Wow just wow on Doc T’s comments in response to reporter asking about the difficulty of contact tracing. To see and hear him speak about it directly is even more powerful than this transcript excerpt could ever be:

Yes. Hi. I wanted to ask this question to the entire panel. Last week, Anthony Fauci of NIH has said that contact tracing is becoming increasingly difficult at this stage of the pandemic. Do you think that as infection spreads in most countries, it is still possible to use contact tracing as a effective way of mitigation? Thank you.
Dr. Michael Ryan: (

I think yes, but it’s very dependent on the background intensity of transmission. In situations where there’s very intense community transmission, and large numbers of cases every day, it’s very hard to get on top of case isolation alone, nevermind the contact tracing. So countries may need to make some choices on that regard. But what has happened for those countries who have been effective, those countries who stuck with contact tracing and isolation or quarantine and of contacts, have found then as the number of cases drops, that they can catch up on the contact tracing, and improve.
The difficulty has been for many countries who gave up entirely on contact tracing now having to pick that up, now having to scale up the architecture of public health surveillance as they’ve opened up societies and decreased the public health and social measures on the restrictions of movement. It’s quite tough for the public health system to catch up, and it takes time for it to do so. And the Director General said many, many times during this period of so-called “lockdowns” that this was precious time to prepare. Not only were public health and social measures having an impact on transmission, they were also clearly having a negative impact on social and economic life, and that this precious opportunity needed to be taken.
And we’ve seen in countries who have really beefed up their capacity to do contact tracing, isolation, quarantine, testing, and all of the things the Director General spoke about, they have done well.
So, yes, contact tracing, public health surveillance is a key part of a package of activities. The DG has said it. If individuals and communities can sustain the physical distancing, the hygiene, the mask-wearing, and the other things that are appropriate and advised by local government, if the public health system can continue to track and trace cases, yes, we should see a situation where the disease comes under control. And many countries have proven that. That is not supposition. Many, many countries, through applying a comprehensive strategy, have reached a very low level of virus transmission in their countries. But always have to remain vigilant in case there are clusters or small outbreaks. We’ve seen those situations arise in Germany. We’ve seen those situations arise in Singapore and Japan, in Korea, in China, and other countries.
And, again, it’s in those situations where your public health surveillance and your contact tracing and your ability to investigate clusters really comes into its own. And where you’ve really seen the advantage of public health and public health architecture is that ability to pounce on disease. What you have to do is push the disease down to the lowest possible level, and communities have made a huge sacrifice for that happen. They’ve stayed at home, they’ve stayed away from their families. They’ve contributed tremendously to suppressing-
They’ve contributed tremendously to suppressing infection. And what public health authorities have needed to do is to put in place the right public health surveillance in order to take advantage of that. So as the restrictions are lifted and as we see small clusters appear, the public health authorities can react quickly and suppress that infection again. And a great credit goes to countries like Germany, like Japan, like Korea, and others who’ve really focused in on that function of the system. They’re able to use a multifaceted approach. They’re able to sustain community commitment to the process. High levels of community acceptance, high levels of community compliance, high levels of community understanding linked to a strong public health intervention and a strengthened public health and health system. It works.
It’s not a guarantee of success but what we’ve seen is that countries that apply a comprehensive sustained strategy with their communities on board make progress. There are no guarantees with epidemics, but this right now is the best package of activities that countries have shown again and again can lead to us arriving at a situation where we can live with this virus.
Dr. Maria Van Kerkhove: (

I just want to add two points to what Mike has said. One is that it can be increasingly difficult to apply this comprehensive approach as transmission increases. But it’s not one activity alone. It is not contact tracing alone. It is not case finding alone. It is not physical distancing alone. You’ve heard the Director General, you’ve heard us say this all the time. But it’s worth repeating because there tends to be a focus on a particular intervention but it needs to be all of the above. And with an empowered community, with an engaged community, with listening to the community and having the community listen and adhere to the public health measures that are in place, this can be done. And so it can be increasingly difficult but what we have seen is in countries that have been in an overwhelming situation, they’ve prioritized these activities, these interventions into specific areas within the countries where transmission seems to be the highest intensity, perhaps related to a super spreading event or a particular cluster, and bringing that transmission down from an overwhelming situation to clusters of activity and from clusters of activity to chains of transmission.
And the other point is, is that it can be turned around. Again, many countries are seeing situations where they’re feeling completely overwhelmed, and we have seen many countries demonstrate that you can turn this around. You can bring transmission under control. It is very, very difficult, but again, prioritizing the work, prioritizing interventions to where it’s needed most, bringing situations under control where you can get a quicker gain and then focusing on higher areas of intensity. These approaches in countries need to be administered at the lowest administrative level as possible to bring situations under control to as many places as you can as quickly as you can. But it can be turned around. And we wouldn’t be saying this unless we’ve seen it happen. And unless we’ve seen countries demonstrate this repeatedly in multiple regions across the globe.
Dr. Tedros: (

Yeah. Thank you. I think this is very important and I would be happy to add my voice to my colleagues, Mike and Ryan, Mike and Maria. Mike and Maria. Mike Ryan, my general is a very humble servant of humanity. And he wouldn’t tell you what the real stories are regarding contact tracing. I know contact tracing is difficult and I agree with you our colleague, our friend who asked this question. And I know and I understand if countries say contact tracing is difficult. But if you want to try difficult, probably add contact tracing the number of cases. You trace with a situation which is dire to your life. Meaning try it in a place like North Kivu in DRC where 20 rebels operate, armed rebels, and where security is not there. Where your own security is precarious. And when Mike Ryan was leading the whole effort, he was in DRC North Kivu for several months. When there was engagement between different warring parties almost every single day.
And when you would do contact tracing of 25,000 a day despite that security situation. He didn’t send me actually, somebody sent me from the front lines, Mike Ryan wearing the helmet bulletproof, and also the jacket bulletproof and going to communities to do contact tracing and the rest, because he had no option. If you can do contact tracing in that condition, risking your life and he’s the most senior person in terms of emergency response, one of the most senior. Doing contact tracing in a stable and peaceful place wherever it is in many countries, should that come as even an issue? I’m just asking. If there is a single failure for many of our countries to really not hunt down this virus is our failure in contact tracing because we have lame excuses saying it’s too many and it’s very difficult to trace because there are too many. Trust me there is no too many even in a war situation.
If contact tracing helps you to win the fight, you do it even risking your life or get about a place where there is peace. The reason I’m saying this is we don’t tell or we don’t talk about the stories of a simple human being like Mike Ryan who would do this in a situation that risked his life. So if you want to know if contact tracing is difficult, then I will send you his picture in his bulletproof helmet and bulletproof jacket because he believed that he had to do everything to stop the Ebola and to show that saving lives actually needs that level of commitment.
So my answer is just brief. I explained and hopefully that you will understand why I said why I will say the simple phrase because I want you to understand the background. Trust me, no excuse for contact tracing. If any country is saying contact tracing is difficult, it is a lame excuse. Thank you.”
