MEXICO CITY – A unique strain of swine flu is the suspected killer of dozens of people in Mexico, where authorities closed schools, museums, libraries and theaters in the capital on Friday to try to contain an outbreak that has spurred concerns of a global flu epidemic.
The worrisome new virus — which combines genetic material from pigs, birds and humans in a way researchers have not seen before — also sickened at least eight people in Texas and California, though there have been no deaths in the U.S.
"We are very, very concerned," World Health Organization spokesman Thomas Abraham said. "We have what appears to be a novel virus and it has spread from human to human ... It's all hands on deck at the moment."
The outbreak caused alarm in Mexico, where more than 1,000 people have been sickened. Residents of the capital donned surgical masks and authorities ordered the most sweeping shutdown of public gathering places in a quarter century. President Felipe Calderon met with his Cabinet Friday to coordinate Mexico's response.
The WHO was convening an expert panel to consider whether to raise the pandemic alert level or issue travel advisories.
It might already be too late to contain the outbreak, a prominent U.S. pandemic flu expert said late Friday.
Given how quickly flu can spread around the globe, if these are the first signs of a pandemic, then there are probably cases incubating around the world already, said Dr. Michael Osterholm at the University of Minnesota.
In Mexico City, "literally hundreds and thousands of travelers come in and out every day," Osterholm said. "You'd have to believe there's been more unrecognized transmission that's occurred."
There is no vaccine that specifically protects against swine flu, and it was unclear how much protection current human flu vaccines might offer. A "seed stock" genetically matched to the new swine flu virus has been created by the U.S. Centers for Disease Control, said Dr. Richard Besser, the agency's acting director. If the government decides vaccine production is necessary, manufacturers would need that stock to get started.
Authorities in Mexico urged people to avoid hospitals unless they had a medical emergency, since hospitals are centers of infection. They also said Mexicans should refrain from customary greetings such as shaking hands or kissing cheeks. At Mexico City's international airport, passengers were questioned to try to prevent anyone with flu symptoms from boarding airplanes and spreading the disease.
Epidemiologists are particularly concerned because the only fatalities so far were in young people and adults.
The eight U.S. victims recovered from symptoms that were like those of the regular flu, mostly fever, cough and sore throat, though some also experienced vomiting and diarrhea.
U.S. health officials announced an outbreak notice to travelers, urging caution and frequent handwashing, but stopping short of telling Americans to avoid Mexico.
Mexico's Health Secretary Jose Angel Cordoba said 68 people have died of flu and the new swine flu strain had been confirmed in 20 of those deaths. At least 1,004 people nationwide were sick from the suspected flu, he said.
The geographical spread of the outbreaks also concerned the WHO — while 13 of the 20 deaths were in Mexico City, the rest were spread across Mexico — four in central San Luis Potosi, two up near the U.S. border in Baja California, and one in southern Oaxaca state.
Scientists have long been concerned that a new flu virus could launch a worldwide pandemic of a killer disease. A new virus could evolve when different flu viruses infect a pig, a person or a bird, mingling their genetic material. The resulting hybrid could spread quickly because people would have no natural defenses against it.
Still, flu experts were concerned but not alarmed about the latest outbreak.
"We've seen swine influenza in humans over the past several years, and in most cases, it's come from direct pig contact. This seems to be different," said Dr. Arnold Monto, a flu expert with the University of Michigan.
"I think we need to be careful and not apprehensive, but certainly paying attention to new developments as they proceed."
The CDC says two flu drugs, Tamiflu and Relenza, seem effective against the new strain. Roche, the maker of Tamiflu, said the company is prepared to immediately deploy a stockpile of the drug if requested.
Both drugs must be taken early, within a few days of the onset of symptoms, to be most effective.
Cordoba said Mexico has enough Tamiflu to treat 1 million people, but the medicine will be strictly controlled and handed out only by doctors.
Mexico's government had maintained until late Thursday that there was nothing unusual about the flu cases, although this year's flu season had been worse and longer than past years.
The sudden turnaround by public health officials angered many Mexicans.
"They could have stopped it in time," said Araceli Cruz, 24, a university student who emerged from the subway wearing a surgical mask. "Now they've let it spread to other people."
The city was handing out free surgical masks to passengers on buses and the subway system, which carries 5 million people each day. Government workers were ordered to wear the masks, and authorities urged residents to stay home from work if they felt ill.
Closing schools across Mexico's capital of 20 million kept 6.1 million students home, as well as thousands of university students. All state and city-run cultural activities were suspended, including libraries, state-run theaters, and at least 14 museums. Private athletic clubs closed down and soccer leagues were considering canceling weekend games.
The closures were the first citywide shutdown of public gathering places since millions died in the devastating 1985 earthquake.
Mexico's response brought to mind other major outbreaks, such as when SARS hit Asia. At its peak in 2003, Beijing shuttered schools, cinemas and restaurants, and thousands of people were quarantined at home.
In March 2008, Hong Kong ordered more than a half-million students to stay home for two weeks because of a flu outbreak. It was the first such closure in Hong Kong since the outbreak of SARS, or severe acute respiratory syndrome.
"It's great they are taking precautions," said Lillian Molina, a teacher at the Montessori's World preschool in Mexico City, who scrubbed down empty classrooms with Clorox, soap and Lysol between fielding calls from worried parents.
U.S. health officials said the outbreak is not yet a reason for alarm in the United States. The five people sickened in California and three in Texas have all recovered.
It's unclear how the eight, who became ill between late March and mid-April, contracted the virus because none were in contact with pigs, which is how people usually catch swine flu. And only a few were in contact with each other.
CDC officials described the virus as having a unique combination of gene segments not seen before in people or pigs. The bug contains human virus, avian virus from North America and pig viruses from North America, Europe and Asia. It may be completely new, or it may have been around for a while and was only detected now through improved testing and surveillance, CDC officials said.
The most notorious flu pandemic is thought to have killed at least 40 million people worldwide in 1918-19. Two other, less deadly flu pandemics struck in 1957 and 1968.

