I've spent a lot of time this weekend trying to find reliable local news sources in Guinea, and in general the results are discouraging.
The government's own website appears to be well and truly offline. So nothing from the Ministry of Health. I did find the Guinean Embassy in the US, but it has no Ebola news and its own links to Guinea are few and inadequate. It does offer Guinee News, however, which is running a couple of reports on Ebola (in French).
ABYZ News Links has a long list of online media in Guinea, but many of them are effectively dead. The only one so far useful is Le Jour, which provided the first confirmation of Ebola, but it doesn't seem to publish on Sundays. Media in neighbouring countries like Sierra Leone and Liberia are much better.
Among more generic resources, AllAfrica.com has a health page with a few Ebola reports. ReliefWeb's Guinea page has several, but none posted today. Go to Google Advanced Search and search for Guinea Ebola, sorted by date, and you'll find the most recent posts worldwide—but they tend to be mere repeats of news-service reports.
For a consecutive, frequently updated account of the outbreak, FluTrackers is far and away the best resource, but even those dedicated newshounds are relying largely on news services like Reuters. But I'm sure that they're looking for closer sources, just as I am. As they become known, I'll post them here.
