WASHINGTON – The new swine flu virus is spreading rapidly around the United States and more than half of the states are reporting unusually high levels of flu-like illness at a time of year when the respiratory disease usually disappears, federal health officials said Friday.
About half of the people with flu are testing positive for the new virus, indicating it is playing a significant role in the unusual pattern of disease, officials said.
“We would be expecting to see the season to be slowing down or almost completely stopped,” said Daniel Jernigan, of the federal Centers for Disease Control and Prevention. “But what we’re seeing is there are some areas that actually have reports of the amounts of respiratory disease … that are equivalent to peak influenza season.”
The unusual activity comes as two more U.S. deaths were reported from swine flu, bringing the total in the United States to at least five. A 33-year-old man succumbed in Corpus Christi, Texas, May 6, bringing that state’s total to three, while a woman in her late 40s died in Maricopa County in Arizona last week, marking that state’s first death. Washington state had previously reported a death.
At least 173 infected people have been hospitalized across the country, including a New York school official who fell ill in the midst of a new outbreak in that city that prompted the closing of two schools.
“We know the outbreak is not localized but is spreading and appears to be expanding throughout the United States,” Jernigan said. “This is an ongoing public health threat.”
The CDC has officially reported 4,714 confirmed or “probable” swine flu cases in 47 states, and 22 states are reporting widespread flu. There could be as many as 100,000 cases around the country, Jernigan said.
“This is not something we would expect to see at this time,” said Jernigan, adding that the rising count is not simply due to doctors looking harder for cases.
Despite the spread in the United States, the CDC lifted its warning against all unnecessary travel to Mexico. So far that country has suffered the most severe outbreak, but Mexican officials predicted Friday they would bring it under control by the end of the month. The CDC said individuals with other health conditions should consult with their doctors before traveling to Mexico, because such people appear to be the most prone to serious complications from the virus.
The infected New York school administrator remained on a ventilator at the Flushing Hospital Medical Center, and his son told reporters that his father’s condition had deteriorated over the previous 24 hours.
After falling ill a week ago, Mitchell Wiener, assistant principal of Intermediate School 238 in Queens, had developed pneumonia and kidney failure, his son Adam Wiener told local television reporters. Wiener’s fever was “much worse” and he was not responding to medicine, he said. Contrary to previous reports, Wiener, 55, had no pre-existing medical conditions other than gout, the son said.
Four students at one school had confirmed cases of the virus, and more than 50 have been sent home this month with flu-like symptoms. At a second school, 29 students had visited the nurse with flu-like symptoms on Thursday, and at a third 241 students were absent on Thursday. Maintenance crews were cleaning all three schools, which were closed for a week on Thursday.
Late Friday, officials announced they were closing two more schools in Queens and another in Brooklyn for up to five days beginning Monday after documenting unusually high levels of the flu.
“The fact that we’re seeing large clusters in schools is a little surprising,” said New York City Health Commissioner Thomas Frieden, whom President Barack Obama selected Friday to lead the CDC.
Meanwhile, vaccine manufacturer GlaxoSmithKline announced Friday that four European countries have collectively placed orders for 127 million doses of a vaccine it will develop to combat the new flu strain. The four countries – Britain, France, Belgium and Finland – are ordering the doses as a precaution in the event of a widespread outbreak, said Sarah Alspach, a company spokeswoman.
Production will take about four months and will begin as soon as the manufacturer receives “seed” samples of the virus from the World Health Organization, she said. The WHO is considering whether to ask vaccine makers to begin producing a vaccine in case the virus returns in a more dangerous form in the fall.
Already, there is some controversy over the vaccine, which will include an ingredient called an adjuvant that boosts the body’s immune response. The ingredient is not licensed by Food and Drug Administration, but the agency has the power to authorize use of such products in an emergency. Some health officials and vaccine watchdog groups say the accelerants may cause a severe reaction in people with compromised immune systems, specifically swelling in the joints and in the liver.
