Obama declares swine flu a national emergency

Obama declares swine flu a national emergency

WASHINGTON – President Barack Obama declared the swine flu outbreak a national emergency, giving his health chief the power to let hospitals move emergency rooms offsite to speed treatment and protect noninfected patients.

The declaration, signed Friday night and announced Saturday, comes with the disease more prevalent than ever in the country and production delays undercutting the government's initial, optimistic estimates that as many as 120 million doses of the vaccine could be available by mid-October.

Health authorities say more than 1,000 people in the United States, including almost 100 children, have died from the strain of flu known as H1N1, and 46 states have widespread flu activity. So far only 11 million doses have gone out to health departments, doctor's offices and other providers, according to the Centers for Disease Control and Preventionofficials.

Administration officials said the declaration was a pre-emptive move designed to make decisions easier when they need to be made. Officials said the move was not in response to any single development.

Health and Human Services Secretary Kathleen Sebelius now has authority to bypass federal rules when opening alternative care sites, such as offsite hospital centers at schools or community centers if hospitals seek permission.

Some hospitals have opened drive-thrus and drive-up tent clinics to screen and treat swine flu patients. The idea is to keep infectious people out of regular emergency rooms and away from other sick patients.

Hospitals could modify patient rules — for example, requiring them to give less information during a hectic time — to quicken access to treatment, with government approval, under the declaration.

It also addresses a financial question for hospitals — reimbursement for treating people at sites not typically approved. For instance, federal rules do not allow hospitals to put up treatment tents more than 250 yards away from the doors; if the tents are 300 yards or more away, typically federal dollars won't go to pay for treatment.

Administration officials said those rules might not make sense while fighting the swine flu, especially if the best piece of pavement is in the middle of a parking lot and some medical centers already are putting in place parts of their emergency plans.

The national emergency declaration was the second of two steps needed to give Sebelius extraordinary powers during a crisis.

On April 26, the administration declared swine flu a public health emergency, allowing the shipment of roughly 12 million doses of flu-fighting medications from a federal stockpile to states in case they eventually needed them. At the time, there were 20 confirmed cases in the U.S. of people recovering easily. There was no vaccine against swine flu, but the CDC had taken the initial step necessary for producing one.

"As a nation, we have prepared at all levels of government, and as individuals and communities, taking unprecedented steps to counter the emerging pandemic," Obama wrote in Saturday's declaration.

He said the pandemic keeps evolving, the rates of illness are rising rapidly in many areas and there's a potential "to overburden health care resources."

The government now hopes to have about 50 million doses of swine flu vaccine out by mid-November and 150 million in December. The flu virus has to be grown in chicken eggs, and the yield hasn't been as high as was initially hoped, officials have said.

"Many millions" of Americans have had swine flu so far, according to an estimate that CDC Director Dr. Thomas Frieden gave Friday. The government doesn't test everyone to confirm swine flu so it doesn't have an exact count. He also said there have been more than 20,000 hospitalizations.

WHO: nearly 5,000 swine flu deaths worldwide

WHO: nearly 5,000 swine flu deaths worldwide



GENEVA – Nearly 5,000 people have reportedly died from swine flu since it emerged this year and developed into a global epidemic, theWorld Health Organization said Friday.

Since most countries have stopped counting individual swine flu cases, the figure is considered an underestimate.

WHO said there were 4,999 total deaths through Oct. 18, most of them in the Western Hemisphere. The figure was up 264 from a week earlier.

Iceland had its first swine flu death this week, and WHO said Sudan and Trinidad and Tobago also reported deaths from the virus for the first time this week.

In the United States, swine flu caused at least 95 children's deaths since April, the Centers for Disease Control and Prevention said Friday.

Forty-six states now have widespread flu activity, the CDC said, adding that only Connecticut, Hawaii, New Jersey and South Carolina are without widespread flu.

In London, drug maker GlaxoSmithKline PLC said children may only need one shot of its swine flu vaccine to be protected.

In its statement Friday, Glaxo said one dose was enough to boost children's immune systems to fight the virus, based on data from a trial in Spain in 200 children aged six months to 3 years.

Glaxo's finding comes after experts said they expected children would need two doses, since their immune systems are weaker than those of adults. Last week, rival vaccine maker Sanofi Aventis said children would likely need two doses of vaccine against swine flu, or H1N1.

GlaxoSmithKline's Pandemrix vaccine contains an adjuvant, a chemical compound that stretches a vaccine's active ingredient and increases the human body's immune response. While European flu vaccines commonly use adjuvants, there is limited data on how safe they are in groups including children and pregnant women.

The adjuvant in Glaxo's swine flu vaccine has been used in more than 41,000 people in bird flu, swine flu and regular flu vaccines.

Swine flu vaccines in the U.S. do not have adjuvants. Some countries have ordered special stocks of vaccines without adjuvants for their at-risk populations.

While most people recover from swine flu without needing medical treatment, the virus strikes children particularly hard.

According to data from the U.S. Centers for Disease Control and Prevention, more than half of hospitalizations and nearly a quarter of deaths due to swine flu are in children and adults under 25.

An Associated Press-GfK poll found that a third of American parents don't want their children to get the swineflu shot, with many citing concerns about side effects.

Of the thousands of people who have so far received the swine flu vaccine, the most commonly reported side effects have been soreness where the injection was given and minor flu symptoms.