WHO: Mexico swine flu has 'pandemic potential'

GENEVA – An outbreak of swine flu in Mexico and the United States is a quickly evolving situation that has "pandemic potential," the head of the World Health Organization said Saturday before an emergency meeting of flu experts.

WHO Director-General Margaret Chan said the North American outbreak of a never-before-seen virus was a very serious situation.

She called Saturday's emergency meeting to consider declaring an international public health emergency over the outbreak, which is believed to have killed dozens of people in Mexico and sickened at least eight in the U.S.

The experts are also expected to recommend whether WHO should raise its pandemic alert to a higher level.

At least 62 people have died from severe pneumonia caused by a flu-like illness in Mexico, according to WHO. Some of those who died are confirmed to have a unique version of the A/H1N1 flu virus that is a combination of bird, pig and human viruses.

Mexico has closed schools, museums, libraries and theaters in a bid to contain the outbreak, which may have sickened about 1,000 people there.

"The situation is evolving quickly," Chan said at a telephone news conference in Geneva. "A new disease is by definition poorly understood.

"In the assessment of WHO, this is a serious situation which must be watched very closely."

"This is an animal strain of the H1N1 virus, and it has pandemic potential because it is infecting people," Chan said.

"However, we cannot say, on the basis of currently available laboratory, epidemiological and clinical evidence, whether or not it will indeed cause a pandemic," she added.

It is the first time Chan has convened such a crisis panel since the procedure was created almost two years ago, spokesman Gregory Hartl said.

The committee may decide Saturday that the outbreak constitutes a public health emergency, and if so, whether WHO should consider measures including travel advisories, trade restrictions and border closures.

The global body's flu pandemic alert level is now set to phase three — meaning there is no or very limited risk of a new virus spreading from human to human.

The committee "will be asked, 'should we raise the alert level to phase four or phase five,' depending on their appreciation of how far the virus has spread," Hartl said.

An increased alert level was considered likely, as initial evidence from the outbreak in Mexico indicates the virus has spread between people. Hartl said, however, that a decision would not be made Saturday.

