A study of hospital patients in Singapore in the first 3 months of the pandemic showed that H1N1 patients were younger but had fewer symptoms, on average, than those with seasonal flu. Of 547 patients with novel H1N1 flu, 42% were age 6 to 18, 35% were 19 to 35, and just 6% were 51 or older. In 193 patients who had seasonal flu, the respective numbers were 16%, 21%, and 23%. Fever was more common in those with seasonal flu, but cough, sore throat, and muscle aches were more common with H1N1. Arch Intern Med
