New York City officials on Wednesday reported the deaths of three more people with swine flu, and estimated that more than half a million New Yorkers may have become sick from the virus.

The latest deaths bring the city’s total to 12 since the outbreak began in late April. The city health department said that one of the latest victims was 30 to 39 years old, one was 50 to 59 years old and one was over 65.

The city also announced 102 new hospitalizations since its last report on Monday, bringing the total hospitalizations to 530.

Dr. Don Weiss, director of surveillance for the Bureau of Communicable Disease, said that what looked like a spike in hospitalizations actually represented catching up from a lag in reporting over the weekend. He said that hospitalizations were running at the rate of 35 to 40 a day, and “don’t appear to be going up or down appreciably.”
