Second confirmed death, the first of a U.S. resident, a pregnant special education teacher in Texas: Judy Trunnell. The 33-year-old gives birth to her second child via Caesarian section during her eighth month of pregnancy, in a coma whilst on life support.[93][94] Judy Trunnell had several underlying medical conditions, most notably asthma.[95][96][97] Several sailors in San Diego, California fall ill (including a sailor on the USS Dubuque, which results in the cancellation of its deployment). These are the first cases in the U.S. Navy.[98] As the low level of virulence of novel A(H1N1) in the U.S. becomes established, the CDC issues revised criteria for school closures, effectively ending widespread shutdowns.[99]
