U.S. officials said on Wednesday morning that swine flu has killed a 23-month old child in Texas, the first U.S. flu death. The number of confirmed U.S. swine flu cases rose from 45 to 66 on Tuesday as health officials warned that at least some American fatalities are likely.
The number of U.S. cases remains small compared with the outbreak's epicenter, Mexico, where about 150 people are reported to have died from the new, highly contagious viral strain.
