Viruses, more dangerous in the morning !

Viral infections seem to be ten times more virulent in the morning than at any other time of day, according to a study from the university of Cambridge, conducted in mice. The cause ? Our biological clock at the cellular level. Ten percent of our genes are affected by this clock. When we awake and some genes function in slow motion, viruses can penetrate more easily in cells and grow faster. These findings could have implications in the management of epidemics. Night workers, for example, would be the most exposed to this effect, and therefore would require treatment first. 

Ce constat pourrait avoir des conséquences dans la gestion des épidémies. Les travailleurs de nuit, par exemple, seraient en effet les plus exposés, donc les premiers à nécessiter un traitement anti-infectieux.
