A Smart Technology is deployed in the fight against the virus. Also accused of genocide in murdering a young girl could a trial in germany prove a landmark case in the years edis search for justice. And illustrating how to get the message across we meet artists highlighting the dangers of a virus and one of the worlds most crowded places. Back into the news are 200000 people have now died from kroner virus and the World Health Organization is sounding a warning to survivors and those pinning their hopes on it. Not striking people more than once now it says theres no evidence that those recover those who do recover develop antibodies or any immunity from repeat infections its urging against issuing what are being called immunity passports certificates to those people who recover what chile has announced that it will be the 1st country to hand them out so that people can return to work other countries are looking at tests for the presence of antibodies to help with working when to end the lockdowns and left other restrictions well from london chalons has the latest. The u. K. Is one of many countries that has been looking at the idea of immunity passports this will be a way for people or some people at least to go back to work if they could prove that they already have had covert 19 and therefore its assumed that they have an immunity i would be able to get it again or pass it on but the w. H. O. The World Health Organization is not keen on this idea for this reason well we do certainly understand the intention of trying to see who can go safely back to work who would be a ranch. Risk free or in fact the other people but unfortunately from the scientific point of view we simply dont know if the person who has been infected with. 90. 2. Gets this immunity and if it gets the immunity how long this immunity is lasting now there are always problems with the immunity passport idea to start with for one thing its very divisive if you have some people who are allowed to go back to work and some people arent at a time when most governments are trying to unify their populations and say were all in this together but this verdict from the w. H. O. That people dont necessarily have immunity anyway and also saying that the testing to prove this or not is a bit sketchy at the moment at the best well i think that kills the immunity passport idea for the moment at least until a science can suggest otherwise. Coburn is one of a team of scientists who have been investigating just how effective Antibody Test really are shes a professor of epidemiology and biostatistics at the university of California San Francisco School of medicine and joins us via skype good to have you with us on the Program Problems arise on several fronts im sure as to who to be tested and whether these tests give an accurate picture of whos been exposed to the virus so our data seem to teach us that at least some of the tests that are being used can give a pretty accurate picture our population level exposure and interaction what we dont yet know is whether these kind of the antibody. Into bodies who are only 8 with anybody that would be protective against future generally call neutralizing antibodies thats work that still needs to be done if Antibody Testing is an indication that youve sort of had the virus as such but not a guarantee that you wont get it again how do you start your sort of methodology in trying to find a treatment or a test that will cover that question. Those are. Those are 2 different questions so in terms of treatments identifying people who have the infection acutely relies on detecting the virus by p. C. R. By molecular tests and thats being implemented essentially around the world but probably not in the numbers that we need in order to make diagnosis rapid diagnosis available to all and thats what we really need to do if youre looking at treatments identifying the people who meet the treatments and then you need to Clinical Trials which are ongoing to test different treatments in terms of their clinical outcomes whether they improve their ability and mortality how do scientists. And tests. My apologies how do authorities and scientific bodies like yourself deal with that sort of type of considering that so youre dealing with a virus from correct in thinking but its life cycle the destruction of it is still something that the Scientific Community of trying to fathom. Well you were you were approaching it as a Public Health problem the way we would for example a new strain of influenza and of course thats the problem no want to have this immunity to start with to this wire us and we still dont fully understand where whether people become immune there probably isnt it that we dont understand it yet we dont know how long it lasts. And so the Antibody Tests are a tool that we can use to assess population exposure rapes and we already know that in places that are hotspots like an area outside of boston a very large number of very large percentage 25 percent or 30 percent of people who were cats were positive to these Antibody Tests its less a tool for individuals than it is for populations how were you sort of coordinating your results so what have you find with the sun to as you might say of expertise whether they are in the u. S. All in europe oil use or that are also trying to find a solution to this problem specifically for the Antibody Test that we were testing weve posted all of our Information Online what we are stating that as we test more apps age more tests and of course were in communication with other people who are developing tests. And