense but we can stop them from using that to their advantage in our society to do things that others cannot under the mist of. people could have their test results and immunity passports stored on their phones but what difference would it make for night club or cinema operators
12:49 pm
for example if only a small percentage of germany's $80000000.00 plus population participates. if frankly an immunity id or passport would bring as no benefit it would be so few people not a single cinema could open up on that basis. ethics experts fear that individual health data could become less and less private well my love is this is usually it's my own decision to tell someone about the state of my health that's one of my rights as an individual but now in the time of the pandemic we see that there can be a justified public interest in finding out whether someone is sick or not. so far on opium other countries the dentist. health minister sharon wants more time for debate it's too delicate a matter to be rushed. for more i'm joined by professor thomas come apart he's the president of the german society of india knowledge and the director of the
12:50 pm
institute of immunology in you know good to have you with us well listening to this report just now i guess the big question is op people who recover from cope with 19 in the u. to the disease and does it therefore make sense to introduce and unity id. well the short answer to the 1st question is most people will be immune for some time and perhaps i'll elaborate a little bit on that and then we come to the 2nd question so. millions of people have suffered from covert 19 and until very recently there were no reports on reemergence of the disease until last week when a paper was published in the lancet infectious diseases from who han in china where . hospital workers followed people that had been ill risk who had 19 were cured have been released from the hospital and were followed up and out of 600 such people coalesce and people some were positive again on virus test that's not
12:51 pm
unexpected but 8 of these were sick again and some of these needed hospitalization that is to say that a small percentage in the range of one percent of people who have recovered from the disease may be reinfected very soon after they have recovered so an immunity id doesn't really make sense when i when i listen to that answer before we elaborate on that 1st let's establish what our immune system is actually doing because it's al of their own defense mechanism against intruders so let's take a look what happens when an unwelcome guest in this case a virus and his body. when it's infected with a novel coronavirus the body mounts an immune response so-called antigen presenting cells in just proteins from the virus and display them on their surface. this activates t. help or cells which initiate a host of immune functions they help activate cited toxic t.
12:52 pm
cells to kill already infected cells in the body and they stimulate the cells to produce antibodies that bind to the virus preventing it from infecting further cells and tagging it for destruction. the professor come out from the german society of immunology that the cases where the immune system's reaction actually caused bigger problems than the virus itself what do we know about how could $1000.00 and celebrates the immune system. code 19 code 1000 as a or to the virus is an alarm signal to the immune system and in some cases the immune system overreacts and then some of the cells that you just mentioned in your future produce cytokines transmitters and communicate with other cells and set a very very high as for a. state of alarm and that then contributes to lung failure similar to what has
12:53 pm
happened in some cases of influenza and other risk for a tory viruses like sars so the reaction to the virus can contribute to the severe form of the disease that we see in some of the patients right now is mentioned it's that there are studies out now that say that it is possible that once you've had 19 you can get it again and they said in the scenes of us studies that show that antibody levels drop rather quickly how big a role do t. cells plays and for our immunity. we know very little about tea so it's in the defense a good coby it's and against kobe 19 but we do know that they're extremely important for other respiratory viruses so we can assume that they are also important for sauce cove too and we know from sars the earlier variant off the sauce so far asus that t. cells set are detectable in the mucosal in the respiratory tract a much more long lived and probably more important in the n.t.
12:54 pm
body responses in these patients so the t. cells are extremely important to protect us against respiratory viruses like sauce of 2 and just very briefly yes or no if unity id yes or no. no ok professor i am a resident of the german society for immunology thank you so much for your time thank you. and outlets here more of your questions correspondents derek william stands ready to give some concepts. what's being done to establish the actual origin of the virus. chasing a novel pathogen back to its original source is an extremely complex but also a very important task because it provides invaluable information about about how to prevent similar events in the future the current mantra is still that sars cove

to jumped from animals to humans sometime towards the end of last year in china but we still don't know much about where or how we know that genetically it looks quite similar to other coronaviruses found in bats but but we can't yet say whether it jumped directly to us from them or if there were other intermediate host animals china has come in for criticism worldwide and in the course of this crisis not least for its perceived lack of transparency and cooperation in in looking into the origins of sars cove to but but finally last week the w.h.o. announced it was sending and advance team there to help coordinate the search into how the covert $1000.00 crisis began it's made up of just 2 of the organizations experts but i mean i guess you have to start somewhere
12:56 pm
a larger international mission is supposed to follow but there doesn't appear to be a concrete timeline yet for for wed. has anyone tested the fertility of those who have recovered from call that 19. lots of researchers are looking into this topic a quick search for the term. covert 19 and fertility in 2020 academic publications threw up 4000 hits i looked at several of those that had been most cited and and they all had one thing in common they said we don't really know yet quite recent study though from researchers in oxford that among other things looked closely at perceptor associated with the virus and reproductive system tissue from both men and women came to the cautious conclusion that at the cellular level at least prove
12:57 pm
it 19 doesn't appear to do any lasting damage or be associated with increased risk of complications that might affect fertility but the discussion of course included the kabi out that we still don't have enough data to say anything for certain. and that's all for this edition of 1000 special from wall just got to run about a section on our website at e.w. dot com for me in the team thanks for watching. spain has seen 20000 covert 1000 related deaths in both peoples how did it come to . patients away. residents of old people's home. or not. many others want justice.