Da li cemo i mi da dobijemo taj grip? Svakako, s obzirom na enormno beliki broj poklanih i oglodanih prasica i njihovih majki. Ono sto pretekne od ljudske vrste ce dokusuriti jagnjeci grip. Ako mene pitate, to je sasvim o.k.

Nigdje nisam cula da se svinjska gripa prenosi svinjskim pecenjem, al' svasta je moguce.

Doktor "ljubi ga majka" je ovu vest prikomentarisao sa "ovo cekam vec 2 godine", pitam sta hoce da kaze a on mi lepo objasni: kod pticijeg gripa smo imali srece sto se virus nije prenosio sa coveka na coveka vec samo sa kokoske na coveka. Ovaj svinjski je opasniji jer se prenosi sa coveka na coveka uz olaksavajucu okolnost da se prenosi kontaktom (rukovanje i ljubljenje pomenuto u tekstu) a ne vazduhom. E, kad virus bude mutirao tako (javlja mi se da ce to biti 3 faza mutacije) da se prenosi vazduhom, obrali smo zelen bostan.

TO MI JE SVE JASNO. Ali mi je nejasno da se gripa prenosi putem konzumiranja pecenog svinjskog mesa Rekla bih da je kontakt sa zivim svinjama sasvim dovoljan za ovu bolest.
Btw, nema potrebe za panikom; u SAD-u su svi oboljeli uspjesno prebrodili gripu. Smrtni slucajevi su zabiljezeni samo u Meksiku.

apsolutno se slazem s kolegom............ :ph34r:

nikako mi se ne dopada na sta ovo moze da izadje,......s tim sto je pitanje koliko su ove cifre o broju obolelih diskutabilne, jer mnogi grip preleze kod kuce bez javljanja lekaru...ne znam,...........

neka vrsta utehe je da je ovo ipak H1N1 soj na koji deluju i antivirusni lekovi i vakcine....nazalost,...virus gripa jako brzo i jako lako mutira...:).

Ista panika se dizala i oko H5N1-pticiji grip, pa se onda naglo stisala bura oko svega toga.Secam se tada da su neki naucnici rekli da ce njegova mutacija ici preko svinje jer je ona sposobna da se zarazi i ljudskim i pticijim gripom ali nisam bas sigurna da me secanje dobro sluzi.U svakom slucaju nije mi svejedno jer s tim virusima se nikad ne zna,osecas se bespomocno a taj osecaj je najgori.

jest, tako su rekli,.....al mislim da ovo nije to,.....no, ako sam dobro preracunao podatke sa WHO sajta,.....smrtnost je negde oko 7%......


heh,...gle cuda, lek izbora je Tamiflu....... :ph34r:

Samo ne dizite paniku. Mediji su tu vijest napuhali za dobrih 70% ne bi li stvorili novu senzaciju.

Tamiflu?Ne opet.A taman je kutiji koju sam spremila za pticiji istekao rok.Na stranu sto je par konzumenata pomenutog leka izvrsilo samoubistvo na veoma bizarne nacine,i sto je tada 2005god kostao sila para,moracu opet da ga potrazim po apotekama.Pa i farmaceutske kuce moraju da zarade :ph34r: :) :D

Pa definitivno ima NECEGA. Ali NECEGA ima i u tzv. obicnoj gripi od koje ponekad netko i umre, pa nitko zbog toga ne vristi. Ova gripa je uspjesno izlijecena kod svih Amerikanaca, a smrtni slucajevi su, kao sto rekoh, zabiljezeni u Meksiku gdje je vjerojatno i smrtnost od obicne gripe daleko veca nego u SAD.
A sad reci - CEGA to tocno ima, a da kod gripe inace NEMA?

Pre nego neko optuzi USA i farmaceutske kompanije za novu poshast, a vidim da se neki vec vrte oko toga, samo da primetim da je tamiflu lek shvajcarske kompanije Roche koja je gotovo 100% porodichno vlasnishtvo. Mada je lek razvijen u USA, a gde bi drugo?
