A mild first wave of flu pandemic could reduce deaths from a future outbreak of more severe infection, a new analysis suggests.
A review of the effects of the 1918 flu pandemic on American soldiers and British sailors and civilians found that people who were infected during the first, milder spring and summer wave had a 35 percent to 94 percent lower risk of catching the more severe strain than those who weren't infected earlier.
How much do voters need to know about a presidential candidate's health, and what information should politicians be obligated to share?
