Dear Zoltan,

I work on global health here at ONE and with your support, we've spent months raising awareness of Ebola and busting myths about how it spreads. Months spent pushing governments to make bold commitments to help end the crisis, and then holding their feet to the fire to make sure they delivered. Months spent raising our collective voices to make sure decision makers knew this was a priority, even after the disease fell out of the news headlines.

Today marks an important milestone in the fight against this disease. It's now been 42 days since the last new Ebola cases were reported in Liberia. Why is this number so important? Well, according to technical experts, this marks the official end of the Ebola outbreak in this country, even though the global fight isn't over yet.

So I wanted to let you know your voice was heard.

More than a half a million ONE members like you - from Monrovia to Madrid - signed our petition. Thousands shared our Ebola tracker to make sure governments knew we were checking their pledges matched the resources delivered. Thousands shared stories of heroic local workers on the ground and shared our video calling for urgent action.

We got calls from government officials wanting to make sure you knew that they were delivering on their promises. We delivered your name straight to the UN, and to a high-level European meeting. And last month I had the honour of delivering your name to leaders of the countries hardest hit by Ebola. And these three Presidents - President Ernest Bai Koroma from Sierra Leone, President Ellen Johnson Sirleaf from Liberia and President Alpha Condé from Guinea - wanted to say thank you for all the work you've done.
