Oh, and he’s 14 years old.

Feel free to read that again.

Tony Hansberry II is a ninth-grader who, as it happens, will be presenting his findings today before an auditorium filled with doctors just like any of his board-certified - and decades older - colleagues would. He would say he was following in the footsteps of “Doogie Howser, M.D.” - if he weren’t too young to have heard of the television show.

Instead, he says that his remarkable accomplishments are merely steps toward his ultimate goal of becoming a University of Florida-trained neurosurgeon.

“I just want to help people and be respected, knowing that I can save lives,” said Tony, the son of a registered nurse mom and an African Methodist Episcopal church pastor dad.

To be sure, he had some help along the way, but, then again, most researchers do. The seeds of his project were planted last summer during his internship at the University of Florida’s Center for Simulation Education and Safety Research, based at Shands Jacksonville.

CDC has implemented its emergency response. The agency’s goals are to reduce transmission and illness severity, and provide information to help health care providers, public health officials and the public address the challenges posed by the new virus. Yesterday, CDC issued new interim guidance for clinicians on how to care for children and pregnant women who may be infected with this virus. Young children and pregnant women are two groups of people who are at high risk of serious complications from seasonal influenza. In addition, CDC’s Division of the Strategic National Stockpile (SNS) continues to send antiviral drugs, personal protective equipment, and respiratory protection devices to all 50 states and U.S. territories to help them respond to the outbreak. The swine influenza A (H1N1) virus is susceptible to the prescription antiviral drugs oseltamivir and zanamivir. This is a rapidly evolving situation and CDC will provide updated guidance and new information as it becomes available.

NEW YORK---- New York City was dealing with a growing public health threat Sunday after tests confirmed that eight students at a private Catholic high school had contracted the same strain of the swine flu that has ravaged Mexico. Some of the school's students had visited Cancun on a spring break trip two weeks ago.

New York officials previously had characterized the cases as probable, but Centers for Disease Control and Prevention confirmed that it was swine flu, Mayor Michael Bloomberg said.

About 100 students at St. Francis Preparatory School complained of flu-like symptoms; further tests will determine how many of those cases are swine flu.

Bloomberg stressed that the New York cases were mild and many are recovering, but said that some family members of students also had flu symptoms, "suggesting it is spreading person to person."

He said that the virus likely came from Mexico, although that has not officially been determined.

"We do know that some of the students from the school had a spring break in Mexico," Bloomberg said, surrounded by top city officials and members of Congress. "It is most likely to be brought back from Mexico, but nobody knows."

Federal health officials said Sunday that 20 swine flu cases have been reported so far in New York, Ohio, Kansas, Texas and California. Patients have ranged in age from 9 to over 50. At least two were hospitalized. All recovered or are recovering.

In Mexico, health officials say a strain of swine flu has killed up to 86 people and sickened 1,400.

New York officials said the flu strain discovered in the patients here is the same strain as in Mexico, though all the New York cases are mild.

St. Francis is the largest private Catholic high school in the nation, with 2,700 students. The school canceled classes on Monday and Tuesday in response to the outbreak.

Parent Jackie Casola said Sunday that her son Robert Arifo, a St. Francis sophomore, told her on Thursday that a number of children had been sent home because of illness. On Friday, he said hardly anyone was in school.

Casola said she expected to keep him home from school on Monday, even if it was open. He hasn't shown any symptoms, but some of his friends have, she said, and she has been extra vigilant about his health.

"I must have drove him crazy, I kept taking his temperature in the middle of the night," she said.

In New York, state infectious-diseases, epidemiology and disaster preparedness workers have been dispatched to monitor and respond to possible flu cases. Gov. David Paterson said 1,500 treatment courses of the antiviral Tamiflu had been sent to New York City.

The city health department has asked doctors to take extra precautions and test patients who have flu symptoms and have traveled recently to California, Texas or Mexico. Bloomberg and health officials also urged people to cover their noses and mouths when they sneeze and cough, and not to leave the house for two days after the symptoms disappear.

Investigators also tested six children who fell ill at a day care center in the Bronx. Five of the tests came back negative and the sixth was inconclusive. Two Manhattan families contacted the city, saying they had recently returned ill from Mexico with flu symptoms, New York City Health Commissioner Thomas Frieden said. Those cases were not found to be swine flu.

Frieden said New Yorkers having trouble breathing due to an undiagnosed respiratory illness should seek treatment but shouldn't become overly alarmed. Medical facilities near St. Francis Prep have already been flooded with people overreacting to the outbreak, he said.

"The bottom line is there is an outbreak at St. Francis school and we are monitoring that outbreak very carefully," Bloomberg said.

One commuter at Penn Station said she was concerned about the outbreak.

"It's something to be worried about, because we've got three major airports here," said Diani Wilverding of Linden, N.J.

In Ohio, state health officials said a 9-year-old boy who recently traveled to Mexico on vacation with his family has a confirmed case of swine flu and is recovering at his home. Officials do not know if the boy has the same strain linked to the deaths in Mexico, health department spokesman Robert Jennings said.

Kansas health officials said Saturday that they had confirmed swine flu in a married couple living in the central part of the state after the husband visited Mexico. The couple, who live in Dickinson County, weren't hospitalized, and the state described their illnesses as mild.

"Fortunately, the man and woman understand the gravity of the situation and are very willing to isolate themselves," said Dr. Jason Eberhart-Phillips, the state health officer.

Swine flu is a respiratory disease of pigs caused by type A flu viruses, the CDC's Web site says. Human cases are uncommon but can occur in people who are around pigs. It also can be spread from person to person. Symptoms include a high fever, body aches, coughing, sore throat and respiratory congestion.

At least nine swine flu cases have been reported in California and Texas. The most recent California case, the state's seventh, was a 35-year-old woman from Imperial County who got sick in early April. She had no known contact with the others.

Health officials are concerned because people appear to have no immunity to the virus, a combination of bird, swine and human influenzas. The virus also presents itself like other swine flus, but none of the U.S. cases appear to involve direct contact with pigs, Eberhart-Phillips said.

People cannot contract the virus from pork products that are properly handled and prepared, however, according to the World Health Organization.
