did than these numbers suggest that the question is if you had kovi are you also immune to getting it again there was some uncertainty about this a few weeks ago but it looks as though if you've had covert you do have a degree of immunity how long does that community last we don't know so i'm going to be a little bit imprecise here and say that the actual number of people who've had kind of aid and who are immune to toe bid in any community is not fully know and because we don't think that large numbers of people have copd without symptoms we suspect that probably the number of people who have covered is as many as the number of people who have had symptoms of covidien and in most populations that does not seem to exceed 10 percent right now by well sort of the question that the that also means that the number of immunity could be higher than what we know already but at the same time you mention it already we don't know how long this immunity last in a study from the university of amsterdam says that they think immunity to reinfection from corona virus may only last 6 months that mean

we don't know whether everybody gets it so we have to continue behaving as though even if you had kovi us still at risk of getting it again and where does this leave countries like sweden or at some point also britain who were aiming for herd immunity has that approach failed. i think that the u.k. does not wish to suggest to anybody that aiming for immunity was a policy it was an idea that was suggested in a number of press briefings in months so i don't think any country in the world is actually saying we should aim for herd immunity i.e. letting everybody get in and then hoping that immunity builds up in the population the costs of doing so in terms of lives lost and in terms of overloading of health services is very great right i do not but if this policy is being used anywhere it's time and of course we all hope that ideally there will be a vaccine that as we also know that could take a while and i ask you about that in a moment but 1st a quick look at where we stand. over $130.00 research teams around the world are racing to develop a coronavirus vaccine. some are using any negat

coordinates a team of 150 volunteers who develop the kovi id app today they're presenting their project in a vip see me now to political decision makers from several african countries much about the research shows that in order to contact tracing to work we can we need to identify 60 percent of the patients as soon as they have symptoms and we need to find 50 percent of their contacts basically instantaneously if you take even 4 $56.00 days to figure out all the contacts that somebody was positive had and to to follow up with them you will be too slow to effect it's least curb the spread of the virus but the biggest problem is the insufficient testing capacity that south africa has already performed more than $350000.00. and covered $900.00 tests by far the most of any african country but now laboratories are overwhelmed and often need more than 5 days to get a result something that no effort can fix. businesses are reopening social distancing rules have been relaxed a little and people are resuming favorite rituals of order to serve a return to normal life can go on unless the coronavi

kovi id every participant can register online and will then receive a q.r. codes this can be saved to one smartphone or simply printed out as fewer than half of all south africans own a smartphone and can now use the coby id app if i'm a verified so that say i'm a taxi operate our i'm a security guard i want to scan use s. yardbirds as they come in so you can. scan the post. it shows my name it should look my picture eventually it shows that i haven't been so off test that there's no information about whether i saw patrick covered from covert what has happened in the bank and it isn't the app has sent to your location to the wallet of the user and it simply has found the address of that user by looking at the q.r. code the data is not stored centrally to address privacy concerns the data is only stored on user's phones if someone tests positive he or she can agree to sharing the anonymous data with the public health authorities and to one of the users who where the same location. coordinates a team of 150 volunteers who develop the kovi id app today they're

how long do microscopic droplets containing sars kovi to remain in the air. i touched on this question once a few weeks ago but it's time to answer it again as we now have more data on whether or not stars go to might be what's often called airborne we know the virus is transmitted by larger droplets that come out when you sneeze or cough but what about the tiny droplets called aerosols that you emit all the time when you speak could they also transmit the infection a new study indicates that they might be using extremely sensitive lasers the researchers tracked aerosols emitted by test subjects speaking and detected at least a 1000 tiny droplets a minute if those people had been infected could possibly have contained virus and those droplets remain floating in the air for 8 to 14 minutes we don't know how many viruses it takes to make someone sick but the work says at least in enclosed spaces probabilities are high that infected people could transmit the virus simply by speaking loud the testing was done in the lab of course and not under real world air circ

come and standards and european union it makes no difference and the question of the fight against kovi to the fight against corona whether you're in a hotel in as a german citizens or whether you go with a german citizens to have it there is no no no difference so what we need is now european wide common standards a kind of a certificated where people can immediately identify that this hotel is working with the european standards and fight against corona out there is what we need now to come in understanding how to answer and the challenges in madrid the same like in berlin or in so that is what we have to put on the table we need an european wide standard so what about the external board is when do you think that the continent will be free and open or should be free and open to the rest of the world . we have a very good understanding and a very good knowledge about the situation inside of the european union the numbers are clear the death rate is is it's public is transparent so we know what is going on in the european union that is not the case in africa that is not the case in the

