CDC: Swine Flu Outbreak "Serious"
8 Cases Confirmed in the U.S.; Global Health Experts on Alert

Swine flu has killed at least 20 people in Mexico and sickened at least eight people in the U.S., and the CDC expects more U.S. cases as the hunt for swine flu intensifies.
The eight confirmed U.S. cases are located in San Antonio, Texas, and California's San Diego County and Imperial County. Others will probably be found elsewhere, notes Anne Schuchat, MD, the CDC's interim deputy director for science and public health program.
"We are likely to find it in many other places," Schuchat said at a press conference today. "We don't think containment [of the virus] is feasible."
CNN is reporting that two cases of swine flu in Kansas are expected to be announced by the Kansas Department of Health. And New York City officials are reporting eight "probable" cases of swine flu in students at a private school in New York City. The New York City Department of Health and Mental Hygiene will send samples taken from the students to the CDC for confirmation.
The World Health Organization (WHO) has asked health departments worldwide to watch out for the virus, which is a mix of swine, human, and bird influenza viruses.
In a news conference today, WHO officials called the flu outbreak "serious," but the WHO has not yet declared swine flu to be a pandemic.
Schuchat says that so far, the U.S. cases have been milder than those seen in Mexico, where at least 59 people have died of pneumonia, according to the CDC. The WHO notes that 20 of those deaths are confirmed to be from swine flu; health officials are investigating the other Mexican deaths.
The CDC is already taking the first steps toward making a vaccine against the virus; that process takes months, Schuchat says. The CDC has also sent staff to Mexico as part of a global team responding to the outbreak.
Here are the CDC's tips for limiting your risk of catching the swine flu virus:
Cover your nose and mouth with a tissue when you cough or sneeze. Throw the tissue in the trash after you use it.
Wash your hands often with soap and water, especially after you cough or sneeze.
Alcohol-based hands cleaners are also effective.
Try to avoid close contact with sick people.
If you get sick, stay home from work or school and limit contact with others to keep from infecting them.
Avoid touching your eyes, nose, or mouth. Germs spread that way.

WHO Cites Potential for Swine Flu Pandemic
Mexico's Leader Orders Sweeping Measures As Cases Exceed 1,000

MEXICO CITY, April 25
The World Health Organization rushed to convene an emergency meeting Saturday to develop a response to the "pandemic potential" of a new swine flu virus that has sparked a deadly outbreak in Mexico and spread to disparate parts of the United States.
Health officials reported that at least eight students at a private high school in New York City had "probable" swine flu. They also confirmed three new cases -- two in Kansas and one in California -- bringing the total number of confirmed U.S. cases to 11. The president of Mexico, where the outbreak has killed as many as 81 people, issued an order granting his government broad powers to isolate patients and question travelers.
"This is a serious moment for the nation," President Felipe Calderón said Saturday. "And we are confronting it with seriousness, with all the pertinent measures."
The director general of the World Health Organization, Margaret Chan, said the "situation is evolving quickly."
"We do not yet have a complete picture of the epidemiology or the risk, including possible spread beyond the currently affected areas," said Chan, who cut short a trip to the United States so she could rush back to the WHO's headquarters in Geneva to convene an emergency meeting of expert advisers to formulate a response to the virus. It is the first time the committee has been called upon since it was created two years ago to help handle disease outbreaks after the SARS, or severe acute respiratory syndrome, epidemic.
"In the assessment of the WHO, this is a serious situation that must be watched very carefully," she said. "It has pandemic potential."
The virus, for which there is no vaccine for humans, has nearly brought Mexico City to a halt. Normally congested downtown streets in this city of 20 million were almost empty Saturday, and of the few people who ventured outside, many said they did so only out of necessity. Soldiers posted at subway stations handed out face masks to passersby from the back of armored vehicles. Some pedestrians covered their mouths and noses with scarves and rags.
"We can't escape the air," said Antonio Gonzáles, 56, who wore a surgical mask outside a public hospital. "If it was something in the food, we'd have a chance."
The Mexican government reported more than 1,300 suspected cases of the virus, which mixes animal and human strains of flu. Bars and nightclubs, schools, gallery openings and sporting events were cancelled until further notice. Authorities advised people to wash their hands regularly and avoid the customary greeting of kissing on the cheek. The government issued a decree giving the Health Ministry power to enter people's homes, close public events, isolate patients, and inspect travelers and their baggage.
The Associated Press reported that 24 new cases of the flu emerged Saturday in Mexico.
Worry and uncertainty seemed contagious. Many people had heard inconsistent reports on how many people were sick or dead, how the flu would manifest itself and which areas, if any, were safe.
"The people are disoriented. I think the government doesn't know what they are confronting," said Gonzalo Sariñana, 40, a university official from the northern city of Monterrey who was in Mexico City. "We are just guarding ourselves, waiting to hear what the government tells us to do."
Outside the General Hospital of the 32nd Zone, dozens of people wearing medical masks waited for word about relatives, some of whom had symptoms they suspected could be swine flu.
On Friday around 6 p.m., after returning from her job at the airport with Mexicana Airlines, Monserrat Montoya, 22, developed a fever, headache, aching bones and a cough, said her mother, Lourdes Resendes.
Montoya was taken to the hospital early Saturday and was put in isolation. Waiting outside the emergency room, Resendes did not know whether her daughter had tested positive for swine flu.
"This is very serious, more than anything because this hospital is not prepared for something like this," Resendes said. "There were people here from 11 at night that weren't attended to until 9 in the morning."
In remarks at a hospital opening in the southern state of Oaxaca, Calderón stressed that the flu was curable and that Mexico had sufficient supplies of antiviral medicine to deal with the situation.
The Mexico deaths are of particular concern to authorities because the victims have tended to be young, healthy adults, whereas ordinary flu mostly kills infants and the elderly.
In New York City, about 200 of the 2,700 students attending St. Francis Preparatory School in Queens had missed school earlier in the week because of flulike symptoms, prompting school officials to notify the health department.
A preliminary analysis of viral samples obtained from nose and throat swabs from nine students found that eight tested positive for influenza A. Because none matched the known H1 and H3 subtypes of human flu, they were considered "probable" cases of swine flu, said Thomas R. Frieden, commissioner of the New York City Department of Health and Mental Hygiene.
"We're concerned," Frieden said. "When we see the serious cases in Mexico, and we see it spreading fairly rapidly in one school, it's a situation that has to be monitored very carefully."
The St. Francis students had just returned from spring break, during which some may have traveled to Mexico, he said.
The WHO, after the committee met for about two hours, described the outbreak as a "public health emergency of international concern" and recommended that countries intensify their efforts to identify "unusual outbreaks of influenza-like illness and severe pneumonia."
The committee concluded that it needed more information about the outbreak before any decision could be made about raising the pandemic alert status, which is currently Level 3, meaning very limited spread of virus from person to person.
Chan stressed that a pandemic was not yet underway or inevitable, and she noted that no outbreaks had been reported elsewhere.
All of the confirmed cases in the southwestern United States -- seven in California and two in Texas -- have been relatively mild. Only one patient has been hospitalized, and no one has died, giving officials hope that the situation may not be as dire as in Mexico.
Late Saturday, state health officials in Kansas said the Centers for Disease Control and Prevention had confirmed two cases of swine flu that involved two adults who lived in the same house. Neither was hospitalized, but one was still ill and undergoing treatment, officials said. One had recently traveled to Mexico, they said.
The CDC has dispatched teams to Southern California to help state and local officials and plans to send a team to Texas. The agency is also analyzing samples from other suspected cases and taking steps that would be needed to produce a vaccine if necessary.
"We're trying to take action early before things get worse," said Anne Schuchat, the CDC's interim deputy director for science and public health. "We are worried, and because we're worried, we're acting aggressively on a number of fronts."
Stein reported from Washington.

