PostSubject: Swine Flu   Wed Apr 29, 2009 10:29 am

Copied from Wikipedia:

The new strain of influenza involved in the 2009 swine flu outbreak is a reassortment of several strains of influenza A virus subtype H1N1 that are, separately, endemic in humans and in swine. Preliminary genetic characterization found that the hemagglutinin (HA) gene was similar to that of swine flu viruses present in United States pigs since 1999, but the neuraminidase (NA) and matrix protein (M) genes resembled versions present in European swine flu isolates. Viruses with this genetic makeup had not previously been found to be circulating in humans or pigs, but there is no formal national surveillance system to determine what viruses are circulating in pigs in the United States.

The origins of this new strain remain unknown.

The earliest known human case was near a Mexican pig farm in La Gloria, Veracruz state, Mexico, that raises almost 1 million pigs a year.

Residents of La Gloria have long complained about the clouds of flies that are drawn to the so-called 'manure lagoons' created by such mega-farms. Edgar Hernandez, 4, was thought to be suffering from ordinary influenza but laboratory testing revealed he had contracted swine flu. The boy went on to make a full recovery.


Dr. Anne Schuchat, interim Deputy Director for CDC Science and Public Health, said that the American cases were found to be made up of genetic elements from four different flu viruses North American swine influenza, North American avian influenza, human influenza, and swine influenza virus typically found in Asia and Europe "an unusually mongrelised mix of genetic sequences." Pigs have been shown to act as a potential "mixing vessel" in which reassortment can occur between flu viruses of several species. This new strain appears to be a result of reassortment of human influenza and swine influenza viruses, presumably due to superinfection in an individual human. Influenza viruses readily undergo reassortment due to antigenic shift because their genome is split between eight pieces of RNA (see Orthomyxoviridae).

The current strain of swine flu can adapt to humans and spread more efficiently than previously known swine H1N1 strains. Moreover, co-infection of H1N1 swine flu and Oseltamivir resistant H1N1 season flu can lead to acquisition of H274Y by the swine flu via recombination or reassortment. Swine H1N1 with human H1 and N1 have been reported.

The 1918 pandemic strain has polymorphism from swine and human H1N1 in all eight pieces of RNA gene segments. Similar swapping of gene segments in humans co-infected with seasonal human influenza and swine H1N1 can lead to rapid evolution.

Here is a current map of the world:



Black = confirmed by death
Red = confirmed cases
Yellow = unconfirmed or suspected cases

Maybe if I get this flu I'll get super-pig powers and save the world from evil with my pig-themed gadgets.
:suspicious:

Seriously, though, this is a big thing. It'll be the next bird flu. Which is not good. It's kind of scary if you have a flu, because you don't know if it's just a moderate flu or swine flu.

Todd theres no purple on that map but there is black?

I know here we have 8 confirmed cases which is scary because the one person lives 3hours from me. Shocked

They are all controled cases whatever that means and none are acually dieing. All flights are shut down to mexico from here to. Something bad though is that we have a program that brings in 300 Mexicans to work on Canadian farms every spring/summer and they just arrived yesterday. pale

Damn Mexican's!

but it has escalated overnight :supercry:

This is not the next bird flu; it's worse, and its in human's.

I'm doing some research my science lesson's, and this is seeming much worse than the media make it out to be :-.-:

WOW GUYS!!! That map is auto-updated by Wikipedia. When I posted it last night, it was only very small bits of black, now it's a whole country! Not good!!!

Also, some people could possibly have it, and they are only 4 hours drive from my house.