at this point one of the problems is that there are very many casts and not enough Evaluation Data to be able to say that one test works with higher sensitivity or higher specificity than another and so thats really what were working on were trying to evaluate how well the tests work in populations and just very briefly how long do you think the process might take. Well we did this in kind of record time when i evaluated test for other diseases its taken months and we basically did this in a period of about 3 weeks to test and we tested 12 different apps ace says thats because we were able to put together a team of scientists who are unable to work on their normal work and so just dedicated all their time to doing this so i think were going to have data actually very fast compared to the way things usually go because everyone is working flat out its an emergency situation indeed mostly what happened certainly with your results in the future for the moment coming from San Francisco thanks so much for joining us on aljazeera thank you. The place where the quote of the gal is walking a significant moment trying to has gone 10 days in a row without any deaths becomes a singapore reports another 608000 new cases and now has the highest daily infection rate in Asia Sarah Clarke reports. More than 3 months after the corona Virus Outbreak the city at the original epi center is standing down some of its medical teams Chinas National Health Commission says all critically ill patients in will have recovered with the last group dispatched from hospital on saturday. The number of patients in severe in Critical Condition and we had city finally became 0 which marks a decisive victory in the battle against the virus means that the covert 1003 men in china has reached International Advanced levels. The government is now focusing its efforts on a rise in imported cases in the Northern Province of helen jan which borders russia china has recorded more than 83000 cases of the virus but a study published in the journal lancet says the numbers could be 4 times higher if they are just presenting with cold symptoms at a time of winter in china then they simply would have got infected so i had the code maybe being diagnosed with having a cold or pneumonia like symptoms and then gotten better 85 percent of cases singapore now has the highest corona virus infection right in asia its reported another spike in its daily cases the majority of new infections a Migrant Workers living in crowded dormitories medical teams have been deployed to step up testing and Health Checks and the government has extended the nationwide lockdown until june but as singapore tightens its quarantine measures vietnam is starting to lift its restrictions the streets in hanoi are still empty but some shops are reopening for business with the Health Authority there reporting no new cases this week. I observe that the governments decision instructions are very. Well thought out and logical and in recent days the outbreak has been pushed back i feel grateful for being a vietnamese citizen its a downward trend being shared in south korea which suffered the 1st major outbreak outside china its government has outlined a 2 year Recovery Plan after reporting the lowest number of cases since the peak in february but the south Korean Health minister has warned citizens to accept the reality that life wont return to normal for some time yet sarah clarke aljazeera a country one curfew has been reimposed in sri lanka until one day a big earliest because of another surge in cases restrictions have been relaxed in what workers that had low risk areas outside of the capital but often unders is following developments from colombo where more than 55000 Police Officers have been deployed to impose the curfew. Checkpoints like this door to the country or all over the 25. 00 districts this one the special task force of the police the sum of 55000. 00 Police Personnel that the Police Spokesman tells us are on the roads policing this complete lockdown over the weekend now the government had hoped essentially to start easing curfew indeed in most of the districts on monday things were eased from 5 oclock in the morning to lakes 8 oclock at night however with a huge spike in the numbers seen yesterday theyve had to clamp down once again not just in those districts but also here in the capital colombo and 4 other districts now these are the scenes this generally very busy street in newgate go to columbus suburb is teeming with people on a saturday afternoon but as you can see the only vehicles that are being stopped and searched are essential services they cause invariably lots of food deliveries Health Service workers and people like that who are the only ones who are allowed on the streets the essential services but everyone everyone else has been urged to stay put in fact 35000 more than 35000 people arrested for violating curfew more than 1000 acres being confiscated by the Law Enforcement authorities indias easing restrictions for its 1300000000 people in lockdown shops selling nonessential goods can go where you can areas considered infection hotspots such as Larger Stores and shopping malls will stop shot Health Officials have reported only 25000. 00 cases and 775. 