simply not functioning well anymore. experts say that's not an argument against contact tracing. rather they say it needs to be ramped up as one example of where contact tracing was working factions are on the rise again . and critics like the government reports from the city of $16000000.00 in which the corona virus is spreading. and one of the teams that are fighting to stop it was the last image on as a dentist, at least she was until the pandemic started it. she's been a contact traces since march 1 of around 35000 in turkey. gonna hear your book seen from here the size of the city cali. scary. and i sometimes wonder where this endemic is headed. but as a doctor, i have

a responsibility. i try to think positively and knowing that i help people is what motivates me and keeps me going there on a tracing team manages around 10 house calls a day. they work in shifts almost around the clock. the goal is always the same track down test and isolate those who have been exposed to someone with 19 and all of this as quickly as possible. googles 1st case today is the collects is all family. the mother recently tested positive. now the father has symptoms true. could you call it clear whether if the test is positive, gergen will also trying to trace his contacts. the whole family has to stay at home for the next 14 days. after each visit protective clothing has to be changed.

good job is time consuming and strenuous but it's worth it. she says few countries expound at their contact tracing capacity to the extent turkey did these teams with key to slowing the spread of the virus in spring health officials say. but now, like elsewhere in europe, the number off infections here is on the rise again. as in many other countries, people's vigilance here has slackened in a recent survey. more than half of the respondents in turkey said the coronavirus does not affect a worry them. and critics also blame the government for this lack of concern because the health ministry no longer reports the number of new infections every day. but only the number of symptomatic patients john uncuffed, undiano of the opposition c.h.p.

says the government is hiding. the real scope of the pandemic is thought will because will cost so slow. here in istanbul alone, the number of cases is 20 times higher than the tally from the ministry of health. i'm saying this with regret, but the figures and information we have given are not correct or units who, you know, image on is on her next house call. that she does not want to take part in political discussions. she knows the debate about the numbers, but doesn't want to get involved. that more and more people disregard the coronavirus rules frustrates her being, which is surely good. it makes me sad. we are putting so much effort into this. but what's the point? if so many act as if nothing can happen to them. and if this doesn't change, we won't see an end to this pandemic sticky because it google hopes that she will

soon be able to work as a dentist again. but she also knows that her new job will be neat it for quite a while. also be as court is director of the institute of public health it good to have you on the show. again, how important is contact tracing for your job as an epidemiologist? i think it's very important, it's a crucial step in fighting that and that makes you need to have test results. obviously the laboratories need to be in place and functioning. and then you need to have staff were actually trace track down people who may be in fact that test them and isolate them if they test positive is a very important crucial aspect. and what about these contact tracing apps? i mean, surely, we could do things. so much quicker and more effectively with these apps, but do they actually help stop code 90? there certainly is this. the issue with these apps is that they will not work on all the smartphone platforms. so you need to have

a relatively new generation smartphone plus the software, not all can afford to have a smartphone. so if not all of us have a smartphone, then it already has limitations. and so that's why it can assist the process, but it's not the solution to stop the pandemic. yeah, there's already a divide their mojo between rich and poor. what about the skeptics though? the people who just don't trust the technology? well, there's always a, you know, you have issues in terms of the data protection, which is a very important point. but i think specially here with you have been germany that did a very good job in making sure that none of personal data is actually transmitted. but of course, that is a concern, and some people may feel uncomfortable. so we need to work to really make sure that people understand the importance of having this, that should be available for all the smartphones that we are wearing. and the importance is as well that it only functions if a certain amount of people do actually download the app. that is correct. if you

don't have the, if you don't have a smartphone, will not realize that you are close to someone who may be infected and will not give that signal to you that you may be at risk of getting the infection or having a contact that is infected so it's very important that people download and work with the app, obviously that this app is actually working. and this mechanism in term terms of tracing with the app is actually functioning to be talking about the functionality and the effectiveness of these apps. why, why did we get a europe wide app at the very beginning of this crisis? that's a very good question. i think the european union is not really taking a good steps in acting jointly. so we obviously need to have a good functional european solution and we should have had a european app that if you travel to france or to spain up there, the any other european country that it works there as well. and not just within your local setting. how did it stand but managed to do such a good job of contact tracing? initially before the 2nd wave?