PostSubject: Re: Swine Flu   Sat May 02, 2009 3:00 am

The swine flu outbreak that has alarmed the world for a week now appears less ominous, with the virus showing little staying power in the hardest-hit cities and scientists suggesting it lacks the genetic fortitude of past killer bugs.
President Barack Obama even voiced hope Friday that it may turn out to be no more harmful than the average seasonal flu.
In New York City, which has the most confirmed swine flu cases in the U.S. with 49, swine flu has not spread far beyond cases linked to one Catholic school. In Mexico, the epicenter of the outbreak, very few relatives of flu victims seem to have caught it.
A flu expert said he sees no reason to believe the virus is particularly lethal. And a federal scientist said the germ's genetic makeup lacks some traits seen in the deadly 1918 flu pandemic strain and the more recent killer bird flu.
Still, it was too soon to be certain what the swine flu virus will do. Experts say the only wise course is to prepare for the worst. But in a world that's been rattled by the specter of a global pandemic, glimmers of hope were more than welcome Friday.
"It may turn out that H1N1 runs its course like ordinary flus, in which case we will have prepared and we won't need all these preparations," Obama said, using the flu's scientific name.
The president stressed the government was still taking the virus very seriously, adding that even if this round turns out to be mild, the bug could return in a deadlier form during the next flu season.
New York officials said after a week of monitoring the disease that the city's outbreak gives little sign of spreading beyond a few pockets or getting more dangerous.
All but two of the city's confirmed cases so far involve people associated with the high school where the local outbreak began and where several students had recently returned from Mexico.
More than 1,000 students, parents and faculty there reported flu symptoms over just a few days last month. But since then, only a handful of new infections have been reported only eight students since last Sunday.
Almost everyone who became ill before then are either recovering or already well. The school, which was closed this past week, is scheduled to reopen Monday. No new confirmed cases were identified in the city on Friday, and Mayor Michael Bloomberg said the outbreak in New York had so far proved to be "a relatively minor annoyance."
In Mexico, where swine flu has killed at least 16 people and the confirmed case count has surpassed 300, the health secretary said few of the relatives of 86 suspected swine flu patients had caught the virus. Only four of the 219 relatives surveyed turned up as probable cases.
As recently as Wednesday, Mexican authorities said there were 168 suspected swine flu deaths in the country and almost 2,500 suspected cases. The officials have stopped updating that number and say those totals may have even been inflated.
Mexico shut down all but essential government services and private businesses Friday, the start of a five-day shutdown that includes a holiday weekend. Authorities there will use the break to determine whether emergency measures can be eased.
In the Mexican capital, there were no reports of deaths overnight the first time that has happened since the emergency was declared a week ago, said Mayor Marcelo Ebrard.
"This isn't to say we are lowering our guard or we think we no longer have problems," Ebrard said. "But we're moving in the right direction."
The U.S. case count rose to 155 on Friday, based on federal and state counts, although state laboratory operators believe the number is higher because they are not testing all suspected cases.
Worldwide, the total confirmed cases neared 600, although that number is also believed to be much larger. Besides the U.S. and Mexico, the virus has been detected in Canada, New Zealand, China, Israel and eight European nations.
There were still plenty of signs Friday of worldwide concern.
China decided to suspend flights from Mexico to Shanghai because of a case of swine flu confirmed in a flight from Mexico, China's state-run Xinhua News Agency reported.
And in Hong Kong, hundreds of hotel guests and workers were quarantined after a tourist from Mexico tested positive for swine flu, Asia's first confirmed case.
Evoking the 2003 SARS outbreak, workers in protective suits and masks wiped down tables, floors and windows. Guests at the hotel waved to photographers from their windows.
Scientists looking closely at the H1N1 virus itself have found some encouraging news, said Nancy Cox, flu chief at the federal Centers for Disease Control and Prevention. Its genetic makeup doesn't show specific traits that showed up in the 1918 pandemic virus, which killed about 40 million to 50 million people worldwide.
"However, we know that there is a great deal that we do not understand about the virulence of the 1918 virus or other influenza viruses" that caused serious illnesses, Cox said. "So we are continuing to learn."
She told The Associated Press that the swine flu virus also lacked genetic traits associated with the virulence of the bird flu virus, which grabbed headlines a few years ago and has killed 250 people, mostly in Asia.
Researchers will get a better idea of how dangerous this virus is over the next week to 10 days, said Peter Palese, a leading flu researcher with Mount Sinai Medical School in New York.
So far in the United States, he said, the virus appears to look and behave like the garden-variety flus that strike every winter. "There is no real reason to believe this is a more serious strain," he said.
Palese said many adults probably have immune systems primed to handle the virus because it is so similar to another common flu strain.
As for why the illness has predominantly affected children and teenagers in New York, Palese said older people probably have more antibodies from exposure to similar types of flu that help them fight off infection.
"The virus is so close," he said.
In the United States, most of the people with swine flu have been treated at home. Only nine people are known to have ended up in the hospital, though officials suspect there are more.
In Mexico, officials have voiced optimism for two days that the worst may be over. But Dr. Scott F. Dowell of the CDC said it's hard to know whether the outbreak is easing up in Mexico. "They're still seeing plenty of cases," Dowell said.
He said outbreaks in any given area might be relatively brief, so that they may seem to be ending in some areas that had a lot of illness a few weeks ago. But cases are occurring elsewhere, and national numbers in Mexico are not abating, he said.
A top Mexican medical officer questioned the World Health Organization's handling of the early signs of the swine flu scare, suggesting Thursday that a regional arm of the WHO had taken too long to notify WHO headquarters of about a unusually late rash of flu cases in Mexico.
The regional agency, however, provided a timeline to the AP suggesting it was Mexico that failed to respond to its request to alert other nations to the first hints of the outbreak.
The Mexican official, chief epidemiologist Dr. Miguel Angel Lezana, backtracked Friday, telling Radio Formula: "There was no delay by the Mexican authorities, nor was there any by the World Health Organization."
In the U.S., Obama said efforts were focused on identifying people who have the flu, getting medical help to the right places and providing clear advice to state and local officials and the public.
The president also said the U.S. government is working to produce a vaccine down the road, developing clear guidelines for school closings and trying to ensure businesses cooperate with workers who run out of sick leave.
He pointed out that regular seasonal flus kill about 36,000 people in the United States in an average year and send 200,000 to the hospital.

Everyone always messes up their numbers. In a Mexican television report, they said around 50. The CDC (Center for Disease Control) only said about 20 people died im Mexico. One toddler died in the US after returning from Mexico.

I read that theres bin no outbreaks outside of North America and here in Alberta we have had the first case of a human giveing to pigs. A guy went to Mexico and passed it onto pigs at a pig farm its pretty bad now they should shoot all of them now to contain it.