chlorine and so we expect that this infection of tap water would be quite protective against sars kovi too but we have not seen the virus in drinking water. how are we going about enjoying some i made you mentioned chlorine so swimming pools should be safe what if i want to jump into a lake or the open sea. well what i would say is is that our biggest concern actually related to recreational activities and swimming is social distancing and we know that infection through the respiratory route through the breeding route of exposure is a very important way that people are becoming sick and so i would be more concerned about making sure that people were maintaining social distancing when they were in a pool or of lake or the ocean then i would be worried about the presence of the virus in that water but these are areas of research and that's why the water research foundation we're making sure that we get the science right in understanding both the presence of the virus and wastewater and the potential for the virus in drinking water other water supplies and their ip take about that chief e

stop kovi it is not a magic weapon against the pandemic but it's an additional tool which enables us to fight against it almost to fight against even more flexibly in the near future. where the prime minister also warned about the economy describing it is pretty dire and that's because we know france is facing a red called a recession that was a grim picture that was really nailed to the post when the unemployment figures were released this year the highest since 1996 so a record high in current levels some 4500000 people out of work here in france so it seems that france may be emerging from its lockdown chrysalis but is far from able to fly yet. charlie thank you for those details that authorities are speaking to us live from paris. and a move to defend to be his country's health care system the italian ambassador to sweden has criticized the nordic countries state epidemiologist for saying stockholm should have done better than italy. we had really thought that in a modern wealthy society in sweden we should be able to protect our elderly we thought it didn't need to be like china

as well as viral so this could be very similar in the sense that the virus that coated a virus sars kovi to might be triggering an inflammatory response but it's not very common so parents shouldn't it didn't should necessarily what i mean the pet is a guy quite a lot to worry about at the moment this seems to be something else to put on their plates. yeah i think i understand the concern i have 3 children myself there and else and but this is actually quite a rare disease in fact even in the u.s. for many years we've been tracking callous saki and we don't see more than a few dozen cases a year in the u.s. on a regular basis and the disease has been that described as you know in the u.k. and other countries in europe but not in high numbers it is unfortunately. can cause serious complications but those are all treatable and most the vast majority are treatable right so given its rarity is that should local health authorities be doing anything different when it when it comes to their guidance to about children and covered 90 well i think what we're doing is pediatricians is we're letting

this is a regular occurrence in brazil this days people burying their loved ones who died of kovi 19 the death toll in brazil continues to rise and it's now the hardest hit country in south america but in spite of the rising infections brazil's president who refers to the coronavirus pandemic as a little flu remains defiant and wants to open up the economy the nest. for staying at home for those that can is find not a problem but for those who cannot those who have an empty fridge and 3 or 4 children crying with hunger it is out of reach. going to take it there about brazil she. has been a staunch opponent of lockdown prioritizing the economy and like argentina who's precedent for a man this post one of the strictest quarantines in the world. at an annual class owns a bookstore in one of scientists this week the government authorized some shops in the city to open up. it's difficult because the economy's in very bad shape but i support what the president did we had to do it because if not the death toll would be much higher. but the possibility of a rice infections has not been disca

demanding that the government declare libertaria catastrophe and disaster kovi 19 reached latin america a bit later than other regions and while some government used the time to gear up others like brazil continue to prioritize the economy over the population's health that is how will. now a team of engineers and physicians in the u.s. has developed 2 devices that could transform the fight against code 19 the staff at the university of michigan designed a portable helmet in a so-called negative pressure tent both devices essentially prevent infected from escaping into the wide environment hospitals used to treat severely ill cope with 900 patients in negative pressure rooms to prevent further infections. is the co-inventor of those devices and found flex is an aerospace company he says there are applications beyond coronavirus treatment. even the patients who are on mental learners they can be more to this device and will use similar cases you know we can spend ventilators for most critical cases it is another relation of this negative pressure helmet which is a negative pressure can't

so precious in the midst of this crisis and as we know boris johnson was suffering from symptoms of kovi 19 as well cummings implied that he had to make that decision on his own there of course some questions about whether or not this was the moral and ethical thing to do given that cummings was behind the main message that given that was given to the country to stay at home and save lives cummings appears to have interpreted some wiggle room in the rules and the regulations and perhaps in the past few days some of already started to question whether or not they indeed should be following the rules and regulations set by the government so most certainly this is dented reputations it's most certainly undermined the government's main message and its instructions going forward. thank you that leaves barker across developments from london to talk a little bit more about all of this when bennett is the political journalist in the u.k. he is also there in london thank you time owen what do you make of what dominic cummings had to say today. i think that don't come in charge today was appeal to
