But there is evidence that far less serious Ebolavirus infections may occur in the absence of outbreaks. The latest study was conducted in late 2007 and comprised 3415 subjects living in 14 rural villages in ...

The TWiVodrome considers the intestinal tract as an alternative infection route for MERS coronavirus, and how reduced accumulation of defective viral RNAs might lead to severe influenza. <span data-mce-type="bookmark" style="display: inline-block; width: 0px; overflow: hidden; line-height: 0;" class="mce_SELRES_start"></span>&lt;span data-mce-type="bookmark" style="display: inline-block; width: 0px; overflow: hidden; line-height: 0;" class="mce_SELRES_start"&gt;&lt;/span&gt;&amp;lt;span data-mce-type="bookmark" style="display: ...
