In September, CNN's chief medical correspondent Dr. Sanjay Gupta blogged that he and his cameraman contracted what doctors believe was the H1N1 swine flu while covering the war in Afghanistan. While Gupta recovered within a few days, he noted in his
blog, "this was the sickest I have ever been." Gupta is seen here attending Time's 100 Most Influential People in the World gala at Lincoln Center in New York, May 5, 2009.