as you have shown, the report to have mobile teams, they're going from door to those sort of say it's a lot of manual work to trace the people who have been in contact with someone who is in fact that. and that really helps. as i mentioned before, it's a crucial step and we're doing the same job in germany. but if you reach a point where you have just too many cases, the systems just don't work anymore. you're overwhelmed with the number of cases. and no matter how well organized you are at one point, it won't be enough, you won't have enough staff, you want to have enough people on the phone. you want to have enough people on the ground where actually able to trace and test and isolate. so that's why the system works very well up to a certain threshold and then the system stops to work. so nothing's happened in germany about meds and september. so would you say germany is also overwhelmed by the situation? yes, we can only overwhelmed by the situation. so we're behind the way if you, if you wish, and we need to get in front of the wave and actually be able to test and trace. and that's why we having the measures in place to actually have the number of people

who are testing positive in the range where we can start to trace and test an isolated then, how do you see the situation developing now in the coming weeks and months? well, what we have to understand is like the so-called lockdown is not a cure, it's a reset. so to say, so you reduce the number of people who are infected to a threshold where you can act with the tracing and testing and isolating. and this soon as you open up a little bit, the number will increase again and then the point that the question is whether you can achieve a balance where you can, you are below the threshold where the can do their work. and we can trace and test, but the risk is that you go over and then we having the issue as we have right now . so the situation of the pandemic will be resolved, as soon as we have a vaccine available, and enough people who are vaccinated to be as caught director of the institute of

public health that are lynch. it's a thank you very much for joining us today. and the interesting stuff. thank you for having me. well enough from a time for you to us. the questions is our science correspondent there which colbert, 19, diagnostics are most useful from an epidemiological point of view. there are basically 3 types of diagnostics that play useful, but different roles in the fight against covert 19. the 1st 2 are for determining whether someone has the disease or not. the gold standard for doing that is what's called a polymerase chain reaction or p.c.r. test. and it works by amplifying tiny amounts of any viral genetic material available in a sample up to levels where it can be detected, although no test is 100 percent reliable and p.c.r. tests are very accurate on the downside. they're also slow and fairly expensive,

which is a drawback when numbers of cases are rising rapidly. the 2nd class of detection diagnostics called antigen tests work by detecting viral proteins directly. antigen tests are cheaper and they can deliver a result in minutes, but they're also less accurate than p.c.r. tests, which is a particular problem when it comes to what are called a false negative results. that's when people actually have the virus. but because the test says they don't, they don't isolate still the speed and low cost make antigen tests, important tools and scenarios where infections are spiking and, and a lot of people need to be tested quickly and they can often be performed on site. so, sepals don't have to be sent off to specialized labs. the 3rd diagnostic in the covert, $1000.00 pound demick, that's playing an important role is what's called a serial logical test, generally called an antibody test, which detects proteins called antibodies that form in the body. as part of the

immune response, they can tell doctors if someone wasn't fact at least in the recent past, i see a logical tests also play a key role in vaccine development since they can show whether a candidate is having the effect that we want, which is to problems the immune system to produce antibodies or williams. there i've been fizzling for any other developments on the arse. it's well website dot com slash covered 90

going read hijacking the news where i go wrong. the news is being hijacked. journalism itself has become a scripted reality show. it's not just good versus evil us versus them black and white in countries like russia, china, church, people are told, it's that simple. and if you're a journalist there and you try to get beyond it, you are facing scare tactics, intimidation. and i wonder, is that where work headed is? well, my responsibility as a journalist is to give me on the smoke and mirrors. it's not just about the premier and balance or being neutral. it's about being truthful. when he was born
