And all countries with cases have unaffected areas. You have an opportunity to keep it that way. Prepare your people and your health facilities.
Second, detect, prevent and treat.
You can't fight a virus if you don't know where it is. That means robust surveillance to find, isolate, test and treat every case, to break the chains of transmission.
Third, reduce and suppress.
To save lives we must reduce transmission. That means finding and isolating as many cases as possible, and quarantining their closest contacts. Even if you cannot stop transmission, you can slow it down and protect health facilities, old age homes and other vital areas -- but only if you test all suspected cases.
And fourth, innovate and improve.
This is a new virus and a new situation. We're all learning and we must all find new ways to prevent infections, save lives, and minimize impact. All countries have lessons to share.