00 deaths on friday a record of the highest want to increase infections elizabeth problem is in new delhi she says there are some caveats to easing those restrictions. In areas that are considered known hotspots we are seeing shops reopening and people heading out this comes off to the Home Ministry released a statement very late on friday night to come as something those of a surprise saying that all shops which arent in malls marketplaces are allowed to open but with social conditions like everyone has to wear face masks and gloves and still observe social distancing the gloves aspects aspect as they also said that all shops and markets in rural areas are allowed to open nearly 70 percent of indians actually live in rural areas weve had a clarification from the Health Ministry said that now baba shops and salons allowed to open because they dont sell items they Sell Services so not only essential items are being allowed to be sold but not known essential services were not seeing any easing of restrictions in places like delhi most of delhi is considered is filled rather with hotspots and were actually seeing more restrictions and other places like the Southern State of tamil nadu for instance indias most populous state of health and predation has extended the bad public gatherings until the end of june so the situation really depends on where you are in the country but certainly shops being allowed to open is a huge relief to the millions of indians again in hotspots zones who owned small standalone shops. In the us demonstrations are continuing against virus lockdowns protesters say stay at home or doesnt violate their Civil Liberties but its what the government intends to do when society does reopen thats concerning privacy advocates shepparton say has more from washington d. C. Within weeks of 911 the patriot act was passed in the u. S. With no congressional debate it allowed unprecedented surveillance with minimal oversight over american citizens the alternative the government suggested was responsibility for another terrorist attack the laundry list. Needed he had wanted for many years at the time they were sure and says the measures would be temporary but theyve been routinely reauthorized by congress yet mass surveillance proved ineffective counterproductive and the data was being used for purposes unrelated to terrorism it was only 12 years after the patriot act passed with the whistleblowing of Edward Snowden that we discovered the extent of the mass surveillance and only then was the governments bulk collection of information about americans limited now with the spread of covert 19 snowden and others so theres an opportunity to learn from the past systems to monitor everyones location at all times of being formalized in secret at the point these policies are being sought these benefits are theoretical often there is no evidence for them and they may never materialize that keep ability will exist in 3 months in 3 years and in 30 years if we allow it to be implemented today clusters of disease do need to be located swiftly and closed off and smart phone data is being used to locate those not adhering to social distancing requirements but we have few specific details on Data Collection facebook and google have been in talks with the government on sharing information they collect about us Online Advertising companies that track our movements are discussing new covert 1000 Revenue Streams the firm pal into whose Data Collection has been key to the trump ability. Gratian is Deportation Program is creating proven 1000 models for the government i think all abortions are good time for a Century Companies are seeking takes. On to their education and to set themselves up to normalize the techniques i tip ensure profits whats been called for is full transparency exactly what information is being collected by whom how long has it been kept for and how is it being used particularly by Law Enforcement agencies it is traditionally the disadvantage in society who bear the weight of surveillance right you know we talk about the color of surveillance well the color surveillance is black. And thats definitely something to be thinking about when you think about data when you think about health you know when you think about the ways in which could be used in a variety of particularly commercial context or to treat people differently when they should. The consequences of pandemic policy of a Civil Liberties go beyond and the chronic surveillance and president shows a robust debate needs to occur for policies are not good and not after she obertan see aljazeera washington has consulted on the as an independent Privacy Research firm former chief technologist of the us state federal trade commission joins me now on skype from Oakland California could have you with us on the program how worried should the ordinary american be about the tech developments in technology that would allow their phones to be used as an implement to trace them. Well so theres a mounted rush right now to find proxies for information around who is infected with the virus and who they have been in contact with and some of these proxies are things like what information you provide to our mind how telling a Doctor Services that might suggest that youre symptomatic others are things like your location or your bluetooth proximity to other people that would indicate whether youve been in contact with other people or physically close to someone else and depending on the technology and depending on approach there are different privacy considerations for example location is much more sensitive so choose states currently in the u. S. Utah and north dakota have released apps for their citizens that track their location and then well notify them if someone else was tested positive for code at that location that requires essentially for them to broadcast their location to the Public Health
