This is the time when employers ask sick employees to stay at home in bed when they call in to the office, because they sound so hoarse. And also the time when coworkers will stay clear of those who do come in. But then it is too late, since everyone is probably already infected by then. Randall thus suggests that this is evidence that the cold virus has evolved to spread optimally in a work place. Since the cold virus is much older than offices this is unlikely. But it will always spread better in places where many people are close together; and since we are more inside in the winter, this is the main reason why it spreads more during cold periods. However, viruses do evolve very quickly so it may not be unlikely that some of them has already adapted to our present way of living.&lt;/div&gt;&lt;/td&gt;&lt;td class='diff-marker'&gt;&amp;#160;&lt;/td&gt;&lt;td style=&quot;background-color: #f9f9f9; color: #333333; font-size: 88%; border-style: solid; border-width: 1px 1px 1px 4px; border-radius: 0.33em; border-color: #e6e6e6; vertical-align: top; white-space: pre-wrap;&quot;&gt;&lt;div&gt;In the title text Randall muses about the fact that contagiousness ends around the time when hoarseness begins.