CDC: 76 children dead of swine flu as cases rise

CDC: 76 children dead of swine flu as cases rise

ATLANTA - Health officials said Friday that 76 U.S. children have died of swine flu, including 19 new reports in the past week — more evidence the new virus is unusually dangerous for the young.

The regular flu kills between 46 and 88 children a year, according to the Centers for Disease Control and Prevention. That suggests deaths from the new H1N1 virus could dramatically outpace children's deaths from seasonal flu, if swine flu continues to spread as it has.

CDC officials say 10 more states, a total of 37, now have widespread swine flu. A week ago, reports suggested that cases might be leveling off and even falling in some areas of the country, but that did not turn out to be an enduring national trend.

"We are seeing more illness, more hospitalizations, and more deaths," the CDC's Dr. Anne Schuchat said at a press conference Friday.

The new virus, first identified in April, is a global epidemic. The CDC doesn't have an exact count of all swine flu deaths and hospitalizations, but existing reports suggest more than 600 have died and more than 9,000 have been hospitalized. Health officials believe millions of Americans have caught the virus.

The virus is hitting young people harder. Experts believe older people are suffering from it less, perhaps because they have a bit of immunity from exposure over the years to somewhat similar viruses.

Most healthy children recover and often suffer only mild symptoms. But some have died from it, often from a second infection that moves in while the body is weakened from the flu.

Kids with asthma or chronic heart or respiratory conditions also are at greater risk for serious complications.

Experts say it's important for parents to watch their children's symptoms carefully. If a child appears to get better, but fever and a cough return, there may be a second infection. Other trouble signs are rapid or difficult breathing or bluish skin color.

Vaccinations against swine flu began this week and so far, states have ordered 3.7 million doses. Demand is exceeding supply, and people seeking the vaccination should ask their state or local health department where to go, said Schuchat, who heads the CDC's National Center for Immunization and Respiratory Diseases.

Health officials also said more data is trickling in from several clinical trials of the new vaccine, and so far no serious side effects have been reported.

Preliminary results from one study indicate that both a seasonal flu shot and a swine flu shot are effective when given during the same doctor's office visit. However, the government is not recommending that people get the nasal spray versions of the seasonal and swine flu vaccines at the same time.

The nasal sprays contain weakened, live virus, and the government doesn't have data on how a person's immune system would react to exposure to both at once, said Dr. Anthony Fauci, director of the National Institute of Allergy and Infectious Diseases.

Swine flu put many hospitalized patients into ICU

Swine flu put many hospitalized patients into ICU

One quarter of Americans sick enough to be hospitalized with swine flu last spring wound up needing intensive care and 7 percent of them died, the first such study of the early months of the global epidemic suggests. That's a little higher than with ordinary seasonal flu, several experts said.

What is striking and unusual is that children and teens accounted for nearly half of the hospitalized cases, including many who were previously healthy. The study did not give a breakdown of deaths by age.

"Contrary to the perception among many people that this influenza, novel H1N1, is mild, these data vividly demonstrate that influenza can make you very, very ill," said Dr. William Schaffner, a Vanderbilt University flu expert and spokesman for the Infectious Diseases Society of America.

"Clearly, the best way to protect yourself and your family is to get vaccine as soon as it becomes available," said Schaffner, who had no role in the study but has consulted for swine flu vaccine makers.

The study was done by researchers at the U.S. Centers for Disease Control and Prevention, working with hospitals and state and local health departments. Results were published online Thursday by the New England Journal of Medicine.

A second study released by the journal revealed that swine flu had a profound effect on intensive care units in Australia and New Zealand from June through August — winter months and the normal flu season in theSouthern Hemisphere.

"They had a 15-fold increase in ICU care. That's a 1,500 percent increase," said Michael Osterholm, director of the Center for Infectious Disease Research and Policy at the University of Minnesota. "We're still heading into our flu season. Will we see this same big increase in cases over the next several months or will we have a peak in cases in October or November?"

In the U.S. study, researchers led by the CDC's Dr. Seema Jain identified 272 patients hospitalized for at least a day from April through mid-June, when the novel virus caused its first wave of cases. That's about one-fourth of the total hospitalizations for swine flu reported during that time, but researchers only studied lab-confirmed cases and patients who agreed to be part of the study.

Three-fourths of these patients had other health problems, such as diabetes — typical of seasonal flu, too. However, only 5 percent were 65 and older; ordinary seasonal flu usually hits hardest in the elderly.

Seven percent were pregnant, even though pregnant women make up only 1 percent of the general population. Among hospitalized patients whose weight was known, 26 percent were very obese, confirming a risk factorsuggested by other information from the outbreak.

Symptoms were different — 39 percent had diarrhea or vomiting versus only 5 percent with regular flu. About 40 percent had pneumonia. Seven percent died, and all had been put on breathing machines.

About three-fourths of hospitalized patients were given Tamiflu or other antiviral medicines, although most did not get these within the two days of first symptoms, as doctors recommend. Survival appeared to be better among those who got treatment quickly.

"The use of antivirals is critical," Jain said. "Start them, start them early. The patients who are hospitalized should get them quickly."

Other experts caution against making too much of specific numbers from these early results.

"We don't know how good these numbers are. They've done a good job; it's the best that we've got," Osterholm said. "But there are deaths out there that are not being recognized as influenza — only an autopsy would pick them up. And there are likely hospitalizations for flu that were missed as flu."

The Southern Hemisphere study involved 722 patients with confirmed cases of swine flu who were treated inintensive care units. More than 14 percent, or one in seven, died. That study also found a disproportionately large number of cases in pregnant women and the very obese.