I can't help thinking that the question becomes, is this a true medical "mystery" or is it a weaponized/engineered flu?

Never-Before-Seen Mixture of Bird, Swine, Human Flu Sickens 7 in Calif., Texas
Friday , April 24, 2009
Health officials are investigating a never-before-seen form of the flu that combines pig, bird and human viruses and which has infected seven people in California and Texas. All the victims recovered, but the cases are a growing medical mystery because it's unclear how they caught the virus.
None of the seven people were in contact with pigs, which is how people usually catch swine flu. And only a few were in contact with each other, according to the U.S. Centers for Disease Control and Prevention.
Still, health officials said it's not a cause for public alarm: The five in California and two in Texas have all recovered, and testing indicates some mainstream antiviral medications seem to work against the virus.
Dr. Anne Schuchat of the CDC said officials believe it can spread human-to-human, which is unusual for a swine flu virus.
800 Sickened, 60 Dead From Flu-Like Virus in Mexico
The CDC is checking people who have been in contact with the seven confirmed cases, who all became ill between late March and mid-April.
Because of intensive searching, it's likely health officials will find additional cases, said Schuchat, director of the CDC's National Center for Immunization and Respiratory Diseases.
CDC officials detected a virus with a unique combination of gene segments that have not been seen in people or pigs before. The bug contains human virus, avian virus from North America and pig viruses from North America, Europe and Asia.
Health officials have seen mixes of bird, pig and human virus before, but never such an intercontinental combination with more than one pig virus in the mix.
Scientists keep a close eye on flu viruses that emerge from pigs. The animals are considered particularly susceptible to both avian and human viruses and a likely place where the kind of genetic reassortment can take place that might lead to a new form of pandemic flu, said Dr. John Treanor, an infectious disease specialist at the University of Rochester Medical Center.
The virus may be something completely new, or it may have been around for a while but was only detected now because of improved lab testing and disease surveillance, CDC officials said.
The virus was first detected in two children in southern California — a 10-year-old boy in San Diego County and a 9-year-old girl in neighboring Imperial County.
The cases were detected under unusual circumstances. One was seen at a Navy clinic that participates in a specialized disease detection network, and the other was caught through a specialized surveillance system set up in border communities, CDC officials said.
On Thursday, investigators said they had discovered five more cases. That includes a father and his teenage daughter in San Diego County, a 41-year-old woman in Imperial County (the only person hospitalized), and two 16-year-old boys who are friends and live in Guadalupe County, Texas, near San Antonio.
The Texas cases are especially puzzling. One of the California cases — the 10-year-old boy — traveled to Texas early this month, but that was to Dallas, about 270 miles northeast of San Antonio. He did not travel to the San Antonio area, Schuchat said.
The two 16-year-olds had not traveled recently, Texas health officials said.
The swine flu's symptoms are like those of the regular flu, mostly involving fever, cough and sore throat, though some of the seven also experienced vomiting and diarrhea.
U.S. health officials are consulting with Mexican and Canadian health officials, and the CDC is beginning to receive samples from Mexico for testing, a CDC spokesman said. The ethnicity of the seven confirmed cases was not disclosed.
