We take thousands of samples every single week, and we will continue that active surveillance right the way through.

The news today is fantastic. It gives us a new tool in our toolbox against Ebola, but it will not in itself stop Ebola.

With regard to the government of France, we rely on the government of France for a lot of technical cooperation, but as of this moment WHO has not received any financial contributions from the government of France.

No evidence yet... But we're not out of the woods yet.

Of note is the fact that while the disease has crossed the border, there has been no documented local transmission. The exposure of these individuals occurred in Congo, we haven't seen a panic reaction in the community.

The virus spreads along social networks, family networks. And identifying those social networks and ensuring that both contacts and contacts of those contacts are vaccinated is a highly effective strategy.

We believe, let me be very cautious here, we believe we are probably detecting in excess of 75% of cases - we may be missing up to a quarter of cases, we must get earlier detection of cases, have more exhaustive identification of contacts.

We'd be in a lot worse situation without this vaccine right now, but the vaccine can't protect you if you're not vaccinated.

Transmission within the healthcare setting has been a major factor driving this outbreak, unfortunately, women and children have been the unwitting victims of that reality.

Every time we have managed to regain control over the virus and contain its spread, we have suffered major, major security events, we are anticipating a scenario of continued intense transmission.

It's quite a focused amplification of disease in a very specific geographic area, but the disease there has risen because of lack of access to that community, we've fallen behind in starting vaccination rings.

We seem to be very much caught in the headlines that there is nothing we can do, it's inevitable that we will going to see these waves and it's inevitable that hospitals will fill up and inevitable that the graveyards are going to fill up, it's not inevitable, it can be stopped, but it's going to take yet another effort from communities that are exhausted.

The system is considerably pressurized right now.

I'm all about forgiveness, but when you sit there, and you say you didn't make a mistake... that calls into question how you are going to represent me.

I'm always very afraid in any process where the conclusions start looking for the evidence to support them, and we're dealing with a lot of that in the last few days around her, the difficulty, I think -- and I think we have to say this quite plainly -- all hypotheses are on the table, and it is definitely too early to come to a conclusion of exactly where this virus started either within or without China.

It's not as if nature wasn't telling us to be careful, to watch out, to get ready.

In Sweden, Anders Tegnell and the team there have done a good job.

It's tried to rely on individuals and communities to comply with the advice of government and it has tried to avoid imposing mandatory lockdowns, mandatory separation of individuals, in Sweden, Anders Tegnell and the team there have done a good job.

I think science and government have a job to do that is to make the case. I think communities and people have a job to do, which is to listen to that case, and hopefully the result of that will be a widely accepted successful vaccine that could bring The Covid-19 pandemic to an end.

We are grateful for and continue to engage with our technical counterparts in The United States on all matters related to science and public health.
